Minimization of Losses in Radial Distribution System by using HVDS

The loads in rural area are predominantly pump sets used for lift irrigation. The loads have low power factor and low load factor. Further, load density is low due to dispersal of loads. The existing distribution system consists of three-phase 11 kV/433 Volts distribution transformer with lengthy L.T Lines. In this system, the losses are high, voltage profile and reliability are unsatisfactory. In this paper, HVDS has been introduced with small capacity distribution transformers. A simple load flow technique has been used for solving radial distribution networks before and after implementation of HVDS. An advantage of implementing HVDS over LVDS system is discussed.
