In order to suppress the danger of harmonics

one effective measure is to put reactor in series in the capacitor circuit.Analysis and simulation results show that different harmonic currents flowing into the capacitor circuit is different due to different reactance ratio of series reactor.Based on this conclusion

this paper proposes the principle and method of selecting the reactance ratio and it is thought that selection of reactance ratio depends on such factors as the main harmonic frequency

capacitor capacity

short-circuit capacity of bus and permissible operation conditions of the device.
