电力电缆运行故障仿真分析研究

Simulation Analysis of Power Cable Operation Fault

通过研究电力电缆运行中常见的故障,将运行故障波形与正常波形进行对比,快速找到电力电缆运行中的故障类型,从而有利于快速寻找电力电缆故障位置和检修。采用对比的方法,结合MATLAB/Simulink对故障类型进行仿真分析可得,短路故障将产生较大的电流,对供配电系统和电力电缆都有较严重的影响,尤其三相短路故障,对系统影响最严重。因此,研究电力电缆运行故障类型尤为重要。

By studying the common faults in the operation of power cables,comparing the fault waveforms with the normal waveforms,we can quickly find the fault types in the power cable operation,which is helpful to quickly find the fault location and maintenance of the power cable.Using a comparative method,combined with MATLAB/Simulink to simulate and analyze the type of failure,it can be obtained that short-circuit failure will generate a large current,which has a serious impact on the power supply and distribution system and power cables,especially three-phase short-circuit failure The impact is most severe.Therefore,it is particularly important to study the types of power cable operation failures.
