Full textAbstract:
Circuit breakers with automatic transfer switches (ATS) are designed in such a way that when the voltage disappears during a short-circuit (SC) in the ring network line, the ATS device is triggered. At the same time, its switch is turned on at short-circuit, then it is turned off with acceleration. Even a shortterm switching on of the automatic transfer switch for a sustained short-circuit leads to emergency situations [1,2]. The electrical equipment of the ring network spare line is exposed to high emergency short-circuit currents, and the consumers powered by the spare transformer are turned off. It is possible to minimize and eliminate the damages caused by the above mentioned cases by inhibiting the switching on of the circuitbreaker of the automatic transfer switch.

Full textAbstract:
An automatic stage transition converter for an inductive power transfer system is presented in this paper. An effective control strategy with two working stages of independent energy injection stage and free resonance stage is employed in the proposed converter. With the automatic stage transition strategy, when the frequency of the resonance network changes, the ending time of the free resonance stage is automatically determined. At the same time, the phase angle of the free resonance stage is automatically set as half a resonant cycle. As the stage transition is not triggered by the switches, the switch motion can be executed in advance of the transition moments. Time margins are offered for every switch in the converter, which make the switching moments of the switches flexible and the control simple. Another feature of this converter is that during the energy injection stage, the energy is injected into the inductor independently. Therefore, the input power can be easily regulated by adjusting the energy injection time. A prototype for the converter and the inductive power transfer system was implemented experimentally. From the experimental results, the automatic stage transition and power regulation capability of the proposed converter are verified. The switches all operated at the soft switch condition. When the energy injection time was adjusted from 10 μs to 25 μs, the output power changed from 143 W to 740 W.

Full textAbstract:
Automatic sectionalizing and redundancy of power transmission lines is one of the conditions for network intellectualization and can significantly reduce the power supply interruption time for rural consumers. However, both sectionalizing and redundancy of power transmission lines in 0.4 kV electric networks are used extremely limitedly since there are no sufficiently effective methods and technical means for their implementation. This article presents a method to automatically deactivate the automatic load transfer switch when restoring the normal network operation mode. The paper considers the implementation of the method on the example of damage occurring in the network where power is supplied to consumers from two power sources using an automatic load transfer switch and two sectionalizing units. A device is developed which allows implementing the developed method of automatic load transfer switch deactivation. The device consists of sectionalizing unit, automatic load transfer switch, voltage presence sensor, power direction sensor, memory element, repeater element, element AND and 3 elements NOT. The work of the device is described. The proposed method for automatically disconnecting the automatic load transfer switch in order to return the consumers’ power supply circuit to its initial state solves the problem of eliminating unreasonable power supply interruptions for consumers.

Full textAbstract:
In recent years, a new type of 380V low voltage fixed circuit breakers are used in newly built substations. Fixed circuit breakers without chassis only have two states. They are on and off. They can not provide a clear break point in circuit. So Their isolation function is not obviously. Low voltage equipment in Hub substations should have automatic mutual transfer function. Recently Automatic Transfer Switch (ATS) is often chosen in the newly built digital substation, intelligent substation or large hub substations. Automatic Transfer Switch has interlocking function to avoid the collision of two different power. With the popularize of new equipment such as the 380V fixed circuit breaker and Automatic Transfer Switch, the operation and management of low-voltage equipment in substations puts forward higher requirements as well. The conclusion contains the better ways in operation and maintenance of these new low-voltage equipment.

In line with the development of science and technology today, especially in the field of electricity brought many changes in the use of electricity. Electricity is currently needed both industrial and non-industrial. Electricity needs are currently provided by PLN as the main power source. The flow of electricity from the electricity grid is not always continuous in its distribution, one day there must be a blackout that may be caused by interference with the transmission system or distribution system. To anticipate this outage, it is necessary to design an automatic control called an automatic transfer switch and to prepare a backup source, a 2000-watt power inverter. Automatic transfer switch is electrical equipment that functions as a controller of the process of switching the PLN electricity supply to the inverter power supply or vice versa automatically. In the operation of this automatic transfer switch can be operated manually and automatically. Where is in automatic mode, if there is a power outage on PLN this tool is useful for turning on and connecting the power inverter to the load automatically. When PLN revives, this tool will transfer the power source to the load from the power inverter to the PLN electricity. At this time technological advances are developing very rapidly, technology is an inspiration so that life in the world becomes lighter, easier and practical.

