Research on Effects of STATCOM on Voltage in Wind Farm Based on PSASP

Abstract

Recently, the static synchronous compensator (STATCOM) device has been installed in Jiuquan wind farm in Gansu Province. To study its ability to support voltage, this paper presents a study of the mathematical model of the steady state and transient state of STATCOM and then uses the power system analysis software package (PSASP) to establish a user-defined model of STATCOM. In addition, the model is added into the power system example (CEPRI 7). After that, the power flow calculation and transient stability calculation are carried out to simulate and analyze. At last the STATCOM device is field tested in Jiuquan wind power base. Test results verify that STATCOM effectively supports the grid voltage.
