Research on suppression measures of ferromagnetic resonance based on ATP-EMTP [PDF]
Journal of Physics: Conference Series, 2020 Abstract Aiming at the electromagnetic transformer of a 35kV substation in a certain area, a simulation model of ferromagnetic resonance based on ATP-EMTP software was established. Several methods of suppressing ferromagnetic resonance overvoltage were analyzed, and it was found that the harmonic elimination device could not completely ...
