Abstract
The turbine-generator flux decay test is modelled using a transient analysis of the lumped-parameter equivalent-circuit model. The linked electric and magnetic circuits of the machine are represented by components calculated from design data. Magnetic capacitors or magnetic admittances are defined to represent the magnetic flux paths in the machine and the effects of eddy currents in the dampers and rotor iron are represented by magnetic resistors. The transient analysis of the flux decay for the magnetic circuit is performed in electrical terms, using the electronic circuit analysis program Spice 2, and used to calculate the machine terminal voltage during the quadratureaxis flux decay test. Computed and test results on a 500MW set compare well. The method is simple and gives insight into machine transient behaviour as well as enabling machine parameters to be calculated. The identity of each component of the machine is preserved in the model.
