Time: 2023.
Location: Ningbo, Zhejiang.
This project is located in the southeast sea area of Nantian Island, Xiangshan, Ningbo. With a total installed capacity of 504MW, it is the largest offshore wind power project under construction in Zhejiang Province in 2023. The project has been included in the list of key construction projects in Zhejiang Province during the "14th Five-Year Plan" period. After the full-capacity grid connection of this project, it is estimated that the annual online electricity generation will be as high as 1.64 billion kWh. The total investment of the project is 5 billion yuan. It uses 56 doubly-fed units. This unit is the doubly-fed unit with the largest single-unit capacity that has been connected to the grid at sea in 2023. Among them, 28 units are equipped with Hopewind's water-cooled doubly-fed three-level 9MW (stator medium voltage) converter. The project is located in a rotating tidal sea area. The hydrological and meteorological conditions are complex, and it is difficult for ships to dock. Moreover, the resources for operation and maintenance ships are scarce. Ships go out and return on the same day, resulting in extremely tight effective debugging time. The Hopewind after-sales team goes out early and returns late, formulates a perfect debugging plan, seizes every window period to efficiently complete the debugging task, actively cooperates with the customer's grid connection goal. The success rate of one-click startup and grid connection is 100%, winning consistent praise from customers. At present, the debugging of this project is still proceeding in an orderly manner.
