Household Green Plug for Energy Efficiency and Power Quality Enhancement

The Green Plug, part of the Energy Misers family, is a Modulated/Switched Dynamic Filter/Compensator designed by René Rioux and Dr. A. M. Sharaf. It improves power factor, quality, and reduces harmonics in residential loads, saving electrical energy consumption. This project involves modeling, designing, and testing the Green Plug for household energy optimization.

  1. Household Green Plug Presented by: René Rioux Advisor: Dr. A. M. Sharaf November 30, 2004

  2. Summary • Description/Background • Methodology • Work Completed • Work Remaining René Rioux

  3. Description of Green Plug “GREEN POWER” GP: Modulated/Switched Dynamic Filter/Compensator (MSDFC) for Electrical Energy Efficiency/Savings and Power Quality Enhancement delivered to a home The Green Plug is is a member of a family of Energy Misers/Economizers and Capacitor Compensator developed by Dr. A.M. Sharaf René Rioux

  4. Background • The filter uses work done by Pierre Kreidi, MScEE, and Dr. Sharaf for modeling of nonlinear loads and switching circuits • Can be used to improve Power Factor, Power Quality, Reduce Harmonics of Residential, Commercial Loads • Can reduce Electrical Energy Consumption KWh, for cyclical Inrush type loads René Rioux

  5. Methodology • Two phase three wire, 2Φ-3W • Modeling a house on Simulink/Matlab from a perspective point of view of the transformer René Rioux

  6. Methodology Equivalent Circuit René Rioux
