摘要

In this paper, the principle of Static Var Compensator (SVC) is analyzed in detail, and a kind of SVC system which consists of Thyristor Controlled Reactors (TCR) and Fixed Capacitor (FC) is designed. Bridge rectifier and L-R circuit is used to simulate the symmetrical three-phase load. Based on instantaneous reactive power theory, the SVC system signals are detected rapidly and precisely. In order to maintain the stability of the client node voltage and satisfy the requirements of system power factor, the voltage and admittance double loop control strategy is adopted, and the well-behaved steady-state effects is obtained. The break of node voltage caused by load disturbance or any other factors is restrained, and system power factor is well improved too. Finally, the SVC model is established under the environment of MATLAB simulation.The simulation results show that the proposed system can stabillize the fluctuation of power grid voltage and raise power factor, and the merits of fast response speed and high precision are verified.
