【摘要】 根据灰色系统理论,把电力变压器油中溶解气体含量视为灰色量,利用有限的故障数据,按照灰色预测的方法,对数值进行初值化和一次累加生成等处理,建立灰色预测模型群即GM(1,1)模型,对电力变压器运行时间内的状态进行精密诊断和故障预报。更多还原

【Abstract】 According to grey system theory,the content of dissolved gas in power transformer oil is regarded as grey value.Then using limited failure data and base on grey prediction method,the data are processed by initialization and the first accumulated generation operation,then grey prediction model groups,i,e. GM(1,1),are established to give the accurate diagnosis and failure prediction for the condition of power transformer in the operation time.更多还原
