To develop new algorithms improve the stability of Loss of
Mains (LoM) relays to transient events.
A six month focused research investigation exercise concentrating on the
task of validating a voltage phase displacement based anti islanding
detection method was undertaken. The main objectives of this first stage
exercise were as follows:
- To review and refine the proposed methods for the LoM detection
- To refine existing test scenarios for the LoM detection performance
- To develop and test in software (using Matlab environment) an accurate
transient model of the selected algorithm
- To implement the resulting algorithm on the AREVA P341 platform.
