Design of Urban Distribution Feeders for Voltage Profile Improvement & Distribution Losses Reduction

Abstract

India?s power sector is characterised by inadequate and inefficient power supply. Since the country?s independence, consumers are confronted with frequent power cuts, and fluctuating voltages and frequencies. In addition, system losses are high throughout India Transmission and distribution networks. In addition to these enormous direct losses, the indirect losses in terms of lost productivity and trade, sagging economic activity, rapidly shrinking of domestic and foreign investment in the power sector, uneconomical and misallocated investments in captive power, and reduced power generation could be many-fold. Distribution Sector requires economical system to provide electrical energy at a suitable prize and at a minimum voltage drop to reduce the voltage regulation. So, we require the economical way to provide the electrical energy by State Electricity Boards to various consumers at minimum voltage drop and reduce the regulation of voltage. Calculations & analysis will be required for load points, tie-points to select respective kVA capacity of transformers and hence the installation of suitable capacitor banks with proper locations for improvement of power factor and harmonics. This paper suggests the different methods of reduction of distribution losses in the 11kV urban distribution feeder to improve the voltage profile.
