SAFETY SYSTEM FOR A WIND TURBINE

摘要

To safely operate a wind turbine, a control system may determine a current state of the wind turbine and identify whether the state is within an operational envelope. Based on measured sensor data, the control system may calculate the current state of the turbine in a multi-dimensional space where each axis of the multi-dimensional space correlates to one of the measured parameters. The boundary of the operational envelope may define a region of the multi-dimensional space where the wind turbine is behaving in a safe manner. A safety system may determine if the state determined by the control system is accurate. If so, the safety system determines whether the current state is within the operational envelope. If the state is outside the envelope, the wind turbine may switch to a safe state during which the turbine may be decoupled from the utility grid or the rotor is stopped.

1. A system for controlling a wind turbine, the system comprising:
a computing system communicatively coupled to the wind turbine, the computing system is configured to:
obtain sensor data comprising measured values of a plurality of parameters associated with the wind turbine, anddetermine, based on the obtained sensor data, a state of the wind turbine within a multi-dimensional space, where each axis in the multi-dimensional space corresponds to a respective one of the plurality of parameters; and a safety system configured to:
verify that the state identified by the computing system satisfies a threshold of accuracy, and upon verifying the state, determine whether the state is within a predefined operational envelope to determine safe operation of the wind turbine, the operational envelope encapsulating a region of the multi-dimensional space.
