The research and development of this product is based on the national key special project "Key Technology Research and Engineering Demonstration Application of High-Voltage, Large-Capacity and Flexible HVDC Transmission" led by China Southern Power Grid Science Research Institute.

China West Power Group, as the unit responsible for the development of the UHVDC flexible valve converter valve, has actively promoted research and development work, and conducted comprehensive research on system simulation, power module development, and valve tower design, and solved low-loss and high-power cycle life. UHV valve anti-electromagnetic interference, converter valve seismic and heat dissipation, compact space multi-physics field of strong coupling valve design and other technical problems.

And a number of key technologies have been formed. The flexible DC HVDC converter valves that were independently developed have completed all types of tests and passed the testimony of the National High Voltage Electrical Appliance Quality Supervision and Inspection Center.

This product is the world's first multi-end flexible DC power transmission project, which is the world's first high-voltage level and capacity. It is a ±160 kV multi-terminal flexible DC transmission project in South Australia and the world's highest rated voltage and 350 kV capacity has been put into operation. After the 1000 MW Yunnan Luxi flexible DC back-to-back project, China West Power Group made another breakthrough in the development of flexible HVDC converter valve, marking that the development level of China HVDC Group's flexible HVDC converter valve has reached the world level. Leading.

The advent of this product has promoted the progress of China's flexible HVDC transmission technology and further consolidated China's international leading position in this field.
