[Successful Back-feeding of Electricity to the 220kV Step-up Substation and Grid Connection of the First Wind Turbine for the Harbin 200MW Wind Power Project] From May 24 to 25, the Harbin Acheng 200MW wind power project successfully completed the back-feeding of electricity to the 220kV step-up substation and the grid connection of the first wind turbine. This breakthrough at a critical period marks the official entry of the Acheng project in the northeast region of Xintian into the final sprint stage for full-capacity operation, laying a solid foundation for achieving full-capacity grid-connected power generation by May 31. The project has a total installed capacity of 200MW, with 32 sets of 6.25MW wind turbine generators installed. Each wind turbine is equipped with a 6900kVA box-type transformer and connected to the 35kV side of the newly built 220kV step-up substation through eight 35kV power collection lines. The project also includes the construction of a 10%, 2-hour ESS in parallel, as well as a new 220kV transmission line connected to the State Grid's 220kV Xinsheng Substation, forming a "wind-ESS integrated" clean energy supply system.
