1. A system for controlling a wind turbine, comprising:

  • a turbine controller configured to control operations of the wind turbine;

    a safety device configured to provide an initial signal indicative of a health status of the safety device;

    a secondary controller inserted between the safety device and the turbine controller, the secondary controller being programmed with an existing braking procedure of the wind turbine, the secondary controller configured to receive the initial signal from the safety device over a communication interface;

    wherein, if the initial signal indicates a normal health status, the secondary controller is configured to send the initial signal to the turbine controller, andwherein, if the initial signal indicates a poor health status, the secondary controller is configured to;

    adjust the initial signal based at least in part on a signal bias to an adjusted signal, the adjusted signal comprising an updated braking procedure for the wind turbine; and

    provide the adjusted signal to the turbine controller.
