Abstract

Orta gerilim (OG) güç sistemleri elektrik enerjisinin son kullanıcıya güvenli ve sürekli şekilde temini için önemli role sahiptir. Bu bileşenlerde meydana gelen arızalar kısa veya uzun süreli enerji kesintilerine ve yüksek maliyetli kayıplara yol açmaktadır. Kestirimci bakım çalışmaları, arıza meydana gelmeden önce arıza belirtilerinin tespit edilmesini ve önlem alınmasını sağlaması sebebiyle güç sistemlerinde giderek daha fazla tercih edilmektedir. Bu çalışmada, arıza kök nedenlerinden biri olan kısmi deşarj olaylarının erken tespit edilmesi amacıyla orta gerilim güç sistemindeki uygulamaları özetlenmektedir. Bu doğrultuda, öncelikle kısmi deşarj olaylarının oluşum süreçleri açıklanmaktadır. Ardından, kısmi deşarj ölçüm yöntemleri güç sistemi bileşenlerine yönelik uygulama örnekleri ile açıklanmış ve bakım yönetimi süreçlerindeki önemi vurgulanmıştır. Elde edilen sonuçlar, orta gerilim şebeke bileşenlerindeki kısmi deşarj oluşumuna yönelik işaretlerin kestirimci bakım kapsamında izlenmesi sayesinde arızaların erken tespitinin ve yüksek maliyetli arızaların önüne geçilebilmesinin mümkün olduğunu göstermektedir.

Investigation of Partial Discharge Monitoring Techniques for Maintenance Management in Medium Voltage Power Systems

Abstract

Medium voltage (MV) power system has great importance to provide electrical energy to the consumers safely and continuously. Various types of faults in power systems components cause shortages and costly losses. Predictive maintenance studies are increasingly preferred in power systems because it provides to detect the fault symptoms and to take action before a malfunction occur. In this study, measurement methods of partial discharge (PD) activities, which are one of the root causes of faults in medium voltage power systems, are summarized. First, the development processes of partial discharge events is expressed. Then, partial discharge measurement methods are explained with application examples for power system components and their importance in maintenance management processes is emphasized. Obtained results show that, by means of partial discharge monitoring in preventive maintenance studies, it is possible to detect possible faults and prevent costly outages in power system.
