The use of wind energy has become increasingly as a renewable energy source. The work is focused on finding the most efficient excitation angles and characterizing them for easy implementation under closed loop control. Through modelling of an experimental SRG and extensive simulation, it can be seen that the optimal-efficiency turn-off angles can be characterized as a function of power and speed level. Within the closed-loop power controller, the optimal efficiency turn-off angle is determined from an analytic curve fit using FEA. In this paper PI-CCC based SRG with fixed pitch angle for different wind speeds were modelled and simulated based on SIMULINK/SimPower Systems(PSB).
