Set a "small goal" of 100 million profits first! Huaneng Zhangbei trouble-free wind farm refining record

"People work hard, and equipment helps." With the blessing of reliable units, intelligent operation and maintenance, and the atmosphere of catching up with learning, Wang Xiangwei, deputy director of the maintenance center of Huaneng New Energy Hebei Branch (presiding over the work) and director of Zhangbei Central Station, also set a "small goal of making a profit of 100 million" this year.

Zhao Jianyong, general manager of Huaneng New Energy Co., Ltd., told Fengmang Energy that in the future, it plans to summarize the successful experience of "trouble-free wind farms" in Zhangbei and strive to build more "trouble-free wind farms". With the construction of more and more "trouble-free" wind farms, Huaneng is also studying and actively obtaining opportunities for cooperation and development of overseas new energy projects, giving full play to the advantages of all parties to go to sea by boat.

Set a "small goal" of 100 million yuan first

"If this batch of projects is not rushed, the 3.8 billion yuan income will be directly gone." A few days ago, at the "Most Beautiful Wind Farm" event hosted by Wind Energy magazine, Wang Xiangwei told Fengmang Energy.

Huaneng Zhangbei Wind Farm is located in Baimiaotan Township, Zhangbei County, Zhangjiakou City, Hebei Province, developed and constructed by Huaneng Zhangbei Wind Power Co., Ltd., with a total installed capacity of 242,000 kilowatts, and the third phase of the project has an installed capacity of 50,000 kilowatts, using 16 SE14630 and 1 SE12120 unit. The project was connected to the grid at full capacity at the end of December 2020.

Wang Xiangwei said, "At that time, it was mainly the locking of some resources, and Sany Renewable Energy gave great support in this regard. Especially in the area of supply. In addition to the fans that were in short supply at that time, there was also a lack of some materials involved in hoisting on site. Everyone is scrambling for time, and Sany Renewable Energy has directly supported our materials of more than 800,000 yuan. ”

In winter, the temperature in Zhangjiakou can reach minus 40~50 degrees at night. I have to deal with "iron bumps" every day. In order to rush the load, there is no way but to overcome. "The happiest thing at that time was to eat the bag of hot eggs in the captain's arms at night." The on-site staff said. Under the high-intensity working pressure, even the No. 9 wind turbine with sudden problems in the angle of the engine room was connected to the grid three days earlier than expected.

Zhangjiakou divides the dam up and down. The Bashang area is rich in wind resources and has a large installed capacity. The capacity of the booster station supporting the power grid is less than the total installed capacity, and the main transmission lines, Zhangxiong UHV and flexible DC transmission capacity have not been fully released for the time being. Wang Xiangwei said that under various "power rationing", in order to maximize the utilization hours of the wind farm, the team decided to do a good job in equipment management, and the light wind can be exhausted when the power is not limited; Evaluate the transaction, formulate an active trading strategy, and exchange the power generation rights through the transaction.

In 2021, Huaneng Zhangbei Wind Farm was rated as one of the top ten benchmark stations of Huaneng Group.

From January to July this year, the average wind speed of the wind farm was 4.73m/s, and the utilization rate of wind turbines was further increased to 99.98%. "For other stations in the same period, the annual utilization hours can reach 1,600 hours, which is already very good. As of August 1, our 50,000 kilowatt project has been completed for 1,400 hours. There are still 4 months left, and there should be no pressure to pass 2,000 hours this year. Wang Xiangwei told Fengmang Energy.

"Last year, the project made a profit of more than 80 million yuan, and it should be no problem to exceed 100 million yuan this year." Wang Xiangwei said with a smile, "The most important thing to pay attention to every day is the amount of power generated, especially the one next to another wind farm." We are competing and learning to catch up in the atmosphere to see who can make a profit of 100 million first. ”

People work hard, and equipment helps, too

"The results have been impressive. This result is due to the hard work of the people, and the equipment helps. Wang Xiangwei emphasized, "The premise of all achievements is the high reliability of the equipment. That is, when it can be sent, when it needs to be sent, the fan cannot drop the chain. ”

Wang Xiangwei, who has a technical background, told Fengmang Energy, "When I tendered and locked the manufacturer, I was beating the drum in my heart. However, after seeing the drawings of Sany Renewable Energy, the control logic of the main controller, the selection of the main components and the on-site observation, the doubts were dispelled. Willing to use materials, reasonable design, confident. ”

"The Zhangbei Wind Farm is located in a small basin. The 100-meter-high tower measures the income, which does not meet the profit requirements. Due to cost, technical considerations, etc., it was finally decided to use the 140-meter flexible tower to use the wind resources at the height. The wind farm later became a benchmark for the use of 140-meter flexible towers. Zhao Jianyong said that Sany Renewable Energy is rigorous and responsible, fully considers the local resource conditions in the design concept, and adapts to the local operating conditions in the selection of large components and supporting equipment.

