Design and Principle of Operation
The wind dam represents a system of radially positioned, narrowed towards the wind turbine wind-conductors 1 which are formed by the radially or tangentially positioned in relation to the outer edge of the wind turbine 2 partitions 3. The partitions are tree-plantings.

Using of treeplantings in place of partitions allows to reduce substantially the expenses for wind dam construction and, in the last end, to reduces the self-cost of produced electric power.

The operation principle of the device is as follows. The wind current passes through the wind-conductors formed by the tree-plantings and is concentrated on the rotor's blades. And according to the familiar Bernoulli's principle the wind current is accelerated.

Its operation principle is similar to that of the hydroelectric power station dam. Just as the hydroelectric power station dam collects water current's energy on the turbine's blades from the large area, so the "Wind dam" offered by us collects air currents' energy on the wind turbine's blades.

Partitions may be of different length. Since the maximal efficiency of the wind electric power plant is possible, if the wind speed range is rather narrow, it is desirable to narrow this range.

It is possible at the wind concentration stage. The average annual wind speed differs from direction to direction. Therefore, if the length of the wind-conductors is in inverse proportion to the average wind speed, the wind current will be more steady. In this may the higher efficiency of the wind electric power plant is achieved.

In areas with winds of pronounced directivity (breezes, mountain and valley winds, monsoons), the wind dam may include one or two wind conductors.
