Abstract

Abstract: 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.

Key words: ferroresonance, electromagnetic voltage transformer, Matlab-Simulink, graphical user interface (GUI)
