发电厂变电站电气主接线的可靠性分析

Reliability Evaluation of Bus Configurations of Power Station and Substation

发电厂、变电站电气主接线可靠性的定量分析是电力系统可靠性研究的一个重要领域。本文将元件的故障以主动故障和被动故障分开考虑,建立了四状态元件模型,使用最小割集法量化了三种电气主接线的可靠性与经济性指标,可以直观地分析其可靠性水平,与经济性相结合综合选择最优的主接线方案。

Quantitative analysis of reliability of bus configurations of power station and substation is an important field of reliability research in power system. Considering active failure and passive failure of components, it is established four - state models of components and assessed reliability and economic indices of three different bus configurations using minimal cut - set method in the paper. It is an effective tool in seleeting optimal program of bus configuration, by comparing and analysizing intuitively their levels of reliability combi- ning economic indices.
