Voltage source converter based high voltage direct current（VSC-HVDC） technology as the new generation of DC transmission technology, has been developed and applied globally. The world＇s first real bipolar high-voltage large-capacity VSC-HVDC transmission project——Xiamen ±320 k V/1 000 MW VSC-HVDC demonstration project is described. The operation mode and control strategy of Xiamen project are analyzed and summarized. Furthermore, the structure of control system and elementary diagram of the direct current control strategy are discussed. The operating performance of the system under different operation mode is tested, which provides theoretical basis and experiences for the engineering practice of high-voltage large-capacity VSC-HVDC transmission technologies.
