Excitation and governing control of a power generation based intelligent system

Abstract EN

Modern power systems are complex and non-linear and their operating conditions can vary over a wide range.

In this work, the power system (PS) transient terminal voltage and frequency stability enhancement have been well investigated and studied through the following efforts. •Enhancing the responses of the transient stability by adopting conventional PID controllers as an additional voltage controller with the Automatic Voltage Regulator (AVR) in the excitation system for terminal voltage, and in the governing system for frequency deviation response. •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).

This identifier follows the system behavior even in situation of high disturbances. There are enhancement progress in terminal voltage V t, and frequency deviation Δ ω through the investigation for the three cases (without controller, with PID controller, and with NN controller) for single machine infinite bus using MATLAB –Simulink software
