Abstract
Due to fuel crisis and increasing power demand, present days the power grid is interconnected with various renewable energy sources, among them wind energy is a vital and gifted source. DFIG is highly developed wind turbine generator due to their simplicity and low cost but the Power electronic convertors of DFIG are very sensitive to grid side faults. This article presents a new control approach with “Sen” Transformer (ST) for DFIG attached to grid at the time of faults. This ST is used to increase the voltage level of the stator to create the necessary magnetic field to maintain the rotor current under its transient rating. The Microcontroller Based Controlled Unit (MBCU) is monitors the voltage at grid and compensates the required voltage by changing proper taping of ST for continuous operation of DFIG. Simulation results disclose the rotor currents of DFIG stayed within acceptable range for Low Voltage Ride Through.
