Smart meter prototype design

Abstract

An example of smart meter prototype development is discussed with software and hardware architectures. By selecting a standard energy measurement chip (ADE7758) together with a microcontroller (PIC 18F452), a real time clock IC (PCF8583), and a GSM module (SIM900), the prototype is designed. Hardware configurations and software algorithms are illustrated and discussed so that the reader can easily read and understand the real structure of a smart meter. Three phase, per phase, time and date information are displayed on a LCD at the meter side. The data processed at the smart meter are sent to a remote server in every 15 min intervals. Consumption details including the electricity cost, average energy usage, average daily cost, predicted electricity cost of the month, and the number of remaining days for specified credit levels are calculated and displayed at the server side. This smart metering system illustrates the two way interaction between the consumer and the utility together with information service.
