| Abstract: | The main wear particles of wind turbine gearbox are iron particles.The increasing of iron particle content can directly reflect the wear state of wind turbine gearbox.In this paper,the Fe content of the gear oil in use for wind turbine gearbox is monitored by means of Spectro oil spectrum analyzer.By measuring the increase of Fe content and available hours of wind turbine in a period of time,the increase of Fe content per unit of available hours(ΔQFe)is calculated.Reliability theory is introduced to study the distribution law ofΔQFe,taking the monitoring data of in use gear oil of wind turbine gearbox as an example,the threshold model of gearbox wear state based onΔQFe is established.This wear threshold model established on the basis of large sample data can more accurately analyze the wear state trend of the wind turbine gearbox,and provide a reference for the evaluation of the wear state of the wind turbine gearbox. |
