REVIEW OF EXISTING TELEMECHANICS SYSTEMS OF HIGH-VOLTAGE SUBSTATIONS 35–110 KV OF GRID ORGANIZATIONS OF THE LPR AND DPR

In recent decades, telemechanical systems have been increasingly used in the energy sector, industry, transport, utilities and a number of other areas of the national economy of our country. In the electric power industry, telemechanics is used to provide operational dispatch control and control over the operation of power plants and substations that are part of energy systems. In electrical distribution networks, telemechanics is also used as an essential part of operational dispatch control and monitoring systems for substations of the highest voltage class of 35–110 kV. Telemechanics tools solve two main tasks: the transmission of technological information and the transmission of command information. Despite the current level of distribution of telemechanical systems in 110, 35, 10, and 6 kV electrical distribution networks, these systems have two main problems: initially limited functionality and wear and tear of existing telemechanics devices, which do not fully organize all modern functions of telecontrol, telecognalization, telecommutation, and teleconregulation; almost complete absence of telemechanical systems in distribution networks of 6–10 kV. To further find ways to solve these problems, it is first necessary to review the existing telemechanical systems in 110, 35, 10, and 6 kV electrical distribution networks. This is done in this work using the example of substations of the highest voltage class 35–110 kV of the network organizations of the LPR and the DPR. In the course of the research, based on the theories of automatic control systems, information measurement and control systems, the dynamics of discrete control systems using fuzzy logic is analyzed. The provisions of the theory of human interaction with an automated system, the elements of the "man –machine" dialogue are also used.
