Abstract

The present invention provides a flow guiding device of a wind power generator set and its control method, and a wind power generating set. The flow guiding device includes a wind guiding screen and a stay cable. The first end of the stay cable is fixed to the tower of the wind power generator set. The second end of the stay cable is fixed to the ground, and the wind guide screen is arranged between two adjacent stay cables to form a guide surface inclined relative to the vertical direction. According to the flow guide device and control method of the wind power generator set and the wind power generator set of the present invention, the flow field around the wind power generator set can be changed, the wind speed actually flowing through the impeller can be increased, and the power generation can be increased.

Description

technical field [0001] The invention relates to a flow guide device of a wind power generator set, a control method for the flow guide device of the wind power generator set and a wind power generator set including the flow guide device. Background technique [0002] In large-scale wind turbines, in order to save the tower material of the wind turbine and reduce the tower manufacturing cost and transportation cost, a narrower tower can be used, and a stay cable structure can be set on the tower, for example, as figure 1 As shown, the tower is fixed to the ground by three multi-strand steel wire ropes at a certain angle with the vertical direction, thereby reducing the moment and load between the bottom of the tower and the ground, and improving the stability of the tower. [0003] However, in the wind power generating set with this structure, due to the limitation of the wire ropes, the swept area of ​​the blades may be small, which affects the power generation of the wind p...
