Health monitoring system and method for wind generator system structure

Abstract

The invention discloses a health monitoring system and method for a wind generator system structure. The system provided by the invention comprises a data storage analytical device and a data collecting device, wherein the data storage analytical device and the data collecting device are communicated through a wireless signal, the data storage analytical device comprises a mechanical model analytical module, a data receiving module, a structure safety judging module, a vascular grade judging module and a vascular execution module; the data collecting device comprises a sensor group and a data transmitting module, and the sensor group is connected with the data transmission module through a wire cable; and the system judges whether the structure is damaged or not through a certain detection means and a method, the locating and evaluation of the damage are carried out to avoid the damage, thereby realizing the damage detection of a wind power generation infrastructure and health monitoring of a discriminating structure. Meanwhile, the invention also aims to provide a health monitoring method for the wind generator system structure.

Description

technical field [0001] The invention relates to a structure health monitoring device, more particularly to a wind turbine structure health monitoring device, which belongs to the field of electrical automation testing. Background technique [0002] At present, civil engineering accidents occur frequently in our country, such as sudden collapse of bridges, sudden collapse of houses, collapse of large-scale wind power generation structures, etc., causing heavy casualties and property losses, which have aroused people's concern and attention to the safety of major projects. In recent years, as a large number of megawatt-level new wind turbines in my country have been put into large-scale production and operation in a hurry, quality and operational reliability problems have become prominent, and many operational failures have also occurred, increasing technical and economic risks. Due to the limitation of the distribution of wind resources, wind farms are mostly distributed in d...

AI Technical Summary

Problems solved by technology

Due to the limitation of the distribution of wind resources, wind farms are mostly distributed in deserts, mountains, and pastures far away from cities; with the development and utilization of offshore wind energy, offshore or coastal wind farms will become an important development direction of wind power in the future. The operation management and maintenance of the unit have brought great difficulties
