摘要
继电保护设备是一种重要的电力二次设备,继电保护装置分为继电保护装置本体和二次回路.文章通过对继电保护装置本体应用软/硬件失效模型进行风险评估,对二次回路应用故障树模型进行分析,建立了继电保护系统失效模型,该模型能够帮助电力自动化系统较准确地判断出系统的故障率和运行可靠性.
Relay protection equipment is the important equipment in the power secondary equipment. Relay protection device is divided into relay protection device boby and the secondary side. Based on the application of the device body protection software and hardware failure model for risk assessment and the analysis of the secondary side using fault tree model, the failure model of the relay protection system is built. The model can help electric power automation system more accurately judge the failure rate and the reliability of the system operation.
