Power class: 2.5 MW

Diameter of blades: 103 m, 107 m, 125 m, 140 m, and 147 m

Height of towers: 80 m, 85 m, 90 m, 120 m, 140 m, and 160 m

Technical features: 2.5MW series wind turbines are constructed of mature and reliable upwind direction, horizontal axis, three-point support structure and adopt the variable-speed constant-frequency double-fed power generation technology. They are designed and developed by Windey in view of the characteristics of wind resources and environment in mountainous areas exposed to a low wind speed.

Technical features: 2.5MW series wind turbines are constructed of mature and reliable upwind direction, horizontal axis, three-point support structure and adopt the variable-speed constant-frequency double-fed power generation technology. They are designed and developed by Windey in view of the characteristics of wind resources and environment in mountainous areas exposed to a low wind speed；the overall design of the wind turbine is reasonable, which allows modular transportation and lifting in areas with a complex terrain where the transportation and installation conditions are very unfavorable. The ergonomic design of nacelle makes it easy for O&M personnel to enter and leave, thus shortening the maintenance time；the internationally popular and mature gearbox design contributes to a high power generation efficiency. In addition, the load optimization and control scheme with independent intellectual property rights is adopted, which effectively reduces the load, prolongs the service life and improves the reliability of wind turbine；components are customized based on the environment, thereby enhancing the environmental adaptability of wind turbine. The pitch system is of a maintenance-free design, and a super-capacitor is used as the standby power supply, thus reducing the maintenance costs；the wind turbine has low voltage, zero voltage and high voltage ride-through capability above the international standard. It takes the lead in passing the primary frequency modulation inertia response test, can actively participate in peak regulation and frequency modulation of the power grid to meet the requirements for integration of distributed wind power to the grid.
