FAULT DIAGNOSIS FOR TURBINE ROTOR BASED ON INFORMATION FUSION TECHNOLOGY
摘要
选取蚁群神经网络作为汽轮机转子故障诊断的初级模块
采用证据理论混合算法的故障诊断方法
对汽轮机转子的局部故障进行诊断
并将诊断结果作为证据体利用证据理论将各证据体进行合成
计算它们的基本可信任分配函数
从而判定故障及其类型。以汽轮机转子x、y方向的不平衡故障为例进行诊断
结果表明该方法可有效提高诊断的可信度
减少诊断的不确定性。
Abstract
Local fault diagnosis of turbine rotor was conducted by fault diagnosis method using evidence theory with hybrid algorithm
combined with ant colony algorithm-neural network model
and the results were considered as the evidence.Then the evidence theory was employed to fuse the evidences and calculate their basic trustable assignment function
so as to determine the fault and its type.Imbalance fault in x
y direction on the turbine rotor was diagnosed.Results show that
this method can efficiently enhance the reliability and decrease the uncertainty of the diagnosis.
