Résumé :

Emerging hardware devices (e.g., NVMe SSD, RISC-V, etc.) open new opportunities for improving the overall performance of computer systems. In addition, the applications try to fully utilize hardware resources to keep up with those improvements. However, these trends can cause significant file system overheads (i.e., fragmentation issues). In this paper, we first study the reason for the fragmentation issues on an F2FS file system and present a new tool, called FragTracer, which helps to analyze the ratio of fragmentation in real-time. For user-friendly usage, we designed FragTracer with three main modules, monitoring, pre-processing, and visualization, which automatically runs without any user intervention. We also optimized FragTracer in terms of performance to hide its overhead in tracking and analyzing fragmentation issues on-the-fly. We evaluated FragTracer with three real-world databases on the F2FS file system, so as to study the fragmentation characteristics caused by databases, and we compared the overhead of FragTracer. Our evaluation results clearly show that the overhead of FragTracer is negligible when running on commodity computing environments.

Résumé :

In a cloud platform, the monitoring service has become a necessary infrastructure to manage resources and deliver desirable quality-of-service (QoS). Although many monitoring solutions have been proposed in recent years, how to mitigate the overhead of monitoring service is still an opening issue. This article presents an adaptive monitoring framework, in which a traffic prediction model is introduced to estimate short-term traffic overhead. Based on this prediction model, a novel algorithm is proposed to dynamically change the sampling frequency of sensors so as to achieve better tradeoffs between monitoring accuracy and overhead. Also, a monitoring topology optimization mechanism is incorporated which enables to make more cost-effective decisions on monitoring management. The proposed framework is tested in a realistic cloud and the results indicate that it can significantly reduce the communication overhead when performing monitoring tasks for multiple tenants.

Résumé :

Abstract Overhead lines for wind power transmission in the southern region have the characteristics of large tower-line elevation, across thick ice areas, harsh natural environments, and difficult maintenance. Unpredictable line breakage accidents often occur, affecting the stability of the social power supply. This paper designs and introduces a technology based on intelligent perception technique for online monitoring of the earth wire, which can realize long-term real-time online monitoring of the state of the earth wire of overhead lines and solve the problem of line monitoring from wind power transmission and fault inspection and troubleshooting. Now the test and monitoring work of an overhead transmission line has been completed during the ice period, and the test results show that the technology has good monitoring performance.

Résumé :

Abstract In order to evaluate the vibration state of the overhead line, the φ-OTDR (phase-sensitive optical time-domain reflectometry) is applied to the vibration monitoring for the optical fiber composited in overhead transmission line. The principle of φ-OTDR and the IQ demodulation algorithm is introduced. Common mono-mode dark optical fiber simulates the optical fiber composited in an overhead line. The sinusoidal vibration is applied to the optical fiber using an arbitrary waveform generator and piezoelectric ceramic transducer (PZT). The vibration status in the optical fiber is measured by optical fiber vibration monitoring system using φ-OTDR. The result reveals that this system can demodulate the vibration applied to the optical fiber. This paper provides a reference for vibration monitoring optical fiber composite overhead lines.

Résumé :

Abstract In order to ensure the safe and stable operation of overhead transmission and distribution lines, the WSN network is used to optimize the line condition monitoring method design. In this paper, considering the connection mode of overhead transmission and distribution lines, a line equivalent model is constructed. The model configures the WSN network through the installation of sensor equipment. The WSN network is used to collect and transmit the operation data of overhead transmission and distribution lines, calculate the monitoring parameters such as voltage imbalance and current detuning, and finally get the visual monitoring results of line status. Compared with the traditional monitoring methods, it is concluded that the monitoring error of voltage imbalance and current detuning by the optimized design method is reduced by 1.15kV and 2.94kA, which effectively improves the monitoring accuracy of line operation.

Résumé :

The stationary hierarchical network faces considerable challenges from hotspots and faster network breakdowns, especially in smart monitoring applications. As a solution to this issue, mobile sinks were recommended since they are associated with huge and balanced ways to transfer data and energy across the network. Again, due to the mobile sink node advertisement around the network latency and the energy utilization overheads introduced across the network, ring routing reduces the control overhead while preserving the benefits of the mobile sink, thereby optimizing the energy and improving the network life span. Consequently, we suggested a novel, distributed advanced ring routing strategy, in this work, for the mobile wireless sensor network. Extensive simulations and performance evaluation, in comparison to previous distributed mobile approaches, reveal a 37% and 40% boost in the network throughput and end-to end delay, respectively. Additionally, the lifespan of a network is determined by the control overhead and energy demand.

