LV-sensors provide advanced measurements in the low-voltage grid. The system is capable of high-frequency sampling of electrical signals and makes use of GPS technology to synchronize measurements. The generated synchrophasors contain both magnitude and phase information like traditional phasor measurement units. This enables accurate capturing and monitoring of grid phenomena and high speed events. The sensors can be easily installed at various locations within distribution grid substations, residential areas or industry. Hence, they provide situational awareness of the whole grid.
LV-Sensors were designed as an advanced measurement tool for emerging smart grids and has research as one of its main focus areas. For this purpose the framework was designed to be open for research, academia and third-party developers. This will eventually speed up the development, deployment and validation of advanced algorithms.
The advanced measurement solution consists of a timebeacon for synchronisation, voltage- and current-sensors, and smart nodes. LV-Sensors contain an embedded Linux platform that can listen to other sensors, perform local measurements, calculations and communicate them in realtime. The smart node is an embedded computer that can capture realtime measurements from various sensors, perform calculations and communicate results with other smart nodes and/or the control centre. Deploying algorithms on specific sensors or smart nodes enables a balanced, scalable, efficient and realtime grid monitoring system. The open platform framework can be deployed on any platform (PC, server, embedded) and allows realtime monitoring, capturing of grid data and algorithms development.
This solution was developed in the projects IDEEGO/ORTEP and H2020 United-Grid. Please contact us for further information and trials.
