【英文介绍】

The KUC755AE105 ABB excitation power unit provides excitation current to the synchronous generator rotor; The excitation regulator controls the output of the excitation power unit according to the input signal and the given regulation criteria. The automatic excitation regulator of excitation system plays an important role in improving the stability of parallel units of power system. In particular, the development of modern power systems leads to the trend of reducing the stability limit of units, and also promotes the continuous development of excitation technology. The excitation system of synchronous generator mainly consists of two parts: power unit and regulator (device). The generator excitation system is shown as follows:
