Abstract
The mass penetration of both energy-efficient and consumer electronics into residential houses is introducing a totally new harmonic situation in today's distribution systems and complicating the mitigation solutions. In order to study the collective effect of today's distributed harmonic sources, this thesis developed an harmonic load model for residential service transformers and a detailed multi-grounded system model to conduct a system-wide harmonic study. The simulation results are consistent with the field measurements. The evolution of the resultant impacts over the next several years, as affected by the market trends of home appliances, is also determined. Mitigation studies were done from two perspectives. One is the system modifications. Various sensitivity studies were performed and analyzed to clarify which factors are important in terms of harmonic mitigation. Another mitigation study involved a zero sequence filter, whose fundamental theory was studied and effectiveness was tested and verified in simulations.
