UHV/VSC-HVDC Transmission Converter Valve
The VSC-HVDC transmission converter valve adopts fully controlled high-power IGBT devices based on modular multilevel converter (MMC) topology to realize independent control of active power and reactive power. It features air insulation, deionized water cooling and double-row support structure.
Application Scenarios
It is suitable for converter stations below 800kV and 5000A, and meets the needs of HV long-distance DC transmission, new energy grid connection, AC power grid asynchronous interconnection, offshore wind power and other scenarios.
