Abstract
In this paper, based on the the field measured data, the correlation between the switching mode of the shunt capacitors, the harmonic amplification problems and the excessive noise of shunt capacitors is summarized. After that,this paper analyzed the operating environment of the shunt capacitors and series reactors theoretically, showing the mechanism of the harmonic amplification problems. On this basis, focusing on the resonance conditions, the requirements of harmonic amplification under different system short circuit capacities, shunt capacitor capacities and series resistance ratios are studied. At last, targeted prevention measures such as improving the series resistance ratio to prevent resonance occur are proposed in end of this paper.
