Abstract

PURPOSE: To prevent abnormal control due to runaway on the automatic control side by providing two elements having excitation limiting function on the automatic control side and using one of these elements for trouble detection.
CONSTITUTION: Excitation limiters 9a and 9b are provided on the automatic control side, with the setting of the excitation limiter 9b provided slightly on the outer side of the setting of the excitation limiter 9a. At the time of the automatic control, with the reaching of the limit by the excitation state the excitation limiter 9a provides a limiting signal to an automatic voltage regulator 10. In this state, if the excitation state is going to get out of the excitation range due to a trouble on the automatic control side, the excitation limiter 9b provides a signal through a time limit element 9c to exclusion switches 11, whereby automatic control by the automatic voltage regulator 10 is switched over to manual control by a manual voltage setter 13.
