Introduction
 

In the excitation mode, no special exciter is set, but the excitation power is obtained from the generator itself and supplied to the generator itself for excitation after rectification, which is called self excitation static excitation. Self excited static excitation can be divided into self shunt excitation and self compound excitation. The self shunt excitation mode obtains the excitation current through the rectifier transformer connected to the generator outlet and supplies the generator excitation after rectification. This excitation mode has the advantages of simple structure, less equipment, less investment and less maintenance workload. In addition to the rectifier transformer, the self re excitation mode is also equipped with a high-power current transformer connected in series in the generator stator circuit. The function of this transformer is to provide large excitation current to the generator in case of short circuit, so as to make up for the shortage of rectifier transformer output. This excitation mode has two kinds of excitation power supplies, the voltage power supply obtained by rectifier transformer and the current source obtained by series transformer.
