Abstract

In the recent years there is growing concern for “Electric Power Quality” with the modern electronics equipments such as UPS, PC’s, variable speed drives and industrial programmable logic controllers are sensitive to the variation of the supply voltage. In particular, motor start applications draw large amount current at the time of starting and contribute to system degradation, particularly in very sensitive area. This switching transient problem was noticed in the 90Ton chiller system of university. Hence this needs modeling the chiller system components and simulating the processes of switching transient. The practical results were analyzed and compared simulation study for evaluating the quality of power in the system. Consequently, this paper investigates the coefficient of performance (COP) of chiller to verify the accuracy.
