Online monitoring system for tilt and wobble of wind power tower barrel

Abstract

The invention relates to an online monitoring system for tilt and wobble of a wind power tower barrel. The system comprises a processor, a display, a collector, a tilt angle sensor located at a towerbase, at least one tilt angle sensor located at the tower barrel, a tilt angle sensor located at a tower cabin and at least one acceleration sensor located at the tower cabin; the tilt angle sensors and the acceleration sensors are connected with the collector through cables; the collector is used for collecting angle data of all the tilt angle sensors and acceleration data of all the accelerationsensors, and sending the data to the processor; and the processor is used for calculating out a real-time eigenvalue according to the angle data and the acceleration data, storing the real-time eigenvalue in a memory, giving an alarm and when the real-time eigenvalue is larger than or equal to a corresponding threshold value, and realizing an early warning function by a weighted average model.

Description

technical field [0001] The invention relates to the field of on-line monitoring of wind power towers, in particular to an on-line monitoring system for the inclination and shaking of wind power towers. Background technique [0002] The wind tower is one of the important stress-bearing parts of the wind power generation device. The normal working state of the wind power tower is the basic guarantee for the normal power generation of the wind turbine. If the tilt and vibration of the wind power tower exceeds a certain level, it will often cause serious accidents such as the collapse and breakage of the tower, endangering the safety of personnel and causing major financial losses. [0003] At present, some methods and systems for tower condition monitoring do not meet the needs of tower monitoring, and these systems and methods often have disadvantages such as time-consuming and laborious, and low monitoring accuracy. Therefore, a new type of system and method is needed to mo...
