Technical Specifications 24VDC power supply, AC voltage and current transformer input, analog excitation command output. Operating temperature: -40℃ ~ +70℃.
Functional Features Generator voltage closed-loop regulation, reactive power control, power factor adjustment, over-excitation and under-excitation limiting, excitation fault diagnosis.
Application Scenarios Synchronous generator excitation regulation, grid-connected generator voltage control, standby generator set AVR control.
Performance Parameters Fast voltage regulation response, low voltage steady-state error, stable operation under reactive load fluctuation.
Structural Characteristics Heavy-duty rack pluggable module, excitation status and fault indicator lights.
Working Principle The module samples generator terminal voltage and stator current continuously. It compares the actual voltage with the set value, adjusts the excitation command in real time to change the excitation current, so as to keep generator terminal voltage stable.
Installation Requirements CT and PT signal wiring must use insulating shielded cables, install surge suppression components for AC sampling loops.
Usage Notes Set excitation limiting parameters before grid connection, avoid over-excitation operation which may cause rotor heating damage.
