Analysis of Electricity Consumption in Low Voltage Distribution Systems in Karabük

Abstract

Electrical Interior Installation Projects; It is the most basic platform where the electrical installation needs of the buildings are specified. All projects and calculations in these projects; Electrical Interior Facilities Regulation, Electrical Facilities Project Preparation Regulation, Cable Chimney and Energy Chamber Measures and Details of the Application Areas and relevant local circulars are made with reference. The prepared projects are controlled and approved by the responsible Electricity Distribution Companies again with reference to the provisions of the legislation mentioned above. In Electrical Interior Installation Projects; One of the most important calculations affecting the security, cost and efficiency of the facility is the “demand power” account. “Demand power toplam is obtained by multiplying the sum of all the electrical powers specified in the project (installed power) with appropriate“ concurrency coefficients göre according to the characteristics of the powers (lighting load, socket load, mechanical load, etc.). The measurement, transmission and protection elements of the plants are selected with reference to the demand power. Consequently, “concurrency coefficient” plays an important role in the Electrical Interior Installation Projects in order to determine the electrical materials of the buildings at ideal values. Currently, demand power calculations in Electrical Interior Installation Projects; It is based on the concurrency coefficients mentioned in Article a.2 of Article 57 of the Electricity Indoor Facilities Regulation which is prepared many years ago and cannot respond to the developments in today's conditions and continuously renewed technology. Performing the demand power calculation under ideal conditions in parallel with the developing living standards and current technology will increase the reliability of the performance and cost of the electrical installations of all buildings. In this article, we will analyze the real consumption values of 1814 buildings, 5591 customers and 4 years for Karabük Province, that the concurrency coefficient does not meet current needs, that there are large differences between real values and calculated values and what is the cost effect of this difference. Thus, the importance of the concurrency coefficient will be emphasized.

Karabük İlindeki Alçak Gerilim Dağıtım Sistemlerinde Elektrik Tüketiminin Analizi

Öz

Elektrik İç Tesisat Projeleri; yapıların elektrik tesis ihtiyaçlarının belirtildiği en temel platformdur. Bu projelerde tüm tasarım ve hesaplamalar; Elektrik İç Tesisler Yönetmeliği, Elektrik Tesisleri Proje Hazırlama Yönetmeliği, Kablo Bacasi Ve Enerji Odasının Ölçü Ve Detayları İle Uygulama Alanlarına İlişkin Esaslar ve ilgili lokal genelgeler referans alınarak yapılır. Hazırlanan projeler sorumlu Elektrik Dağıtım Şirketlerince yine yukarıda belirtilen mevzuat hükümleri referans alınarak kontrol edilir ve onaylanırlar. Elektrik İç Tesisat Projelerinde; tesisin güvenliğini, maliyetini ve verimliliğini etkileyen en önemli hesaplamalardan biri “talep gücü” hesabıdır. “Talep gücü” projede belirtilen tüm elektriksel güçlerin toplamı (kurulu güç) ile güçlerin niteliklerine (aydınlatma yükü, priz yükü, mekanik yük vs.) göre uygun “eş zamanlılık katsayılarla” çarpılması ile elde edilmektedir. Tesislerin ölçü, iletim ve koruma elemanları talep gücü referans alınarak seçilmektedir. Dolayısı ile yapılara ait elektriksel malzemelerin ideal değerlerde belirlenebilmesi için Elektrik İç Tesisat Projelerinde “eş zamanlılık katsayısı” büyük rol oynamaktadır. Mevcut durumda Elektrik İç Tesisat Projelerinde talep gücü hesaplamaları; yıllar önce hazırlanan ve günümüz şartlarındaki gelişimlere ve sürekli yenilenen teknolojiye cevap veremeyen Elektrik İç Tesisler Yönetmeliği’ nin 57.MADDE sinin a.2 bendi’nde belirtilen eş zamanlılık katsayıları referans alınarak yapılmaktadır. Talep gücü hesabının gelişen yaşam standartları ve güncel teknolojiye paralel olarak ideal şartlarda yapılması tüm yapıların elektrik tesislerinin performans ve maliyet bakımından güvenirliliğini artıracaktır. Bu makalede eşzamanlılık katsayısının güncel ihtiyaçları karşılamadığını, gerçek değerlerle hesaplanan değerler arasında büyük farklar olduğunu ve bu farklılığın maliyet etkisinin neler olduğunu Karabük İli için 1814 yapı, 5591 müşterinin, 4 yıllık gerçek tüketim değerlerini analiz edeceğiz. Böylece eşzamanlılık katsayısının önemi vurgulanmış olacaktır.
