【Abstract】 In this paper, the expressions of the rotor field currents in double-pole inducedexcitation synchronous generators are deduced when the field harmonics are taken into account, and the effects of harmonics on the rotor field current are discussed. By studying the eigenvalues of the state equations about rotor field current with rotor resistance not to be ignored, the effects of rotor resistance on the rotor field current are also investigated. The conclusions obtained are useful in further study and design of this kind of generator.更多还原
