A rational configuration of the single tuned filter is an effective way to suppress harmonics.According to the Thevenin equivalent model for the single tuned filter,this paper analyzes the harmonic suppression mechanism of the single tuned filter. In view of the harmonic problem of multi-harmonic sources in the distribution network, a step-by-step configuration method of single tuned filter for multi-harmonic sources in the distribution network based on Thevenin equivalent is proposed with the whole network harmonic control effect as the obj ective.In each step,the influencing factor expression of the configuration node for the single tuned filter is deduced.The effectiveness of the proposed configuration method of single tuned filter is verified through simulation analysis.