Rejosari Village has enormous potential, namely there are many abundant rice fields around the settlement. Rejosari Village is located in Kebonsari District, Madiun Regency. Farmers in Kebonsari village have used a water pump that is used in the rice field irrigation system. However, until now many farmers still use PLN as the main source in running electric motors for irrigation systems. So that farmers often experience power outages due to lack of electrical power. Community service activities through a partnership program for farmer groups in Rejosari Village, Kebonsari District, Madiun Regency are focused on making Automatic Transfer Switch (ATS) panels to convert electrical energy source switches from PLN to sources of solar energy from solar panels. This ATS panel contains a switch that can replace the source of electrical energy in an electric motor that was originally from PLN into an energy source from the Solar Panel. The hope is that with this community service program, farmer groups can obtain electrical energy to power the irrigation system and not depend on PLN. This PKM can also reduce the cost of electricity rates incurred by farmers.

ABSTRAKPotensi akan energi surya yang besar di Indonesia mendorong masyarakat untuk memanfaatkan energi tersebut. Umumnya energi listrik tersebut akan disimpan pada baterai dan semakin besar persentase dari Depth of Discharge (DOD) akan mempersingkat umur baterai. Sistem Automatic Transfer Switch (ATS) melakukan pemilihan secara otomatis, namun bekerja tanpa memperhatikan kondisi sistem panel surya sehingga mempersingkat umur baterai. Pada penelitian ini dilakukan integrasi antara ATS dengan sistem panel surya yang disebut Integrated Transfer Switch (ISTS). Sistem ISTS ini dirancang untuk melakukan pembacaan data dengan sistem modular, koneksi antar modul dilakukan secara nirkabel dengan memanfaatkan sistem IoT. Perpindahan sumber menggunakan solid-state, proteksi berupa Fuse, dan layar TFT untuk menampilkan informasi telah dirancang pada ISTS. Namun ISTS memiliki keterbatasan penggunaannya karena diperlukan adanya sumber listrik cadangan. Tata letak komponen dirancang menghemat ruang dengan mempertimbangkan keamanan dan peletakan kabel-kabel diisolasi plastik Nylon 6 untuk mengurangi risiko terjadinya percikan listrik.Kata kunci: Panel surya, Depth of Discharge, ATS, umur baterai, ISTSABSTRACTThe great potential for solar energy in Indonesia encourages people to utilize this energy. Generally, this electrical energy will be stored in the battery, and the greater the percentage of Depth of Discharge (DOD) will shorten the life of the battery. The Automatic Transfer Switch (ATS) system makes the selection automatically but works regardless of the condition of the solar panel system, thus shortening the battery life. In this study, an integration between ATS and a solar panel system called the Integrated Transfer Switch (ISTS) was carried out. The ISTS system is designed to read data with a modular system, the connection between modules is done wirelessly by utilizing the IoT system. Source switching using solid- state, protection in the form of Fuse, and a TFT screen to display information has been designed on the ISTS. However, ISTS has limited use because it requires a backup power source. The layout of the components is designed to save space with safety in mind and laying the nylon 6 plastic insulated cables to reduce the risk of an electric spark.Keywords: Solar panel, Depth of Discharge, ATS, battery life, ISTS

In Pirak Mertosutan Hamlet, Sleman, Yogyakarta, there is a goat farm complex with about 600 m2. The intricate lighting comes from the National Electricity Company (PLN) and the Solar Home System (SHS). SHS is the primary energy source for lighting, while PLN is a secondary energy source that replaces it when the power supply from SHS goes out. So far, the transfer from SHS to PLN has been carried out by humans. This fact is considered inefficient because the SHS supply does not always die during the day. At night, the officers who move the difficulties have to go to the cage complex located relatively far from residential areas. To facilitate the transfer of energy sources from SHS to PLN and vice versa. It does not need to be done by officers. It is necessary to automatically install a means to automatically move the two sources automatically. This tool is the Automatic Transfer Switch (ATS). This tool can move the energy supply from SHS to PLN and vice versa. By considering the specifications used in the SHS in the farm complex, the ATS is made and then installed in the farm complex. After the installation is carried out, the functional test is carried out. The ATS installation test results show that the ATS can work according to the design; namely, when the SHS is off, the source used is automatically switched to PLN. When the SHS is on, the source that was using PLN will automatically switch to SHS.

