High Voltage DC Transmission

High Voltage DC Transmission. Instructor: Prof. S. N. Singh, Department of Electrical Engineering, IIT Kanpur. In early invention of electric energy, dc power was used but due to limitations of low voltage DC systems, AC systems become popular. With increase interconnection and loading of power system, the factors such as are reactive power, stability, power control, etc, impose limitations on the amount of power to be transmitted over AC lines. With advent of high voltage semiconductor devices, it has been possible to go for high voltage DC (HVDC) transmission for long distance power transfer. This course will provide in-depth knowledge of HVDC system, converter topology, control of HVDC system, filters, analysis of HVDC/HVAC systems, etc. (from nptel.ac.in)
