Hardware-in-the-Loop Test Method for Valve Base Controller of VSC-HVDC

The Zhangbei flexible DC power grid project is the world's first voltage source converter based high voltage direct current (VSC-HVDC) project, which brings higher requirements for the reliability of valve base controller (VBC). In order to comprehensively test the VSC-HVDC valve control equipment, a hardware-in-loop test method is proposed in this paper for the full-scale accessing of high voltage and large capacity VSC-HVDC VBC to the real-time simulation system. Through developing an I/O interface chassis, a full-scale access testing platform for VBC in Beijing Station was built based on RT-LAB, and the comprehensive test items and test methods for VBC were proposed. By studying the testing waveforms of several typical working conditions of the platform, the built platform is proved effective and accurate for VBC testing. This test platform has been applied in the certificate of analysis (COA) of VBC in Zhangbei VSC-HVDC Project, and it can also provide reference for the VBC testing in other VSC-HVDC projects.
