Development and demonstration of a cost effective remote monitoring device for small embedded generation sites connected at 11kV.
Small scale embedded generation sites connected on the 11kV distribution network are increasing in number, but these sites are not normally monitored. Without data from these sites, the quantity of real demand on a feeder is effectively masked by the generation and this presents difficulties for both; real time operational decision making, and for network design.

A traditional Supervisory Control and Data Acquisition (SCADA) Remote Terminal Units (RTUs) could be installed but this is not considered to be a cost effective solution.

The larger 11kV embedded generation sites need additional monitoring facilities and this is being addressed in a second phase of this project, which will provide the following:

  • Tripping of switchgear controlling the generation

  • Close inhibit control of the switchgear

  • G59 Protection operation indication.
