Investigation of possible ferroresonance for a voltage range: realisation of a system event with a laboratory set-up.

SUMMARY The paper presents an analytical and numerical investigation carried out on part of an electrical power network exhibiting ferroresonant behaviour as well as experimental investigation on its physical model. The investigations were carried out in order to estimate the extent of predicting the range of voltage source amplitude values at which the initiation of ferroresonance depends on values of initial conditions and phase shift. For this range of voltage source amplitude values (termed as possible ferroresonant range in the paper), the impact of initial conditions and phase shift of voltage source on the initiation of ferroresonance is determined using a numerical investigation and an experimental set-up. Reasons and consequences of disagreement of parameter values of the original and physical model are determined. Copyright © 2011 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]
