基于电流信号分析的风力发电机齿轮箱故障诊断
Diagnosis on Fault of Wind Power Generator Gearbox Based on Current Signal Analysis
摘要
Abstract
It is able to find out fault characteristics by analyzing current signals at the terminal of generator when the gearbox of wind power generator fails .Therefore ,experiment bench for wind power generator units is firstly established and then developing faults of one to eight sides pitting corrosion and one to four sides cracks are processed to the sun gear .Fault ex‐periment is carried out by using the processed faulted gear and current signals at the terminal of generator are collected for bispectrum analysis .On the basis of analysis ,it is discovered that there are faulted frequencies in current when the gear failed and current amplitude will decrease with fault degree deepening .By means of comparison and verification with theo‐retical analysis on faulted current ,it is known that analysis on current signals at the terminal of generator can effectively ex‐tract fault characteristics of the gearbox .关键词
