Abstract :
This paper presents a method for optimal placement of reclosers and sectionalizers in overhead distribution networks to reduce non-distributed energy (NDE) caused by faults. This method also considers costs of reclosing shuts on the supplied loads and substation transformer from power quality point of view. The proposed algorithm uses an effective numbering method to determine the distribution network topology. Then a method is described for optimal placement of a recloser and sectionalizers in the network. Both voltage type and current type sectionalizers are considered at this stage. In the next stage, the optimal number of sectionalizers is determined based on economic considerations. Lastly, the validity of the presented method is evaluated by applying the algorithm on a typical Iranian 20 kV overhead distribution feeder and the results are presented
