Power Control System Design for Monitoring Active and Standby Power Consumptions of PC Labs

Abstract

In this study, it was aimed to provide energy saving by informing the user about the power consumption instantly with the power control system (PCS) design and by cutting the energy of the devices in standby mode. The power consumptions of 39 PCs in Lab-1 and Lab-2 in Amasya University Engineering Faculty were examined through the designed system. Lab-1 contains older PCs while Lab-2 contains new generation PCs. The PCs used in the measurements made within the scope of the study were energized via PCS instead of a direct electrical socket. With this method, it has been tried to determine the electrical power consumptions in active work and standby work for calculate the annual electricity consumption and to reflect it on the invoices. The experimental method was carried out on the daily PC staying active for 2 hours and standby for 22 hours. According to the results, it is predicted that 56% lost standby power on an annual basis can be avoided with the use of PCS. The annual invoice cost of this lost power is calculated as 14.116,93 TL and 8.470,12 TL for Lab-1 and Lab-2 respectively. It is thought that the study will make an important contribution to researchers working on this subject.
