The reporter learned from the Three Gorges group that China’s first offshore wind power flexible DC transmission project, Jiangsu rudonghai wind power project, will be connected to the grid with full capacity on the 25th, and the average annual on grid power generation will reach 2.4 billion kwh, adding a sharp tool for optimizing the energy structure and ensuring power supply this winter and next spring.
It is understood that Jiangsu Rudong East China Sea wind power project includes two offshore wind farms H6 and H10, which are located in the huangshayang sea area of Rudong County, Jiangsu Province. It is supporting the construction of two offshore booster stations, an offshore converter station, a DC cable and an onshore converter station. It has built China’s first 220 kV offshore booster station and put into operation China’s first 220 kV submarine cable.
It is reported that the offshore converter station of Rudong Rouzhi project is organized by the Three Gorges group in conjunction with relevant units of the industrial chain to tackle key scientific research and complete the construction of the first set. The main electrical equipment adopts domestic brands. It is the largest offshore converter station with the largest capacity, the highest voltage level and the largest volume in the world. The plane area is almost a standard football field and the height is about 15 floors of residential building, Be responsible for collecting and exporting the electric energy produced by the Three Gorges Rudong H6 and H10 projects (800000 kW in total) and CGN Rudong H8 project (300000 kW) with a total capacity of 1.1 million KW.
Insiders said that the flexible DC transmission technology adopted by Jiangsu Rudong project has large transmission capacity, low loss, long service life and basically unlimited transmission distance. It can effectively solve the problems of large-capacity and long-distance transmission of offshore wind farms, which is of great significance to the centralized and large-scale development and construction of offshore wind power in China and the development and construction of offshore high-capacity wind power in the future.
It is understood that the annual on grid power generation of Jiangsu Rudong H6 and H10 offshore wind power projects will reach 2.4 billion kwh, which can meet the annual power demand of about 1 million households. Compared with thermal power of the same scale, the project can reduce carbon dioxide emissions by about 2 million tons per year, adding a sharp tool for optimizing energy structure and ensuring power supply this winter and next spring.
