摘　　要：20世纪90年代以来,各国先后发生了多次大规模的停电事故,包括国外美加大停电、国内华东电网事故等,都造成了非常严重的损失。大规模连锁停电事故是复杂电力网络的一个重要缺陷,它的预防以及应急处理将减少因为大停电造成的巨量负荷损失以及进一步的经济损失。通过对甘肃电网的拓扑信息的行整理和简化,其基础上建立一个针对连锁停电事故的电力网络拓扑模型,并分析其发生大规模连锁停电事故的可能性。实验结果表明,甘肃省电网存在发生大规模连锁停电事故的隐患。Since the 1990s, numerous large-scale blackouts have occurred successively in many countries, including the 8-14 black- out in USA and Canada, east China power grid accidents, which have brought very serious losses. Large-scale blackouts are an im- portant drawback in complex power grid. Its prevention and emergency treatment will reduce the huge amount of load loss and fur- ther economic damage caused by the large-scale blackout. Here the paper build a power grid model for cascading failures based on Gansu province＇s power grid topological information which will be preprocessed and simplified. This model is used to analysis the probability of large-scale blackout occurred in Gansu province power grid. The experimental results show that Gansu province power grid exist potential risk for large-scale blackout.
