摘要
总结了智能变电站背景下智能终端的八种典型故障缺陷查找思路,对其中断链故障查找归纳出“四看”的快速定位方法,并以某220 kV变电站主变高智能终端的缺陷查找过程,展示了思路及定位方法的运用;该方法从缺陷表象出发,多维度定位缺陷,层层递进,准确率高。总结其关键点,并对智能变电站智能终端缺陷查找中遇到的问题,从模型告警信息细化、智能录波器功能完善、缺陷定级细化三个角度提出了展望。
The defect location ideas for eight typical faults of intelligent terminals in intelligent substations are summarized.For the positioning of broken chain faults,a fast location method with“four looks”is proposed.The ideas and application of this method are demonstrated with a practical defect location process of the intelligent terminal of the main transformer in a 220 kV substation.This method starts from the defect appearance and locates the defect in multiple dimensions with step-by-step progresses,thus of high accuracy.Also,the key points of this method are summarized.Considering the problems encountered in defect location of intelligent terminals in intelligent substations,prospects are made from three perspectives:refinement of model alarm information,improvement of intelligent fault recorder functions,and refinement of defect classification.
