In power systems, it is very useful to regulate voltage at generator stations to keep terminal voltages within ±3% as the loads change. This thesis discusses a method to maintain the terminal voltages constant: a modern voltage regulator for a synchronous generator with a brushless excitation system. It also explores speed/frequency/power controls for a steam turbine-driven generator torque controller. The effects of varying voltage magnitude and angle on real power and reactive power and some aspects of the optimal dispatch are presented. A Computer-Aided-Design Program is used to simulate the performance of an excitation system and prime-mover governor with voltage regulation, which can quickly indicate the general nature of the control actions.
