一种电力通信传输网可靠性指数计算方法

A Method of Calculation Reliability Index in Grid Transmission Network

摘要: 为了量化评估电力通信传输网的可靠性，提出了一种电力通信传输网综合可靠性指数的计算方法，其主要思想是基于可维修网元的有效性指数，得到简单通信系统的可靠性指数，进一步推演到复杂的电力通信传输网的可靠性指数，该指数可直接反映网络集中型业务的年度故障时间期望值。本方法符合电力传输网的业务分布特点，适合通过计算机仿真和计算，可用于电力传输网的可靠性评估、比较和优化效果验证等。

Abstract: This paper proposes a new calculation method of transmission network reliability index, to estimate reliability of electrical transmission network. First of all, the reliability index of series-and-parallel system is calculated based on the effectiveness index of the maintainable network elements, and then the reliability index of the complex transmission network is calculated, which directly reflects the average annual fault time of centralized business. This approach is consistent with the transmission network, and the calculation is simple. Using this method, it is intuitive and quantifiable to verify the effectiveness of network optimization on improving network reliability.
