Investigation of switching transients power cable lines
N.O. Emelyanov

Switching transients, accidents and other emergency situations can lead to overvoltage, that is dangerous for the equipment of electric networks. Such processes are characterized by a signal, the spectrum of which comes to 2 MHz. For modeling these processes, a cable model was created, that takes into account the variance.
The model is created in Matlab / Simulink as a four. The model is based on modified telegraph equation. Calculation of parameters, that depend on the frequency, was carried out with the help of numerical simulation in ANSYS. 
Verification of the cable model was realized by numerical simulation in ANSYS HFSS.
