Self excited induction generator using a thyristor controlled reactor: Frequency regulation and reactive power compensation

This paper presents a loaded SEIG system controlled by a FC-TCR which consists of a big fixed capacitor in parallel with a thyristor controlled reactor in series with a fixed inductance. The output frequency is regulated thanks to the TCR branch by compensating either the excess or the lack of the reactive power system which depends on the load conditions and on the prime mover. This control method was preceded by a static steady method that have determined accurately the required excitation capacitor value for each desired load power. The control strategy is implemented using MATLAB/Simulink.
