Research on Operational Status Monitoring Technology of the Secondary Circuit of Intelligent Substation Based on Virtual Circuit Visualization

Abstract

With the promotion and construction of intelligent substations, how to reliably monitor the operation status of the intelligent components and related circuits of the secondary circuit equipment has become a difficult problem to which needs to be paid attention in the optimization operation and relay protection of the power system. This article proposes an intelligent substation secondary circuit operation status monitoring technology, which visualizes the design of SCD files. At the same time, the entropy weight method and grey correlation analysis method are introduced into the monitoring system to improve the work efficiency of on-site operation and maintenance personnel and promote the development of substation intelligence.
