In addition to regulating the generator voltage, the VOLTAGE REGULATOR circuitry includes under-speed and sensing loss protection features. Excitation power is derived directly from the generator terminals.
Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the VOLTAGE REGULATOR.
In addition to being powered from the main stator, the VOLTAGE REGULATOR also derives a sample voltage from the output windings for voltage control purposes. In response to this sample voltage, the VOLTAGE REGULATOR controls the power fed to the exciter field, and hence the main field, to maintain the machine output voltage within the specified limits, compensating for load, speed, temperature and power factor of the generator.
