摘要:
为了从理论上分析列车分别以牵引工况和再生工况通过地面过电分相时产生的过电压过电流情况,首先利用变压器的T 形等效电路建立列车带载通过电分相的完整等效电路,然后推导出列车在2 种不同工况下通过电分相时,由于分合闸产生的电压冲击和电流冲击的具体表达式,并基于此表达式给出了避免过电压、过电流的方案。理论分析表明,列车牵引工况通过电分相时,带载分闸时会产生截流过电压冲击,合闸则不存在电流冲击;再生工况通过电分相时,如果开关切换时间过短,带载分闸会产生截流过电压冲击,合闸时也存在电流冲击,而且还存在很大的稳态电流,必须封锁脉冲整流器。仿真结果验证了理论分析的正确性。
Abstract:
To theoretically analyze the overvoltage and overcurrent when the train runs through neutral section under traction condition and regeneration condition, the equivalent electrical circuit was developed based on T equivalent circuit of transformer. Then, expressions for the voltage and current under two different conditions at switching time were presented. Based on those expressions, solutions were suggested to avoid overvoltage and overcurrent. Theoretical analysis showed that under traction condition there was intercepting overvoltage at the instant of the switch being turned off and no surge current at the instant of switch being turned on; under regeneration condition intercepting overvoltage occured at the instant of switch being turned on and surge current existed at the instant of switch being turned on. Moreover, there was a big steady current in the latter case, so the rectifier must be blocked. Finally, the validity of the theoretical analysis was verified by simulation results.