Résumé :

This paper is for real-time monitoring sag problem of overhead lines, modeling two kinds of models with the state equation of catenary line and parabolic method, which are based on fiber grating sensing technology and take advantage of the conversion relationship of overhead line length between different states. The performance comparative analysis is carried out between the two models and currently relatively mature angle method. Experimental measuring results show that under the same conditions, the monitoring results of two models are very near to the monitoring results of angle method. But relatively speaking, monitoring results of the catenary model are more accurate. The accuracy of models can meet the project requirements and two models both can monitor overhead lines sag effectively in real time.

Résumé :

This paper presents different methods for overhead transmission line monitoring and the calculation of dynamic line rating. Some of these techniques are based on the reading or the prediction of the whole set of meteorological variables involved in the corresponding equations, whereas other methods use direct or indirect measurements of the conductor temperature. Additionally, a correction method will be described for incomplete monitoring situations. Finally, a real case study is presented for a 220-kV overhead line, where a double monitoring technique is considered for the calculation of the dynamic line rating, with a remarkable improvement in the utilization of the assets, compared to the seasonal rating. Keywords: Dynamic line rating, overhead transmission lines, grid operation and planning, electric power system monitoring.

Résumé :

This paper is for real-time monitoring ice thickness problem of overhead lines, modeling the sag difference monitoring model, which is based on fiber Bragg grating (FBG) sensing technology and parabolic method. The model takes advantage of the overhead line sag difference constant of two monitoring points, and achieves absolute stress change values, which effectively offset various factors, such as the wind load and thermal expansion and contraction, in the impact of the model. The performance comparative analysis is carried out between the results of the model and synchronous monitoring results of vernier caliper. Experimental measuring results show that under the same conditions, the similarity of results between two methods is very high. The accuracy of monitoring results of the model can meet the project requirements and it can monitor ice thickness of overhead lines effectively in real time.

Résumé :

Present icing monitoring system mainly depends on detecting the meteorological parameters and dynamic characteristics of the structure of the overhead icing line. However, all these systems need additional equipments for data collection. This paper provides a new method based on voltage and current of both ends of the line and discriminates the icing region and its severity via the change of active power and reactive power. It requires the voltage and current serving as signal source which is provided by the data collecting device on the both ends of lines. In this way it can accomplish the Monitoring task of icing transmission.

Résumé :

Mechanical deformations when a wire is stretched causes its rotation around its axis, which allows obtaining additional information about the wire behavior in an overhead transmission line and considering it no longer as a group of sections from one span but as a whole interconnected section with redistribution of mechanical loads between spans. To determine the tensile strength of wire by its torsion, a method for determining the mechanical parameters of an overhead transmission line was developed. It is based on the inclinometric method and the theory of force calculation of steel ropes. This technique takes into account the torsion, the angle of inclination and the wire temperature. The technique is implemented in the system for monitoring the status of overhead power lines. It takes into account the torsion angle of the wire and helps to prevent emergencies on the overhead power line by determining the tensile strength of the wire, checking for defects in wires of the overhead power line and defects in the suspension armature. The monitoring system includes control devices, data collection and data processing center, a dispatcher software package. Control devices are installed directly on the wire/ground wire of an overhead power line and are used to measure the angle of rotation, the angle of inclination and the wire temperature. The data collection and data processing station processes them according to the developed methodology in specialized software. The system for monitoring the status of overhead power lines based on the inclinometric method helps to prevent emergencies and reduce the economic costs of maintaining and restoring overhead power lines.

Résumé :

Environmental monitoring plays a vital role in environmental protection, especially for the management and conservation of natural resources. However, environmental monitoring data is usually difficult to resist malicious attacks because it is transmitted in an open and insecure channel. In our paper, a new data sharing scheme is proposed by using attribute-based encryption, identity-based signature and cloud computing technology to meet the requirements of confidentiality, integrity, verifiability, and unforgerability of environmental monitoring data. The monitoring equipment encrypts the monitored environmental data and uploads it to the environmental cloud server. Then, monitoring users can request access to the environmental cloud server. If the monitoring user meets the access policy, the plaintext is finally obtained through the fog node decryption. Our proposal mainly uses attribute-based encryption technology to realize the privacy protection and fine-grained access control of monitoring data. The integrity and unforgeability of the monitoring data are ensured by the digital signature. In addition, outsourcing computing technology saves the computing overhead of monitoring equipment and monitoring users. The security analysis illustrates that our proposal can achieve security purposes. Finally, the performance of our proposal and related schemes is evaluated from the aspects of communication overhead and computing overhead. The results indicate that our proposal is secure and efficient in environmental monitoring.

