ABSTRACT
The objective of voltage control is to have the root mean square (RMS) value of the terminal voltage of a generator (Va) tracking a reference. In the generator voltage control design presented in Bergen and Vittal, the modeling stops at the stage when the dynamics include both swing equation and rotor flux decay. In this chapter, the design also stops after including swing dynamics and rotor flux decay dynamics. It presents the simplest plant models represented by gains only. The chapter helps the reader to make a decision whether negative or positive feedback control should be adopted. It also presents the plant models with rotor flux dynamics only. Electromechanical dynamics represented by swing equations are ignored. The chapter examines voltage control design based on the presented plant models. It illustrates control design when both rotor flux dynamics and electromechanical dynamics are considered.
