Abstract

In order to solve the problem of harmonic resonance in shunt capacitor at 220kV or 110kV transformer substation, use the PSCAD software to construct harmonic impedance models of capacitor, transformer, load, short impedance and harmonic source, give resonance objective function such as harmonic voltage amplification factor on load bus, etc. With minimax optimization, the maximum values of objective function in all the power grid parameter space are minimized by changing reactance rate. The conclusion is: resonance is eliminated with best effect and generality by the rate 12%; resonance is eliminated with second effect by rate 4.3% ~ 4.5%, but the rate 4.3% ~ 4.5% has better technical and economic value and Suitable for most of 220kV and 110kV substation.
