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 assessment

  • 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.
