Abstract

The invention belongs to the technical field of wind power generation, and particularly discloses a vortex-induced vibration monitoring system based on radio ranging and an installation method thereof. The vortex-induced vibration monitoring system comprises a wind driven generator, radio transmitting devices and radio receiving devices, wherein four radio transmitting devices are arranged at the same height of the top of the wind driven generator at intervals of 90 degrees; and two radio receiving devices are arranged at the same height as the tower bottom of the wind driven generator. According to the invention, the effectiveness of the vortex-induced vibration suppression device is verified by monitoring a horizontal distance between the radio transmitting devices and the radio receiving devices; the working condition data of a wind generating set are collected through a wind generating set data collector, the height of a tower drum when vortex-induced vibration occurs is measured and calculated, hoisting at the height is avoided, and therefore, the probability of vortex-induced vibration occurrence is reduced, hoisting delay caused by vortex-induced vibration is avoided, and hoisting cost is reduced; and meanwhile, the damage of vortex-induced vibration to the set can be prevented through the system.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a radio ranging-based vortex-induced vibration monitoring system and an installation method. Background technique [0002] Vortex-induced vibration is a serious problem in the hoisting process of wind turbines, which will lead to prolonged hoisting time of the unit, resulting in economic losses and the possibility of safety accidents. In the development of the vortex-induced vibration suppression device, the spoiler device is prominent and widely used, and the core functional part of the spoiler device is the spoiler block or the spoiler bar. The spoiler block or spoiler strip is attached to the surface of the tower through its own geometric characteristics, effectively controlling the separation position of the vortex, so as to achieve the effect of destroying the entire original regular flow field. [0003] According to the existing tower hoisting pro...
