Task Il: You were assigned to a team conducting an energy audit in hotel facility. After several site visits, you collected daily measurements of the peak power during peak hours and the average power factor during June and produced the following graphs. The monthly average peak power during peak hours was calculated and found to be 534.5 kW. The monthly average power factor

Question
Task II: You were assigned to a team conducting an energy audit in hotel facility. After several site visits, you collected daily measurements of the peak power during peak hours and the average power factor during June and produced the following graphs. The monthly average peak power during peak hours was calculated and found to be 534.5 kW. The monthly average power factor was calculated and found to be 85.3%. You were asked to work on the data to identify potential saving opportunities. One of them, was to limit the peak power to 200 kW during the peak hours in this facility for the entire month, the other was to improve the power factor to 93%. Peak power during peak hours Vs days 1070 970 870 770 670 570 470 370 270 170 70 10 15 20 25 30 35 Peak power during peak hours Vs days 95 90 85 80 75 70 10 15 20 25 30 35 Write a short note (to be incorporated in the audit report which your team leader will compile) which should include: 1. An estimate the savings resulting from both measures. 2. The sizing of the required power factor correction unit, taking into consideration that the average power is 750 kW. 3. Discussion of power quality aspects that need to be considered before installing the power factor correction unit.
