Reduction of Losses in Distribution System Using HVDS with Real Time Application

W.V.Jahnavi

The Main objective of this paper is to present the reduction of losses and maintain voltage profile constant in Distribution system by implementing HVDS over LVDS. The Overall power losses are mainly classified into Transmission losses, Distribution losses, Theft and billing deficiencies. In India, the total losses account for 32%, in which the Transmission losses share 4-6%, Distribution losses share 15 – 18% and Theft losses share 10-15%. Distribution losses and theft losses are mainly because of transmitting power at low load voltage profile to more number of consumers using High rating kVA Transformer. In case of LVDS, as more number of customers are given supply from high rating kVA transformer, as in case of any failure, more number of consumers will be affected . But in case of HVDS, less number of customers is connected to low rating kVA transformer, so, less number of customers will affect at failure. In this paper, MATLAB simulation is applied to Distribution System before implementing HVDS and after implementing the HVDS. The Voltage profiles and Power Losses are observed in both the cases. In overall economic point of view, annual savings and payback period is also determined.
