Beijing, Nov. 22 -- State Intellectual Property Office of China has released NARI Relays Electric and Nanjing NARI Relays Eng Tech's patent application for offshore wind power direct-current grid-connected system platform. This invention was developed by Zhan Changjiang, Wei Xudong, Yu Haibo, Gao Biao, Wang Tao and Fang Taixun.
The patent application number is CN201910707650 20190801. The patent publication number is CN112398160 (A). International Patent Classification codes are E05F15/71, E05F15/72, H02J3/38 and H02J5/00. Cooperative Patent Classification codes are E02B17/00 (CN), E05F15/71 (EP), E05F15/72 (EP), H02J3/38 (EP), H02J5/00 (EP, CN) and Y02E10/76 (EP).
According to the abstract released by the State Intellectual Property Office of China: "The invention discloses an offshore wind power direct-current grid-connected system platform for an offshore wind power plant. The offshore wind power direct-current grid-connected system platform comprises a main system sub-platform, an auxiliary system sub-platform and one or more gallery bridges. The main system sub-platform comprises a grid-connected system and power transmission and conversion equipment. The auxiliary system sub-platform comprises a supportive auxiliary device. The gallery bridge physically and electrically connects the two platforms, and the gallery bridge has a fireproof function. According to the scheme, through technical integration and optimization, an original large offshore platform is split into two sub-platforms easy to construct, the size of a single offshore platform is reduced, the weight of the single platform is reduced, and the manufacturing cost and the offshore construction difficulty are reduced; and the personnel living and working area is arranged on the grid-connected auxiliary system sub-platform, and an isolation measure is set between the personnel living and working area and the grid-connected system main platform part, so that bettersafety is achieved."
