On June 7, 2022, the first batch of large-scale wind power photovoltaic base projects in the country and the landmark project of the Yalong River Basin water-wind-solar hybrid green and clean renewable energy demonstration base - the Laba Mountain Wind Power Project officially started construction.

According to reports, the Laba Mountain Wind Power Project is located in Dechang County, Liangshan Prefecture, with an installed capacity of 192,000 kilowatts. It is planned to build 60 wind turbines. The fans are distributed in the north, middle and west sides of the main ridge of Laba Mountain along the extended branch of the Yalong River Valley. The Laba Mountain Wind Power Project plans to hoist the first unit in October 2022, and all units will be put into operation in September 2023.

After completion, the annual power generation will exceed 500 million kWh

Since the 14th Five-Year Plan, Sichuan Province has approved a number of wind power projects, and the largest one has been started construction is the Laba Mountain Wind Power Project, which has an equivalent annual utilization hours of 2,612 hours. It can provide about 501 million kWh of clean electricity for Sichuan, which can meet the annual electricity consumption of about 210,000 households. The annual electricity output can save about 160,000 tons of standard coal and reduce carbon dioxide emissions by about 400,000 tons. It is of great significance to achieve the goal of energy conservation and emission reduction and promote the coordinated development of the Chengdu-Chongqing economic circle. It marks the national large-scale wind power photovoltaic base. Project construction is progressing steadily in Sichuan.

On the other hand, the Laba Mountain Wind Power Project is the first wind power project to be constructed in the Yalong River Basin Clean Energy Base since the 14th Five-Year Plan. In March 2021, the National Fourteenth Five-Year Plan and the 2035 Vision Outline clearly proposed to build the Yalong River Basin Clean Energy Base, which is one of the nine clean energy bases in China.

According to the introduction of the relevant person in charge of Yalong River Basin Hydropower Development Co., Ltd., according to the national plan, the Yalong River Basin Water-Wind-Wind Hybrid Green and Clean Renewable Energy Demonstration Base has a total scale of over 80 million kilowatts, of which wind power, photovoltaic power generation exceeds 40 million kilowatts, Pumped storage power generation exceeds 10 million kilowatts. After completion, it will become one of the largest green and clean renewable energy bases in the world.

High Altitude Mountain Wind Farm

On the whole, the Laba Mountain project has a short construction period and is located in a high mountain and canyon area. Labashan Wind Farm has 60 fans, the impeller diameter is 172 meters, the tower is 110 meters high, and the construction road stretches for more than 80 kilometers. The transportation and installation of mechanical and electrical equipment, construction materials and equipment have become difficult problems. At the same time, the site area is high in altitude and is greatly affected by bad weather, which requires high reliability of equipment. The construction environment of the project is open, and the construction area is mostly located in the forest area, and the pressure of forest fire prevention and control is high.

The relevant person in charge of Yalong River Basin Hydropower Development Co., Ltd. said that intelligent construction will be the starting point to build a new generation of full-life cycle digital intelligent high-altitude mountain wind farms. Based on the innovation and application of the closed-loop control concept based on the cloud-edge synergy mode, Labashan Wind Farm will maximize the power generation potential of the units, and strive to build a new generation of wind power intelligent control system, which will increase the power generation by more than 5%.

At the same time, the multi-dimensional assessment of the unit health is carried out to provide the best decision-making scheme for the operation and maintenance of wind farm units, and through the multi-angle control of wake, interval crossing, sector, rain erosion, life extension, etc., to achieve the balance between power generation and unit health. balance. Use data to drive the intelligent operation and maintenance and refinement of operation management of wind farms, and realize the leap from passive operation and maintenance to active operation and maintenance to appointment operation and maintenance. Through the algorithm model and the closed-loop mechanism of wind farm management and control, we strive to make the wind farm unattended. By creating higher-quality and more intelligent wind turbine equipment, it provides core support for the project to become a world-class wind farm with advanced technology, intelligent operation and maintenance, grid-friendly and ecological harmony.

Helping rural revitalization in ethnic areas

It is reported that the construction of the Laba Mountain Wind Power Project will further help the rural revitalization in ethnic areas and promote local economic and social development.

Liangshan Prefecture is the largest wind power base in Sichuan and an important clean energy industry base in Southwest China. As a landmark project for the acceleration of wind power development in Liangshan Prefecture, the construction of the Laba Mountain Wind Power Project marks another step forward in the construction of a national-level clean energy industry base in Liangshan. The construction of the project will effectively drive the development of local industries and social progress, and form an important economic radiation point, which is of great significance for consolidating the achievements of poverty alleviation and promoting rural revitalization.

The total investment of the Labashan Wind Farm exceeds 1.5 billion yuan. During the construction period, it will contribute about 60 million yuan in taxes and fees to Liangshan Prefecture's finances and provide more than 1,000 jobs for Liangshan Prefecture. After the project is fully put into operation, it can continue to contribute about 40 million yuan in taxes and fees to Liangshan Prefecture every year. Editor/He Yuting
