| Research Abstract |
The induction generator is the most popular and the lowest cost machine for wind power generation. However it cannot generate power at lower speed than the synchronous speed. So、 sometimes、 the permanent magnet synchronous generator with frequency conversion system is installed. However、 the cost of the machine is much higher than the induction machine. And the strong magnets require rare earth material whose cost may be going high in near future. Hence I have proposed to use the induction generator with voltage source converter (VSC) . The research results verify the VSC rating is down to 17% of rated power output.
