Analysis of the Ferroresonance of 110 kV Power Systems

Abstract:

Ferroresonance is a usual internal overvoltage in power system; it mostly occurs in distribution network that neutral hasn’t grounded directly, but it also happens in the high voltage grid that neutral-grounded system frequently. This paper introduced the fundamental theory of ferroresonance. An 110kV substation has been used as the model, to emulate the waveform of its ferroresonance, and also discussed the measure to remove the ferroresonance.
