Abstract

Abstract: The high-voltage bus stability of power plants is critical to the stability of the power system. Attaching a power system voltage regulator (PSVR) to the control system can improve the effective dynamic reactive reserve capacity of the generators, and improve the stability of the high-voltage bus of the power plants. Based on the control principle and mathematical model of PSVR, this paper analyzes the current compensation effect of PSVR to compensate for a portion of the transformer impedance. Based on an actual application demonstration project of PSVR, a detailed simulation model of the PSVR research system is built based on the power systems computer aided design (PSCAD) to simulate various disturbances such as power grid accident, impact load, and reactive voltage fluctuation, and the role of PSVR in improving reactive power support of power system is examined and verified. The simulation results show that the PSVR can make full use of the potential reactive capacity of the generators, improve the reactive response speed of the generators, restore the transient voltage faster, and improve the supporting function to the high bus voltage stability of the power plant.

Key words: power system voltage regulator (PSVR), electromagnetic transient simulation, voltage stability, dynamic reactive support
