摘　　要：本文研究了电力系统的地震功能失效评估方法,尤其对电力系统功能潮流分析方法作了深入的探讨。本文不仅分析了电力设施在地震动作用下的连通性问题,而且也分析了供电系统的潮流(包括电压和功率)变化对供电系统的影响问题;另外,通过一实例分析,对本文的研究方法进行了验证,从而为供电系统抗震分析、功能评估及灾害预防提供了理论基础。In this paper, seismic function failure analysis method of electric power supply system is introduced, which study not only the electric equipment linked probability when an earthquake occurs, but also the power flow analysis. Because the electrical power failure can be caused by disconnection and abnormal load flow in a power transmission network, the seismic load flow analysis methods of power supply system are studied specially. All of above will be a basis in research of anti-earthquake analysis, function assessment and damage mitigation for electric power supply system.
