Embodiment Construction

[0024] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0025] As a key part of wind turbines to capture wind energy, the health of blades directly affects the operation of the entire wind power system. The blades of wind power generation equipment are generally very long, and during operation, various parts will deform to varying degrees under the action of wind. Moreover, as the operating time of the blades increases, the fatigue damage of the blades will gradually increase. The accum...

Abstract

The invention discloses a system for monitoring blade deformation of wind power generation equipment, comprising at least one stay wire, at least one measurement device, a signal acquisition device and a signal processing device, wherein at least one stay wire is axially laid along the inner surface of the blade, and each stay wire One end is fixed on the inner surface of the blade near the blade tip, and the other end is connected to at least one of the measuring devices through an elastic element, and the pull wire drives the elastic element to undergo stretching movement with the deformation of the blade; at least one measuring device is fixed on the inner surface of the blade near the blade tip. The position of the hub is suitable for outputting a measurement signal according to the stretching movement of the elastic element driven by a cable connected to it; the signal acquisition device is respectively connected with at least one measurement device and a signal processing device, and is suitable for collecting and transmitting at least one output of at least one measurement device. A measurement signal is sent to a signal processing device; the signal processing device is adapted to calculate the deformation of the blade from at least one measurement signal.

Description

technical field [0001] The invention relates to the field of blade state monitoring, in particular to a system for monitoring blade deformation of wind power generation equipment. Background technique [0002] As an important renewable energy source, wind power has attracted widespread attention. The blades of wind power generation equipment are the key parts of the wind power generation unit to capture wind energy, and their health directly affects the operation of the entire wind power system. The structure and stress of the blades are quite complicated. Because the working environment of the blades is very harsh, spring, summer, autumn and winter, severe heat and cold, lightning, hail, rain, snow, sand and dust may cause damage to the blades of the fan at any time, so the blades become wind power generation equipment. the most accident-prone location. According to statistics, the accidents caused by blade damage account for about one-third of the total wind turbine acci...
