Are you sure you want to  Yes  No
• Your 'shunt active filter' , slide 12, is an interesting construction. Have you Muhammad built such filters? Is there any companies which manufacture them?

I also discussed about power quality ( http://www.slideshare.net/MAhonen/power-quality-and-health-is-there-a-connection-3605746 ) and my conclusions were a bit similar to yours.

Let's continue discussion.

Cheers

### Impact of the Extensive Usage of Energy Savers on Power Quality

1. 1. Impact of the Extensive Usage of Energy Savers on Power Quality By Muhammad Farrukh Yaqub University of Eng & Tech Lahore-Pakistan
2. 2. Presentation Layout Motivation.  Calculations  Circuit Diagram  Waveforms  Results  Conclusions 
3. 3. Motivation Rapid increase in the electric energy  demands.  Popularity of Energy Savers Lamps.  Encouragement from WAPDA.  Problems with Energy Savers.
4. 4. Encouragement from WAPDA (Taken from back side of Electricity Bills)
5. 5. Calculations Average Power: Only the fundamental component of current  contributes to the average power from the mains. i.e., Pav = Vrms I1rms Cos Ф1 THD  THD = [(Is/Is1)2-1]1/2 Power Factor  PF = Pav / Irms Vrms Current Distortion Factor  μ = Irms1/Irms Displacement Factor  DF = CosФ1
6. 6. Circuit Diagram
8. 8. Frequency Domain Analysis
9. 9. Practical Current Waveform
10. 10. Amplitudes for Different Harmonics
11. 11. Results from Calculations Average Power:  Pav = Vrms I1rms Cos Ф1 = 24W THD = [(Is/Is1)2-1]1/2 = 125.97 %  Power Factor  PF = Pav / Irms Vrms = 0.5733 Current Distortion Factor  μ = Irms1/Irms = .623 Displacement Factor  DF = CosФ1 = 0.92
12. 12. Suggestions 1. Using Active Filter: 2. Using Randomized Switching of the Bridge Rectifier.
13. 13. Conclusions High value of Total Harmonic Distortion and  poor Power Factor. It proves that the intensive use of energy savers  badly effects the power quality especially in winter season. The active filters should be added in the circuitry  of the energy savers lamps to obtain correction in the power factor and harmonics elimination.
14. 14. Thank you very much.
