| Summary: | Ferroresonance is a nonlinear phenomenon that damages the undesired, destructive system for energy transmission lines.
The formation and development of this overvoltage ferroresonance phenomenon is an important research topic as a mysterious
event in energy power systems. In this study, Seyit Omer-Iklar energy transmission line from Turkey’s electrical transmission
networks was modelled using real parameters. Ferroresonance scenario was created on the model. The energy transmission
system with the scenario is set to a simulation time of 4 seconds. The first two seconds are set to normal. By cutting off the
transmission line in the 2nd sec., the system is provided with ferroresonance drift. According to the data obtained therefrom,
spectrograms, instantaneous amplitude, instantaneous frequency and instantaneous phase were conducted. The analyses have
made clear that the instantaneous frequency amplitude defined the system’s ferroresonance moment very well. |
