Study on Load Characteristics of a Mini Permanent Magnet Synchronous Generator for Wind Power
A mini permanent magnet synchronous generator (PMSG) for wind power with 24/8 poles was designed, and the mathematic model combining field equation and circuit equations was established. Based on the model, the transient process was analyzed by finite element simulation, and phase voltage, electromagnetic torque both on condition of no-load and load were investigated. Then the characteristics of load voltage, output power, and transfer efficiency under different loads were obtained, which could provide load matching reference for maximum power controllability of the various speed wind turbine. The investigation of the proposed PMSG shows that the rated load voltage is about to be 56 V, the rated power 450 W.
