Abstract:
The purpose of the article is to analyze the damage rate of overhead power transmission lines (OPL) in medium-voltage electrical distribution networks of the Irkutsk region. The established International Indices that determine the level of reliability of the functioning of electric networks are considered, and information on the compliance of the condition of electric networks in Russia with these indices is analyzed. Analytical information on the damage rate of elements of these networks and their causes in Europe, America, and Russia is presented. The emphasis is placed on the fact that the most common damage is characteristic of overhead power lines, especially 6–10 kV lines. As an object of research, two branches of the Irkutsk electric grid company (IEC) were taken, one of which provides electricity to rural consumers, the other — mainly to consumers residing in the territory of the city Irkutsk. The characteristics of these electric networks, their territorial location and basic technical data are presented. To conduct analytical monitoring of the level of reliability of overhead power transmission lines, logs of disconnection of the Eastern and Southern electric networks of the IEC over a long-term period were used. On the basis of this information, tables of failures and their consequences in the studied electrical networks were compiled for monthly average data over the period under examination for various causes of damage. To plot time diagrams of the parameters under examination, computer programs were compiled in the Matlab system, the use of which made it possible to obtain visualization of changes in failures for various reasons for the electrical networks under consideration. The information on the time of power supply interruptions in these networks, as well as the amount of electricity underutilized by consumers during these interruptions and its cost are analyzed. It is shown that in the electric networks under consideration, most of the power failures are related to the territorial dispersion of these networks, and the low level of equipment controls and insufficient qualification of operating personnel, as evidenced by the significant number of failures for unknown reasons. Besides, a significant part of the failures is due to damage to the overhead line wires, switching equipment and the effect of wind load. Recommendations for improving the condition of power transmission lines and a number of measures aimed at improving the level of reliability of power supply are presented.

Abstract:
Power systems in general supply consumers with electrical energy as economically and reliably as possible. Reliable electric power systems serve customer loads without interruptions in supply voltage. Electric power generation facilities must produce enough power to meet customer demand. Electrical energy produced and delivered to customers through generation, transmission and distribution systems, constitutes one of the largest consumers markets the world over. The benefits of electric power systems are integrated into the much faster modern life in such extent that it is impossible to imagine the society without the electrical energy. The rapid growth of electric power distribution grids over the past few decades has resulted in a large increment in the number of grid lines in operation and their total length. These grid lines are exposed to faults as a result of lightning, short circuits, faulty equipment, mis-operation, human errors, overload, and aging among others. A fault implies any abnormal condition which causes a reduction in the basic insulation strength between phase conductors or phase conductors and earth, or any earthed screens surrounding the conductors. In this paper, different types of faults that affected the electric power distribution grid of selected operational districts of Electricity Company of Ghana (ECG) in the Western region of Ghana was analyzed and the results presented. Outages due to bad weather and load shedding contributed significantly to the unplanned outages that occurred in the medium voltage (MV) distribution grid. Blown fuse and loose contact faults were the major contributor to unplanned outages in the low voltage (LV) electric power distribution grid.

Abstract:
Power Quality phenomena in a broad sense, stationary and transient, are considered focusing on railway applications: dc and ac traction lines are considered, identifying the main sources (fixed, like substations, and moving, like vehicles), their characteristic emissions, how they propagate and combine along the traction lines and back to the three-phase ac supply lines. The analysis covers the railway standards applicable to the traction line and the industrial standards applicable to the ac feeding lines. The peculiarity of railway applications, that is the presence of moving distorting loads interconnected by a non-ideal transmission line and characterized by variable operating conditions and by the superposition of multiple sources with different dynamics, requires specific processing, analysis and visualization methods, that are addressed by means of examples based on real data.

Abstract:
Megacities are characterized by a high level of energy consumption, a significant density of electrical loads and increased requirements for the reliability of power supply to consumers. Traditionally in the USSR and further in Russia, voltage classes of 6 and 10 kV are used for urban distribution electric networks. The increasing density of electric load and electricity consumption does not allow in extremely cramped conditions of developing cities to provide electricity through existing cable lines with a voltage of 6-10 kV due to their limited bandwidth and lack of reliability. The technical condition of the equipment and cable lines in the 6-10 kV supply networks has significant physical and moral deterioration. Existing networks have insufficient redundancy and have practically exhausted their ability to connect new consumers. These circumstances required a decision to switch to a voltage class of 20 kV, which is a strategic direction for the development of medium voltage electrical networks in Moscow. According to this decision, since the 2000s, electric networks with a voltage of 20 kV have been actively developing in Russia and in Moscow. This article analyzes the implemented approaches to the use of an electric network of 20 kV in megacities of different countries.

