D10000-185

Low Maintenance Costs

• Adopts a direct-drive technology path, eliminating the need for regular replacement of gear oil, filters, and generator brushes, reducing maintenance time.

• Fewer components in the unit result in lower failure rates, shorter scheduled downtime, and less energy loss.

• Fewer consumables required for maintenance, reducing overall maintenance costs.

• Electrical components (such as converters and transformers) are located at the tower base, making maintenance convenient.

• Inspection intervals extended to one year, reducing workload and minimizing energy loss.

Low Engineering Costs

• Compared to 7–8MW units, reduces the required number of installations by 25%–30%, lowering engineering costs by 800–1400 RMB/kW.

Superior Power Generation Performance

• Features a large rotor diameter of 185 meters with a single-unit capacity of 10.0MW, the largest rotor diameter in its power class.

• Over 60 years of experience in large-scale power equipment design and manufacturing, with generator efficiency 1%–3% higher than domestic counterparts.

• High-efficiency blade design utilizing advanced technologies such as serrated trailing edges and vortex generators, achieving a Cp value above 0.49.

• Proprietary control system perfectly matched with blades, maximizing energy capture while controlling loads.

• Medium-voltage IGCT solution offers higher efficiency than low-voltage systems, with a 1%–3% increase in generation efficiency.

High Safety and Reliability

• The direct-drive technology path has a shorter transmission chain and no high-speed rotating parts, enhancing reliability.

• No high-speed lubrication system or generator slip rings, reducing fire risk and improving safety.

• Dual-safety chain design with patented technology, eliminating overspeed incidents and further enhancing safety.

• Proprietary control system with an average mean time between failures (MTBF) of over 3000 hours.

• Patented magnet protection technology prevents demagnetization and detachment, with zero downtime for high-power direct-drive generators.

• Fully sealed structure to prevent salt spray corrosion, with forced internal convection and external air-to-air cooling for efficient heat dissipation.

• Active typhoon resistance strategy and backup power solution, capable of withstanding typhoon winds up to 77 m/s.

• Dual-circuit electrical system with multiple redundancies in control design, allowing independent operation of a single circuit.

• Dual-drive electric pitch technology reduces pitch bearing gear surface wear, extending the lifespan of the pitch bearing.

• Voltage level raised to 3150V, enhancing the safety of the twist cable system.
