摘要： A lift system for a rotor blade of a wind turbine includes a lifting device having a structural frame body having a root end and a tip end. The root end supports a root cradle and the tip end supports a tip cradle. The root and tip cradles each have a profile that corresponds to at least one exterior surface of the rotor blade so as to receive and support at least a portion of the rotor blade. Due to a shape of the rotor blade, when the rotor blade is installed in the lifting device and lifted uptower, the rotor blade can experience an asymmetric loading. Accordingly, the lift system also includes a variable airflow assembly coupled to tip end of the lifting device. The variable airflow assembly includes at least one surface moveable between a plurality of positions having varying resistances so as to counteract the asymmetric loading.

摘要： A system and method for preventing a rotor blade from striking a tower of the wind turbine is disclosed. The system includes a pitch adjustment mechanism, at least one electrical switch, and a mechanically-actuated positional switch. The pitch adjustment mechanism is configured to rotate the rotor blade about a pitch axis. Further, the pitch adjustment mechanism includes a motor and a brake. The electrical switch is configured with the motor, the brake, or both. The mechanically-actuated positional switch is fixed within a hub of the wind turbine. Further, the positional switch is configured with the electrical switch such that if the rotor blade rotates to an unsafe region, the positional switch is configured to trigger the electrical switch to implement one of tripping power to the motor of the pitch adjustment mechanism or actuating the brake of the pitch adjustment mechanism.

摘要： A system for controlling a wind turbine may include at least one sensor configured to provide at least one of a wind speed signal or a wind direction signal and a turbine controller configured to control the operation of the wind turbine. The system may also include a secondary controller inserted between the sensor(s) and the turbine controller. The secondary controller may be separated from the turbine controller by a distance and may be configured to receive the wind speed signal and/or the wind direction signal from the sensor(s) over a communication interface. In addition, the secondary controller may be configured to adjust the wind speed signal and/or wind direction signal based at least in part on a signal bias value(s) to an adjusted signal(s) and to provide the adjusted signal(s) to the turbine controller.

摘要： Systems and methods for controlling a wind turbine based on sensor readings are provided. A signal path between a sensor and a turbine controller can be modified and a secondary controller can be inserted between the turbine controller and the sensor. The secondary controller can receive a signal from the sensor and adjust the signal to an adjusted signal. The adjusted signal can be communicated to the turbine controller which can control operation of the wind turbine based at least in part on the adjusted signal. In this way, the operation of the wind turbine based on various sensor readings can be adjusted to provide for increased energy production without requiring access to computer-readable instructions, such as source code, implemented by the wind turbine controller.

摘要： A trip reduction tool for a wind turbine power system includes a capacitor assembly configured to provide multiple capacitance levels for the power system, including e.g. a first level of capacitance during a learning phase of the tool. The tool also includes one or more processors communicatively coupled to the capacitor assembly that is configured to monitor a plurality of electrical devices of the power system for trips during the learning phase. When a trip is detected, the processor(s) collects data and determines a location of the trip. When the location of the trip is located in an electrical device that corresponds to a weak link of the power system, the processor(s) determines a second level of capacitance for the power system based on the collected data. In addition, the processor(s) provides the second level of capacitance at the weak link of the power system to reduce future trips of the electrical device.
