ABSTRACT:
An excitation control apparatus for synchronous machine which coincides voltage/frequency ratio of a synchronous machine with a limited value without setting gains of an automatic voltage regulator considering the harmony between the automatic voltage regulator and voltage/frequency ratio limiter by means of adding the integrated output of a value corresponding to the deference between the limited value and obtained voltage/frequency ratio of the synchronous machine to a desired control value of the synchronous machine by the automatic voltage regulator.
