Abstract：In view of the simplification and lack of valve control and sub-module design verification in the joint commissioning test stage of modular multi-level flexible HVDC system, a test platform for valve control equipment and sub-modular control total access testing is designed. The platform includes merging unit (MU) simulation device consistent with engineering sampling rate, pole control device with diversified control modes consistent with engineering interface, link delay test device with perfect function, and sub-module function simulation device that can completely realize engineering sub module interface and original program verification. By connecting the valve control equipment and sub module program of Rudong project, the original program logic of the valve control system equipment and sub module is verified, and the integrity and excellence of the function of the designed test platform are also verified.
