Recently, the first batch of power units for the Qinglong Jianhao Tumenzi 215MW photovoltaic project, undertaken by China Electric Power Construction Group Hebei Engineering Co., Ltd., were connected to the grid for power generation.

The project is located in Qinglong Manchu Autonomous County, Qinhuangdao City, with a planned installed capacity of 215MWp. The photovoltaic modules will use 540Wp and 545Wp single crystal silicon double-sided double glass battery modules, equipped with 225kW series inverters. The box transformer will use American transformers with specifications of 3150kVA, 2500kVA, 2000kVA, 1600kVA, 1250kVA, and 800kVA. Simultaneously build a 220kV step-up collection station, a 6-circuit 35kV overhead collection line (14 kilometers), and a 1-circuit 220kV transmission line (28 kilometers), and organize the expansion interval construction of the higher-level 220kV substation.

Since the start of the project, personnel from various positions in the project department have been closely monitoring the safety, quality, and progress of the project, and organizing daily production coordination meetings. Under unfavorable factors such as short construction period, high construction difficulty, and complex coordination work, the project department, together with various construction teams, worked together to overcome various construction technical difficulties. To ensure that the first batch of grid connected construction tasks are completed on schedule, with quality and quantity guaranteed, the project department adjusts the schedule, increases construction personnel, and continuously operates at various construction interfaces. The project department's management personnel stand by at low temperatures and conduct low-temperature inspections to ensure construction safety and quality. The project builders set the same goal, think together, and work together to unleash the strongest strength of unity and cooperation.

After the project is put into operation, the annual equivalent available hours are 1495.7 hours, and the average annual power generation in 25 years reaches 321.5676 million kWh. It can save 89661.5 tons of standard coal and reduce greenhouse gas carbon dioxide emissions by 242000 tons per year for the country, equivalent to 225 hectares of afforestation. Provided green support for promoting local ecological improvement and high-quality economic development. Editor/Zhao E
