Wind turbine air gap real-time detection system and method

Abstract

The invention relates to a system and a method for detecting the air gap of a wind power generator in real time. The system comprises a wind power generator, a laser sensor and a capacitive sensor, wherein the distance between the stator silicon steel sheet of the wind power generator and the rotor magnetic steel is an air gap of the wind power generator, at least one laser sensor is fixedly connected to the rotor shell through a mounting support; at least one capacitive sensor is pasted on the surface of the stator silicon steel sheet, and a laser beam emitted by the laser sensor is irradiated on the surface of the capacitive sensor, a set of sensor measuring devices are formed for measuring the air gaps of the wind power generator. According to the system and the method, the load of a fan can be evaluated in real time, the load can be controlled in advance through the fan, and the stator and the rotor can be prevented from being scratched.

Description

technical field The invention relates to a wind power generator air gap detection system, in particular to a real-time detection system and method. Background technique The wind turbines currently on the market do not have a perfect solution for the real-time assessment of the real-time risk of the air gap and the load on the structure. Some solutions even measure the air gap, but do not take into account the simultaneous measurement of multiple positions in the axial direction, such as the drive end, non-drive end and mid-end. The resulting measurement is also not the minimum value of the air gap. Contents of the invention In order to realize the real-time monitoring of the absolute air gap between the stator and the rotor, the present invention provides a real-time detection system and method for the air gap of a wind power generator. Thereby preventing the occurrence of stator and rotor rubbing. To achieve the above object, the technical solution of the present inv...
