Analysis of harmonic mitigation methods for building wiring systems

There is a growing number of available harmonic mitigation methods. Selection of the best suited method for a particular case can be a complicated decision making process. The difficulty normally arises from not knowing how a particular technology and design will perform in a specific nonsinusoidal system. This paper looks at seven harmonic mitigation methods and compares their compensation characteristics as applied to building wiring systems. Both passive and active mitigation methods are considered for harmonics generated by single-phase equipment. The performance is studied through computer simulation with detailed source and associated rectifier load interfaces in the model.
