Excitation control system refers to the system used to control the excitation current of a generator. The main function of the excitation control system is to adjust the output voltage and reactive power of the generator to meet the needs of the power system.

Excitation control system usually consists of excitation controller, excitation power unit and excitation transformer. The excitation controller is used to control the output current of the excitation power unit, the excitation power unit is used to convert the excitation current to direct current, and the excitation transformer is used to raise the output voltage of the excitation power unit to the excitation winding voltage of the generator.

The performance and reliability of excitation control system are very important for the stable operation of generator, so it is necessary to consider the quality, performance and reliability of excitation control system when designing and selecting.

Excitation control system is an important part of generator set, KUC755AE105 is composed of synchronous generator and its excitation system. The main function of excitation control system is to adjust the voltage and reactive power of generator to meet the needs of generator operation.

The excitation control system generally consists of two parts:

Excitation power unit: The KUC755AE105 provides DC excitation current to the excitation windings of the synchronous generator to establish a DC magnetic field.
Excitation control unit: this part includes excitation regulator, forced excitation, forced demagnetization and demagnetization, etc., which automatically adjusts the excitation current output of the power unit according to the operating state of the generator to meet the needs of the generator operation.
In addition, the excitation control system also includes a speed regulation system, which controls the speed (frequency) and active power of the prime mover (turbine) and generator. Speed control system and excitation system are the main control systems of generator set.
