Abstract

Abstract: Brief introduction of power system voltage regulator(PSVR) control theory, the quantitative method of continuation power flow analysis of improved PSVR on static voltage stability of Zhejiang power system, then the sudden increase of load method and trajectory sensitivity analysis method for quantitative analysis of improved PSVR on transient voltage stability of Zhejiang power grid. The calculation results show that, whether it is from the system static voltage stability and transient voltage stability of power system, the power system voltage regulators are conducive to system voltage stability.

Key words: power system voltage regulator (PSVR), transient voltage stability, static voltage stability
