What is the role of generator excitation system?

The power supply of the synchronous generator excitation current and its affiliates are collectively referred to as exciting systems. It is generally composed of two main parts of the excitation power unit and the excitation regulator. The excitation power unit provides excitation current to the synchronous generator rotor; the excitation regulator controls the output of the excitation power unit based on the input signal and the given adjustment criterion. The automatic excitation regulator of the excitation system has a considerable role in improving the stability of the power system parallel. The following diesel generator manufacturers take you with the main role of the excitation system of the generator.
A: The main role of excitation systems in the generator is:
First, according to the change in the load of the generator itself, the corresponding adjustment current is adjusted, and the voltage is maintained as a normal stable voltage.
Second, control the voltage allocation between the generators to ensure that there is no untenitting ZUI in the generator.
B: An electrical regulating device for controlling and regulating the active and adjustment of the excitation current in the excitation power source in the excitation power source is referred to as a exciting device. The exciting system is an indispensable part of the power station device. The classification of the excitation system mainly includes exciting power and exciting devices, wherein the main body of the exciting power supply is a exciting machine or a exciting transformer; in addition to maintaining synchronization with the motor, the exciting system also affects the reactive power value output or absorbed by the generator. When the excitation current suddenly increases, there will be a lot of problems. For example, the no power output will suddenly increase, which makes the voltage change tall. A series of problems will occur when the excitation current is hit. It is also possible to lead to the occurrence of different steps of power systems and generators. Excitation control is a system that protects the generator, ensuring the normal stability of the generator.