Résumé :

The issues of environmental impact of high-voltage transmission lines are becoming relevant in connection with the development of electrical networks of high voltage 110, 220, 330 kV, extra-high voltage (EHV) 500-750 kV and ultra-high voltage 1150 kV. The harmful effect of electric and magnetic fields on living organisms and, first of all, on humans, manifests itself only at very high voltages in the wires of the overhead line (OH) phases, and is dangerous when working under voltage. The direct influence of the electromagnetic field of lines on a person is associated with an effect on the cardiovascular, central nervous systems and other organs. The harmful effects of a person's stay in a strong electric field depend on the strength of the field and on the duration of its exposure. Software has been developed for modeling electromagnetic compatibility, characteristics of power losses to the corona from the voltage impact on the environment. The results of simulation of corona losses are presented on the example of a 500 kV overhead line, electric field voltage and active energy losses due to radio interference. Keywords: environmental impact, overhead power lines, electric field strength, corona losses, radio interference, acoustic noise, electromagnetic compatibility

Résumé :

Monitoring services are essential for advanced, reliable NoC systems. They should support traffic management, system reconfiguration and fault detection to enable optimal performance and reliability of the system. The paper presents a thorough description of NoC monitoring structures and studies earlier works. A distributed monitoring structure is proposed and compared against the structures presented in previous works. The proposed distributed network monitoring system does not require centralized control, is fully scalable and does not cause significant traffic overhead to the network. The distributed structure is in line with the scalability and flexibility of the NoC paradigm. The paper studies the monitoring structure features and analyzes traffic overhead, monitoring data diffusion, cost and performance. The advantages of distributed monitoring are found evident and the limitations of the structure are discussed.

Abstract On the basis of quality control methods, the analysis of the causes of technological disturbances (accidents) on overhead power lines was carried out. In particular, the Ishikawa diagram, the Pareto diagram were developed, which made it possible to systematize the main causes of technological violations. The necessity of monitoring the indicators of the reliability of the functioning of overhead power transmission lines by means of information-measuring systems has been substantiated. The structure of an information-measuring system for monitoring parameters that have a negative impact on the functioning quality of overhead power transmission lines is proposed. The proposed system is aimed at ensuring the reliability of the electrical networks operation and improving the quality indicators of services provided to consumers for the transmission of electrical energy.

Résumé :

When the overhead transmission line is galloping, a variety of natural disasters occur on the role of the natural conditions, the vibration of conductor is one of the more serious harm to the power system. Over the past decade, as the construction of EHV and UHV, wire cross-section, tension, suspension height and span of overhead transmission lines are increasing, and hence the number of conductor vibration is significantly increased. Vibration in a large scale will led to frequent tripping or even broken line or tower collapses, which cause large area power failures and impact security and stability operation. Online monitoring method for overhead transmission line dancing is mostly needed to add additional equipment, however, once situated on the route environment overlying ice or high winds and other inclement weather, online monitoring is difficult to achieve. This paper presents a method, which is made correlation analysis based on the voltage and current acquired from both ends of the transmission lines, online monitoring of line galloping can be achieved.

Résumé :

Abstract During the continuous operation of the distribution network, dirt often accumulates on the surface of insulators. Once encountering a humid climate environment, it may cause accidental discharge, leading to the occurrence of flashover pollution accidents. In order to effectively monitor this issue, this study adopted a monitoring method based on acoustic emission technology. This article introduces the discharge process and acoustic emission phenomenon of insulators in overhead distribution networks under pollution conditions. By using emission signal detection devices, acoustic signals generated during insulator discharge are captured. And the wavelet denoising algorithm was used to process its signal, based on which the discharge characteristics of insulator pollution in the overhead distribution network were extracted. The emission amount of insulator pollution in the overhead distribution network was determined according to the set threshold, achieving monitoring of pollution emissions. The results indicate that the proposed method can accurately monitor the discharge of insulators in overhead distribution networks, provide scientific basis for timely maintenance measures, and improve the operational safety and reliability of distribution networks.

Résumé :

THE RELEVANCE of the research lies in expanding the technical capabilities of location monitoring of overhead power lines by developing a method for connecting location equipment to them in the absence of standard high-frequency processing of lines.TARGET. Consider the problems of connecting location monitoring equipment to the lightning arrester cable of overhead power lines to input a probing pulse signal and observe reflected signals, while ensuring the electrical safety conditions of the system. Compare the efficiency of location monitoring with a standard connection of the locator to a phase wire through high-frequency processing of the line and when connected to a line lightning arrester cable. Carry out a study of the conditions for location monitoring of power lines in various grounding modes of the lightning arrester cable. Investigate the possibility of operating a locator through a lightning arrester cable to detect faults on the line by observing the signal reflected from the fault location.METHODS. The assigned tasks were solved by modeling. A simulation model of standard high-frequency processing of overhead power lines with a voltage of 35–750 kV was used in the PSCAD software environment. The model has the ability to connect location monitoring equipment to phase wires and lightning arrester cable, and record signals both at the beginning and at the end of the power line. By exciting a pulse signal in one wire of the line, due to inductive coupling, the signals propagate along all phase wires and the lightning arrester cable.RESULTS. The article substantiates the relevance of the topic and examines the features of the influence of various grounding modes of the lightning arrester cable on the efficiency of location monitoring of the line. A comparison was made of the experimental signals of location monitoring of power lines, with a standard connection of the locator to a phase wire through high-frequency processing of the line, with the signals of a simulation model when connecting the locator to phase wires and to a lightning arrester cable.CONCLUSION. The introduction of technology for location monitoring of power lines using lightning arrester cable will increase the reliability of substations in Russia and substations in neighboring countries. At the same time, due to the additional organization of location monitoring on power lines that do not have high-frequency processing, the number of controlled substations will be significantly increased. The substations will be provided with modern diagnostic equipment, in the form of an intelligent location system for monitoring power lines, which increases the uninterrupted operation of their operation under normal and extreme operating conditions.

