Abstract :
The article is focused on a load angle estimation method in excitation regulation systems of synchronous generators. The estimation method is based on synchronous generator parameters given by the corresponding voltage-current vector diagram. The estimation results were compared with the measured ones. The estimation method gives satisfactory accuracy for load angles less than 120° el. Load angle regulation in excitation systems improves the stability of a synchronous generator in capacitive operating mode.
