Web-based integrated solution for power system monitoring

Project description

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...
