A novel green electric drive system

As a potential green electric drive device, the two important green indexes for the systematical design of the switched reluctance machine system with the aim of green, such as the cost of the per unit effective volume output of the system and the systematical efficiency of the machine, are considered. The green-oriented control strategies for the machine system operated in the motor drive, electric traction and generator system, which contribute to increase the systematical efficiency and reduce the cost of the system, are presented. The bases of implementing fault tolerant control strategies are also introduced. Based on the important green indexes and control strategies described two developed prototypes, the electric locomotive switched reluctance motor drive system and variable speed axial-flow fan switched reluctance motor drive system, are given.