Abstract The probabilistic model of a hospital electrical power system consisting of mains, an emergency power system and the automatic transfer switch with the generator starter are discussed in this paper. The reliability model is semi-Markov process describing two different units renewable cold standby system and switch. The embedded Semi-Markov processes concept is applied for description of the system evolution. Time to failure of the system is represented by a random variable denoting the first passage time of the process from the given state to the subset of states. The appropriate theorems of the Semi-Markov processes theory allow us to evaluate the reliability function and some reliability characteristics.

Herdoyo Wirawan, Arkhan Subari, in this paper explain that the DC source at a PLN substation has a very important role in the smooth operation of the substation itself in a protection and serving the electricity needs of customers. This DC source serves to drive protective equipment, emergency lighting, and others.When the DC source on the receptor is interrupted, the dc source used is a DC source that comes from the battery. When certain conditions cannot guarantee whether the battery capacity is capable of supporting the load borne by the battery, it must always be monitored with a voltage sensor. In order for the protective equipment to continue to work, when the rectifier from the PLN power supply is cut off, a voltage source from 12VDC batteries is used. Switching the voltage source between the rectifier and the battery is done automatically by using the ATS (Automatic Transfer Switch) circuit. When the DC source from the PLN electricity supply will return it will be detected by an optocoupler sensor which later ATS will automatically switch the voltage source again. Keywords: automatic transfer switch, rectifier, DC source, voltage sensorReferencesLestary, Wulan. 2015. Rancang Bangun Kunci Pintu Digital Berbasis Arduino Mega. Tugas Akhir Tidak Terpublikasi.

Full textAbstract:
In this work we showed the optimization of the spectral response of several optical elements in a silicon-based optical switch. Integrated thermal resistors induced a local heating of the components. The temperature increase, in turn, caused a thermal shift of the optical response of the component. In this manner, we aligned interleavers and micro-ring resonators to the International Telecommunication Union (ITU) channels, by using a stochastic method named Globalized Bounded Nelder-Mead (GBNM) to determine the proper temperatures. The optimization engine relied on the optical feedback from on-chip monitor photodiodes to drive these photonic elements into the wanted functioning condition. This method is suited for restoring the spectral response of optical elements impaired by fabrication inaccuracies. In the same way, it can be applied to tune in resonance active components, whose transfer function has one or more local optima. We proved the reliability of the GBNM method for the optimization of an integrated optical switch, with more than thousand optical components, each one interfaced with a thermal resistor driven by a dedicated electronic circuit. On the one hand, the GBNM guaranteed the automatic alignment of all active components on the chip, over multiple instances. On the other hand, the method allowed for the proper working of such a complex device.

Voltage dips are quite frequent and dangerous phenomenon, which can lead to disruption of the production process. Ensuring the stability of induction motors during voltage dips is an important task to ensure the continuity of the technological process, as well as to reduce material losses. THE PURPOSE. List the main causes of voltage dips. Develop a simulation model corresponding to a typical power supply scheme for an oil pumping station with a group of asynchronous motors as a load. Perform two series of calculations to determine the parameters of the electrical mode in case of voltage dips and the subsequent restoration of the voltage on the buses of the supply substation. METHODS. When solving the problem, the PSCAD software package was used. RESULTS. The article describes the relevance of the topic, the main causes of voltage dips are given. The simulation of voltage dips resulting from a short circuit on the substation equipment has been performed. A series of calculations were performed, differing from each other in the changed initial data: the place of occurrence of a short circuit, the time delay of automatic transfer of the reserve. The analysis of the obtained results is carried out. CONCLUSION. According to the test results, it can be seen that the decrease in voltage on the low voltage buses of substations after the operation of automatic transfer switch is the lower, the longer the time delay of automatic transfer switch. In this work, the maximum time delay was 7 seconds, while there was no violation of the stability of the induction motors. The need to study the operation of a group of asynchronous motors in case of accidents in an external electrical network is also determined.

