The invention discloses a high-frequency resonance suppression method and system for a railway traction power supply system. The method comprises the following steps: collecting power supply system data; constructing a parallel combination of a single-tuned filter and a C-type filter, and establishing a vehicle-network coupled traction power supply system simulation model; under multiple working conditions, adjusting single-tuned and C-type filter combination parameters, and performing multi-working-condition harmonic characteristic and negative sequence analysis on the traction power supply system; under the same working condition, harmonic characteristic and negative sequence analysis is carried out on different train quantity conditions by utilizing a single tuning and C-type filter combination, and harmonic suppression is carried out by utilizing the filter combination. According to the high-frequency resonance suppression method for the railway traction power supply system, under the condition that the number of running trains is considered, traction power supply coefficient harmonics can be effectively treated through the high-frequency resonance suppression method for the railway traction power supply system with the combination of the single tuning filter and the C-type filter, and the total harmonic voltage distortion rate is reduced.
