Simulation of The Transient Response of Synchronous Machines

The overall accuracy of a system is primarily decided by how correctly the synchronous machines within the system are modelled. The use of a second order model of synchronous generator is usually assumed to be sufficient to simulate the machine response. Yet this is inadequate for transient study. A simulation model is set up to examine the response of the synchronous machine during transient state. The effects of using the PID controllers comprising a higher order model of a synchronous machine in the power system are investigated. The other factors such as using different types of turbines and various component parts within the power system are briefly discussed. With proper modelling of the synchronous machine in the power system, a better understanding of the machine response under sudden large disturbances during transient conditions can be achieved. Hence a better controller of the synchronous machine can be designed.
