Determination of Losses in Distribution System at 0.433 kV bus Voltage in Cardiothoracic and Neuro Science Centre at AIIMS, New Delhi

Abstract

Electricity has become the lifeline of modern society, Homes, Offices, Industry, Schools, Hospitals, Transportation, Communication, Road lighting, Markets all depend on reliable Electric Supply with cheaper Prices. Life comes to a standstill without electricity. Electricity has become an integral and inevitable part of every body’s life. In all the energy sources both conventional and non-conventional, Electrical energy is the cleanest form of energy. Electrical energy is converted from various forms of conventional and non-conventional energy sources at suitable locations, transmitted at high voltage over long distance and distributed to the consumers at a medium or low voltage, however penetration of renewable energy and interconnection of Distributed Generation at distribution lateral the losses could observed is very high, hence goal should be efficient means losses in the distribution should be as less as possible and should deliver the quality power to the customer means the voltage should not contain any harmonics, it should not contain any sags, swells or flickers. The Cardio and Neuro Science Centre in AIIMS are very vast distribution system having three no 1.6 MVA Distribution Transformer and fifteen no outgoing feeder in main LT Panel for providing the electrical power to various of sub-section of Emergency and normal area through power cable. Hence determination of Energy loss is required at distribution level due to load current and source voltage and achieving for reduces the monthly energy bills consumption as well as compliance of electricity regulation of power quality and reliability indices, standards of performance of grid stability and environmental obligations such as carbon foot print reduction.
