线路不同位置发生事故严重性的简易判断方法

A simple judging method of contingency severity in different positions of power lines

综合性能指标法是用于事故扫描的一种比较有效的方法,然而利用该方法每次得到的性能指标排序表只能利用一次,利用率不高。为此,通过对线路两端设定事故,将综合性能指标表进行重组,使其能重复利用,同时提出了利用改进后的综合性能指标表来判断线路不同位置发生事故严重性的方法。该方法简单、准确性较好,可以满足工程和科研上的需求。

Integrated performance index method is an effective way of contingency screening. However, the table of integrated performance indexes acquired through this method can only be used once. Consequently, the table of integrated performance indexes is reorganized by screening both ends of power lines so as to enable its repetitive utilization. The judging method of contingency severity in different positions of lines by reusing the table is also presented, which is simple, accurate and can meet the needs of projects and scientific research.
