随着电力需求的飞速增长,电力系统互联程度不断加强,电压稳定性问题日渐突出。静止无功补偿器(Static Var Compensator,SVC)能够提供无功补偿,以维持节点电压稳定,目前在电力系统中已有广泛应用。研究SVC装置选址问题,通过正规形分析,以非线性参与因子和二阶参与因子为依据,且以系统特征值为衡量指标,确定SVC的最佳选址,最后通过PSAT工具箱时域仿真分析安装SVC后对系统电压稳定性的影响,以验证SVC最佳选址的准确性。将所提方法应用于IEEE14系统以确
With the rapid growth of power demand, the degree of interconnection of power systems has been continuously strengthened, and the problem of voltage stability has become increasingly prominent. Static Var Compensator (SVC) can provide reactive power compensation in order to maintain the node voltage stability, which has been widely used in power system at present. SVM device location problem is studied. Based on the normal form analysis, nonlinear participation factor and second-order participation factor, the best SVC location is determined by the system eigenvalue. Finally, the PSAT toolbox time-domain simulation The effect of SVC installation on system voltage stability is analyzed to verify the accuracy of SVC location selection. The proposed method is applied to IEEE14 system to confirm
