Voltage Sag Compensation Using Dynamic Voltage Restorer for DFIG Fed Distribution Network
Abstract
This paper investigates compensation of voltage sag due to faults in distribution system for a doubly fed induction motor(DFIG) configuration using dynamic voltage restorer(DVR). Series compensation of terminal voltage during fault conditions using DVR is carried out by injecting voltage at the point of common coupling to the grid voltage to maintain constant DFIG stator voltage. However, the control of the DVR is crucial in order to improve the FRT capability in the DFIG-based wind turbines.wind turbine is controlled by pitch angle which controls the rotor and stator currents of induction generator under different wind speeds. DVR injects voltage in series using vector control which compensates voltage quality problems. The proposed work is verified using matlab/ Simulink software.
