文摘Based on analysis and calculation of the relation between current harmonics and MMF harmonics in the dual-stator winding multi-phase high-speed induction gen-erator with a rectifier load,a new idea,which divides the generator system into two sub-systems to be analyzed individually,is presented.For the sub-system of the 12-phase power winding with a rectifier load,the loop current method is used to establish network equation set in terms of the network graph theory.The numerical stability problem is solved by alternating use of fixed time-step and varied time-step,and the voltage and current with their fundamental components of the power winding are obtained.For the other sub-system of the induction generator with dual-stator winding and solid cage rotor,the electromagnetic field analysis method and the multi-variable optimization approach are combined to get the con-trol winding current and stator frequency.Calculated results well match experiment results,indicating that the new proposed method is of effectiveness and high ac-curacy.
