摘要： The invention provides a method of determining tower top acceleration of a wind turbine. The method includes receiving acceleration data from a plurality of acceleration sensors positioned in a nacelle of the wind turbine, including data indicative of a measured acceleration in a direction along at least one measurement axis of each respective acceleration sensor at a current time step. The method includes determining a predicted tower top acceleration of the wind turbine tower at the current time step, the predicted tower top acceleration being determined in dependence on a kinematic model of the wind turbine, and on a determined estimation of tower top acceleration at a previous time step. The method includes determining an estimated tower top acceleration of the wind turbine tower at the current time step by updating the predicted tower top acceleration based on the measured acceleration from each of the acceleration sensors.

摘要： A fluid-turbine system, method and apparatus optimizes wind-turbine performance by use of sensors embedded on a shroud and/or ejector shroud. The sensors monitor visible or audible movement, vibration, acoustic waves or temperature. A combination of sensors and monitoring means comprises a method for preventing or mitigating the negative effects of dormant failure.
