Abstract : In this paper, the idea of a prepaid energy meter with a flexible billing unit using FPGA for household as well as for industrial consumers has been introduced. It explores the design, implementation and application of billing automation system for consumer applications. The major drawback of traditional energy meter system is that the cost for the energy consumed should be calculated manually using man power. This process is time consuming. Hardware structure of the power factor and energy is designed using VHDL and simulation are done using ModelSim.The final results verifies the functionality of the proposed design. In this work energy has been calculated using two inputs namely voltage and current (both are single phase), which is then feed into energy meter and its corresponding cost are calculated as the excepted outputs. This design gives improved security, higher reliability, higher accuracy, higher performance, and takes less memory to store the power and also greatly reduces the size of a meter. Area occupied by the proposed design is 20% less than the conventional method.
