Study of Static Var Compensator Control Modes to Maintain Constant Active Power of Electric Arc Furnace

Abstract

The paper deals with the main result of development new static var compensator (SVC) control mode to maintain constant active power of electric arc furnace (EAF). The advanced SVC control system includes the active power feedback channel and limiting systems of phasor power factor and voltage, which hold back these parameters in maximum permissible values. EAF power-off time periods have been taking into account in the advanced control system. Features of SVC functioning in new mode are investigated by means the simulation model of electrotechnical complex "EAF-SVC" developed in the Matlab's Simulink application. During the experiment the diagrams of electrical parameters of complex "EAF-SVC" when SVC worked in new control mode were built. Conclusions and future research directions are determined.
