Voltage profile improvement through 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 and voltage profile leads to affect the performance of the existing distribution system. In this work a high voltage distribution system has been proposed and the simulation studies were carried out for an existing TNEB High Court Sub Station using PSCAD Software. The HVDS simulation study re veals that the system voltage at the tail end increases approximately by 20Volts. 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.
