%0 Journal Article %T Voltage Stability Improvement using Static Var Compensator in Power Systems %A Mark Ndubuka NWOHU %J Leonardo Journal of Sciences %D 2009 %I AcademicDirect %X This paper investigates the effects of Static Var Compensator (SVC) on voltage stability of a power system. The functional structure for SVC built with a Thyristor Controlled Reactor (TCR) and its model are described. The model is based on representing the controller as variable impedance that changes with the firing angle of the TCR. A Power System Computer Aided Design /Electromagnetic Transients including DC (PSCAD/EMTDC) is used to carry out simulations of the system under study and detailed results are shown to access the performance of SVC on the voltage stability of the system. %K Thyristor %K Transmission %K Simulations %K Stability %K Voltage %U http://ljs.academicdirect.org/A14/167_172.htm
