Study On Fault-Tolerance Power Supply System Based On Dual-Winding Doubly Salient Electro-Magnetic Motor

The technology of multiple channels is used to increase the reliability of the aero power supply system. Because of its unique structure and outstanding characteristics, fault-tolerance power supply system based on dual-winding doubly salient electro-magetic motor is one ideal kind.Firstly, this thesis reviews the histroy of multiple winding motor, and then introduces the basic structure of dual-winding doubly salient electro-magetic motor and its maths model, static characteristic. Then the motor simulation model is built through finite element analysis software, and last this thesis introduces development history of the voltage adjuster and its work principles.Secondly, this thesis introduces the hardware and software design method of the fault-tolerance power supply system.Then to the part open circuit fault and full open circuit fault of two running mode for the two redundancy power supply, this thesis gives some simulation and experiment results.The excellent static, dynamic, fault-tolerance charactics of system is verfied by the simulation and experiment. And each running mode has its application situation.Last, this thesis introduces MATLAB engine technology which calls the two redundancy generator system's MATLAB simulation model in the VC++ environment. The fault-tolerance power supply simulation interface is implemented by the author, the interface is concise and it looks nice.