Abstract:
The electric grid system is the basis for functioning of the Unified electric power system of Russia and technologically isolated electric power systems. One of the most serious problems in the electric power industry is the aging of the fixed assets of already built and operating power grid facilities. The second problem is to clarify the seismic hazard of the territories of the Russian Federation in the direction of its growth. As a result, the number of power grid facilities fall into the zones of increased seismic hazard. In the zone of 7 points or more, approximately 30 % of the entire length of electric networks and transformer capacities are located. Information is provided about the characteristics of seismic load and how the objects respond to an earthquake. The experience of earthquakes testifies to the high vulnerability of the overhead power lines, cable power lines, substations, power transformers, relay protection equipment and automation under intense seismic loads. Information is provided about massive damage to the power grid during earthquakes in the territory of Russia, Armenia, and other countries of the world. Frequently occurring short circuits during earthquakes in electrical networks, at transformer substations, in electrical equipment elements of power grid facilities lead to fires. It is determined that power grid facilities have less seismic resistance than electric power generation facilities, than buildings and structures where electrical equipment is located. The problem of insufficiency of the current regulatory framework for ensuring seismic resistance of electric power facilities was also identified. Possible measures to prevent accident rate and increase the resistance, reliability, and seismic stability of power grid facilities in case of earthquakes are considered. The development of normative regulation will allow to take measures to ensure the seismic stability of power grid facilities in operation, and to ensure that control and supervision activities are carried out at a higher level.

Abstract:
Currently, the bulk of the information necessary for the implementation of supervisory control and the controllability of electrical equipment comes from telemechanics systems. A prerequisite for the construction of new electric power facilities or for the reconstruction of old ones is the introduction of telemechanics systems. Telemechanics systems are actively developing and improving. Initially, all of them consisted of a controlled telemechanics center that monitors and controls the system, receiving and processing analog signals from analog measuring transducers via numerous direct cable communication lines. The main disadvantages of such an organization of telemechanical systems include a large amount of connecting cables, scaling difficulties and low metrological characteristics. With the advent of digital transmitters, it became possible to transmit signals from them in digital form, which reduced the number of connecting lines and simplified the scaling and fault tolerance of systems. Now with the help of one measuring transducer it is possible to measure several parameters at once. The main measured parameters of power plants include: current strength, phase voltages, AC frequency, active, reactive and apparent power. This article describes the organization of the telemechanics and communication systems of the Astrakhan TPP-2. The analysis of the existing station power control algorithm is given. A variant of its modification is proposed. An example of the implementation of the proposed modification of the algorithm is described.

Abstract:
The issues of fundamental changes of electric power-supply of non-traction devices, such as, line-section devices and systems of railway transport are addressed in the article. It is clearly shown that the possibility of electric power-supply of such consumers without using the common high-voltage line-section power-supply lines of alternative voltage of 6 or 10 kV and respective power-supply substations can be implemented in practice. The essence of the proposed is that the electric power-supply source is not a high-voltage power-supply line, but a device which converts potential mechanical energy of a train, moving along a line section between signal points of railway automatic block system, into electrical one. Putting the described power-supply devices into operation provides technical as well as economic advantages over currently and widely used power-supply systems. The conversion of energy is carried out by changing magnetic resistance of a magnetic circuit, which includes railway car wheel-set in motion and direct neodymium magnet. Change in magnetic resistance due to the law of electromagnetic induction results in alternate voltage in the inductance coil, which is used as the electric power-supply source for non-traction line-section power consumers, including but not limited to, signal point of railway automatic block system. In case there is no wheel-set on the converter, electric power-supply for the power consumer is delivered by the electric energy accumulated in an ionistor (supercapacitor).

