WIRELESS AND CARRIER COMMUNICATION BASED SMART METERING FOR A MICROGRID SYSTEM TO CONTROL AND MONITOR POWER QUALITY

The paper describes the smart meter module for microgrid. In order to monitor and manage the micro - grid system, design of monitoring system and control capability, which contains hardware device. Hence real time implementation is adopted in software and hardware model. MPLAB and its program modules in software constitute with hardware device. It describes the probable methods of implementation for smart metering microgrid sources and load feeders. Smart meter meas ures real time parameters of a supply and process auxiliary to determine rms, peak and distortion in phase voltages and currents. Real power and reactive power is determined using measured voltages and currents and communicated using smart meters supported by GPRS. It also results in higher order harmonic which is not desirable to the loads. The microgrid smart metering system that is monitoring and control system have been implemented and experimentally validated in a real size microgrid which operate cont inuously.
