Control for Grid Connected Small Wind Turbine System

This paper presents a control of a grid connected small wind turbine (SWT) system. The chosen SWT topology consists of a synchronous machine (SM) with excitation winding, a full power back to back converter and an output filter. The control system consists of the hill search type Maximum Power Point Tracking (MPPT) algorithm and the Voltage Oriented Control (VOC). The two control algorithms are interacting over the DC- voltage controller. The proposed control requires small number of measurements that can be reduced to the electrical subsystem of SWT.
