金风科技获专利，从机舱加速度与转速识别风机共振时段

11月6日，金风科技（002202）的发明专利《风力发电机组的共振识别方法、控制器及风力发电机组》获授权，申请号为CN202210895085.9。

控制器把机舱加速度的连续记录划成许多相互移动的时间窗口，再根据各段统计量找出异常片段。结合发电机转速，系统据此判断哪些时间区间可能发生共振。方法需要的主要输入是机舱振动与转速，而不是额外布置一整套测量系统。专利的设计目标是在识别共振发生时间的同时控制运算成本。

截至此次授权消息披露时，金风科技今年获得的各类专利授权共95项，比上年同期增加14.46%。在2026年上半年，公司研发投入为10.46亿元，同比增长15.37%。企业知识产权记录中，金风科技股份有限公司名下可查到1816条专利信息和58条著作权信息。
