Simulations of Hydraulic Pitch-regulated Mechanism of a Megawatt Wind Turbine

For modern VSVP (variable speed variable pitch,VSVP) wind turbine, more and more attention is focused on how to improve energy capture and reduce extreme or cyclic loads on crucial parts of the turbine.

Large-scale variable speed constant frequency wind generation system usually adopts adjustable pitch control technology in order to ensure output power above the rated power and safety of the system.

The numerical simulating the 3D internal and external mixed flow fields of adjustable pitch horizontal axis wind turbine on conditions of the dynamic parameters was worked out.
