Web-based integrated solution for power system monitoring
ewz is an electricity producer and a distribution company, mainly in the city of Zurich. In 2009, the company decided to install UMG devices in selected transformer stations at the low-voltage level in order to monitor load profiles, power availability, and power quality.
The NQS software collects the values from these UMG devices, analyzes them, and informs the users via a web application, wall displays, and e-mail. The functions offered include:
- Visualization of online and archive measurements as tables, load curves...
- Power quality monitoring, i.e. diagrams of PQ values, visualization of Vdips and swells, calculation of the quality margin, weekly reports (EN 50160)...
- Monitoring of systems and installations: Load shedding in the event of underfrequency, monitoring of power factor, islanding, phase angle...
