    摘 要:為了檢測(cè)氣體絕緣組合電器(GIS)故障,提出了一種基于單分類支持向量機(jī)(OCSVM)的設(shè)備故障檢測(cè)方法。該方法以選取GIS金屬外殼振動(dòng)加速度以及氣體壓力作為狀態(tài)監(jiān)測(cè)量,為了解決設(shè)備振動(dòng)幅值受負(fù)載變化影響的問題,提取外殼振動(dòng)信號(hào)峭度因子,與氣體壓力共同作為狀態(tài)特征量;利用GIS正常狀態(tài)特征量數(shù)據(jù)訓(xùn)練OCSVM模型,得到設(shè)備故障檢測(cè)器,并利用故障檢測(cè)器檢測(cè)當(dāng)前狀態(tài)特征變量的異常程度來實(shí)現(xiàn)設(shè)備故障的檢測(cè),現(xiàn)場(chǎng)實(shí)測(cè)數(shù)據(jù)分析結(jié)果驗(yàn)證了該方法的有效性。

    Abstract: In order to detect the fault of Gas insulated switchgear, a fault detection method based on one class support vector machine (OCSVM) is proposed.In this method, the vibration acceleration and gas pressure of the GIS metal casing are selected as the state monitoring variables.In order to solve the problem that the vibration amplitude of GIS metal enclosure is affected by the load, the kurtosis of the metal enclosure vibration signal is extracted and the gas pressure is used as the state characteristic quantity.The OCSVM model is trained by using the GIS normal state feature data to obtain the equipment fault detector, and the fault detector is used to detect the abnormal degree of the current state characteristic variables to realize the detection of equipment faults.The results of field measurement data analysis verify the effectiveness of the method.
    Key words: gas insulated switchgear; one class support vector mechine; kurtosis; air pressure; fault detection
