Patent ID: 11913431
Assignee: VESTAS WIND SYSTEMS A/S
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC F  Y | IPC F

Claim 0:
1. A wind turbine comprising:
a tower;
a first arm extending from the tower;
a first rotor-nacelle assembly disposed on the first arm;
a first movement sensor disposed on the first arm or on the first rotor-nacelle assembly and arranged to generate first movement data based on movement of the first arm or of the first rotor-nacelle assembly;
a second arm extending from the tower;
a second rotor-nacelle assembly disposed on the second arm;
a second movement sensor disposed on the second arm or on the second rotor-nacelle assembly and arranged to generate second movement data based on movement of the second arm or of the second rotor-nacelle assembly; and
a control system coupled to the first and the second movement sensors and arranged to receive and to process the first and second movement data,
wherein the control system 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, and
wherein the control system is arranged to calculate 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 from the first and the second movement data.
