We updated and improved the 20kw 30kw variable pitch controlled wind turbine controller design.  Remove the dump load, add the silicon controlled rectifier control; The relay was changed to relay module.  Siemens control components.

50kw variable pitch controlled wind turbine design changed. The generator moved to the back of wind turbine main body. The whole wind turbine balance is more better than previously design.  Add the outside cover on wind turbine main body. Look more beautiful.
