Wind Turbine Hub Wireless Communication Solution

Wang Jun-gang

[Abstract]A pitch slip ring is generally used between the wind turbine nacelle and the hub to realize the electrical connection between the two. For grid-connected wind turbines, due to operational needs, if the corresponding channels need to be added, the traditional solution may be limited. In view of this situation, this paper proposes an effective solution.

1 风力发电机组机舱柜与变桨柜传统的电气连接方式

目前大多数公司风力发电机组的机舱柜(静止部分)与变桨柜(安装在轮毂中,正常工作时随同轮毂一起转动)之间,均采用单一的变桨滑环来进行电气连接。(剩余2753字)