The use of power line sectionalizing and power line redundancy in 0.38 kV networks entails the need to take into account the fact that currents and voltages can vary significantly at different points of the network. The article proposes a mathematical model to solve this problem. The mathematical model is based on the method of phase coordinates. Using mathematical modeling, the article determines the voltages and currents in the sections of the backup line after the automatic load transfer switch is activated.

Full textAbstract:
Microprocessor devices of fast-acting automatic transfer switch (FATS) are widely spread in modern net-works to increase the reliability of power supply of industrial plants in case of short-term violations of normal power supply mode. Presence of motor load in such networks requires minimizing the power interruption time to provide more favorable conditions for self-starting of electric motors. However, currently existing operation algorithms of measuring elements of FATS devices are based on the decomposition of the measured signal by using a Fourier integral, and require observation interval equals to the period of the industrial frequency. The known directional elements that are used in microprocessor-based FATS devices do not ensure reliable operation of the device with asymmetric and nearby fault. Therefore, the purpose of the work is to increase the speed of operation of the algorithms of the measuring elements of microprocessor devices of FATS, as well as to increase the reliability of the starting directional element in case of nearby fault and deep voltage drops. To achieve this goal the author uses the method of computer simulation. The method of a full-scale experiment on a laboratory bench to verify the obtained theoretical results is used. The author improves the algorithm to determine the orthogonal components of the measured current and voltage signals by integral averaging of instantaneous discrete values of the measured signals and their derivatives over the observation interval with a duration of less than a half-period of the industrial frequency. The algorithm of the operation of the starting directional element in case of deep voltage drops caused by nearby fault in both the external and internal power supply network has been improved by using the main power supply voltage from the added memory element of the pre-fault measurement cycle as a reference voltage to determine the power direction. The obtained results show that the proposed algorithm for the operation of the measuring elements will make it possible to obtain the value of the phase and amplitude of the measured signal in a time equals to 0,005 s. and use of an improved starting directional element makes it possible to increase its reliability in case of deep voltage drops and asymmetric short circuits. The proposed algorithms of operation of the measuring elements and the starting directional element can be used in FATS devices.

A pepper quality detection and classification model based on transfer learning combined with convolutional neural network is proposed as a solution for low efficiency of manual pepper sorting at the current stage. The pepper dataset was amplified with data pre-processing methods including rotation, luminance switch, and contrast ratio switch. To improve training speed and precision, a network model was optimized with a fine-tuned VGG 16 model in this research, transfer learning was applied after parameter optimization, and comparative analysis was performed by combining ResNet50, MobileNet V2, and GoogLeNet models. It turned out that the VGG 16 model output anticipation precision was 98.14%, and the prediction loss rate was 0.0669 when the dropout was settled as 0.3, learning rate settled as 0.000001, batch normalization added, and ReLU as activation function. Comparing with other finetune models and network models, this model was of better anticipation performance, as well as faster and more stable convergence rate, which embodied the best performance. Considering the basis of transfer learning and integration with strong generalization and fitting capacity of the VGG 16 finetune model, it is feasible to apply this model to the external quality classification of pepper, thus offering technical reference for further realizing the automatic classification of pepper quality.

After discussing some characteristics of spoken language as well as principal constraints operating on speech-to-speech translation, we will give a very brief overview of existing approaches, and then switch to the extended description of a sample solution within the VERBMOBIL-Project where transfer is assisted by a dialogue-act component. The last section describes how, with limited use of available information, transfer based on dialogue acts might result in new solutions for existing problems.

