A heuristic approach for optimal monitor placement for fault location

The paper proposes a faster and less memory intensive algorithm to determine the optimal location of monitors for fault location. It is developed to overcome the limitations posed by the integer programming approach when applied to large power systems. The performance of the proposed algorithm is tested in the IEEE 118-bus test system and in a 295-bus generic distribution network. The results of simulations are compared with those obtained with existing methods and show noticeable improvement.
