18. PROJECT ANALYSIS & DESIGN

19. AREA OF FOCUS As a part of our project, we did a case study on Cochin Port Trust and found that the power factor was below 0.9. as per our calculation, at 0.85 pf , the total cost including penalty was Rs. 3,51,394.25 per month . It’s noticed that the total cost got reduced to Rs. 3,32,653.25 per month , after the installation of the capacitor bank that increased the PF to 0.94 . The cost of capacitor was found to be Rs.200/kVAR and the cost of capacitor installation could be replaced in a period of 1 year and 2 months.

22. TARIFF Cost of energy per unit=2.75Rs/kWh/month

24. Selection of capacitor for 0.85 pf PF old = 0.85 PF new = 0.94 M =0.367 kVAR cap =165.81kVAR Cost of capacitor= Rs 200 per kVAR Total cost of capacitor, kVARcap =165.81 kVAR * Rs 200 = Rs 33,162. Incentive = Rs 2008.00/month. The capacitor installation cost will be compensated in 33162/2008 =16.51 months =1 year & 2 months .

28. FUTURE SCOPE In our project, we have not considered harmonics. In future, we can improve the power factor by adding a reactor circuit with the capacitor bank to eliminate harmonics. As a result, especially the 3 rd harmonic component can be detected and suppressed and power factor in whole can be raised up to a value of 0.99.
