Voltage Source Converter Based HVDC Transmission

Abstract

High Voltage Direct Current system based on Voltage Source Converters (VSC-HVDC) is becoming a more effective, solution for long distance power transmission especially for off-shore wind plants and supplying power to remote regions. Since VSCs do not require commutating voltage from the connected ac grid, they are effective in supplying power to isolated and remote loads. Due to its advantages, it is possible that VSC-HVDC will be one of the most important components of power systems in the future. Power transmission using AC system over the past years has proven to be robust and efficient. One main problem with respect to AC power transmission is the complexities involved in precise power controllability. This problem may be overcome by using VSC based HVDC system of transmission. In the present work, possibility of using VSC based HVDC transmission for evacuating power is explored.
