Using Wireless Smart Meter Networks for Power Quality Monitoring

The novelty of our approach resides in the processing of real-time power fault events from DDS to GIS web clients in three stages, as illustrated in Figure 2: 1) When the fault overlay is selected, a DDS subscriber is internally launched and connected to the GIS client in order to capture fault events, ie voltage sags, swells and other power disturbances detected at the smart meters and substations. 2) Through a permanent link between the GIS application and the DDS subscriber, based on an atmosphere server for asynchronous web applications and Socket.IO for communication channels, fault events are transmitted in real-time to the GIS client. This technology allows any web client to interact with the service without needing to refresh the web client [3]. 3) Fault events being geolocated, they are represented on the power network where faults occur (as indicated on Figure 3) as soon as they become available on the DDS. In the case of MV / LV faults, they appear close to the substations. Faults are depicted in different colours on a green to red scale in order to show the alarm severity based on duration and magnitude of the fault.
