| Abstract |
This paper investigates advantages of new
combination of the induction generator for wind power and
the power electronic equipments. Induction generator is
popularly used for the wind power generation. The
disadvantage of it is impossible to generate power at the
lower rotor speed than the synchronous speed. To
compensate this disadvantage, expensive synchronous
generator with the permanent magnets sometimes used. If
HVDC transmission is used to connect the offshore wind
farm to the mainland, using AC/DC converter system is no
more disadvantageous. However, to omit the expensive
permanent magnet is desirable. In proposed scheme, the
diode rectifier is used to convert the real power from the
induction generator to the intermediate dc voltage, while the
reactive power necessary to excite the induction generator
only is supplied from the voltage source converter (VSC).
This means that the rating of the expensive VSC is
minimized and total cost of the wind power generation
system is decreased compared to the system with
synchronous generator. |
