A Novel Generator Side Converter Control Scheme of Direct Driven PMSG Wind Turbine

Abstract:

With the advance of electronic technology,the filed-oriented control of voltage space vector PWM have become more efficient in generator side converter control.This paper presented the direct driven wind turbine model and the permanent magnet synchronous generator (PMSG) model in synchronous rotating d-q reference frame.Using filed-oriented control of voltage space vector PWM in generator side converter control for enhance efficiency. The optimal control strategy can keep wind turbine working at optimal tip speed ratio for capture maximum wind power.A novel nonlinear PI controller for anti-windup implemented in control loop for highest efficiency of wind turbine which can be reached.Simulation results verified and shown via Matlab/Simulink that the performance of nonlinear PI controller for anti-windup in generator side converter control system is better than traditional PI controller in control loop for wind turbines.
