<p>PURPOSE:To accelerate the output response of the terminal voltages of an exciter and a generator by providing a high voltage exciting power source and providing a field current limiter between a firing pulse controller and a thyristor amplifier output. CONSTITUTION:When an automatic voltage regulator 4 becomes magnetized output, a field voltage EfV of an AC exciter 10 is outputted considerably highly. Accordingly, the field current Efi rises at a rapid responsiveness. Thus, the output field voltage GfV of the exciter rapidly reaches the maximum voltage value. When the output field voltage GfV of the exciter reaches the prescribed value, a field current limiter 16 operates so that the field current Efi of the exciter 10 becomes constant at that time, and controls so that the field voltage EfV of the exciter 10 maintains the maximum value. In this manner, the response of the exciter can be improved without altering the time constant and the output field voltage of the AC exciter.</p> |
