Abstract

Power Quality (PQ) is a phrase normally uses to describe all aspects of events in electrical system that deviates from normal system operations. Issues regarding PQ are growing concern especially towards power utilities. The increasing numbers of sophisticated electronics equipment like high efficiency variable speed drive (VSD) and power electronic appliances in the market producing harmonics current to the network system. Harmonics current can be transmitted from one facility through the others utilities equipment to neighbouring businesses through shared networks system. Harmonics current can cause harmful effects at the main equipment on network system and will cause problems such as overheated transformers, conductors, neutral wires, nuisance breaker trips, and voltage distortion all leading to equipment malfunction or fail which translates to loss of money to power utilities and consumers. The objective of this thesis model the nonlinear based on actual load to determine the level of harmonics produce by nonlinear loads. Other than that, objective of this thesis to investigate the current harmonics produce by residential and industrial load. The loads are connected to network system based on IEEE-13 bus distribution and small scale system to determine the current harmonics characteristic in network system for residential and industrial building.The main objective of this thesis to apply the mitigation technique to reduce current harmonics by using active and passive filter. Active filter will be using STATCOM as mitigation technique. The data will be tabulate for comparison and analysis. The results current harmonic level in network system will be reduce due to mitigation techniques apply in the system.
