摘　　要：实现了一个新颖的静止无功补偿器(SVC)静态模型并将其用于电压稳定分析.将SVC基频等值电抗及电纳表达为其控制角的显函数,推导了SVC线性化牛顿潮流方程;为了正确表达SVC的运行极限,引入一个增广的母线类型PQV.基于IEEE-300及IEEE-30母线系统,首先验证了模型的收敛性及求解效率,然后用最小奇异值及条件数指标分析了SVC对电力系统静态电压稳定性的影响.This paper prescribed a novel modeling of static var compensator （SVC） and its application in voltage stability analysis. Base frequency equivalent reactance and susceptance of SVC are expressed as an explicit function of its control angle and Newton-Raphson power flow equations are derived. In order to adequately represent the operating limit of SVC, an augmented bus type named as PQV is introduced. Based on IEEE-300 and IEEE-30 bus systems, the high efficiency and good robustness of the modeling are verified, and then the minimum singular and condition number index are used to evaluate the effect of SVC on the voltage stability of power system.
