摘要
以灰色系统理论为基础 ,研究电气绝缘故障诊断的灰色预测模型新模式及其应用 .建立了适用于电气设备绝缘故障诊断的一次拟合参数灰色预测的新模型 ,并给出了新模式的建模过程 ,提出将原始数据经弱化算子作用后进行一次指数平滑运算并对背景值进行改造的方法 ,并以实例进行了检验 ,结果表明该方法的可行性和有效性 .
Based upon the gray system theory, the new mode of gray forecasting model for electrical insulation fault diagnosis and its application were studied. Firstly the new mode of gray forecasting with first-order fitting parameter suited for electrical insulation fault diagnosis was established. And then the modeling process for the new mode was presented. Finally the method was presented which was processing original data by means of the effect of weakening operator and the first-order exponent flatness operation, and then re-constructing background value, and according to the field example examination, the result shows that such method is feasibility and validity.
