Using finite element method analyzing eddy current field of busbars in indoor substation

This paper researched two-dimensional and three-dimensional eddy current field questions satisfied large current busbars based on finite element method aiming at heavy current plane busbars with being generally used in indoor substation. Change of magnetic inductive intensity is discussed. Compared with actual measured data, maximum error is less; The paper emphases on studied changes of force and magnetic energy and power loss along with change of different working current so that electromagnetism parameters of busbars in indoor substation are forecasted during the period of max-current-peak avoiding accident happened.
