Abstract
The method in Ref. [1] is used to determine synchronous reactances for the turbogenerator at operating conditions in Part I [2]. The influence of saturation on the direct and quadrature reactances is studied and the difficulties caused by linear parameters in nonlinear theory are discussed. A modified phasor-diagram taking the small angles dγ and γq into account is developed. The results are given for a Westinghouse Electric Corp. 200 MVA, 15 kV, wye-connected, four-pole, 50 Hz generator. Available test data are compared with computations.Keywords
