Boland - Model 7.x MW Series -Wind Turbine Generators

7.xMW series WTGS are brand-new onshore ultra-high-power intelligent WTGS.Following the mature doubly-fed technology route makes WTGS have higher reliability;Desert-type complete WTGS have environmental adaptability;excellent power generation performance and lower cost create greater value for customs.

Integrated design of the complete WTGS to improve the performance of the WTGS

Through the load efficient design technology,the optimal matching of the blade,complete WTGS and tower is carried out to achieve high matching of WTGS performance.

Desertification design to enhance environmental adaptability

1. The design of desertification environment adaptability enhances the adaptability of the WTGS to corrosion,high temperature,sandstorm and ultraviolet light.
2. Based on the big data collaborative control platform,early warning of sandstorms is realized to improve the operation and maintenance efficiency of wind farms.

Flexible split design,reducing the cost of the complete machine

1. Through modular design technology,the flexible design of each system of the complete machine is realized,which greatly reduces the transportation and hoisting cost.
2. Through platform design,the components of different models are highly shared,greatly reducing the design cost and O&M cost of the complete machine.

1) 7.xMW Series Wind Turbine For Biggest Electrical Generate With Lowest Cost

1. Use of large-capacity units can reduce the use of land resources
2. Reduce the cost of power plants and save investment costs
3. High unit efficiency, high thermal efficiency
4. Reduce power plant operating costs and improve economic efficiency
5. Can reduce the number of installed units and facilitate centralized control and management
6. Accelerate the speed of power construction and adapt to the rapidly growing load requirements.
