摘　　要：继电保护装置是电力系统中保障安全的重要设备之一。正确检修是保障继电保护装置正常工作的措施之一。针对传统检修存在人力、财力浪费等缺点,采用非齐次泊松过程与继电保护装置的失效率模型,分析考虑可靠度与检修成本的最佳检修时间。并根据某公司继电保护装置的故障情况,利用仿真软件进行了仿真验证。分析仿真结果表明:呈指数分布的失效率,其停用成本以及投入运行时间均不影响最佳检修时间。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 nonhomogeneous 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.
