毕马威：跨国企业对中国经济前景及自身在华业务表现更加乐观金风科技获专利，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。
