Hardware Design of Single-Phase Smart Electricity Meter based on Multiple Wireless Connectivity Technologies

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.
