The aim of this subject is to understand the fundamental concepts and basic theory involved in modelling and analysis of the various components that comprise power systems. Power systems involve the generation, conversion, transmission and distribution of electricity via the use of specific devices, such as transformers, generators and motors. It is expected that at the end of this subject the student will have developed a sound understanding of the functionality and characteristics in terms of physical concepts and mathematical models of each of the covered components and relate them to the real life operation of power systems, such as a country’s power grid or smaller power systems that connect to the grid.
The topics covered in this subject include: review of the basic theory of single-phase as well as three-phase circuits; calculations of power (real, reactive and complex); power transfer between buses (nodes), generators to loads; derivation of conditions for maximum power transfer; static stability limits; an introduction to protection and fault analysis; models for transmission and distribution power lines (overhead and cables); models for loads; basic models for power transformers, DC machines, the synchronous generator and the induction motor.
