| 中文摘要 | 本文以保护定值不合理导致的隐形故障为研究对象。首先采用沿线逐点故障计算的方法确定保护的隐患范围,接着用事件树分析和描述隐形故障的爆发条件,并用小概率阶数比较其概率的大小,然后以全网负荷裕度和断面可用传输容量的变化作为指标比较隐形故障的严重程度。最后给出了在某省级电网的应用算例。; Hidden failures due to irrational relay settings was studied in this thesis。Firstly,the point-by-point fault calculation along the line was taken to find the regions of vulnerability for hidden failures.Secondly,event tree was used to evaluate the probability for hidden failures being exposed,and probability order was taken as measures of probability. Thirdly,static load margin of power network and available transfer capability of sub-network were taken as index of severity for hidden failures.In the end,test examples in some provincial network were given。; supported by National Key Basic Research Special Fund of China(2004CB217904); National Science Foundation of China(50595414、50323002). |
