A wind turbine simulation system based on switched reluctance motor

A simulation error model is defined to evaluate the goodness of WTS (wind turbine simulator) implemented by controlling the motor speeds. Error comparison is made between the Euler method and forth order Runge-Kutta method under different time steps and rotational speeds. MATLAB calculation indicates that the high-order numerical method can improve the accuracy of WTS. SRD (Switched Reluctance Drive) is adopted to track the reference rotational speeds in closed-loop speed control. The tracking system is set to typical II system to determine the simulation step. The experimental results indicate that the WTS can perform the wind turbine characteristic under constant wind velocity with variable load. In the MPPT test, the WTS characteristic also has a good identity with the simulated wind turbine.
