Wind power blade damage monitoring and positioning system based on wireless acoustic emission sensor network

Abstract

The invention relates to the field of wind power blade health monitoring and safety evaluation, and particularly provides a wind power blade damage monitoring and positioning system based on a wireless acoustic emission sensor network. The wind power blade damage monitoring and positioning system based on the wireless acoustic emission sensor network comprises wireless acoustic emission sensor nodes (1), cluster nodes (2), a network management converging node (3) and a monitoring center, the wireless acoustic emission senor nodes (1) acquire blade crack data, the cluster nodes (2) carry out relay transmission of the data, and the network management converging node (3) converges the data. Advantages of a wireless sensor network and advantages of acoustic emission technology are combined, the damage monitoring and positioning system which is applied to wind power blades and is flexible in arrangement, high in extensibility, convenient to install and maintain and sensitive in crack sensing is built, and problems that acquisition points are installed and maintained difficultly, cost is high, extensibility is poor and the like in a traditional cable arranging process are solved. In addition, the wind power blade damage monitoring and positioning system is simple in integral arrangement, flexible in installation and convenient and quick to use.

Description

[0001] technical field [0002] The invention relates to the fields of wind power blade health monitoring and safety assessment, and specifically provides a wind power blade damage monitoring and positioning system based on a wireless acoustic emission sensor network. [0003] Background technique [0004] In recent years, with the country's strong support for the development of renewable energy, the rapid growth of wind power installed capacity and the continuous increase of stand-alone capacity have put forward extremely high requirements for the safety, reliability and operation stability of wind power equipment. A wind turbine is a power generation device composed of blades, transmission systems, generators, energy storage equipment, towers and electrical systems. Wind turbine blades (referred to as wind turbine blades) are the most important components, and their service status has a great impact on the safe operation of the entire wind turbine.
