Abstract
The invention relates to the technical field of high-altitude wind power, in particular to a multi-roller cable winding method for high-altitude wind power. The method comprises the steps that the tension of a cable before entering a roller is obtained; the number and the winding mode of the cable winding rollers are changed, and the number of the rollers, the envelope angle and the equivalent friction coefficient after each time of change are determined; wherein the equivalent friction coefficient is a variable related to the winding mode of the cable and the tension of the cable; the optimal winding mode of the multi-roller cable is determined based on the tension before the cable enters the rollers, the number of the rollers, the envelope angle and the equivalent friction coefficient; wherein at least part of the rollers are wound with a turn of cable rope, so that the cable rope can drive the rollers to rotate under the driving of the umbrella group, and the number of the rollers which are wound with the cable rope and can drive the planetary gear to rotate is not less than three. According to the technical scheme, the load transmission capacity and the energy transmission efficiency can be improved at the same time.
