Abstract
The present invention relates to a fault-tolerant control system for a wind turbine comprising a plurality of controllable wind turbine components, the control system comprising control means for generating a replica of essentially concurrent set-point values, a data communication network for transmitting the replica of essentially concurrent set-point values to the plurality of wind turbine components, and a plurality of decentralized voting means being arranged so that a decentralized voting means is assigned to each wind turbine component, each decentralized voting means being adapted to select one set-point value out of the replica of set-point values. The present invention further relates to a wind turbine and to an associated method.
