Abstract

In view of such problem that the present capacitor online monitoring device is susceptible to the fault of instrument transformer and the secondary circuit

a kind of integrated online monitoring method of shunt capacitor capacitance based on redundant data is proposed in this paper. The method introduces information fusion technology into the online monitoring of capacitor

makes fully use of the redundant information of multiple data sources to obtain real time capacitance on the basis of weighted data fusion algorithm and relevant criteria. The measurement accuracy of capacitance is free from the fault of any instrument transformer coil or the secondary circuit. For multiple faults occurring in different data windows

the bad data can be eliminated by relevant criteria to obtain correct results. The method can be integrated into existing capacitor protection and monitoring devices to reduce investment in new equipment and simplifywiring.
