Classification: CPC F  Y | IPC F

Claim 19:
20. A computer program product comprising software code adapted to control a wind turbine when executed on a data processing system, the computer program product being adapted to perform an operation of monitoring a wind turbine, the wind turbine comprising a tower and a first and a second arm extending from the tower, each arm carrying a respective rotor-nacelle assembly, the operation comprising:
generating first movement data based on movement of the first arm or of a first rotor-nacelle assembly of the wind turbine by a first movement sensor;
generating second movement data based on movement of the second arm or of a second rotor-nacelle assembly of the wind turbine by a second movement sensor, wherein a control system of the wind turbine comprises a time synchronous network and the first and second movement sensors are configured to be time synchronous with at least one of each other or the control system, the control system is arranged to receive and process the first and second movement data; and
calculating latency within the time synchronous network to make adjustments for time differences of the first and second movement data received to determine an oscillation characteristic of the wind turbine based on the first and the second movement data.
