摘要

为了确定特高压直流输电工程中直流滤波器各设备的暂态定值

需要对直流滤波器的故障工况进行研究。根据工程经验

在暂态定值研究中需要考虑的故障工况包括直流滤波器高压端（或直流极线）对地短路和直流极线上侵入操作波。通过在仿真程序中建立直流滤波器的故障模型

并充分考虑不同的对地故障距离对直流滤波器各设备的影响

从中选出各设备最苛刻的应力。文中通过对三调谐滤波器的故障仿真对该方法做了进一步说明。仿真结果显示

该研究方法对确定直流滤波器暂态定值具有决定性作用。

Abstract

In calculating the transient stresses of DC filters components of UHVDC project

it is necessary to take a study on fault cases.According to project experience

HV terminal to ground fault and switching surge should be taken into account.By establishing fault case circuit models in simulation program

and considering the effect of different ground fault distance

the decisive stresses of the components can be selected from those results.This method is illustrated in detail by simulating on a triple tuned filter.The simulation result shows that this method is decisive for DC filter transient ratings.
