摘要
本文研究了电力供应系统地震功能失效评估方法,尤其对电力供应系统功能潮流分析方法与负荷的控制问题作了深入的探讨。不仅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,而且建立了电流控制模型,利用DSEA控制算法对供电系统进行负荷控制,并在此基础上进行了系统过负荷时的数值模拟研究;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理论基础。
In this paper, the seismic function failure analysis method of electric power supply system is introduced. Because the electrical power failure can be caused by disconnectivity and abnormal load flow in power transmission networks, the power electric flow is studied, and the system flow load control method is also discussed. Especially, the seismic sensitivity analysis model is studied and the decoupled security enhancement algorithm (DSEA) is employed to study the power flow control problems. Finally, an example is analyzed deeply. All of above will be a basis of seismic analysis, function assessment and damage mitigation for power supply system.
