Control Of The Double Switched Reluctance Variable Speed Wind Power Generators Parallel System

The developed parallel system of the double Switched Reluctance variable speed wind power generators was presented. The component parts, such as the structure of the generator, the rotor position detector and the main circuit topology of the exciting power converter, and the block diagram were described. The fixed angle pulse width modulation control strategy was adopted for the output power control. The control pattern for balancing the distribution of the loads in the two generators implemented by fuzzy logic algorithm was given. The deviation of the average DC output current and the variation from the deviation of the average DC output current were used as the input control parameters in the fuzzy logic controller, the increment of the duty ratio of the pulse width modulation signal was used as the output control parameter in the fuzzy logic controllers. The developed prototype was tested experimentally at three different loads with no-synchronization rotor speed in the two generators. The tested results show that the relative deviation of the output power in generator 1 & 2 is within +/- 10%.
