摘 要: 介绍了C型行波法的测距原理,利用ATP仿真软件对10 kV多分支配电线路单相接地故障进行仿真,通过MATLAB对仿真数据和图形进行分析,比较正常线路和故障线路波形,找到了第一个波形畸变点并以此来确定故障距离。结果表明测距精度满足实际要求,从而验证了C型行波法在配电网故障测距中的可行性。 The principle of type C traveling wave fault-location method was introduced. Many simulations were taken by ATP software for single-phase earth fault in a 10 kV power distribution line with many branches. Simulation data and figures were analyzed by MATLAB, comparing the normal line waveform and the fault one, the fault distance was determined by the first distortion point. As a result, the simulations indicated that the fault-location precision meet the actual requirement, type C traveling wave fault-location method was feasible for the fault location in distribution network.