"Wind turbine blade manufacturing is a labor-intensive industry. Process quality control is crucial in this regard. Taking QC as an example, the proportion of manufacturing is generally not more than 3%. However, in Sany Renewable Energy Blade Company, the proportion of QC and front-line employees is close to 10%. Jin Tao, general manager of the Zhangjiakou base project of Sany Renewable Energy Blade Company, said, "Looking at the blades alone, the quality investment is not low. The ultimate goal is to ensure quality. ”

"The 50,000 kilowatt wind farm where Sany Renewable Energy units are installed is in very good condition so far, and there has been no unplanned outage." Zhao Jianyong believes that this is the concrete embodiment of Sany Renewable Energy's excellent wind power products and services.

"There are fewer unplanned things, and the scene is relatively less hard. Colleagues have more time to learn and improve themselves. Wang Xiangwei said. Huaneng Zhangbei Wind Farm has a total of 10 operation and maintenance teams, including 7 from Huaneng and 3 from Sany Renewable Energy. Huaneng personnel are responsible for the quality and safety supervision of power transmission and transformation equipment maintenance and fan maintenance process, and participate in part of the wind turbine maintenance work with Sany Renewable Energy in a timely manner; Sany Renewable Energy personnel are mainly responsible for the maintenance of wind turbines, including planned defect elimination, technical transformation, and fault elimination. "In the wilderness, work together, live together. Although wearing different work clothes, closing the door is a family. Wang Xiangwei sighed.

Create more "trouble-free wind farms" and go to sea

Digital transformation and smart O&M are equally important to the creation of "trouble-free wind farms".

All data from the operation of Huaneng Zhangbei Wind Farm is connected to the Jibei Centralized Control Center of Huaneng New Energy Hebei Branch, and the data is synchronously transmitted to Shijiazhuang Centralized Control Center of Huaneng New Energy Hebei Branch, Huaneng New Energy Operation and Maintenance Center, and Huaneng Group Smart Operation and Maintenance Center.

"These big data platforms for centralized control and operation and maintenance centers are all developed by Huaneng itself. The Hebei Centralized Control Center is mainly responsible for remote monitoring and control, and some data analysis; Huaneng New Energy Operation and Maintenance Center is mainly responsible for data analysis and early warning within the scope of new energy companies. Huang Lizhe, deputy director of the production and environmental protection department of Huaneng New Energy Co., Ltd., said, "Through the whole region, all models, and all data collection, real-time summary, calculation, and analysis of data information." Continuously optimize the existing processing methods, propose optimal solutions, give full play to the role of digitalization in early warning and efficiency improvement of operation and maintenance, and gradually realize the transformation from the traditional passive maintenance mode to active preventive maintenance. At present, the platform can achieve accurate fault warning for large parts of the unit 20 days in advance, reducing the failure rate by more than 30% and the fault handling time by more than 29%. "Under the management of the smart operation and maintenance mode, the work efficiency and safety production management level of the station have been greatly improved.

Zhao Jianyong told Fengmang Energy that Huaneng New Energy Co., Ltd. has a good cooperation with Sany Renewable Energy. In the future, the two sides will further build consensus, broaden the scope of cooperation, and promote mutually beneficial development. In particular, in the field of improving the quality and efficiency of existing wind turbines, Huaneng New Energy Company plans to summarize the successful experience of "trouble-free wind farms" in Zhangbei, increase the production and technological transformation of other projects, further reduce the failure rate of wind turbines, improve the power generation efficiency of wind turbines, and strive to build more "trouble-free wind farms".

Yu Liangwei, deputy general manager of Sany Renewable Energy and general manager of the marketing company, said that Sany Renewable Energy has implemented a R&D personnel doubling plan since 2019. "We hope that through continuous and vigorous investment in technology research and development, we can steadily create more mature and reliable products. Building a trouble-free wind farm throughout the year is not only to promote Sany Renewable Energy, but also to promote the industry to improve standards and improve product reliability. ”

"With the construction of more and more 'trouble-free' wind farms, we also plan to study and actively obtain opportunities for the cooperation and development of overseas new energy projects, give full play to the advantages of all parties to go to sea, and promote the implementation of the 'going out' strategy of industrial cooperation." Zhao Jianyong said.

Adhering to the concept of "Intelligent Manufacturing Leads the Future" and the vision of "Promoting the Efficient Use of Clean Energy by Human Beings", Sany Renewable Energy is committed to building Sany Renewable Energy into the "Sany Heavy Industry" of the wind power industry, and contributing to China's realization of "carbon peaking and carbon neutrality" and the world's clean energy transformation.
