The Study of Ferromagnetic Resonance Overvoltage and its Suppression Methods in 35kv Power System

Abstract:

Ferromagnetic resonance overvoltage is an internal overvoltage and it often occurred in the power distribution system which neutral point ungrounded. A 35kV power system is used as the prototype to establish the 35 kV substation's simulation model which is based on the ATP - EMTP and ferromagnetic resonance overvoltage is researched and analyzed In this paper. The ferromagnetic resonance overvoltage which is stimulated by single-phase ground fault is studied in this paper studied and ferromagnetic resonance suppression methods were also studied. The results show that the nonlinear resistor is connected in the PT primary neutral side and small resistance is connected in the PT open delta are effectively methods which can restrain ferromagnetic resonance overvoltage.
