| Description: | or equivalent. Aims: To provide a detailed understanding of power system control, including stability control, frequency control and voltage control. Learning Outcomes: After successfully completing this unit students will be able to: explain power system steady-state stability, dynamic stability and transient stability on the basis of three operation modes of power systems; understand how to establish a power system model at steady-state operation mode; perform load flow calculation of the power system; apply Park's transformation; establish rotor movement equation of a synchronous generator; understand how to derive linearized Phillips-Heffron model and state space representation model of power systems; understand automatic voltage regulation of power systems and types of exciters; use algebraic method to design a Automatic Voltage Regulator (AVR); understand damping torque analysis for the study of power system oscillation stability; use phase compensation method to design a Power System Stabilizer (PSS); explain the conflict requirement of power system stability control and improvement of power system transient stability. Skills: Application of the information, techniques and methods detailed in the unit material, to the proposal of, and the carrying through of, appropriate solutions to engineering problems in the control of electrical power systems. Taught, facilitated and tested.
