Wind turbines

Turnkey systems for wind power stations

The main targets of a wind power station are to maximize efficiency and performance by optimizing the wind incidence angle on the vanes and to guarantee a steady rotation speed. The control technology of the adjustable pitch propeller plays therefore a key role thanks to the important reduction of the time needed to reach the production peak, which is kept constant even in presence of a variable speed wind.

Being a worldwide leader in the energy sector thanks to the several projects in the production of solar, geothermal, hydroelectric, gas-turbine and steam-turbine energy, Duplomatic Oleodinamica is in a position to offer a turnkey system representing the most comprehensive and efficient solution to problems related to the generation of wind energy.

The system is made up of a power unit designed to generate the flow rate necessary to the movement of the hydraulic axes; three servo-actuators controlled by proportional valves with digital integrated electronics and synchronized through a field bus for the control of the vane position; two groups controlled by proportional valves with digital integrated electronics for the control of the rotor and holding brakes.

The result is an integrated platform capable to offer important advantages in terms of efficiency and safety as compared to the traditional electromechanical systems.

Accuracy in synchronism and efficiency
The servo-cylinders automatically vary the vane position according to the wind speed and direction thus steadily maintaining the generator at its highest performance level; the accurate synchronism of the position of the three vanes is ensured by proportional valves with stateof- the-art integrated electronics and reduces to the minimum the mechanical stresses on the
structure.

Safety
In case of faults or excessive wind speed, the vane return to the safety position is guaranteed even in case of power drops: the sensors placed onto the safety valves and the control unit allow the control room, wherever it may be, to fully monitor the system functioning conditions.

Compactness
Thanks to its feature of making up the high power density with the extremely reduced dimensions of its components, the system designed by Duplomatic Oleodinamica represents the ideal solution for the installation within the limited space available on the wind towers.
