<p><P>PROBLEM TO BE SOLVED: To provide an excitation device of a synchronous machine that can continuously be operated without tripping the synchronous machine even if troubles occur in a plurality of parallel circuits of rectifying parallel circuits of semiconductor rectifiers that are constituted in multiple parallel rows, and also can be operated with improved excess stability. <P>SOLUTION: A limit current command circuit arranged at an AVR inputs a plurality of parallel fuse blowout signals, and controls an output of the rectifier so that the rectifier outputs a fuse blowout limit current value that is set so as to correspond to an excitation amount command value at the blowout of a plurality of parallel fuses. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
