<p>PURPOSE:To inhibit the sudden rise of output voltage from a brushless exciter on the fixing of voltage by bringing an input to a gate pulse generator to predetermined voltage on the fixing of voltage. CONSTITUTION:Field currents (IFEX) are adjusted by controlling a thyristor rectifier 7 at phase determined by a deviation between an output from a voltage setter 10 and real voltage on normal operation. On the other hand, IFEX are fed through an initial exciting circuit 6 from a battery 5 in a station on the fixing of voltage. The phase of gate pulses is brought to a fixed value simultaneously by a voltage setter 14 for fixing voltage. When voltage rises and reaches 70%-80% of rated voltage, a voltage detecting relay 13 is operated and the same control as normal operation is conducted.</p> |