Terbatasnya energi fosil di Indonesia menyebabkan adanya pengembangan energi baru terbarukan. Energi terbarukan merupakan energi non-fosil yang berasal dari alam. Pemanfaatan energi surya bisa dilakukan dengan membangun Pembangkit Listrik Tenaga Surya (PLTS). Perencanaan PLTS menggunakan sistem on grid, sistem masih terkoneksi dengan jaringan PLN. Sistem dimanfaatkan sebagai backup untuk aliran listrik. Sistem akan bekerja secara otomatis ketika aliran listrik PLN terputus dengan memanfaatkan panel ATS (Automatic Transfer Switch). Pembangkit listrik tenaga surya sistem on grid ini cocok diterapkan di perumahan dengan memanfaatkan atap sebagai ruang untuk menyerap energi matahari. Sistem ini jika dipasang bersamaan dengan PLN akan mengurangi pengeluaran biaya listrik. Penerapan sistem atau prinsip kerja PLTS Grid Tie System ini dapat dijalankan dengan sistem kelistrikan PLN. Dalam sistem ini, jaringan listrik PLN berperan sebagai penyalur atau penghubung arus listrik yang berasal dari panel surya yang dialirkan pada beban. Dengan begitu pada siang hari, penggunaan listrik dapat memanfaatkan energi listrik dari sinar matahar dan pada malam hari karena tidak ada sinar matahari menyebabkan tidak ada produksi listrik dari solar panel, maka dapat tetap menggunakan arus listrik yang berasal dari PLN.
Perencanaan dilakukan dengan pemilihan komponen PLTS, beban yang dibutuhkan 900Watt, lama waktu penyinaran efektif 10 jam/hari. kemudian melakukan perhitungan komponen PLTS, menentukan tata letak penempatan panel surya dan panel ATS (Automatic Transfer Switch) yang digunakan untuk membackup apabila jaringan listrik PLN terputus.
Dari hasil pengukuran arus, tegangan dan daya di dalam rumah pada jam 07.00 sampai dengan 17.00 pada waktu cuaca cerah, yaitu sebelum Grid Tie Inverter dihubungkan ke jala-jala dihasilkan daya rata-rata, P=606,105Watt dan setelah Grid Tie dihubungkan ke jala-jala, P=292,63 Watt. Jadi penghematan daya beban di rumah yang dihasilkan sebesar 52 % dalam satu hari.
Limited fossil energy in Indonesia has led to the development of new and renewable energy. Renewable energy is non-fossil energy that comes from nature. Utilization of solar energy can be done by building a Solar Power Plant (PLTS). PLTS planning uses an on-grid system, the system is still connected to the PLN network. The system is used as a backup for electricity. The system will work automatically when the flow of PLN electricity is cut off by utilizing an ATS (Automatic Transfer Switch) panel. This on-grid solar power plant system is suitable for residential use by utilizing the roof as a space to absorb solar energy. This system if installed together with PLN will reduce expenditure of electricity costs. The application of the system or the working principle of the PLTS Grid Tie System can be run with the PLN electrical system. In this system, the PLN electricity network acts as a distributor or connector for the electricity that comes from the solar panels that are flowed to the load. That way during the day, the use of electricity can take advantage of electrical energy from the sun and at night because there is no sunlight it causes no electricity production from solar panels, it can still use the electric current that comes from PLN.
Planning is done by selecting the PLTS component, the load required is 900 Watt, the duration of effective irradiation is 10 hours / day. Then calculate the PLTS components, determine the layout of the placement of the solar panels and ATS (Automatic Transfer Switch) panels which are used to back up when the PLN electricity network is interrupted.
From the results of measuring currents, voltages and power in the house at 07.00 to 17.00 when the weather is clear, that is, before the Grid Tie Inverter is connected to the grid, the average power is generated, P = 606.105Watt and after the Grid Tie is connected to the grid mesh, P = 292.63 Watts. So, the resulting load power savings at home is 52% in one day

