VOLTAGE DROP CALCULATIONS & DESIGN OF URBAN DISTRIBUTION FEEDERS

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's Transmission and distribution networks. 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 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. Keywords: Punjab State Electricity Board, 11kV urban distribution feeder, ACSR conductors, voltage drop, voltage profile, coefficient of temperature rise and modulus of elasticity.
