Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] For the yaw device, the conventional control method is mostly used at present, and the yaw is controlled by collecting commonly used control quantities such as wind direction and button switch on the hardware, but this method cannot fully collect signals, so that the yaw control cannot be accurately performed, and then in In the process of yaw control, it is easy to make the yaw load t...

Abstract

The invention provides a yaw control method and device, electronic equipment and a storage medium. The method comprises the steps that when wind direction changes are detected, a hydraulic brake is controlled to be released if a yaw overload protection state of a wind driven generator meets a preset condition; after the hydraulic brake is released, if the yaw pressure is smaller than a first threshold value, a yaw motor is controlled to start yaw; and after the yaw motor starts yaw, if the yaw current is larger than a second threshold value, the yaw motor is controlled to stop yaw. Therefore, whether a yaw system needs pressure relief or not can be rapidly and accurately judged based on the yaw pressure, and the yaw motor is controlled to start yaw; and on the basis of the yaw current, the yaw load condition can be judged in advance, the yaw motor is controlled to stop yaw, and therefore yaw system faults caused by tripping under special working conditions are avoided, and the manual operation and maintenance cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, in particular to a yaw control method, device, electronic equipment and storage medium. Background technique [0002] Wind power refers to converting the kinetic energy of wind into electrical energy. The principle of wind power generation is to use the wind to drive the windmill blades to rotate, and then increase the speed of rotation through the speed increaser to promote the generator to generate electricity. [0003] Wind turbines include nacelle, rotor blades, shafts, gearboxes, generators, yaw devices, and hydraulic systems. Among them, the yaw device is used to turn the nacelle by means of an electric motor to control the rotor to face the wind. For the yaw device, conventional control methods are mostly used at present. The hardware relies on collecting common control quantities such as wind direction and torsion cable switch to control the yaw. However, this meth...
