On March 25, 2023, the first wind turbine of the Laolu Liangzi 66 MW wind power project of the Dianzhong New Energy Division of Datang Yunnan Company was successfully hoisted, laying a solid foundation for the project to be put into operation on schedule.

The project is located in the mountains of Wuzhai Township, Yongshan County, with an altitude of 3,000 to 3,100 meters. It is planned to install 11 wind turbines with a single capacity of 6 MW, with a total installed capacity of 66 MW.

Since the start of construction of the project, the Dianzhong New Energy Business Department has given full play to the role of the party committee in setting the direction, managing the overall situation, and ensuring implementation. Members of the party committee have stepped down to the front line, set up a youth commando team for engineering construction, and maximized the release of the leading + effect of party building. . The project department solves problems and tackles key problems in all important links of project promotion, and fully promotes the pre-project procedures to ensure that the project complies with laws and regulations.

After the start of the project, the epidemic situation has been repeated. The project department took the initiative to strengthen coordination and services, unblock the transportation channels of building materials, and help the smooth construction of the project. Cement and steel bars are important materials for project construction. Affected by the epidemic, traffic control was implemented in many places, and the transportation of building materials was restricted, which seriously restricted the project construction. The project department actively communicates with the local government, adopts point-to-point, dedicated delivery, and dedicated docking. The pick-up and drop-off personnel supervise the whole process, and the delivery driver does not get off the car or contact with others. Closed-loop management is implemented for workers and transport vehicles, ensuring all kinds of raw materials Transportation to ensure that production and construction will not stop during the epidemic.

During the pouring period of the fan foundation, it was in the severe winter, and the temperature was often below zero, which seriously affected the concrete pouring of the fan. The project department organizes the participating units to hold seminars every day to discuss how to advance the next work. After many discussions and brainstorming, a plan was finally decided to do a good job in the maintenance of the mixing equipment to ensure that the equipment does not freeze and can be used at any time. The mixing water is heated and the concrete is stirred with warm water. After the foundation of the wind turbine is poured, it should be covered with felt for heat preservation and maintenance to prevent the concrete foundation from being damaged by freezing. The project department overcame the impact of the cold weather in only 56 days, completed the foundation pouring of 11 wind turbines, and completed important engineering nodes, laying a solid foundation for the smooth completion of the project.

The project is located in a high-altitude area with a 70-kilometer approach road, passing through three towns and ten villages. The slope is steep, the road surface is narrow, there are many curves, and the residential power lines are intricate. The transportation of large components faces huge challenges such as roadblocks and air barriers. The business department appointed a special person to communicate with the residents along the way, explaining to them the convenience brought by road reform and expansion, the line renovation replaced the old line and the old line, making electricity use safer. After repeated persuasion by the staff of the project department, the surrounding residents agreed to the renovation and construction; at the same time, the project department actively communicated with the relevant local functional departments, and with their support, fully promoted the road improvement. The road reform was successfully completed, which not only facilitated the transportation of large parts of the project, but also played a positive role in consolidating and expanding the achievements of poverty alleviation and rural revitalization.

The center of the hub of the project is 110 meters above the ground, and the length of a single blade is 94.5 meters. It is currently the wind season, and hundreds of tons of equipment must be hoisted at a height of 100 meters. Short and so on. When the wind is strong and the fog is strong, the danger is great. We must accurately grasp the only small wind time every day, and ensure that all tasks are completed safely and efficiently according to the plan. said the person in charge of the project. In order to ensure the smooth completion of the hoisting task, the business department attaches great importance to it, carefully deploys it, takes multiple measures, and sets up a special class to designate a special person to ensure the effective connection of all construction links. The single-blade hoisting scheme is unlocked according to the time and situation, and the windward side is smaller, which greatly prevents the side load from exceeding the lateral anti-side ability of the crane, and the hoisting of the first wind turbine is completed efficiently and smoothly.

In the next step, the project will continue to be promoted as a whole, and supervision will be increased. In accordance with the general tone of safety first, stability, progress while ensuring stability, and highlighting key points, we will ensure full investment, do our best, and be able to work as quickly as possible. Guided by the super three zeros, rationally use the hoisting window period, fully promote the hoisting of wind turbines, ensure that the project tasks will be completed within the deadline, and make new and greater goals for Yunnan Company to achieve the three goals of one million and the fourth double in 2023 contribute.Editor / He Yurong
