| 摘 要： | 某型高速动车组型式试验过程中,由于脉冲整流器载波移相逻辑错误导致网侧谐波含量被放大,网压瞬时值增加,影响了同一供电臂下其他动车组的正常工作。通过对测试数据进行谐波分析,结合动车组网侧谐波特性,找出了网侧谐波含量被放大的原因。通过厂家更改脉冲整流器控制软件,成功解决了该型动车组运行时网侧谐波含量过大的问题。

| Abstract: | In the type test process of a certain type AC-Driven Electrical Multiple Unit(EMU),because of the logical error of pulse rectifier’s carrier phase shifting control,line side harmonic content is amplified.Transient value of line voltage increases and the normal work of other EMU under the same power supply arm is impacted.Through harmonic analysis on test data and line side harmonic characteristic of EMU,this article finds out the reason why line harmonic content is amplified.By modifying pulse rectifier’s control software,successfully solve the problem of too much line side harmonic content in the operation of the EMU. |
