摘　　要：The continuous power supply system,which eliminates the neutral section and realizes safe and reliable operation,shows a development trend in suburban railways.However,the access of a power quality compensator(PQC)may alter the impedance characteristics of the system and introduce additional harmonics with a broader frequency band,potentially increasing the risk of resonance.Accordingly,in this paper,an analytical method is first adopted in conjunction with a field test to construct a simplified harmonic model for an actual continuous suburban line.A modal scanning algorithm is then used to analyze the effects of the controller and filter in the PQC on the harmonic resonance of the suburban railway continuous power supply system.Based on the improved particle swarm optimization algorithm,a multi-objective optimization design for PQC is proposed that can suppress harmonic resonance,filter the harmonics,and reduce the cost while preserving the stability of the control system.Finally,a real case study based on the field test demonstrates the effectiveness of the proposed design.
