The 3BHE051476R3011 excitation control board usually has the following functions:
Excitation current control: Automatically adjust the magnitude and phase of the excitation current based on the operating status of the generator and the needs of the power grid, in order to maintain the terminal voltage and power factor of the generator within the set range.
Stability control: Monitor the operating status of the generator, suppress oscillations and instability by adjusting the excitation current, and ensure the stable operation of the generator.
Protection function: It has protection functions such as overcurrent, overvoltage, undervoltage, frequency deviation, etc. When abnormal conditions are detected, it can quickly cut off the excitation current to protect the generator and excitation system from damage.

This controller precisely controls the excitation current to adjust the voltage, reactive power, and other parameters of the generator or other excitation equipment. This helps to optimize the operational efficiency of the power system, reduce energy loss, monitor the real-time operation status of the power system, and adjust excitation parameters as needed to maintain system stability. When the power load changes or faults occur, it can respond quickly to prevent system instability or collapse. The controller has fault diagnosis function, can detect abnormal situations in the excitation system or related equipment, and take corresponding protective measures. This helps to reduce equipment damage and downtime, and improve the reliability of the power system.
