| 摘要: |
| 对１１０ｋＶ的Ｔ接线路及其所在的系统进行了比较详细的数字模拟，并对线路的内部与外部各处可能发生的故障进行了详尽的仿真计算，着重考察了故障对电压、电流序分量的工叔变化量的相位差值在不同位置故障时的数值及同一故障点不同过渡电阻接地故障时的数值，得出的某些结论，对继电保护的理论和实践都具有重要意义。 |

| Abstract: |
| A digital simulation on Teed line and its system is presented in detail.The simulation and computation results of faults on the line at different spots and with different species are reported.It is accounted for the influence of the transient ground resistance.The phase difference between the sequence components of the voltage and the relative current are computed.Some significant conclusions are achieved.It is of avail for both theory and practice of protection relaying. |
