Reliability Evaluation Method of Relay Protection Communication System Based on Markov Process
Relay protection communication systems are susceptible to refusal failure due to internal and external factors.The traditional assessment methods do not fully consider the dynamic behavior,fault propagation and complex environment,which leads to a high refusal failure rate in the assessment results.Therefore,the article proposes a reliability assessment method of relay protection communication system based on Markov process.The reliability of relay protection communication system is comprehensively assessed by selecting appropriate reliability assessment indexes to fully reflect the performance characteristics of the system,and utilizing the Markov process to construct the state random transfer probability matrix,which describes the transfer probability of the system in different states.The experimental results show that the method comprehensively considers a variety of factors,has a low refusal failure rate,and provides strong support for the safe and stable operation of the power system.
