Wireless web-based power quality monitoring system in a microgrid

This paper presents a real-time power quality monitoring system for microgrids. The Smart Meter consists of a metering unit, an ARM® Cortex®-M4F microprocessor and a wireless (IEEE 802.11) module that allows a bidirectional exchange of information between the Smart Meter and a data center. Motivated by the ubiquitousness of Web applications, a Web platform was developed to permit the visualization and management of the microgrid. With the data, the system can realize acquisition of electricity information, anomalous measurements, alerts, electric power quality monitoring and analysis of the collected information.
