摘　　要：在10 kV低压配电网中,由电磁式电压互感器铁芯饱和引起的铁磁谐振现象会严重影响电力系统的安全稳定运行。以某10 kV中性点不接地配网系统为研究对象,采用Matlab/Simulink建立铁磁谐振仿真模型,以单相短路接地故障消失作为谐振触发条件,研究系统对地电容对于谐振类型的影响。为优化Simulink仿真过程中修改元件参数时需逐一打开参数编辑界面等不足,创造性地引入Matlab图形用户界面(GUI),将参数调整、模型运行以及结果展示呈现在同一界面,在一定程度上提高了用户的使用体验。In 10 kV low-voltage distribution network,the ferroresonance phenomenon caused by the saturation of electromagnetic voltage transformer core will seriously affect the safe and stable operation of power system.In this paper,a 10 kV neutral ungrounded distribution network system is taken as the research object,and the simulation model of ferroresonance is established by using Matlab/Simulink.Taking the disappearance of single-phase short-circuit to ground fault as the resonance trigger condition,the influence of system to ground capacitance on resonance type is studied.In order to optimize the shortcomings of Simulink simulation,such as the need to open the model parameter editing interface one by one when modifying the control parameters,this paper creatively introduces the Matlab graphical user interface(GUI)to present the parameter adjustment,model operation and result display in a unified interface,which improves the user experience to a certain extent.
