Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0041] Please refer to figure 1 , figure 1 It is a flow chart of a method for controlling crosswind yaw of a wind power generating set provided in an embodiment of the present application. The crosswind yaw control method of the wind generating set includes the following steps:

[0042] Step S1, when the rotational speed of the impeller exceeds the preset rotational speed limit, it is judged whether the blade is stuck.

[0043] Specifically, the rotational speed of the impeller i...

Abstract

The application discloses a crosswind yaw control method, system and related components of a wind power generating set. The crosswind yaw control method of a wind power generating set includes the following steps: when the speed of the impeller exceeds the preset speed limit, determine whether the blade is stuck ; If yes, then generate a crosswind yaw command, so as to control the impeller to swing in a preset direction at a preset angle. The crosswind yaw control method of the wind generator set provided by this application performs crosswind yaw operation when the wind generator set is overspeed and the blades are stuck, so as to avoid The speed continues to increase under certain conditions, which improves safety.

Description

technical field [0001] The present application relates to the technical field of wind power generation, and more specifically, to a crosswind yaw control method, system and related components of a wind power generating set. Background technique [0002] With the rapid development of the domestic wind power industry, variable-speed and variable-pitch wind turbines have become the mainstream. The speed control, as one of the most important controls of wind turbines, has always received strong attention. [0003] At present, wind turbines may overspeed under special working conditions. Under normal circumstances, after an overspeed fault is triggered by the wind turbine, the blades should be retracted to the stop position, and the turbine can stop normally. However, sometimes the blades will be stuck and cannot return to the propeller smoothly. At this time, if the wind turbine is facing the wind direction, the speed will continue to rise, which may easily lead to safety accid...
