Investigation of transient response of synchronous machine: article / Hazwani Arshad

This thesis presents the investigation on transient response and stability of higher orders model of synchronous machine in a typical power system by using the PID controller. The PID controller aims to improve the dynamic response as well as to reduce or eliminate the steady-state error in the machine. The other factors such as using different types of turbines and various component parts within the power system are briefly discussed. A transfer function simulation model is developed by using the MATLAB Simulink software. The fourth orders of synchronous machine model which connected to an infinite bus are implemented for better understanding of the machine response under sudden large disturbances during transient conditions. The model elements consist of Automatic Voltage Regulator (AVR), Automatic Generation Control (AGC), an excitation system and coupling coefficient. Several improvements on the simulation model are included. Simulation results are presented in order to get stable system of synchronous machine by using the designed controller.