Simulation of transient and steady state modes of synchronous motors for the analysis of switching to backup power using mathematical model. Method. The methods of linear algebra, numerical optimization methods, methods of modeling and analysis of established and transient modes are used. Results. The mathematical model of the salient pole rotor and non-salient or cylindrical pole rotor synchronous motor is presented, which is presented in the form of a alternate scheme, which allows to take into account the effect of displacement of current and saturation of the non-salient pole rotor motor's magnetic core. A method for determining the parameters of the synchronous motor based on passport data is proposed, which allows to improve the accuracy of modeling in steady state and transient modes. The mathematical model is reduced to a three-phase coordinate system a, b, c of the stator winding. The rotor windings are modeled in the coordinates d, q. The results of mathematical modeling allow us to determine the magnitude of the shock currents and mechanical moments of the synchronous motor. It is shown that non-synchronous switching on of the synchronous motor, which occurs in case of automatic transfer switch, can lead to engine damage. Shock currents can also be dangerous to other power supply equipment. Thus, synchronous motors, if transfer switch is used, require synchronization before being connected to the network. Scientific novelty. The mathematical model of the synchronous motor was improved taking into account the displacement of current and saturation of the magnetic conduit, the method of determining the parameters of the mathematical model based on the passport data of the engine was improved, which allowed to increase the accuracy of the simulation and the reliability of the simulation results. The modes of power transfer switch are simulated and the values of shock current and shock mechanical moment of the engine are obtained. Practical meaning. The mathematical model of the synchronous motor allows to analyze the behavior of synchronous motors in interaction in the power supply system and to identify the dangerous states of synchronous motors that may occur during the transfer switching. The proposed model improves the accuracy of determination of the limits of dangerous states and improves the reliability of synchronous motors and power supply systems.

UPS (Uninterrupted power supply) is a basis for the observation equipments, and its reliability play a decisive role for the all tasks. Most of the observation stations are unattended, and their distribution is dispersive. So the maintenance of UPS is tedious and complicated, and it is difficult to achieve unified management and effective maintenance. In response to this situation, this paper proposes a UPS remote intelligent monitoring program. Through the monitoring data collection, remote data transmission, data output display and the control command transfer, this program can monitor the power supply capacity, load conditions and working status in the real-time, and achieve the function of automatic alarm and remote switch control. It completely changes the traditional decentralized management model and improves the level of scientific management of the UPS.

Full textAbstract:
Reconfigurable detectors with dynamically selectable sensing and readout modes are highly desirable for implementing edge computing as well as enabling advanced imaging techniques such as foveation. The concept of a camera system capable of simultaneous passive imaging and dynamic ranging in different regions of the detector is presented. Such an adaptive-autonomous detector with both spatial and temporal control requires programmable window of exposure (time frames), ability to switch between readout modes such as full-frame imaging and zero-suppressed data, modification of the number of pixel data bits and independent programmability for distinct detector regions. In this work, a method is presented for seamlessly changing time frames and readout modes without data corruption while still ensuring that the data acquisition system (DAQ) does not need to stop and resynchronize at each change of setting, thus avoiding significant dead time. Data throughput is maximized by using a minimum unique data format, rather than lengthy frame headers, to differentiate between consecutive frames. A data control and transmitter (DCT) synchronizes data transfer from the pixel to the periphery, reconfigures the data to transmit it serially off-chip, while providing optimized decision support based on a DAQ definable mode. Measurements on a test structure demonstrate that the DCT can operate at 1 GHz in a 65 nm LP CMOS process.

Full textAbstract:
Rumah sakit adalah tempat pelayanan publik yang sangat penting, dimana pelayanan tersebut tidak terlepas dengan kebutuhan listrik. Adapun kendala dari sistem kelistrikan RSUD ULIN yaitu masih menggunakan jaringan distribusi tegangan rendah, padahal jarak antara gardu PLN dengan gedung cukup jauh sehingga tegangannya droop. Akibatnya sangat mempengarui supply listrik kegedung tersebut, sehingga peralatan medik maupun non medik cepat mengalami kerusakan. Selain itu sistem beckup powernya masih partial artinya setiap gedung memiliki genset masing-masing sehingga jika genset tersebut bermasalah maka genset lain tidak bisa membantu supply listrik kegedung tersebut. Untuk mengatasi permasalahan tersebut, RSUD ULIN menggunakan distribusi jaringan listrik tegangan menengah sehingga permasalahan droop tegangan dapat teratasi kemudian sistem beckup listriknya sudah menggunakan sistem Automatic Transfer Switch (ATS) tegangan menengah yang dilengkapi dengan panel sinkrone full otomatis. Sistem backup listriknya sudah menggunakan managemen energi sehingga genset yang hidup menyesuaikan dengan beban yang ada di RSUD Ulin sehingga menghemat penggunaan bahan bakar dan mendukung efisiensi energi.Kata kunci : tegangan droop, distribusi jaringan listrik tegangan menengah, RSUD ULIN

