Abstract
A control arrangement of a wind turbine includes a watchdog including a reset module and a trigger module, wherein the watchdog reset module is configured to perform an internal reset when a sign-of-life signal is received from a remote communication system within a predetermined time limit, and wherein the watchdog trigger module is configured to issue a watchdog trigger when the predetermined time limit is exceeded; a sensor arrangement including a number of sensors configured to observe local parameters and to report local sensor data; and a wind turbine controller that initiates a local control sequence in response to the watchdog trigger, which local control sequence is configured to switch between a first mode of operation and a second mode of operation on the basis of the local sensor data. A method of operating a wind turbine is further provided.
