Abstract: In order to improve the intelligent operation and maintenance capabilities of ultra-high voltage substations and enhance the safety of gas insulated metal enclosed switchgear(GIS) operation, a GIS state warning system based on multi information fusion was designed and developed. Firstly, by analyzing the fault characteristics of GIS and the characteristic changes of insulation gas SF6 during the equipment fault process, the monitoring mechanisms of different types of faults in GIS were obtained; Then, the D-S multi information fusion fault warning decision algorithm was introduced to achieve online detection, intelligent decision-making, and automatic grading alarm of GIS faults.The application experiment of the system was carried out at ultra-high voltage Nanyang station, and the experimental results proved the accuracy of the monitoring of the early warning system, realized the online intelligent monitoring function of GIS, and improved the intelligent operation and maintenance capability of the substation.
Key words: gas insulated metal enclosed switchgear; multi information fusion; insulation gas; state warning system; ultra-high voltage;substation; partial discharge
