    摘 要:準(zhǔn)確評估輸變電設(shè)備運行狀態(tài)是電力企業(yè)生產(chǎn)技術(shù)工作的核心內(nèi)容。為提高電力變壓器故障診斷精度,對典型變壓器故障特征理論進(jìn)行研究,建立了區(qū)內(nèi)和區(qū)外的故障仿真模型,在此基礎(chǔ)上提出了基于多源數(shù)據(jù)融合的變壓器典型故障診斷模型。模型采用小波包分析法提取故障特征量,并進(jìn)行特征融合。實驗結(jié)果表明,所提的變壓器故障判別策略判斷結(jié)果更加精確且診斷時間較快。

    Abstract: Accurate evaluation of operation status of power transmission and transformation equipments is the core of production technology for electric power enterprises. In order to improve the accuracy of power transformer fault diagnosis, the paper makes research on typical transformer fault characteristics theories, builds fault simulation models in and out of the region, and then puts forward a typical faults diagnosis model of transformers based on multi-source data fusion. This model adopts the wavelet packet analysis method to extract fault characteristic quantity and makes them fused. According to the experimental results, this transformer fault diagnosis strategy is more accurate with less diagnosis time.
    Key words: transformer; fault diagnosis; data characteristics; data fusion
