摘要： A method for initializing startup of a wind turbine includes measuring a first wind condition at the wind turbine at a first moment in time. The method also includes measuring a second wind condition at the wind turbine at a subsequent, second moment in time. Further, the method includes estimating an acceleration parameter of the wind turbine as a function of the first wind condition and the second wind condition. Moreover, the method includes comparing the acceleration parameter to a predetermined threshold. As such, the method includes initializing a first startup process for the wind turbine when the acceleration parameter is at or below a predetermined threshold. Further, the method includes initializing a second startup process for the wind turbine when the acceleration parameter exceeds a predetermined threshold, the second startup process being faster than the first startup process.

摘要： A method for reducing loads of a wind turbine includes determining an angular pitch speed parameter of the rotor blade of the wind turbine. The method also includes determining an operational state of the wind turbine. Further, the method includes comparing the angular pitch speed parameter to a predetermined parameter threshold during turbine shutdown and/or a commanded pitch event. If the operational state corresponds to a predetermined operational state, the method includes yawing a nacelle of the wind turbine away from an incoming wind direction when the angular pitch speed parameter is below the predetermined parameter threshold during the turbine shutdown and/or the commanded pitch event.

摘要： 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.

摘要： Systems and methods for preventing excessive loading on a wind turbine are disclosed. The method includes determining a current wind turbine parameter using at least one operating condition via a processor, the operating condition indicative of wind turbine operation; storing the current wind turbine parameter in a memory store over a predetermined time period; calculating a standard deviation of a plurality of the stored current wind turbine parameters; determining a future wind turbine parameter; calculating a maximum wind turbine parameter as a function of the standard deviation of the plurality of stored wind turbine parameters and the future wind turbine parameter; and, controlling the wind turbine based on a difference between the maximum wind turbine parameter and a parameter setpoint to prevent excessive loading from acting on the wind turbine.

摘要： A control system for a wind turbine includes a detecting system configured to determine at least one of a rotor load, a wind shear, a wind speed, and a load imbalance due to wind shear. An adjusting system is configured to adjust a shaft moment set point correction value based on at least one of the rotor load, the wind shear, the wind speed, and the load imbalance. A compensating system is configured to compute a shaft moment correction command based on the shaft moment set point correction value output from the adjusting system. A pitch system is configured to adjust a pitch of at least one blade of the wind turbine based on the shaft moment set point correction command, or a yaw system is configured to adjust the yaw position of a rotor based on the shaft moment set point correction command.

摘要： A system and method are provided for managing flicker generated by a wind farm. Accordingly, the farm controller detects at least one parameter of the wind farm indicative of an output flicker resulting from a synchronized flicker of at least two turbines of the plurality of wind turbines. Upon detecting the parameter, the farm controller generates a command offset for at least one wind turbine of the at least two wind turbines. An operating parameter of the at least one wind turbine is changed based on the command offset so as to de-synchronize the synchronized flicker in the output signals of the at least two wind turbines.

摘要： Power generation stabilization control systems and methods include monitoring a frequency of the power grid. In response to detecting a frequency event occurring in the power grid, the method includes activating a control scheme in order to meet one or more grid requirements of the power grid. The control scheme includes increasing a power output of the wind turbine to, at least, a pre-event measured grid power. Further, the control scheme includes calculating a power correction factor for a power set point as a function of, at least, the frequency event. Moreover, the control scheme includes adjusting the power set point via the power correction factor such that the power output follows a predetermined trajectory. In addition, the control scheme includes controlling, via a turbine controller, the wind turbine based on the adjusted power set point for as long as the control scheme is activated.

摘要： A method for operating a wind turbine during partial load operation includes determining a power output of the wind turbine. The method also includes determining whether the power output is below a rated power of the wind turbine. If the power output is at the rated power, the method includes maintaining a speed set point of the wind turbine equal to a rated speed set point. However, if the power output is below the rated power, then the method includes varying, via a controller, the speed set point of the wind turbine as a function of a torque of the wind turbine in a non-monotonic torque-speed relationship.
