Abstract

Taking the series reactor in 10kV cascaded capacitor bank of a typical 110kV substation A as an object, and aimed at the burning fault happened when the reactor was in operation, this paper made a concrete analysis, combining theory with practice. Firstly the Power quality tracking test on 10kV bus installed the capacitor bank has been taken. Then based on the actual testing data and resonant amplification theory the reactor failure was analyzed theoretically. Finally, using simulation software PSCAD/EMTDC, the simulation model of substation A and power load was built and the simulation results verified that the 10 kV capacitor bank of substation A exists harmonic amplification effect. So the harmonic amplification effect is the main reason caused series reactor failure.
