变电所电气主接线可靠性分析

The Reliability Analysis of Main Electrical Connection in Transformer Substation

变电所电气主接线是实现电能传输和分配的一种电气接线,其根本任务就是尽可能经济而可靠地将电能提供给各种用户,因此往往将是否对用户停电作为一项主要的统计评价标准。本文采用基于元件状态空间的最小割集算法定量分析变电所电气主接线的可靠性,为主接线方案的合理选择提供了有效的评价依据。

The main electrical connection in transformer substation is one kind of electrical connections for transmission and distribution of electrical power. The fundamental task is to provide electrical energy to all kinds of users as economically and reliably as possible. So the electrical power failure to users is always considered to be a main statistical evaluation criterion. In this paper, the minimal cut-set algorithm based on components state space is adopted to quantitatively analyze the reliability of the main electrical connection, and the effective appraisal basis is provided for rational choice of the main connection schemes.
