Analysis on Double Resonances of Generator Stator and Rotor Coupling Rigid Model


When the generator starts up in frequency conversion, there is high harmonic in electricity. The generator stator and rotor coupling rigid model has been established. In this condition, high harmonic magnetometive force has been expressed and the component parts of electro-magnetic have been obtained. Double resonance has been analysis using energy numerical method. The first approximation solution and the transient process curve have been acquired, as well as the effect of electromagnetic damping and electromagnetic force to resonance. There will be practical value to the investigation on low frequency resonance of generator,.
