摘要
介绍了电压稳定评估中一种以灵敏度为基础判定独立系统中相关母线组的方法。该法将电网中具有相同V-Q特性曲线的母线合为母线组,在电压稳定分析中,只需分析重要的母线组及其无功储备源,大大提高了V-Q曲线法获取电压稳定裕度的效率。
The paper introduces a method judging coherent bus groups by novel sensitivity-based for voltage stability assessment.The method can combine some buses which have the same V-Q curves into a coherent bus group,and facilitate us to examine those concerned bus groups and their reactive reserve basin(RRB),in this way,it can greatly elevate the efficiency of V-Q curve method in obtaining the voltage stability margin.
