摘　　要：变电站及其变压器在线状态监测系统的出现,为电力设备的运维管理提供了一种先进、高效的解决方案。文章提出了变电站及变压器在线状态监测系统(Onling Condition Monitoring System, OCMS),该系统有助于用预测性维护取代变压器的预防性维护。OCMS是一种成本效益高、在线且准确的工具。通过实验结果分析,对所提出的系统效果进行了评价。OCMS适用于正常或异常故障的变压器,如通过溶解气体分析检测到的异常故障。因此,OCMS与市场上用于变压器状态监测的其他健康指数算法不同,性能更优异。The emergence of online status monitoring systems for substations and their transformers provides an advanced and efficient solution for the operation and maintenance management of power equipment.This article proposes an online condition monitoring system(OCMS)for substations and transformers,which helps to replace preventive maintenance of transformers with predictive maintenance.The designed OCMS is a cost-effective,online,and accurate tool.The proposed system results were evaluated through experimental analysis.The designed OCMS is suitable for transformers with normal or abnormal faults,such as abnormal faults detected through dissolved gas analysis.Therefore,it is very different from other health index algorithms used for transformer condition monitoring in the market and has better performance.
