The working principle of excitation controller mainly involves the control of generator excitation system. ABB-KUC720AE01-3BHB003431R0101-3BHB000652R0101 The role of the excitation system is to provide direct current to the excitation windings of the generator, thereby establishing and maintaining the terminal voltage of the generator and regulating its reactive power output. The excitation controller is responsible for controlling the operation of the excitation system.

Specifically, the working principle of ABB-KUC720AE01-3BHB003431R0101-3BHB000652R0101 excitation controller can be divided into the following steps:

Signal detection: The excitation controller first detects the operating status of the generator through sensors and other devices, including terminal voltage, current, active power, reactive power and other parameters.

Signal processing: The detected signal is sent to the control unit of the excitation controller for processing. The control unit will analyze and calculate these signals according to the preset control strategy and algorithm, so as to determine the current required excitation current size and direction.

Generate control signal: According to the result of signal processing, the control unit will generate the corresponding control signal. This control signal is usually a voltage or current signal that indicates how the power unit regulates the excitation current.

Power amplification and output: After receiving the control signal, the power unit amplifies it to generate enough power to drive the excitation winding. In this way, the field winding will get the corresponding DC current, thus establishing the generator’s terminal voltage and regulating its reactive power output.

Feedback and regulation: During the operation of the excitation system, the excitation controller will constantly detect the operating state of the generator and fine-tune the excitation current according to the feedback signal to ensure that the generator is always running in the best state.

In addition, the excitation controller usually has some protection functions, such as over-current protection, over-voltage protection, under-voltage protection, etc., to ensure that when the power system fails, the excitation controller can respond quickly and take appropriate protective measures to prevent damage to the generator.

In general, the working principle of ABB-KUC720AE01-3BHB003431R0101-3BHB000652R0101 excitation controller is to achieve accurate control of the generator excitation system through detection, calculation, control, feedback and other steps, so as to maintain the stable operation of the power system and optimize its performance.
