P-controller AVR
Excitation regulator ARV-P.
Description
The P-controller AVR unit is an excitation regulator that implements a proportional law of generator voltage control and provides stator current compounding. This type of regulator is usually used to control slow excitation systems (machine and high frequency).
The P-controller AVR unit can be used as an excitation regulator in the synchronous generator model with the control system shown in the diagram.
The mathematical model of P-controller AVR is shown in the diagram.
