Modeling and simulation of permanent magnet synchronous generator wind power generation system using boost converter circuit

This paper proposes variable-speed wind generator system using the Boost chopper system. The boost chopper system has three speed control modes for the wind velocity. The control mode of low wind velocity regulates armature current of the generator with the boost chopper circuit to control the speed of wind turbine. The control mode of middle wind velocity regulates the DC link voltage with vector controlled inverter to control the speed of wind turbine. The control mode of high wind velocity regulates the pitch angle of the wind turbine with the pitch angle control system to control the speed of wind turbine. The hybrid of three control modes extends the variable-speed range. The boost chopper system simplifies the maintenance and improves the reliability and reduces the cost in compare with PWM converter system. extensive.