Full textAbstract:
This paper introduces an open-source platform called ISOBlue HD for acquisition of context-rich data from agricultural machinery. We call these datasets context-rich, because they enable the identification of machine status and farming logistics by properly labeling, fusing, and processing the data. The system includes a single board computer, a cellular modem, local storage, and power-over-ethernet switch to sensors. The system allows remote diagnostics and access, automatic startup/shut down with vehicle operations, and uses Apache Kafka to enable robust data exchange. ISOBlue HD was deployed in a combine harvester during a 2019 wheat harvest for simultaneously capturing 69 million CAN frames, 230,000 GPS points, and 437 GB of video data, focusing on header status and operator actions over 84 h of harvest time. Analyses of the collected data demonstrate that contextual knowledge can be inferred on harvest logistics (paths, speeds, header status, material transfer) and sensor data semantics.

Full textAbstract:
Hotel Grand Elite Pekanbaru mendapat suplai daya listrik dari PLN sebesar 1250 kVA dan mempunyai tiga buah unit Generator-set (Genset) kapasitas 500 kVA sebagai back-up suplai daya listrik apabila terjadinya pemadaman listrik dari PLN. Namun demikian penggunaan genset tersebut tidak dapat melayani beban secara cepat dimana hal ini disebabkan adanya kerusakan pada rangkaian Automatic Transfer Switch (ATS). Untuk itu diperlukan rancangan sistem suplai daya tak terputus yang dapat menyuplai beban, khususnya beban emergency dengan menggunakan Uninterruptible Power Supply (UPS). Dari hasil penelitian diperoleh total beban emergency Hotel Grand Elite Pekanbaru sebesar 125,779 kVA terdiri dari beban lift 32,670 kVA dan beban Elite Fitnes Center 67,952 kVA sehingga diperlukan kapasitas UPS sebesar 150 kVA. Penambahan suplai daya UPS sangat cocok karena disamping sebagai solusi akibat kurangnya daya listrik ketika terjadi pemadaman dari PLN dan juga dapat memback-up beban emergency pada Hotel Grand Elite Pekanbaru. Kata kunci : Generator-set, Uninterruptible Power Supply

Kasus pemadaman listrik bergilir sudah menjadi masalah umum di Indonesia. Kebutuhan listrik semakin memuncak karena penggunaan energi listrik dapat menghidupkan berbagai peralatan rumah tangga dan industri. Saat ini, banyak terjadi pemadaman listrik secara bergilir karena kapasitas beban sudah melebihi kapasitas yang sudah ditentukan. Akibatnya, pasokan energi listrik menjadi tidak stabil, sehinga berdampak pada peralatan listrik rumah tangga.Akibat pemadaman listrik yang tidak menentu maka digunakan pemasok cadanan yang dapat bekerja ketika sumber daya utama tidak aktif atau disebut UPS (Uninterruptible Power Supply). UPS dapat menjadi energi cadangan listrik sementara pada saat terjadi pemadaman listrik sehina mengurangi dampak pada peralatan listrik rumah tanggaPada perancangan sistem ini, digunakan sumber solar cell 300WP(watt peak) yang digunakan untuk proses pengisian baterai 48V DC 45Ah dengan menggunakan buck-boost converter. Ketika sumber utama PLN tidak aktif ATS(Automatic Transfer Switch) secara otomatis akan memindahkan catu daya dari baterai. Dari sumber baterai digunakan inverter satu fasa untuk mencatu beban rumah tangga sebesar 50W 220V AC.
