摘要

针对单一主保护和主后备保护系统，基于状态维修环境，首次建立了详细的、考虑人为失误影响的保护系统可靠性模型。定义了相应的可靠性指标，并通过算例分析了人为失误对保护系统可靠性指标的影响。分析结果表明:人为失误对单一主保护和主后备保护系统的可靠性影响都较大，在正常运行及修理等过程中要尽量减少人为失误，提高人员可靠性和保护系统可靠性。在多重保护系统运行中，不仅要提高主保护的可靠性，也要提高后备保护的可靠性，并把防止误动作作为指导思想。

Abstract

In view of the single main protection and main and backup protection system， a protection system reliability model considering the impact of human error is firstly developed in detail， which is based on the condition-based maintenance environment. Corresponding reliability indices are defined， through an example the impact of human error on the protection system reliability is analyzed. The analysis results show that human error has a great impact on both single main protection and main and backup protection system， and human error must be reduced as possible during normal operation and maintenance process. The human reliability and protection system reliability must be improved. Not only reliability of main protection should be increased， but also reliability of backup protection in the multiple protection system，and preventing malfunction of protection system should be guideline.
