Magnetic system refers to the supply of synchronous generator excitation current power supply and its auxiliary equipment collectively referred to as the excitation system, which is generally composed of two main parts of the excitation power unit and the excitation regulator

The excitation power unit provides the excitation current to the synchronous generator rotor, while 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
