This paper first presented a new wiring winding induction generator in order to realize the requirements for high voltage and large capacity of megawatt wind generator, which has two sets of winding in the stator. The high voltage from the main winding is output to the grid, and the assistant winding provide low voltage input for the rotor converter . This paper researched the structure, working principle and generator start-up mode of high voltage inner doubly-fed induction wind generator. Through the finite element method, electromagnetic properties of the generator was simulated and analyzed, and the prototype test was carried out. The simulation results and the experimental results show that, in the different wind speed, the assistant winding can provide low-voltage power supply stability for converter and the stator can obtain stable frequency voltage output, which fully realize the requirements for higher voltage and larger capacity.
