The WES30 is a durable and reliable midsize wind turbine that
requires little maintenance and has a long life expectancy. The
robust mechanical design of the turbine dates back to 1983. The
electrical part (power conversion and control) has been fully upgraded
since 2005 with the newest technology available. Key to the successful
WES30 design is the well balanced combination of technology with
• Two bladed rotor with passive pitch.
• A-synchronous generator.
• IGBT converter.
The WES30 does not need motors and/or computers driving the
pitching or flapping angle of the rotor blades. In the WES30 all blade
angle and pitch adjustments are handled by a 100% mechanical control
mechanism that uses proven spring and suspension technology. As a
result the position of the WES30 rotor blades is constantly optimized
for the actual wind conditions. This is preferable, since wind is not
constant not even on heights. The flapping technology of the blades
reduces significantly the loads on the whole system of blades, rotor
and gearbox, reducing the wear and tear to a minimum. The system works
a bit like the springs and suspension in an car. Regardless of the
road conditions, the springs and suspension make sure contact between
a car and road is optimal.
The only electromotors in the nacelle of the WES30 are the two yaw
motors. The yaw motors will steer the nacelle in the wind for maximum
performance or steer the nacelle 120 degrees out of the wind (parking
position) when the system is stopped.
The WES30 generates electricity using an a-synchronous generator,
the electricity is passed on to the grid through an IGBT converter. As
a result, even short fluctuations in wind speed are used to generate
electricity. At all times the WES30 controls what frequency is offered
to the grid. The WES30 is designed to deliver its electrical energy to
any (weak) grid and can even improve the local grid.
Overall the WES30 is a high performance, robust and reliable wind
turbine that uses fluctuations in wind speed to produce even more
electricity and has a mechanical design that reduces significantly
forces and loads to tower, bearings, gearbox, rotor and blades.
Because of this the WES30 has a long life expectancy and needs little
and simple maintenance.
The combination of successful mechanical design and state of the
art IGBT technology make the WES30 a high performance and extremely
stable platform that outperforms any other turbine in its class.
