Negative sequence eddy current field analysis of a 1055 MVA turbogenerator by using 3D finite element methods

The 3D negative sequence currents arising from unbalance system operations in large turbogenerators are studied by using the finite element method. The mathematical models of the three dimensional negative sequence eddy current fields of large turbogenerators considering the flexible slots are first...
