| Abstract |
This work presents a new thyristor control scheme to switch the excitation capacitors of a wind driven induction generator supplying an induction motor. The excitation capacitors are composed of three groups, the first one is a fixed capacitor bank giving the minimum required excitation and permanently connected to the lines. The second group is a starting capacitor bank used only at the moment of starting of the system. The third group consists of switched capacitors to supply the additional excitation required under any changes in the wind speed or motor load. The switching strategy depends only on the terminal voltage signal. The voltage amplitude to frequency ratio is employed to control the firing signals of thyristors which result in switching on or off the excitation capacitors. |
