Abstract
The paper proposes a heuristic method for optimal placement of sectionalizers in distribution electrical networks without automatic reservation. The method consists in dividing the network into segments with the same total line lengths and finding the optimal location of the sectionalizers around the dividing points. Based on the method, an algorithm was developed and calculations were performed to determine the optimal locations of sectionalizers and expected indexes of power supply reliability for a fragment of the distribution network.
