摘要
Abstract
Compared with the traditional substation relay protection, the structure and content of relay protection system ones in digital substation have changed greatly in structure and content, and there is no standard model and method to evaluate their reliability. Based on the analysis of the formconstitution of digital substation relay protection systems, the information flow is divided into three kinds, which are time synchronization flow, SV flow and GOOSE flow, and their possible topology for each kind of flow is analyzed detailed.. Then it uses the minimal path sets algorithm to calculate the connected rate of three kinds of information flow, and uses series and parallel model to calculate the overall reliability of relay protection systems. At last the paper discusses the software realization of this modeling algorithm, and the example analysis shows that this modeling method provides effective means to evaluate the reliability of different schemes of relay protection systems.关键词
