基于UIOs的风力机传动系统多故障诊断
Multi-Fault Diagnosis of Wind Turbine Drive System Based on UIOs
摘要
Abstract
The fault diagnosis of wind turbine identifies faults and acquires fault information by extracting and estimating the operating data.At present,the fault detection of wind turbine mostly takes into account the single fault,but faults may occur simultaneously in actual projects.By designing unknown input observers,multiple fault diagnosis and isolation of actuators and sensors of the wind turbine drive system are realized.A bank of unknown input observers were designed for different types of faults.Each unknown input observer in the observers generates a residual signal that is not sensitive to the corresponding fault but sensitive to other faults.Single or multiple fault diagnosis can be accomplished by comparing the residual signals of the observers.The fault model of wind turbine drive system was established.The simulation results show that the method is feasible.关键词