Résumé :

The results of a study using an artificial thunderstorm cell of the possible influence of incomplete ascending discharges from concentrated model elements of overhead line monitoring systems on their functioning in the electric field of a thundercloud and/or lightning are presented. It is shown that ascending incomplete discharges (streamers and/or leaders) are formed from the model elements of the overhead line monitoring system (sensors, receiving and transmitting devices of a concentrated type), which can affect the functioning of such devices, including due to the fact that frequencies close to the operating frequencies of the elements of the overhead line monitoring system are present in the spectrum of their currents. It is established that the spectral characteristics of incomplete streamer and leader discharges formed from model elements of sensors and of receiving and transmitting devices of the monitoring system under the influence of an artificial lightning cell include frequency ranges close to the frequency ranges of analog-to-digital converters of sensors and data transmission devices over a high-frequency channel of concentrated monitoring systems. The essential role of the streamer corona on the formation of the ultrahigh-frequency component of the current pulse of incomplete discharges is revealed. The obtained results can help to ensure lightning protection of monitoring systems in a real thunderstorm situation.

Résumé :

Ice buildup monitoring is essential to prevent wire breakage on overhead power lines. Conventional telemetry systems which are based on load cell sensors have some drawbacks as reflected in this paper. We suggest an innovative device for contactless ice buildup monitoring of overhead power line wires video recording the power line clearance. A specific algorithm for detecting the lowest point of wire sag has been provided. Also, we analyze a possibility of indirect contact sensor-free measurements of a wire temperature when the wire is being covered by icy deposits. A specific buildup type can be determined comparing a dew point and desublimation point as shown in this paper.

Résumé :

This paper introduces the broadband over power lines-enhanced network model (BPLeNM) that is suitable for efficiently delivering the generated data of wireless sensor networks (WSNs) of overhead high-voltage (HV) power grids to the substations. BPLeNM exploits the high data rates of the already installed BPL networks across overhead HV grids. BPLeNM is compared against other two well-verified network models from the relevant literature: the linear network model (LNM) and the optimal arrangement network model (OANM). The contribution of this paper is threefold. First, the general mathematical framework that is necessary for describing WSNs of overhead HV grids is first presented. In detail, the general mathematical formulation of BPLeNM is proposed while the existing formulations of LNM and OANM are extended so as to deal with the general case of overhead HV grids. Based on these general mathematical formulations, the general expression of maximum delay time of the WSN data is determined for the three network models. Second, the three network models are studied and assessed for a plethora of case scenarios. Through these case scenarios, the impact of different lengths of overhead HV grids, different network arrangements, new communications technologies, variation of WSN density across overhead HV grids, and changes of generated WSN data rate on the maximum delay time is thoroughly examined. Third, to assess the performance and the feasibility of the previous network models, the feasibility probability (FP) is proposed. FP is a macroscopic metric that estimates how much practical and economically feasible is the selection of one of the previous three network models. The main conclusion of this paper is that BPLeNM defines a powerful, convenient, and schedulable network model for today’s and future’s overhead HV grids in the smart grid (SG) landscape.

Résumé :

In conventional sports training, coaches record and observe athletes' sports data and judge whether it is reasonable based on their own experience. This qualitative analysis method is highly subjective, has large errors, and is susceptible to interference. To solve the above problems, the design of the sports training system under the wireless sensor network and the research of movement monitoring and recognition become very important. This article aims to study the design of sports training system and the monitoring and recognition of actions under the wireless sensor network technology. This paper simulates the implementation of the proposed data collection protocol and the two basic protocols, the direct transfer algorithm and the flooding algorithm, and compares the protocol proposed in this paper with the other two algorithms in terms of average information transmission success rate and average network overhead. Among them, the average information transmission success rate represents the ratio of the number of messages successfully arriving at the base station to the total amount of information generated by all nodes, and the average network overhead represents the average number of messages sent by each node. Experimental results show that the data collection protocol proposed in this paper can dynamically provide different transmission qualities for information of different importance levels, effectively reducing network overhead, and the reduced overhead is 11% of the original.
