摘要:
为阐明动车组过分相阻抗保护误动作时二次谐波闭锁失败的原因,文章推导了车载变压器空载合闸时高铁接触网馈线电流中二次谐波分量的解析表达式,指出合闸初相角、变压器剩磁及负载是影响二次谐波闭锁系数的重要因素;通过对动车组过分相暂态过程仿真,找出了容易造成闭锁失败发生的区间以及易发生该现象的牵引变电所类型。结合事件发生时车载变压器发生励磁涌流,测量阻抗进入保护区间导致阻抗保护误动作的特点,仿真结果与实测数据相吻合,验证了分析的正确性。
Abstract:
In order to clarify the failure reasons of the second harmonic locking of impedance protection when EMU passing through the electrical phase-splitter, this paper derived the analytical expression of the second harmonic components in the feeder current of highspeed railway catenary network and pointed out that initial phase angle, residual flux and load are the important factors affecting the second harmonic locking coefficient. The occurrence interval of locking failure and the type of traction substation being easy to lock are found, which were simulated by the transient process of the EMU through the electrical phase-splitter. Simulation results are in good agreement with the measured data in combination with the characteristics of the fault protection events of the high-speed railway impedance protection, which verifies the correctness of the analysis.
