Abstract: A method for preventing catastrophic damage in a drivetrain of a wind turbine includes receiving, via a controller, a speed measurement of the generator of the drivetrain. The method also includes determining an electrical torque of a generator of the drivetrain of the wind turbine. The method further includes estimating, via the controller, a mechanical torque of the rotor as a function of at least one of the electrical torque and the speed measurement of the generator. Further, the method includes comparing, via the controller, the estimated mechanical torque to an implausible torque threshold, wherein torque values above the implausible torque threshold speed values greater that the implausible speed threshold. Moreover, the method includes implementing, via the controller, a control action for the wind turbine when the estimated mechanical torque exceeds the implausible torque threshold.

Abstract: The present disclosure is directed to a system and method for balancing reactive power loading between multiple renewable energy power systems coupled to a power grid at a point of regulation (POR). The method includes determining a voltage error based on a voltage reference and a measured voltage at the POR. The method also includes measuring at least one operating condition from each of the power systems. Further, the method includes determining a per unit actual reactive power for each of the power systems based on at least one of the actual operating conditions and determining a per unit average reactive power from the power systems based on at least one of the actual operating conditions. Thus, the method also includes determining a voltage reference command for each of the power systems as a function of the voltage error, the per unit reactive power, and/or the per unit average reactive power.

Abstract: The present subject matter is directed to a system and method for improving speed control of a pitch drive system of a wind turbine. In one embodiment, the pitch drive system includes a direct current (DC) motor having an armature and a series-field winding, a battery assembly having a positive terminal and a negative terminal, and a current-controlling device configured in series between the positive terminal of the battery assembly and the series-field winding. The battery assembly is configured to supply power to the pitch drive system and the current-controlling device is configured to supply current to the series-field winding so as to ensure a field flux does not equal zero. Thus, the current-controlling device has the effect of limiting the maximum speed of the DC motor.

Abstract: The present disclosure is directed to a system and method for protecting a rotary machine in a high noise environment. In one embodiment, the method includes a step of measuring a vibration signal during operation of the rotary machine. Another step includes modulating the vibration signal at a desired frequency to generate a modulated signal having a direct current (DC) value. The desired frequency varies as a function of an operational parameter of the rotary machine. The method also includes a step of filtering the modulated signal via one or more low-pass filters. Another step includes comparing an amplitude of the filtered signal to a threshold amplitude for one or more components of the rotary machine. The threshold amplitude is indicative of an imbalance within one or more components of the rotary machine. The rotary machine is then operated based on the comparison so as to protect the rotary machine from damage caused by the imbalance within the one or more components of the rotary machine.
