ROBUST CONTROL OF A VARIABLE-SPEED WIND TURBINE WITH VARIABLE PITCH CONTROL AND STRATEGY MPPT CONTROL BASED ON A PMSG

Abstract

In this paper, we present a performance study of a variable-speed wind turbine with variable pitch control and sensorless control strategy used MPPT based on a Permanent Magnet Synchronous Generator (PMSG). This paper first proposes the PITCH angle control which is the most common means for adjusting the aerodynamic torque of the wind turbine when wind speed is above rated speed, is applied. control strategy used Maximum Power Point Tracking (MPPT) below the rated speed, which corresponds to low and high wind speed, and the maximum energy can be captured from the wind. The control scheme is tested for three real profiles of wind speed and for two reference wind powers. The effectiveness of the proposed control strategy is evaluated by simulation results
