An Overview on High Voltage Direct Current Transmission Projects in India

With the increase in energy demand, the need for an efficient and stable transmission system is required. However, transport of bulk power and over long distance gives rise to considerable problems like variation of voltages profiles, decrease in power transfer, and generation of reactive power, so rapid advance in DC transmission technology has been taken place because it has numerous advantages over EHV AC transmission. This paper illustrates the recent developments in the HVDC Transmission System in India, also a comparative analysis between the EHV AC Transmission System & HVDC Transmission system, and an overview of projects of HVDC power plants in India is presented.
