摘要
在m/n类型电气主接线中,通常认为双断路器接线可靠性最高,3/2线次之,4/3接线又次之.而通过对三峡电站的几个不同主接线方案进行可靠性计算机模拟却得出相反的结果,对于这个结果,本文采用解析方法分析其原因,并从理论上证实在一定条件下它是正确的.
On the reliability of the m/n type substation scheme, it is commonly considered that the double-circut breaker scheme is the best, the 3/2 scheme takes second place,and the 4/3 scheme comes next. But through the reliability computer simulation of several substation schemes of the Three-Gorge Power Plant, the opposite result was obtained. This paper analyses its reason using the analytic method and verifies theoretically that under a cerondition the above resrlt is correct,
