KR Padiyar HVDC Power Transmission Systems PDF: A Must-Read for Power Engineers

High Voltage Direct Current (HVDC) power transmission is a technology that offers many advantages over conventional Alternating Current (AC) power transmission, such as higher efficiency, lower losses, better controllability, and integration of renewable energy sources. HVDC power transmission systems are widely used for long-distance bulk power transfer, interconnection of asynchronous grids, and offshore wind power evacuation.
