SVC Subsection Control Strategy Considering Voltage Stability of Dynamic Load

Abstract

A kind of Static Var Compensator(SVC) subsection control strategy for transient process of dynamic load is presented in this paper. The strategy can determine SVC's action according to the condition of system and load so as to output different compensation capacity in different stage to make dynamic load stable and make sure the voltage is qualified; SVC will be shut when it's noneffective in this strategy so that other regulate way can be used timely. The validity and accuracy of the strategy is verified in tow-bus equivalent system.
