摘要
提出一种无辅助降压变压器的电气化铁道磁势平衡型混合补偿系统(railway ampere-balance based hybrid compensating system,RAB-HCS)。给出系统的谐波域数学模型,导出主变一、二次侧谐波分量的传递关系,揭示其谐波抑制机理。在此基础上对RAB-HCS的滤波及谐振特性给予定量分析,分析结果表明,本系统的滤波和谐振阻尼效果明显。最后基于实测数据的仿真结果以及实验验证了上述构想的正确性。
This paper proposed a transformerless railway ampere-balance based hybrid compensating system(RAB-HCS) for electrical railway. To reveal its harmonic suppressing mechanism, the mathematical model and transforming relationship in harmonic frequency were presented as well. Based on that, the harmonics filtering characteristics and the resonance damping performance of RAB-HCS were quantificationally analyzed, which shows its good performance. Finally, simulation and experimental results verified the above conceptions.
