Abstract

Static var compensator (SVC) is an electrical device for providing fast reactive power on high voltage transmission networks. The primary purpose is usually for rapid control of voltage at weak points in a network. Static VAR Compensators are shunt connected Static generator/absorbers whose outputs are varied so as to control voltage profile of the electric power systems. A MatLab/PSAT model of the Nigerian 48-bus system with three phase fault, with and without SVC is also presented. The simulation results show that with SVC, voltage profile can be improved and power flow controlled in a Power System network.
