Application of fuzzy reasoning based power filter and dynamic voltage regulator for single phase micro wind power generation systems

In this paper, a Dynamic Voltage Regulator/Switched Power Filter (DVR/SPF) is proposed to overcome both power quality and voltage stability problems for single phase micro wind power generation systems. Beside the DVR/SPF a novel tri-loop dynamic error driven control structure is also proposed to be used in the filter control process. The total dynamic error signal is then minimized by using a modified fuzzy logic controller (MFLC) to meet the criteria's required for high power quality stable frequency and voltage levels. The performance of the MFLC is verified by comparing the results obtained using classical proportional plus integral (PI) controller. The proposed DVR/SPF, dynamic three error driven loops, PI and MFLC are modeled and simulated in MATLAB/SIMULINK Simpower environment. The simulation results are evaluated for the performance verification of the proposed filter and controllers.
