Abstract. The paper describes the structure of electrical power equipment digital twin proposed by the authors and consisting of 11 images (Virtual structure, Event registration, Visual, Technical and economic and a group of multiphysical images such as Physico-chemical, Electrophysical, Electromagnetic, Thermal, Electrodynamic, Mechanical, Acoustic. The composition and functions of examinations are given for each image of electric power equipment digital twin. The state and condition of the equipment during the examination are described. In addition to well-known examinations of online monitoring and offline diagnostics, the authors propose groups of examinations that allow to predict changes in the technical state of equipment using simulation modeling (mathematical, expert and statistical models) when operating conditions, characteristics of materials and external influences on equipment change. Examples of examinations of the digital twin of high-voltage power transformers are given.

Operation of a Deficit Power System: Lebanese Case

Ramzi El Dobeissy, Vanin A.S., Nasyrov R.R., Sharov Y.V. (NRU “MPEI”, Moscow)

 

Abstract. The main task of any power system is to ensure the demand for electricity from all consumers. The ability of the power system to provide power supply to consumers is characterized by its adequacy. In most countries, the acceptable adequacy level is between 3 and 35 deficit hours per year. At the same time, there are deficit power systems in which proper adequacy level is not provided. The paper analyses the operation of the electric power system in deficit mode. This problem is considered in the example of Lebanon, which has been in such mode for several decades. The paper describes the technical condition of the power system and climatic, geographical, and social conditions in which it operates. The analysis of the components of the power balance, namely generation, consumption, and energy losses, is performed. The annual load schedule is shown in a generalized form. Based on these data, the adequacy of the Lebanese power system is calculated. The current method of power supply is shown and analyzed. As an example, it shows a schedule for switching feeders on and off for one substation. It allows to limit the total power consumption and ensure a power balance in the switched-on part of the power system. At the end of the paper are perspective plans for the development of the Lebanese power system and ensure adequacy.
Keywords: adequacy, Lebanon, power shortage, electric power system

A New Concept for Building Distribution Networks for Power Supply to Remote Consumers

Soshinov A.G., Atrashenko O.S. (Kamyshin Institute of Technology (branch) of the Volgograd state technical university)

 

Abstract. The current schemes of low-voltage distribution networks for agricultural purposes today do not correspond to the modern regulatory and technical base, reduce the reliability of electricity supply, the quality of electricity, and increase its losses. An additional problem is the low level of automation of rural distribution networks and protection against unauthorized connections. According to NTD, one of the most promising and effective ways to solve the problems described in the article is the application of the new concept of building an electric network of 0.95 kV. Consumers located in the immediate vicinity of the TP are connected to the 0.4 kV network from the transformer winding 0.4 kV, and remote consumers to the 0.95 kV network through individual column transformers 0.95/0.4 kV or 0.55/0.23 kV. Using such a solution, it is expected to reduce technical losses of electricity by 5-10% or more and commercial by 30% of the actual value.
Keywords: distribution networks, agriculture voltage class, power losses, operation

Desynchronized-Doubly-Fed Synchronous Machines for Control a Flexible High- Voltage Interconnection

Suprunov I.S., Dvorkin D.V. (JSC “STC of UPS Power system development”), Novikov N.L. (PJSC FGC UES), Novikov A.N. (FBI “Energy-security”)

 

Abstract. This paper outlines a system for the vector control of the steady-state electrical regimes, transient processes, and active power- flow in a meshed and inhomogeneous power grid of up to 500 kV. The algorithm is to control a system of two desynchronized-doubly-fed synchronous machines injected in a high-voltage overhead transmission line. The complex system is supposed to qualitatively affect the parameters of steady-state modes and shirt-circuit-caused transient processes and to increase the transfer capacity of the grid. Wherein, this doubly-fed machine complex allows for a significant increase in the power quality and reliability within the grid’s normal operation. Long- term dynamic is considered. As a result, it is shown that the proposed system parametrization provides a significant decrease in active power fluctuations and power system swinging.
Keywords: transient process, inhomogeneous power grid, flexible power grid, desynchronized synchronous machines, power quality

Research of the Synchronous Generator Automatic Excitation Controller with Various Signals of Frequency Based Stabilization Channels

Klimova T.G., Nikolaeva O.O. (NRU “MPEI”, Moscow)

 

Abstract. In some cases, standard input signal to stabilization channels (the voltage frequency at the generator busbar) can significantly worsen the transients damping. The study on the AEC type AVR-3MT was carried out in a digital model of the power system using RTDS. The AEC operation was considered for several mode situations with different input signals of external stabilization channels. Their influence on the size and location of stability areas, the set of optimal parameters, and, as a result, on the quality of regulation is shown. At the same time, the use of other input signals in frequency makes it possible to obtain more effective transients damping than the use of a standard signal. For many situations, the calculated optimal parameters are outside the range of values implemented in the AVR MT, which makes it difficult to achieve the best quality of regulation. Thus, the necessity of analyzing AEC algorithms for different input signals of external stabilization channels is shown. Keywords: automatic excitation controller, evaluation of the transient quality, the input signals to the external stabilization channels

Method for Determining the Type of Damage in Electrical Distribution Networks of 6 kV Voltage Class

Mozohin A.E. (IDGC of Center — Kostromaenergo), Soldatov V.A. (Kostroma State Agricultural Academy)

 

Abstract. Before determining the location of damage in electrical networks, you first need to determine its type: short circuit, open circuit, short circuit with open circuit, etc. In this paper, it is proposed to use nine criteria to determine the type of emergency modes in 6 kV networks. The criteria are three groups: three ratios of phase voltages, three ratios of phase currents, and three ratios of phase voltages and the corresponding phase currents. Investigations were carried out both for metal closures and for short circuits through contact resistance. For each type of emergency mode, intervals were obtained within which the considered criteria change. This makes it possible to unambiguously determine the type of damage. In this case, if the short circuit occurred through the transition resistance, then its value is also indicated. The considered approach can be used in new devices for determining the location of damage in electrical distribution networks 6–10–35 kV.
Keywords: distribution electrical networks, a feeder of 6 kV, the emergency operation, criteria, a type of damage, metal short circuit, short circuit through transfer resistance
