UN 0824A-P Var.1 Component unit
The automatic regulating excitation device is usually composed of measuring unit, synchronizing unit, amplifying unit, adjusting unit, stabilizing unit, limiting unit and some auxiliary units.
1. Measurement unit
The measured signal (such as voltage, current, etc.) is compared with the given value after being transformed by the measuring unit, and then the comparison result (deviation) is amplified by the pre-amplification unit and the power amplification unit, and used to control the conduction Angle of the thyristor, so as to achieve the purpose of regulating the generator excitation current.
2. Synchronization unit
The function of the synchronization unit is to synchronize the trigger pulse output of the phase shift part with the AC excitation power supply of the thyristor rectifier to ensure the correct trigger of the controlled silicon.
