Abstract

This paper describes a protection scheme designed for the distribution network of the City of Saskatoon. The scheme adapts to system changes in an online mode; new relay settings are implemented as load, generation-level or system-topology changes. The software developed for this application is described. The hardware and implementation of the scheme in a laboratory are outlined. Also discussed are the consequences of the failure of the adaptive nature of the designed system. Remedial measures to be implemented in the event of such failures are proposed. Sample results obtained from system studies conducted so far are also included.
