Simulation Design of 5 MW Permanent Magnet Synchronous Generator Directly Driven by Wind Turbine with Combination of Inner and Outer Rotors
The permanent magnet synchronous generator of 5 MW output power,which is driven directly without gear system,was de-signed by equivalent magnetic-circuit method in this paper. The performance of the ultra-high-power directly-driven permanent magnet synchronous generator with designs featuring 378-slot and 78-pole as well as 324-slot was investigated. The drawbacks re-garding transportation inconvenience and large size were overcome based on the optimization of generator structure. Simulation results showed that the 5 MW permanent magnet synchronous generator with inner and outer rotors is feasible and effective.
