Research on Maintenance Cycle of Relay Protection Device Based on Non-Homogeneous Poisson Process
The relay protection device is one of the important equipment to ensure safety in the power system, and it is one of the measures to ensure that the relay protection device can work in good condition when it is properly overhauled. Based on the model of exponential distribution of failure rate of non-homogeneous Poisson process and relay protection device, the optimal maintenance time considering the lowest reliability and maintenance cost was analyzed in this paper. Through the simulation software, according to the fault situation of a company's relay protection device, the analysis results show that for the exponential distribution of failure rate, its outage cost and running time do not affect the optimal maintenance time.
