Excitation controller is an important component in the power system, ABB-KUC711AE101-3BHB004661R0101 is mainly responsible for controlling the excitation system of the generator. The main function of the excitation system is to provide direct current to the excitation winding of the generator to establish and maintain the terminal voltage of the generator and regulate the output of reactive power.
The main functions of the excitation controller ABB-KUC711AE101-3BHB004661R0101 include:
Voltage and reactive power control: By adjusting the size of the excitation current, the excitation controller can control the generator terminal voltage and reactive power output, so as to maintain the stable operation of the power system.
Stability enhancement: The excitation controller can enhance the stability of the power system by quickly responding to changes in the system and providing the necessary excitation current.
Fault protection: In the event of a failure of the power system, the excitation controller can respond quickly to prevent damage to the generator by reducing or cutting off the excitation current.
Excitation controller is usually composed of control unit, power unit and measurement unit. The control unit is responsible for receiving the signal from the power system and calculating the required excitation current according to the preset control strategy. The power unit is responsible for providing the corresponding DC current to the excitation windings according to the calculation results of the control unit. The measuring unit is responsible for monitoring the operating status of the power system in real time and providing the necessary feedback signals for the control unit.
With the development of modern power electronic technology, the performance and function of excitation controller are also improving. For example, some advanced excitation controllers use digital control technology, ABB-KUC711AE101-3BHB004661R0101 has higher control accuracy and faster response speed. At the same time, some excitation controllers also integrate fault diagnosis and early warning functions, which can find and deal with potential faults in time, and improve the reliability of the power system.
