March 24 News: According to the State Intellectual Property Office, Yunda Energy Technology Group Co., Ltd. has applied for a patent titled “Method, Device, Equipment, and Storage Medium for Determining Anti-typhoon Performance of Yaw Motors.” The application publication number is CN121676279A, the application number is CN202511873248.3, the publication date is March 17, 2026, and the application date is December 12, 2025. The inventors are Li Ya, Gao Liqun, Lou Yufang, Zhang Wei, and Huang He’ao. The patent agency is Beijing Jiajia Intellectual Property Agency Co., Ltd., with patent agent Wang Yuwei. The classification codes are F03D17/00, G01R31/34, G01D21/02.

Patent Abstract: The invention discloses a method, device, equipment, and storage medium for determining the anti-typhoon performance of yaw motors, applied in the wind turbine field. It determines the startup performance of the yaw motor based on its rated torque and startup multiple; calculates the maximum system equivalent wind load based on the gear ratio of the yaw reducer, gear ratio between large and small gears of the yaw system, and maximum wind load; obtains the initial and final temperatures of the yaw motor before and after anti-typhoon testing to determine the temperature rise. When the startup performance exceeds the maximum system equivalent wind load and the temperature rise is below the motor insulation temperature, the yaw motor is considered to meet active anti-typhoon performance. When the braking performance exceeds the maximum system equivalent wind load, it is considered to meet braking anti-typhoon performance. The invention proposes a precise method for evaluating the anti-typhoon performance of yaw motors, avoiding issues such as high material costs caused by excessive safety redundancy and the inaccuracy of performance determination results that could lead to safety accidents.
