ABSTRACT: At present, the operational parallel compensating
capacitors can only through the protection action for the information, so we
can‘t location the fault capacitor. In order to obtain every parallel capacitor
running status information and meanwhile according to internal structure and
the operation mode of film capacitor, this paper established the physical model
on the single capacitor and the capacitors and simulated different forms of
capacitor fault model and calculated currents changes which flow through the
capacitor in every group. According to the above situation, we established fault
criterion matrix of capacitors. The simulation results show that the fault
criterion matrix can reflect capacitor running state information accurately, and
it positioned fault capacitor effectively.
