Research on the switched reluctance wind generator system

The paper presents the Switched Reluctance variable speed wind generator sytsem for the application of wind energy The principles of the Switched Reluctance generator system are introduced. The mathematical models of the phase current, the average electromagnetic torque and the average electromagnetic power are given. The energy analysis of the generator system is also given. Two control strategies of the constant-power output control with the constant output voltage are advanced. The experimental tested results of the prototype with two control strategies of the constant-power output control with the constant output voltage are also presented. It is shown that the generator system at the wide wind velocity range has the high systematical efficiency and the low peak value of phase current with adopted the fixed conducting angle PWM control strategy. All those contribute to enhancing the reliability of the system, increasing the transformed ratio of wind energy/electrical energy, and reducing the cost of the wind generating electricity.
