Abstract

The invention provides a wind turbine generator cable loosening control method, device and equipment and a wind turbine generator. The method comprises the steps of predicting cable loosening data of the wind turbine generator in a target time period; according to the cable untwisting data, the cable twisting advance of the wind turbine generator is determined; according to the cable twisting advance, the cable of the wind turbine generator is unwound in advance, and the cable is unwound in advance by determining the cable twisting advance in advance, so that the cable unwinding frequency of the wind turbine generator can be effectively reduced, the power generation amount of the wind turbine generator is increased, and the power generation efficiency is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of wind turbine uncable control, in particular to a wind turbine uncable control method, device, equipment and wind turbine. Background technique [0002] Wind turbines (referred to as: wind turbines) will be in a state of continuous cable twisting during actual operation. Changes in the wind direction may cause the twisted cable angle of the wind turbine to continue to increase. The twisted cable angle at a large angle for a long time may be harmful The power cables have some influence, and may even affect the safe operation of the wind turbine. The traditional software twisting cable protection method mostly determines the reverse untwisting angle value of the wind turbine according to the current twisting angle value of the power cable, and then performs cable untwisting control. [0003] However, the twisting protection method of untwisting the cable after the cable is twisted to a preset angle ...
