Modeling and Application of a D-STATCOM in Voltage Flicker Mitigation.

D-STATCOM is one of the equipments for voltage flicker mitigation in power systems. Voltage flicker, a phenomenon of annoying light intensity fluctuation is caused by Electric Arc Furnace (EAF). The D-STATCOM is a three phase and shunt connected power electronics based reactive power compensation equipment, which generates and /or absorbs the reactive power. A Distribution Static Synchronous Compensator (D-STATCOM) is used to regulate voltage on a 25- kV distribution network. The (D-STATCOM) protects distribution system from voltage flicker. Simulations are carried out using MATLAB/SIMULINK to illustrate the use of (D-STATCOM) in mitigating voltage flicker in a distribution system. [ABSTRACT FROM AUTHOR]
