The construction of valve control system for HVDC converter valve is one of the key technologies and basic measures for valve control system development, factory testing and failure analysis. However, valve control system manufacturers have only been able to perform functional tests under simplified configuration. Realizing closed-loop simulation of all operating conditions, the hardware and software design of the valve control system cannot be fully verified, and the software version cannot be effectively controlled.
As a leader in the field of DC transmission in China, the State Grid Smart Grid Research Institute has been paying attention to the research of key reliability technology for HVDC transmission projects. Since 2009, relying on a series of scientific and technological projects of State Grid Corporation, it has independently developed for five years, and has broken key technical problems such as experimental equivalence study, experimental method research, and experimental device development, and proposed an equivalent test method for all conditions of valve control systems. , Developed a full-state dynamic simulation test platform for valve control system, and realized the function and interface of the valve control system and the complete equivalent of the actual project. Based on the platform's valve control system black box, engineering interface, continuous operation reliability and other testing techniques, can effectively find the hardware and software defects. At the same time, the valve control system for engineering can be delivered directly after testing on the platform, and the software version can also be well controlled.
The successful development of the full-state dynamic simulation test platform for the HVDC power transmission valve control system fills the gap in the field in China and further consolidates the leading position of the State Grid Smart Grid Research Institute in the field of UHV converter valves.
In the next step, the State Grid Smart Grid Research Institute will continue to promote the optimization and upgrading of the full-motion dynamic test platform for valve-control systems, realize the testing functions of valve systems of different technical routes as soon as possible, and provide a solid foundation for the construction of UHV DC projects of the State Grid Corporation of China.
