Restructuring of Existing Distribution System with High voltage Distribution system

The Power Requirement in urban and metro areas is very high with an exponential growth. The distribution system with LVDS results in multiple loads fed from a bulk power transformer resulting in higher regulation in the tail ends. Moreover there is an increase in the system losses, power factor, voltage profile and performance are affected in the existing distribution system. Losses in an electrical system should be around 8 to 14% .In developed countries it is not greater 10%, however in developing is country, the percentage of active power losses is around 30%.In this work comparative analysis between high voltage distribution system and low voltage distribution system has been done and also payback calculated. the studies were carried out for an existing distribution system. This may result in extended lifetime of the equipment and reduction in system loss. New transformers of low capacity may have to be introduced for implementing the proposed system and the existing transformer of high capacity have to be relocated suitably to achieve the advantage of HVDS.The investment may be two times compared to LVDS and the increased cost is affordable as HVDS is more beneficial.
