This technology relates to a control method for low-carbon renewable energy wind turbines that involves setting the braking initiation voltage and maximum braking force, checking the rectified voltage, and performing stepwise and continuous braking.
Conventional wind turbines have had issues with blades over-rotating during strong winds or squalls, leading to damage to components and reduced durability.
To address this, this technology detects the rectified voltage generated by blade rotation, initiating and maintaining braking in a stepwise manner. It also prevents over-rotation using a brake and pitch system, thereby increasing power generation efficiency through smooth operation and component protection.