Abstract:
Python, which is widely used today, is one of the open-source programming languages. In the Python program, its interface is done through the PyQt5 library. With PyQt5, it is possible to develop object-based software that takes up less space on the disk and runs faster. In this study, an educational calculation and analysis program (ITUPSA) was designed for the Electric power systems course using the Python interface. Electric power systems are one of the fundamental courses in electrical engineering. This main course is taught in three sub-course groups as energy transmission-distribution, energy flow and energy economy. The energy transmission-distribution course package constitutes the first and most comprehensive part of the electric power systems group. In the energy transmission-distribution, the creation of the transmission line model and the calculation of the line parameters form an important part of the training. This section contains very detailed mathematical calculations and it is very important that students get the correct result as a result of these calculations. This can be possible with a lot of practice. The interface design was made by students and faculty to teach practical examples correctly. This developed (ITUPSA) python-based interface program is very suitable for calculation and analysis exercises in both undergraduate and graduate courses in the Electrical Engineering department. The purpose of this study is to create a python-based interface in order to solve the problems related to these lines, to make the types of short, medium and long power transmission lines correct and understandable. In the study, after selecting the type of energy transmission line and all parameters related to the line, the necessary mathematical analysis can be made and also the analysis results can be plotted. The analysis program is available in two languages, English and Turkish.

Abstract:
The thesis is devoted to the development of new algorithms for estimation of system frequency, power system phasors and transmission line fault location in the context of power system protection and control. A z-transform signal model combined with a nonlinear post-filtering scheme to estimate the operating frequency in a power system is first developed in the thesis. The signal model parameters are identified by an optimisation method in which the error between the model output and the actual signal that represents a voltage or current in the power system is minimised. The form and the structure of the signal model do not require iterations in the optimisation process for parameter identification. The system operating frequency is directly evaluated from the model parameters. Effects of noise and any frequency components other than the operating or supply-frequency on the accuracy are countered very effectively by applying a median post-filtering on the time series representing the frequency estimates derived from the model. Extensive simulation studies and comparisons with previously-published frequency estimation techniques confirm the high performance of the method developed in the thesis in terms of accuracy and time delay. With respect to power system phasor estimation, a method is developed based on waveform interpolation in the discrete time-domain to counter the spectral leakage errors arising in forming, by discrete Fourier transform (DFT), the supply frequency phasors representing power system voltages and currents when there are system frequency deviations from the nominal value. The interpolation scheme allows DFT evaluation to be performed with a time window length which is exactly equal to the fundamental period of the voltage or current waveform. Comparative studies presented in the thesis confirm the improvements achieved by the method proposed over other previouslypublished techniques in terms of accuracy and computing time. With the availability of accurate operating frequency and phasor estimates, an optimal fault location method based on multi-conductor distributedparameter line model is developed. The method is a general one which is applicable to any transmission line configurations, including multi-terminal lines. The fault location method is based on the minimisation of an objective function in which the fault distance is a variable. The objective function is formed from combining the phase-variable distributed-parameter equations of individual line sections from the fault point to the line terminals. The multivariable minimisation leads to high accuracy and robustness of the fault location algorithm in which any voltage/current measurement errors, including sampling time synchronisation errors, are represented in the estimation procedure as variables in addition to the fault distance. Extensive simulation studies are performed to verify that the method developed is highly accurate and robust. The thesis is supported by two international publications of which the candidate is a joint author.

Abstract:
Thesis (MTech (Electrical Engineering))--Cape Peninsula University of Technology, 2016.
Power grid and system protection advancement greatly depend on technological advances. Advent technologies like digital microprocessor type protective relays facilitate paradigm shifts, providing inimitable beneficial engineering adaptations. Phasor measuring technology provides one such technological advance. The onset and rapid development of the Phasor Measuring Unit (PMU) provides an excellent platform for phasor-based, power system engineering. Power transmission constitutes a critical section in the electric power system. The power system transmission lines are susceptible to faults which require instant isolation to establish and maintain consistent system stability. This research focuses on the study of transmission line protection based on P-Class synchrophasor measurements. The IEEE C37.238-2011 Precision Time Protocol (PTP) paradigm shift facilitates practical application of synchrophasors in protection schemes. Synchrophasor procession and accurate data alignment over wide areas support the hypothesis of a phasor-based transmission line differential protection. This research aims to directly implement P-Class synchrophasors in transmission line differential protection, employing synchrophasors to determine fault conditions and administer corresponding protective actions in wide area transmission lines. The research also aims to evaluate the operational characteristics of the synchrophasor-based transmission line differential protection scheme. The research deliverables include a laboratory scale Test-bench that implements the PMU-based transmission line differential protection scheme, and a differential protection utility software solution that follows guidelines specified by the C37.118-2011 standard for synchrophasors. The findings stand to evaluate performance of the PMU-based line differential protection scheme, verifying the protection model as an alternate, practical and feasible backup protection solution. The research deliverables include a synchrophasor-based current differential algorithm, software utility for implementing the PMU-based protection scheme and a Test-bench for concept and feasibility validation.

