Sreenivasulu Journal on Electrical Engineering 2230 – 7176 1 1 71 78 Distribution system plan, Feeder routing, Load flow, Conductor selection In this paper an attempt is made to develop an efficient algorithm for radial distribution system planning. The proposed algorithm gives optimal feeder configuration and the optimal size of branch conductors while satisfying the constraints such as reliability, current carrying capacity and minimum voltage limit. A generalized algorithm is developed for obtaining the optimal feeder path on maximum reliability and on minimum loss criteria. For branch conductor optimization, approximate load flow technique is incorporated in this paper. The proposed method is illustrated with a numerical example consisting of one substation, two feeders and 53 load nodes. July - September 2007 Copyright © 2007 i-manager publications.
