A wind energy conversion system (WECS) with maximum power tracking (MPPT) using a SR machine operating as a generator is presented. MPPT of the wind turbine is achieved by sensing the wind speed and adjusting the wind turbine shaft speed for optimal tip speed ratio. MPPT using Hill Climbing Technique by perturbing the wind turbine shaft speed in the direction of increasing power is also implemented in the hardware setup. Outer speed loop using PI control generates the current reference used by the inner current loop. Hysteresis current control using softchopping is used to control the switched reluctance generator (SRG) phase currents. Initial excitation is provided by a low voltage battery and rated voltage is built-up by self-excitation. A chopper controlled dump resistor is used to maintain the output dc voltage at rated value. Power electronic circuit for the SRG is implemented in hardware using IGBT switches and DSP controller. Wind turbine is emulated using an induction motor and a vector controlled AC drive operating in torque control mode.

The main schemes presented are Voltage Oriented Control (VOC) and Direct Power Control (DPC). In VOC the decoupled Proportional Integral (PI) synchronous current controller is presented. For both VOC and DPC, line voltage sensor elimination techniques are presented using Power estimation and Virtual Flux estimation - Virtual Flux Oriented Control (VFOC) and Virtual Flux based Direct Power Control (VF-DPC). To overcome the variable switching frequency and high sampling frequency drawbacks of DPC, Virtual Flux based Direct Power Control with Space Vector Modulation (VF-DPC-SVM) is presented. The performance of VF-DPC-SVM is found to be comparable with VOC and VFOC.
