WIND CONTROL is a special device for control of wind turbines (WT). WIND CONTROL ensures generator control and delivery to the distribution power grid.

Features:

WIND CONTROL 400 example

Monitoring:

WIND CONTROL continuously monitors and controls:

Power maximization

Power maximization function of WIND CONTROL automatically adjusts generator frequency to the actual wind speed, thus maximizing generated power of WT.

Active power

WIND CONTROL is equipped with transistor based inverter on the grid side, which allows the delivery of active power only (adjustable power factor) to the power grid.

Enclosure design

WIND CONTROL is delivered in enclosure. Therefore it is possible to add any other components required for wind power plant operation.
