HP/VAWG

HORIZONTAL PLANE / VERTICAL AXIS WIND GENERATOR

The horizontal plane or vertical axis wind generator is actually a very old design.  It has distinct advantages over the conventional propeller type wind turbines (HAWT) in that it can develop greater torque at lower speeds, is silent when operating, poses no more danger to winged creatures than a multi-story building and can be easily adapted to low wind speed areas.  Unfortunately, the early designs of the VAWT were hampered in their functionality by available light weight materials and effective methods to overcome the friction and other forces which contributed to the turning resistance of the turbine.   Additionally, in the late 1940’s much R&D was spent on development of propeller driven aircraft in an effort to fly faster than sound.  The innovations from that aircraft research apparently spilled over into the HAWT R&D programs of the later portion of the 20th Century causing the propeller driven HAWT to develop much faster than its Vertical counterpart.  However, with the onslaught of mega wind farms an obscure, but serious problem is emerging for the HAWT industry.  Land area suitable for wind farms is shrinking and the output capacity of the HAWT struggles to exceed 5MW.  Output capability per unit area and overall efficiency are becoming the market drivers in the wind power arena.  Outputs must be increased along with efficiencies to solve this emerging power density problem.

The Baram Engineering Limited (BEL) , Korea,  HP/VAWG technology borrows from several prominent engineering disciplines.  Research began in 1999 when a group of professors from Seoul National University of Technology realized that long before the world runs out of wind it will deplete its oil reserves and its available land.  The BEL HP/VAWG addresses these two issues by introducing a 10MW output capacity per unit, wind powered generator which has a footprint of less than 3 acres of area. Innovations incorporated by BEL in the Vertical Axis Wind Generator have increased the overall unit efficiency of the VAWG to approximately 46%.  Computer models and wind test simulations have confirmed the output density and the highest efficiencies in the industry.  This has been accomplished through some of the following BEL innovations:

The above are but a few of the noteworthy features that make the conventional VAWG  into the BEL Horizontal Plane (HPWG) Wind Generator.  These value added innovations have the effect of:
