Abstract

Smart meters are an indispensable element of new generation smart grids. This study presents the hardware design of a novel single-phase smart electricity meter, which can provide energy efficiency, adaptive pricing and automated data collection functions. Besides, an extensive information is given about the Bluetooth, Wi-Fi and NB-IoT technologies that are used to transfer the electrical parameters (current, voltage, active/reactive power, power factor etc.) related with its connected load to the cloud server. Our designed smart meter has been tested by connecting to the LED lighting panel, which is supplied over the electric grid. So, the measurement validity has been verified by using the application program. Also, the smart meter readings have been successfully transferred to the mobile phone application and cloud platform with the help of available wireless connection technologies.

Çoklu Kablosuz Bağlantı Teknolojilerine Dayalı Tek Faz Akıllı Elektrik Sayacının Donanım Tasarımı

Abstract

Akıllı sayaçlar, yeni nesil akıllı şebekelerin vazgeçilmez bir unsurudur. Bu çalışmada enerji verimliliği, uyarlamalı fiyatlandırma ve otomatik veri toplama fonksiyonları sağlayabilecek özgün bir tek faz akıllı elektrik sayacının donanım tasarımı sunulmuştur. Bununla birlikte geliştirilen akıllı sayaç ile bağlı olduğu yüke ilişkin toplanan elektriksel parametrelerin (akım, gerilim, aktif/reaktif güç, güç faktörü vb.) bulut sunucusuna aktarılması için kullanılan Bluetooth, Wi-Fi ve NB-IoT teknolojileri hakkında kapsamlı bilgi verilmiştir. Tasarlanan akıllı sayaç elektrik şebekesi üzerinden beslenen LED aydınlatma paneline bağlanarak test edilmiş ve elde edilen ölçüm değerlerinin geçerli olduğu uygulama programı kullanılarak doğrulanmıştır. Ayrıca akıllı sayaç okuma değerlerinin mevcut olan kablosuz bağlantı teknolojileri yardımıyla cep telefonu uygulamasına ve bulut platformuna aktarımı başarıyla gerçekleştirilmiştir.
