Simulation of switching Overvoltages and Field validations

EMTP USA User Conference 2019 - Ilhan Koçar


This presentation is on the simulation of switching overvoltages on transmission lines with trapped charge, validation of EMTP line models, modeling of prestrike in statistical simulation studies and discussion of necessary simulation practices by means of validations with field tests.


Objectives: - Identify simulation practices to produce the field measurements en EMT simulation - Validation of line models - frequency dependence - Discussion on modeling approaches, simulation practices, sensitivity to electrical parameters - Evaluate maximum overvoltages - How to perform statistical simulations, model prestrike and include corona in statistical simulations efficiently.
