PV and Fuel Cell based Dynamic Voltage Restorer for LVRT Improvement of DFIGWTS

R. Shobana, Dr.K. Balachander, Dr.A. Amudha, Dr.G. Emayavaramban and M. Siva Ramkumar


The project proposes about the compensating fault ride-through (FRT) of a wind turbine based on doubly-fed induction generator (DFIG), voltage dip by using a PV supported dynamic voltage restorer (DVR). DVR a custom power device is used in series with grid by using coupling transformer. This device is used to protect the critical load in which the fault occurred due to source side disturbance. PV is used as a source to DVR and during fault PV supports DVR to clear the fault. With the proposed control method, the DVR can compensate for the FRT, while the DFIG wind turbine can continue its normal operation as demanded in actual grid codes.
