Comparison of PV Supported DVR and DSTATCOM with Multiple Feeders in Stand Alone WECS by Mitigating Power Quality Problems
In this paper standalone WECS (Wind Energy Conversion System) is taken in which PV supported DVR (Dynamic Voltage Restorer) or D-STATCOM (Distribution Static Synchronous Compensation) is connected to mitigate power quality problems such as voltage sag, swell, unbalance and harmonics, which are created by both source and as well as due to other feeders disturbances. DFIG (Doubly Fed Induction Generator) is used as a generator to generate three phase supply from the wind source to the load. PV (Photo Voltaic) is used as a DC source for the VSI (Voltage Source Inverter). SRFT (Synchronous Reference Frame Theory) is used for the generating reference voltages. HC (Hysteresis controller) is used to generate pulse signal for the VSI of DVR or D-STATCOM. These voltages, when injected in line by a series or shunt transformer can regulate the voltage at the load terminals against any power quality problems. Thus the protection of the loads can be achieved economically using the DVR or D-STATCOM. Simulation results are carried out by MATLAB/Simulink to verify the performance of the proposed method.
