摘要
本文建立了牵引变电所多串多次滤波器投切的暂态过程仿真的电路模型和数学模型,并给出各滤波支路的涌流和操作过电压的时域解。本文给出的数学模型能适用于电气化铁道空载和负载各种情况下的滤波器投切,并适用于计算单个滤波器支路、滤波器组整体或其他组合方式下的投切暂态过程。最后给出一些有助于工程设计的重要结论。
In this paper,the circuital and the mathematical models forthe transient process of multi--arm single--tuning filter switching in trac-tion substations are set up, and the time--dependent solutions for therush--current and operation over-voltage of each branch have been given.The mathematical model is suitable for all loaded and non--loaded condi-tions of electric railways and can be used to simulate the switchingprocess of combined states of filtering branches. Some useful conclusionsare reached in the end for engineering design.
