Research in the application of ASVG in Jiangxi electric power system

Aiming at the defects of low voltage level and poor transient stability, the authors choose advanced static VAr generation (ASVG), one of the key devices in flexible alternating current transmission systems (FACTS), to study the effect of the application of FACTS on China´s Jiangxi electric power system. In this paper, the Power System Toolbox (POWERSYS) of MATLAB is used to construct an ASVG control system. With this system, the steady state operation of ASVG under balanced system voltage and the reactive power controller of ASVG is simulated. The User Program Interface of the Power System Application Software Package (PSASP/UPI) developed by EPRI of China is used to work out the user program of ASVG, and the result of its application in the Jiangxi electric power system is satisfactory.
