This project work involves the investigation of power quality issues facing electric distribution utilities today. It contains research from various references to define power quality and summarize its effect on electric distribution utilities, end-user equipment manufacturers, and power consumers connected to the distribution system. The project also contains a power quality enhancement case study of an existing load site with a specific power quality concern. The case study includes a problem definition, an analytical summary of the situation, and a review of power quality enhancement solutions. The case study reviews and evaluates the effectiveness of several power quality enhancement solutions. A variety of zero sequence harmonic trap filters applied in different configurations are simulated in the analysis. The solutions are ranked on effectiveness to enhance power quality based on an analytical simulation using symmetrical component theory. The performance measured in the case study are neutral current reduction, neutral to ground voltage reduction, single line to ground fault current rise, and filter load duty. The solution performance measures are prioritized and the solution providing the best overall results is recommended. (Abstract shortened by UMI.).

Maintaining a stable level of power quality in the distribution network is a growing challenge due to increased use of power electronics converters in domestic, commercial and industrial sectors. Power quality deterioration is manifested in increased losses; poor utilization of distribution systems; mal-operation of sensitive equipment and disturbances to nearby consumers, protective devices, and communication systems. However, as the energy-saving benefits will result in increased AC power processed through power electronics converters, there is a compelling need for improved understanding of mitigation techniques for power quality problems. This timely book comprehensively identifies, classifies, analyses and quantifies all associated power quality problems, including the direct integration of renewable energy sources in the distribution system, and systematically delivers mitigation techniques to overcome these problems. Key features: • Emphasis on in-depth learning of the latest topics in power quality extensively illustrated with waveforms and phasor diagrams. • Essential theory supported by solved numerical examples, review questions, and unsolved numerical problems to reinforce understanding. • Companion website contains solutions to unsolved numerical problems, providing hands-on experience. Senior undergraduate and graduate electrical engineering students and instructors will find this an invaluable resource for education in the field of power quality.
