By comparing the generator voltage with the given voltage, the static excitation controller calculates the control voltage according to PID method, and converts the control voltage to the corresponding phase shift Angle to change the output voltage (rotor voltage) of the SCR rectifier bridge, so as to achieve the purpose of controlling the generator voltage.

Excitation controller is one of the core control equipment of water turbine generator set, the main role is to control the electromagnetic excitation system in the generator set, the specific functions are as follows:

Control the excitation current in the generator set to adjust the voltage and current output values of the generator.
By monitoring the size and direction of the excitation current in real time, it can be adjusted and controlled to keep the generator working stably.
According to the demand of the power grid load, the excitation regulator is controlled to adjust the size and direction of the excitation current to adjust the output voltage and current of the generator to meet the demand of the power grid.
If the generator has overvoltage, overcurrent and other faults, the excitation controller will immediately send out the corresponding signal to notify the monitoring system for processing.
