АНАЛИЗ НЕПРАВИЛЬНОГО ФУНКЦИОНИРОВАНИЯ УСТРОЙСТВ РЗА ЕДИНОЙ ЭНЕРГЕТИЧЕСКОЙ СИСТЕМЫ РОССИИ

Abstract

In this article, the causes of improper functioning of relay protection automation devices of the unified energy system of the Russian Federation over the past 3 years are analyzed and the main solutions to these malfunctions are considered. In the current conditions of economic sanctions against the Russian Federation, a temporary shortage of some protection components appeared in the unified energy system of our country, which led to problems in the maintenance of energy systems. For a long period of time, the Russian industrial automation market has been converted to electronics from companies such as Siemens, Rockwell Automation (Allen Bradley) and Schneider Electric. At the moment, these companies have suspended their activities in the Russian Federation and refused to sell their software in our country. Unfortunately, just as the Russian Federation has created the EU's dependence on our oil and gas industry, so the EU, together with the United States, has created the Russian Federation's dependence on electrical equipment. One of the main problems in the Russian electric power networks is the low reliability of their operation. This is due to the fact that the reliability of overhead lines depends on a large number of different factors, such as extreme climatic loads, wear of supports and lines. Therefore, the efficiency of determining the type of emergency mode of the line and disconnecting or switching consumers to a backup line allows you to increase the reliability of the power supply system by reducing downtime. The electric power system is characterized by normal, emergency, post-emergency and repair modes of operation. The main reason for the transition of the power system from a normal (repair) state to an emergency is a short circuit (short circuit).
