Disclosed are a conductive ring assembly, a conductive device and a wind turbine. The conductive ring assembly includes a sun gear, a ring gear and one or more planet gear. The sun gear is located in the ring gear, and the sun gear and the ring gear are coaxially arranged. The one or more planet gear is engaged between the sun gear and the ring gear. The planet gear is conducted with the sun gear and the ring gear at the same time, so that an electrical signal is transmitted between the sun gear and the ring gear by means of the one or more planet gear. The conductive ring assembly uses a planet gear structure for communication data transmission to improve the interference resistance of the conductive ring assembly.

Conductive ring assembly, conductive device and wind turbine

A start control method for wind turbines (), comprising: a master control determines whether its real-time wind speed reaches a preset start wind speed when a wind speed of at least one wind turbine () or anemometer tower in a wind farm reaches or exceeds the preset start wind speed; the master controller updates a corresponding number simulative start times when determining that its real-time wind speed reaches or exceeds the preset start wind speed, and starts the wind turbine () when the number of simulative start times reaches a preset count value. The present invention also relates to a master controller, a system, and a central controller for wind turbines ().

Control method, master controller, system, and central controller for wind turbines

A wind turbine and an operational control method therefor are disclosed. The method comprises: obtaining current directional data from the nacelle of the wind turbine; and, according to the directional data, positional data of each wind turbine of a wind farm, as well as wind condition data as measured by each wind turbine, and controlling operational equipment of the wind turbine, so as to increase power generated by the wind turbine. According to the current direction of the nacelle of the wind turbine, positional data of each wind turbine of a wind farm, and wind condition data as measured by each wind turbine, accurate control policy adjustment is performed in advance on operational equipment of a wind turbine, thereby increasing the power generated by the wind turbine. A device for implementing the control method is also disclosed.
