Development of The Electro-hydraulic Control Technology for Wind Turbine

Key Technology and Achievements：

• The system structure and control algorithm of Digital Intelligent Soft Brake are proposed. Electro-hydraulic pitch-controlled system and soft brake system are developed.

• Pitch control and soft brake technology in wind turbine were studied at the earliest in China. The technology is already applied in wind turbine and approved by wind turbine plants and users.

• Developed pitch-controlled wind turbine semi-physical test-bed for enterprise, which can simulate all operating conditions and verify the whole wind turbine as well as key components.

• 3 authorized patents of invention and more than 20 SCI/EI articles are published.
