Owing to its obvious advantages such as high control flexibility, no commutation failure and strong dy-namic reactive power support capability, the voltage sourced converter based high-voltage direct-current (VSC-HVDC) transmission technology has been widely applied in scenarios including point-to-point transmission, back-to-back inter-connections and DC grids. As a core piece of equipment in VSC-HVDC transmission engineering, the VSC valve achieves AC/DC energy conversion through frequent switching of power electronic devices. In this paper, the key design requirements for VSC valves in different application scenarios are systematically summarized by combining with practical experiences accumulated in engineering, the commonly used power devices and VSC valve topologies in VSC-HVDC transmission engineering are compared and analyzed, and their development trends are projected. In addition, different schemes for two typical application scenarios in the future are also compared, providing reference for the applications of VSC-HVDC transmission technology in high-voltage, large-capacity and long-distance transmission scenarios.
