SYSTEM AND METHOD FOR UPGRADING WIND TURBINES FROM DIFFERENT SUPPLIERS

摘要

The present disclosure is directed to a system and method for controlling and/or upgrading aftermarket multivendor wind turbines. The system includes a turbine controller 26 configured to control operations of the wind turbine 10, a safety device 104 configured to provide a signal indicative of a health status of the safety device 104, and a secondary controller 102 inserted between the safety device 104 and the turbine controller 26. The secondary controller 102 is configured to receive the signal from the safety device 104 over a communication interface. As such, if the signal indicates a normal health status, the secondary controller 26 is configured to send the signal to the turbine controller 26, i.e. maintain normal operation. Alternatively, if the signal indicates a poor health status, the secondary controller 102 is configured to adjust the signal based at least in part on a signal bias to an adjusted signal and to provide the adjusted signal to the turbine controller 26.
