摘要
在中性点绝缘的复杂电网中 ,因系统突发单相接地故障而激发的铁磁谐振现象经常出现 ,利用MATLAB内建的仿真工具实现了由于电压互感器非线性励磁电感和系统对地电容匹配而引起的铁磁谐振暂态过程的数字仿真 。
In the neutral point non earthed complicated power system, ferroresonance overvoltage caused by single phase earthed fault happens frequently. This paper employs MATLAB based simulation to achieve digital calculation and simulation of the ferroresonance transient process due to matching of non liner exciting inductance of PT and network to earth capacitance. Different ways about ferroresonance suppression and their effects are discussed and simulated as well.
