abstract
Electrical Power Quality (PQ) is a crucial competitive and developing factor to all economic areas. The economic impact resulting from a bad PQ would be drastic to all consumers. Computers, uninterruptible and switched power supplies (UPS), and fluorescent lamps/tubes are examples of non-linear loads that have the consumption of a non-sinusoidal current, which cause disturbances in the power supply system (that may be sever or not). This paper discusses residential generic power circuitry analysis and simulation, under non-linear loads, in connection with undergraduate electrical engineering education. It briefly reviews some of the basic techniques, and presents a software tool that has been found very useful in the context. The tool has an easy-to-use, friendly interface, and can be used to teach design techniques or as a laboratory support to study the applicability of known methods to real situations. The students can perform simulations with their own data on Microsoft™ Windows® based platforms.