Abstract:
Thesis (DTech (Electrical Engineering))--Cape Peninsula University of Technology, 2016.
Geomagnetically induced currents (GIC) are currents induced in ground-based conductor networks in the Earth's surface. The GIC are driven by an electric eld induced by geomagnetic variations which are a result of time-varying magnetospheric-ionospheric currents during adverse space weather events. Several studies have shown that there is a likelihood of technological damage (the power grid) in the mid- and low-latitude regions that could be linked to GIC during some geomagnetic storms over the past solar cycles. The effects of GIC in the power system can range from temporary damage (e.g. protective relay tripping) to permanent damage (thermal transformer damage). Measurements of GIC in most substations are done on the neutral-to-ground connections of transformers using Hall-effect transducers. However, there is a need to understand the characteristics of GIC in the power lines connected to these transformers. Direct measurements of GIC in the power lines are not feasible due to the low frequencies of these currents which make current measurements using current transformers (CT) impractical. This thesis discusses two techniques that can be employed to enhance understanding GIC characteristics in mid-latitude regions. The techniques involve the measurement of GIC in a power line using differential magnetometer measurements and modelling GIC using the finite element method. Low frequency magnetometers are used to measure magnetic felds in the vicinity of the power lines and the GIC is inferred using the Biot-Savart law. A finite element model, using COMSOL-Multiphysics, is used to calculate GIC with the measured magnetic field and a realistic Earth conductivity profile as inputs. The finite element model is used for the computation of electric field associated with GIC modelling.

Abstract:
The US Navy has pursued gas turbine electric start systems since 2003. Such a system has been extensively tested at the Naval Surface Warfare Center, Carderock Division (NSWCCD) Land Based Engineering Site (LBES) in Philadelphia, PA. It was demonstrated on a General Electric (GE) LM2500 main propulsion engine as well as a Rolls Royce (RR) MT30 engine. Presently, the system is being refined and repackaged to undergo U.S. Navy qualification for production use. Given the performance success of electric start the next logical step is to extend its application to other engine lines such as the Ship Service Gas Turbine Generators (SSGTG). In order to facilitate platform integration, the electric start concept has been evolved into the Electric Start and Generation System (ESGS). As expected, this system has the ability to start a gas turbine by purely electrical means. Once the engine has reached idle speed or above, the ESGS becomes a generator capable of producing power. This power may be harnessed to address dark start capability on Surface Combatants. The ESGS configuration simplifies integration of bulk energy storage such as a flywheel device or battery pack. This will ensure availability to the engine under a loss of platform power scenario thus providing self-sustainability to all the gas turbine’s electrical functions. Another alternative is to continuously provide ESGS generated power back to the electrical grid in continuous support of the engine auxiliary systems. In this case, flywheels and batteries may be replaced by advanced transfer switches that redirect power where it is needed on demand. This paper describes a program undertaken by NSWCCD to carry out land based testing of an advanced design ESGS. An overview of system requirements is given from a perspective of platform integration. The system architecture is fully described. It is an evolution of ESGS technology that has been extensively tested on RR MT30 and GE LM2500 gas turbines at NSWCCD LBES. Compared with existing air and alternative hydraulic gas turbine starter systems, this system is more compact and provides the benefits of simplified platform integration. It incorporates energy storage to provide black start capability for the gas turbine. Battery and inertial energy storage technologies are discussed in detail for use with the ESGS.
