Abstract

A novel dual power flow wind power generation system based on electrical variable transmission (EVT) is proposed which combines the advantages of direct-driven and non-direct-driven systems. In this paper, the principles of the dual power flow wind power generation system are presented. The dynamic model and operation modes of the double layer permanent magnet outer rotor based EVT are introduced. Furthermore, the operation processes and control strategies of the novel system are simulated and analyzed. An EVT prototype machine is designed and verified by finite element analysis (FEA).
