HVDC converter valve accepted by Beijing Science and Technology Commission

Recently, the Beijing Municipal Science and Technology Commission presided over the “Construction of HVDC Converter Valves (Phase I)” Concluding Receipt and Acceptance Conference, which was completed by China National Electric Power Research Institute’s directly-affiliated industrial company, CLP Power Electronics Engineering Co., Ltd. The world’s first ±800 kV 4750 amp HVDC valve with independent intellectual property rights passed the final acceptance test and the research results were highly recognized by the participating experts.

At present, the "HVDC converter valve development (phase II)" has been approved. In the future, relying on science and technology demonstration projects, it will carry out industrialization design, design software and hardware platform technology research and production test system development work.

The subject undertaking unit China Academy of Electric Power carried out work report and technical report on the subject research at the acceptance meeting. The acceptance experts reviewed the relevant materials. After questioning and discussion, the expert group unanimously believed that the project had developed a HVDC converter valve product with the world's leading level (±800 kV 4750 amps) and independent intellectual property rights. The monopoly of foreign technologies has greatly improved the technical level of China's HVDC transmission and accelerated the process of major technological achievements such as direct current transmission in China. In the HVDC transmission valve electrical characteristics, multi-physics modeling technology, structural characteristics, key components and other key technical areas have made major breakthroughs in technological innovation outstanding. During the development of the ±800 kV 4750 amp HVDC converter valve module and multiple converter valve industrial prototypes, the Chinese Academy of Electric Power has established the relevant routine test specifications and type test specifications, and applied for 3 patents, successfully completed Project tasks and assessment indicators.

It is reported that "The development of HVDC converter valve (phase 1)" as a key science and technology project tracked by the Beijing Municipal Science and Technology Commission has been fully affirmed. Experts believe that this subject can enhance the localization of HVDC valve replacement capacity and is expected to become Beijing. The new economic growth point of the major power equipment manufacturing industry will promote the development of major equipment in Beijing.
