A NEW APPROACH TO ANALYSIS OF SYNCHRONOUS MACHINES WITH ASYMMETRICAL ARMATURE WINDINGS(Ⅱ)——PARAMETER CALCULATION

<正> Parameter calculation is the key problem in analysing the AC machines with armatureasymmetries. The multi-loop method, which is effective on this subject, uses such parametersas the self-inductances of and the mutual-inductances between every stator branch, every dam-per loop and the field circuit. They are different from those used in Park's equations.The parameters of the stator branch are composed of those of related coils according to itscomposition. Two methods, the air-gap permeance analysis method and the field numericalanalysis method, are proposed to calculate the saturated parameters. And the methods arethen verified and compared with each other by application to a generator.
