摘要
精确的接地故障电弧的数字仿真有助于设计和发展新的继电保护装置 ,但是由于电弧现象的复杂性 ,使得在以往的数字仿真中 ,仅仅用理想短路或者一个线性电阻来模拟接地故障电弧 ,大大降低了仿真结果的可信度。为解决这个问题 ,本文依据普通的电弧数学模型 ,给出了接地故障电弧的精确数字仿真模型 。
Exact digital simulation of fault arcs helps to design and develop new protection.The fault arc is so complex that it is simplified to be perfect short or linear resistance in digital simulation formerly.In order to enhance the reliability of digital simulation,the paper puts forward a exact digital simulation model of fault arcs based on general math model of fault arcs.The result of EMTP simulation proves the feasibility of the model.
