Course Objectives:
The class develops a tool for analyzing the complex and intricate electric power system, which forms the backbone of a society’s well being as well as its ability to function orderly and efficiently. With this tool, various major components in an electric power system are analyzed from generation to transmission to distribution to utilization. This analysis will cover transmission lines, machines, loads of various kinds and networks. System stability and control will also be examined. The economic operation of the system is further scrutinized for efficient and optimum operation.
Course Outcomes:
