【 摘 要 】

Power system voltage regulator (PSVR) is a kind of high-voltage side bus voltage control method, which maintains the high-voltage side bus voltage of the power plant at a high level, increases the reactive power limit of the generator, and improves the voltage stability of the power system. In this paper, a PSVR model with gain reduction is introduced. With PCS- 9410 excitation regulator, the semi-physical simulation system is constituted on RTDS. By setting a three-phase ground short-circuit on the high-voltage side transmission line, the time domain dynamic response of automatic voltage regulator (AVR) and PSVR is compared and analyzed in synchronous generator and synchronous condenser mode respectively, simulation results show that PSVR with gain reduction can increase the reactive power response speed of the excitation system in two modes.
