摘　　要：电力系统的脆性源是电力系统脆性激发的源头,因此进行电力系统的脆性源辨识就是要找出电力系统的脆性源。本文基于直流潮流和分布因子法相结合,提出了快速找到系统脆性源的方法和步骤。通过对3节点电力系统脆性源的辨识,证明了此方法的有效性。Brittle source of electric power system is the element of rising brittleness motivated. Brittle source identification is the work of finding every brittle source. At first, build model of electric power system, based on direct current ride, all breach currents can be solved quickly. Break off every breach in turn. Use distributing factor method to obtain the other breach currents by breaking a breach current. If the other breach current exceeds the 20% rating current, then it breaks. This will lead to the refresh distribution, until all breach break, namely the brittleness being motivated, or until the other breach currents all satisfy the restriction condition. Thus all breach which lead brittleness to be motivated is the brittle source of electric power system. Through analyzing a three generatrixs system, obtain that (2),(3)and (4) is the brittle source.
