The type 2 wind turbine, also called a variable-speed turbine, attempts to solve some of these problems. A device called a converter is integrated into the turbine to precisely control the ...

In low wind speeds, wind turbines are operated at variable speed and fixed pitch in order to capture as much energy as possible. In high wind speeds, the pitch angle is adjusted to limit the captured ...

The adjustment speed of up to 300° of crank angle (CA ... of an exhaust gas turbocharger with electrically actuated variable turbine geometry (VTG). Due to early intake valve closing in the ...

This chapter and the next are concerned with the setup and design of variable-speed wind turbine controllers. This one focuses on fixed-pitch WECS, whereas the following one deals with variable-pitch ...
