ABSTRACT A high voltage direct current (HVDC line) electric power transmission system using direct current for transmission of electric power. The evolutionof industrial growth during the recent years has lead to increased consumption of electrical energy. When a bulk power is to be transported over very long distances, HVDC transmission system is used which is more economical compared to AC transmission system. HVDC also suffer lower electrical losses. Since the power flow through the HVDC link can be controlled independently of the phase able between source and load, it can stabilize a network against disturbances due to rapid changes in power. Also, improvement in stability and economy of each grid is found, by allowing exchange of power between incompatible networks due to these advantages over AC lines, HVDC is preferred. This proposed model uses existing infrastructure of HVAC a line to convert it into HVDC lines. The surplus generation of electric power can be reduced by employing HVDC for transmission as the losses in this is only 3% per 1000KM. This in turn reduces the coal consumption in thermal power plants. This impacts on life span of coal reserves in India.
