Modern power systems are complex and non-linear and their operating can vary
over a wide range. This paper presents a linear mathematical model of the
synchronous generator to control the excitation system based on Neural Network to
simulate an Automatic Voltage Regulator. The voltage regulator is used to modify
terminal voltage for the purpose of tracking a reference voltage and comparative with
PID controller. ANN (NARMA-L2) system is proposed as an effective controller
model to achieve the desired enhancement. This model after training can be called as
(Identifier).The proposed technique is evaluated on a single machine infinite bus
under different operating conditions (no-load and full load condition) by using
MATLAB simulink software.
