  13. Benefits / Application • Enhance Power Quality • Reduce Energy Consumption • Improve Power Factor • Reduce THD • Clean Waveforms • Regulate Voltage • Reduce Light Flickering • Reduce GPR, neutral voltage/current René Rioux

  14. Strategies • Digital Simulation using SIMULINK, • MATALB software developer for model analysis and function constructor René Rioux

  15. Strategies 2 Phase 3 Wire Scott Connection Household Model René Rioux

  16. Digital Simulation • Green Plug Scheme 1, 2, and 3 • Balanced Case (4.5kW + 1.9kVAR) • Unbalanced 1 (Phase 1: 4.5kW + 1.9kVAR; Phase 2: 3.5kW + 1000VAR) • Unbalanced 2 (Phase 1: 4.5kW + 1.9kVAR; Phase 2: 5.5kW + 2.5VAR) • Non-Linear (Phase 1: 500W + 60VAR RECTIFIED; Phase 2: 2kW + 150VAR) • Fault Cases: One Phase Open Circuit; One Phase Short Circuit. René Rioux

  17. Digital Simulation • Approximate 9kVA loading @ 90%PF • Filters: • 150uF, 10mH, & 0.25 ohms René Rioux

  18. Digital Simulation • Green Plug Design 1 René Rioux

  19. Digital Simulation • Green Plug Design 2 René Rioux

  20. Digital Simulation • Green Plug Design 3 René Rioux

  21. Conclusion • Green Plug: • Raised PF by average 5% • Reduced Energy Consumption by an average 5% • Reduced Harmonics almost 50% on NL load • Fault Cases showed no sign of excess currents that would harm the filter • All controllers had similar controllability, the filters varied the performance • Seems they need to be “Taylor Made” René Rioux

  22. Conclusion • Neutral current control has limited capabilities which in turn showed limited portability • Green Plug design 2 performed the best René Rioux

  23. Future / Extended Work • Study on household: loading, THD... • Use maximum PF controller, or minimum power controller with Green Plug, which uses both phase current and voltage (more costly, and compare advantages) • Uses single phase filters on both phases • Transient Analysis on Green Plug / Household Model René Rioux

  24. Future / Extended Work • Build Prototype, Lab testing, & Field Testing René Rioux

  25. Questions René Rioux
