Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Abstract

A local electrical system having an electrical generator is connected to an electrical generator network. The local electrical system has a controller to avoid the non-detection zone of loss-of-mains relays. The controller is arranged to monitor the real power flow from the electrical generator network to the local electrical system and to determine if the absolute value of the real power flow is below a first predetermined value to determine if there is a close match between the power requirements of the local electrical system and the electrical generator. If there is a close match, then the controller is arranged to monitor the reactive power flow the same way. If there is a close match also with the reactive power, then the controller is arranged to adjust the target reactive power output from the electrical generator of the local electrical system.
