A new steady-state model describes synchronous reactance over the whole operating region of the machine. The model takes into account main and cross-axis magnetic saturation. An analysis is presented of saturation as a function of the total air gap ampere-turns which shows that complicated relationships exist at leading power factors making such relationships unuseful. Two large turbogenerators of 13.8 kV, 150 MVA and 22 kV, 588 MVA are studied
