This article investigates the chaotic behavior of a transformer during ferroresonance under single and double open conductor configurations. The nonlinear characteristic of transformer saturation is modeledas describedin[1]whichalso describes chaotic behavior of a power transformer under single open conductor configuration. The solutions of the nonlinear differential equations which describe a ferroresonant circuit can be categorized into three types, i.e., periodic, quasiperiodic, and chaotic. Simulation of each of these types has been carried out using the fourth order Runge-Kutta method and results are corroborated using EMTP [2]. The results reveal that the type of response from both configurations is influenced by the transformer saturation characteristic, core loss, and the amplitude of the voltage source. However, the double open conductor configuration exhibits greater sensitivity to parameters and chaotic behavior for lower values of voltage source. Also, the steady state bifurcation diagram generated using a continuation procedure reveals the occurrence of contiguous stable and unstable fundamental frequency solutions, a behavior that is unique to this configuration. |
