Computer simulation of electric power system

Describes how to use computer simulation as a useful tool for teaching power flow analysis at the undergraduate level. A PC-based computer program, which runs under the Windows environment, has been developed at Purdue University Calumet. It provides a user-friendly environment that allows the students to simulate and analyze events that occur on a transmission system. These events consist of changing the bus voltages at the generating stations, taking generating stations off-line and taking transmission lines out of service. After each event, the software calculates the voltage at each bus, and the real and reactive power flow through the system. The user can then analyze the change in these values because of the event. The software package is used as a supplement to an undergraduate course in electrical power systems. This has increased students´ ability to understand the way a power system responds to various loads and generation schedules. Examples of simulations are included
