Technical Specifications 24VDC power supply, PT voltage and CT current input, analog excitation command output. Operating temperature: -40℃ ~ +70℃.
Functional Features Generator voltage closed-loop regulation, reactive power adjustment, over-excitation and under-excitation limiting, loss-of-field alarm, excitation fault diagnosis.
Application Scenarios Synchronous generator AVR control, grid-connected generator voltage stabilization, standby generator excitation control.
Performance Parameters Fast voltage regulation response, low steady-state voltage error, stable operation under reactive load fluctuation.
Structural Characteristics Heavy-duty rack pluggable module, excitation running and fault LED indicators.
Working Principle The module samples generator terminal voltage continuously. If actual voltage deviates from setpoint, it adjusts the excitation output command to change excitation current and keep generator voltage stable.
Installation Requirements CT and PT signal cables should be shielded, install surge suppression components for AC sampling loops.
Usage Notes Set excitation limit parameters before grid connection, avoid long-term over-excitation operation.
