<p>PURPOSE:To prevent an unevenness of output by automatic alteration and adjustment of the gain according to the state of the output. CONSTITUTION:A stabilization signal a detected wit a detector 1 is applied to an automatic voltage adjustor via a signal resetting circuit composed of an incomplete differentiation circuit, a phase compensating circuit 3, an amplification circuit 6 and a limiter circuit 5. A comparator 7 detects whether the output 6b of the amplification circuit 6 exceeds the set value. An integration circuit 8 integrates the output of the comparator 7 and provides an output 8b to change a gain of the amplification circuit 6. The adjustment of the gain of the amplification circuit according to the output prevents the output of the system stabilization apparatus from being uneven in one direction otherwise causing deviation of the terminal voltage of a synchronous machine from a set value by an automatic voltage adjustor for a long time.</p> |
