Abstract: A method of estimating an amount of undesired loading experienced by at least a portion of a structure (100) is provided. The structure (100) may be, for example, a wind turbine generator (WTG) and the portion for which undesired loading is estimated may be, for example, a rotor (130) of the WTG. The method includes receiving a first signal characterizing instantaneous stress experienced by a component (140) of the structure (100) and filtering out at least a portion of the received first signal that corresponds to the desired loading experienced by the component to produce a first filtered signal. The amount of undesired loading experienced by the at least a portion of the structure (100) is estimated based at least partially on the first filtered signal.

Abstract translation: 提供了一种估计由结构（100）的至少一部分经历的不希望的加载量的方法。 结构（100）可以是例如风力涡轮发电机（WTG），并且估计不期望负载的部分可以是例如WTG的转子（130）。 所述方法包括接收表征由所述结构（100）的组件（140）经历的瞬时应力的第一信号，并且过滤所接收到的所述第一信号的至少一部分，所述第一信号对应于由所述组件经历的期望负载以产生第一滤波 信号。 至少部分地基于第一滤波信号来估计结构（100）的至少一部分所经历的不需要的负载量。
