Development of the Software Package of Diagnostics of the Centralized Relay Protection and Automation System

Abstract

One of the possible promising directions for the development of relay protection technologies today is the development of a digital centralized relay protection and automation system (RPA). Due to the current state of development of modern information technologies and the emergence of new international standards, IEC 61970 and IEC 61968, additional opportunities have appeared for solving the problems of automation and control of power facilities, creating a digital type substation. A digital substation is an electric grid with a monitoring, protection and control system, and is based on the transmission of information in a digital format. The aim of the article is to develop a software package designed to diagnose a centralized relay protection system, which is one of the main elements of such a system. The structure of the software package is developed in the article, the data of the diagnostic system for the centralized relay protection system are described and grouped, its configuration is presented, and the problems of relay protection configuration are considered. Recommendations are given on setting up the relay protection and automation functions based on the analysis of their operation with the help of algorithms for determining the location of damage and reference algorithms. The algorithm of the digital diagnostic system of the centralized relay protection system is described and the data flow diagram of the digital diagnostic system of the centralized relay protection system is described. Currently, the software package is undergoing a testing phase and is in trial operation.
