Modeling and Simulation of Wind Turbine Driven Permanent Magnet Generator with New MPPT Algorithm

چکیده
This paper presents Maximum Power Point Control for variable speed wind turbine driven permanentmagnet generator. The wind turbine generator is operated such that the rotor speed varies according to wind speed to adjust the duty cycle of power converter and maximizes Wind Energy Conversion System (WECS) efficiency. The maximum power point for each speed value is traced using Maximum Power Point Tracking (MPPT) algorithm. The rotating speed of permanent-magnet generator should be adjusted in the real time to capture maximum wind power. The system includes the wind-turbine, permanent-magnet generator (PMG), three-phase rectifier, boost chopper, inverter and load. The control parameter is the duty cycle of the chopper. PMG is made to operate at variable speed to achieve good performance. The entire WECS model consists of wind turbine model, PMG model and power converters model. The MATLAB / SIMULINK are used for simulation and the results are compared with laboratory setup.
