Abstract: The present subject matter is directed to a method for estimating rotor blade loads, e.g. a blade root resultant moment, of a wind turbine. In one embodiment, the method includes measuring, via one or more sensors, a plurality of operating parameters of the wind turbine. Another step includes estimating out-of-plane and in-plane forces acting on the rotor blade based at least partially on the plurality of operating parameters. Further, the method includes determining an application point for the out-of-plane and in-plane forces along a span of the rotor blade. A further step includes estimating out-of-plane and in-plane moments of the rotor blade based at least partially on the out-of-plane and in-plane forces and the respective application points. Thus, the method includes calculating the load acting on the rotor blade based at least partially on the out-of-plane and in-plane moments.

Abstract translation: 本主题涉及用于估计转子叶片负载的方法，例如， 风力涡轮机的叶片根结合力矩。 在一个实施例中，该方法包括经由一个或多个传感器测量风力涡轮机的多个操作参数。 另一步骤包括至少部分地基于多个操作参数估计作用在转子叶片上的平面外面和面内力。 此外，该方法包括确定沿着转子叶片跨度的平面外面和面内力的应用点。 另外的步骤包括至少部分地基于平面外和平面内的力以及相应的应用点来估计转子叶片的平面外面和平面内的力矩。 因此，该方法包括至少部分地基于平面外和平面内的力矩计算作用在转子叶片上的载荷。
