Abstract

Analogue solution of energy measurement do not synchronize to a clock or crystal but calculates the product of current and voltage continuously thus facing the lack of stability, accuracy drifts over large variations in operating environment and long periods of time. In this research, we have introduced a single core hardware module to implement digital residential electric meter with a single system clock. This digital energy meter development is focused on home usage since it employs a single-phase power system. The model architecture comprises of four main modules: power, energy, billing and display. Reprogrammable devices such as Field Programmable Gate Arrays (FPGAs) are highly attractive options for hardware implementations of proposed algorithm as they provide potentially much higher performance than software solutions and generate low-cost prototypes of designs. The design is modularized and each module is modelled individually using hardware description language VHDL. This is followed by the timing analysis and circuit synthesis for the validation, functionality and performance of the designated circuit, which supports the practicality, advantages and effectiveness of the proposed hardware realization for the applications with a maximum clock frequency of 31.4 MHz. It is proven that the model has been tested successfully and follows the behaviour of a conventional energy meter.
