    Abstract: The invention provides a computer-implemented method of controlling operation of a wind turbine in which a plurality of wind turbine zones are defined. The method comprises, for each of the plurality of wind turbine zones: receiving sensor data from at least one electromagnetic radiation sensor arranged to monitor the respective wind turbine zone; and, determining, based on the received sensor data, whether one or more people are in the respective wind turbine zone. The method comprises selecting an operational mode of the wind turbine based on the determination as to which of the plurality of zones have one or more people therein, and controlling the wind turbine to operate in the selected operational mode.

    Abstract: Embodiments herein describe validating an emergency stop signal before activating a brake within a wind turbine. The emergency stop signal is received from a control node of a plurality of control nodes distributed throughout the wind turbine, and the emergency stop signal indicates that the wind turbine should be shut down. The wind turbine is shut down by transmitting a shutdown signal to the plurality of control nodes. Upon determining there is no indication a person is present within the wind turbine, the emergency stop signal is validated. Additionally, upon determining the emergency stop signal is valid, a brake within the wind turbine is activated to bring the rotor to a stop.
