Rudong Offshore Wind Power Flexible DC Transmission Project was put into operation last Saturday, marking that China has broken the foreign technology monopoly on offshore wind power transmission via flexible DC.
At 9:58 last Saturday, in the central control room of the Green Valley Converter Station, as the wind turbine power curve on the large monitoring screen continued to climb, the offshore wind power flexible DC transmission project with the highest voltage level and the largest transmission capacity in the world was put into operation with 3.3 billion kWh of electricity to be supplied to the grid each year.

This project has achieved China's "zero" breakthrough in the field of flexible and straight offshore wind power.The flexible DC transmission technology is currently the most cutting-edge transmission technology in the world.
Flexible DC technology is a new type of DC transmission technology that can effectively control the passing electric energy, just like inserting a fully controllable "water pump" into the power system, which can precisely control the direction, speed and flow of the "water flow".
For a long time, the technology of sending offshore wind power via flexible DC has been monopolized by a few European countries. For the first time, Rudong Offshore Wind Power Flexible DC Transmission Project applies flexible DC transmission technology to the field of offshore wind power transmission.
Its operation shows that China has the capability of large-capacity offshore wind power development and construction and equipment supporting capabilities, completely breaking the foreign technology blockade.

This project is independently completed in terms of design, equipment manufacturing supply, and engineering construction which has empowered us with independent intellectual property rights.
