中文摘要: 针对电力系统可靠性研究工作主要集中于一次设备,而二次系统可靠性研究相对较少的现状,提出了一种定量计算继电保护系统静态可靠性的方法.首先根据继电保护系统的物理结构特点抽象出其网络模型;然后,分别计算节点和支路的可靠性;最后,根据系统的网络拓扑结构计算得到整个系统正常工作的概率.将算例结果与实际运行统计数据进行对比,验证了该方法的合理性.
Abstract:A technique to quantitatively calculate the reliability of relay protection system is proposed.The network model is used to calculate the normal working probability of relay protection system which takes communication links of the secondary system of the intelligent substation as its branch routine and the intelligent devices such as protection,network switches as its nodes.The reliability of branch and nodes can be calculated by analytic hierarchy process.Then the reliability of relay protection system can be calculated according to the network topology.The comparison between the results of the examples and the actual operation shows that the method is reasonable.
