Abstract :
An adaptive scheme for parallel line protection is described in this paper. This scheme uses line operation status prepared based on the field data, to adjust its zone limits in a way to achieve maximum coverage and mal-operation free behaviour. When the status signals are not available a worst case zone characteristic is used. The performance of the scheme has been tested using a simulated network and the results are presented.
