摘要
Abstract
In order to improve stability of static voltage of the power system,it is proposed to combine static var compensator (SVC)with thyristor controlled series compensator (TCSC)in power system lines and use dynamic continuous trend method for calculating static voltage stability margin of the power system.Firstly,steady state model for SVC and TCSC is construc-ted,concepts of node parameter factor and branch parameter factor are introduced and modal analysis method is used to de-termine vulnerabilities of system busbar and branches.In addition,parallel SVC is adopted for reactive power compensation for weak spots of busbar,series TCSC is used for optimizing power distribution of weak lines and dynamic continuous trend method is applied to work out static voltage stability margin.IEEE-1 4 node system is used for simulating calculation,and static voltage stability margin values of device without flexible alternative current transmission system (FACTS),single in-stallation of SVC or TCSC,combined installation of SVC and TCSC are compared.Results indicate the proposed new meth-od is able to quickly and correctly improve static voltage stability of the power system.关键词
