摘要:
结合实际运行的地铁线路、车辆电气参数,重点研究了整流机组电气特性,提出基于整流机组外特性的地铁车辆短路电流的计算方法,建立“变电所 - 牵引网 - 地铁车辆”模型并进行了仿真分析,得出地铁车辆短路暂态过程计算结果与仿真对比,波形误差小于 5%。对实际运行工况进行应用分析,结果表明,模型计算可校验“车 - 网”保护配置的可靠性。研究工作为选择直流快速断路器、确定系统保护配置以及评估系统供电能力提供理论依据及数据支持。
Abstract:
Combined with the actual metro line and vehicle electric parameters, the electrical characteristics of rectifier unitwas analyzed in detail and the calculation method of short-circuit current occurring on the metro vehicle was proposed based on theexternal characteristics of rectifier unit. The substation-traction network-metro vehicle model was established and simulated. The shortcircuit transient process of metro vehicle was obtained. The comparison between the two results showed that the waveform error wasless than 5%. The application analysis of the actual operating conditions shows that the calculation can verify the reliability of thevehicle-network protection configuration. The research work provides theoretical basis and data support for selecting DC fast circuitbreaker, determining system protection configuration and evaluating power supply capability.
