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

Öz

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.

PC Laboratuvarların Aktif ve Bekleme Modunda Güç Tüketimlerinin İzlenmesi için Güç Kontrol Sistemi Tasarımı

Öz

Bu çalışmada, güç kontrol sistemi (GKS) tasarımı ile kullanıcının anlık olarak güç tüketimi konusunda bilgilendirilmesi ve cihazların bekleme konumunda enerjisinin kesilmesi yoluyla enerji tasarrufu sağlanması amaçlanmıştır. Yapılan çalışmada Amasya Üniversitesi Mühendislik Fakültesindeki Lab-1 ve Lab-2 de bulunan 39 adet PC’lerin güç tüketimleri tasarlanan sistem üzerinden incelenmiştir. Lab-1’de eski nesil bilgisayarlar bulunurken Lab-2’de yeni nesil bilgisayarlar yer almaktadır. Çalışma kapsamında yapılan test ve ölçümlerde kullanılan bilgisayarlar doğrudan priz yerine GKS üzerinden enerjilendirilmiştir. Bu yöntemle aktif çalışma ve standby çalışmadaki elektriksel güç tüketimlerinin belirlenmesi, elektrik tüketimlerinin yıllık olarak hesaplanması ve faturalara yansıması ortaya konulmaya çalışılmıştır. Deney yöntemi günlük bir bilgisayarın 2 saat aktif çalışma ve 23 saat standby konumda kalması üzerine belirlenmiştir. Sonuçlara göre GKS kullanımı ile yıllık bazda %56 kayıp standby gücün önüne geçilebileceği öngörülmüştür. Bu kayıp gücün yıllık fatura bedeli Lab-1 ve Lab-2 için sırasıyla 14.116,93 TL ve 8.470,12 TL olarak hesaplanmıştır. Yapılan çalışmanın, bu konuda çalışma yapan araştırmacılara önemli katkı sunacağı düşünülmektedir.
