Dealing with Low Temperatures

Actually, low temperatures themselves don't negatively affect the Sirocco energy wind turbine. The issue might be the snow or rain going along with below-zero temperatures. The key elements that can freeze are the guide track and the blades.

Let's talk about the track first. We need to understand that the track consists of high-precision metal rails with a well-polished surface. We have special metal scrapers on the chain of carriages, which are 0.3 mm away from the track surface. When a layer of ice appears on the metal, the scrapers remove the ice, and the guide remains clean. If icing occurs when the unit isn't working, the start system is activated. The electronics start all the generators in engine mode to forcibly scroll the carriage chain, and the scrapers clear the ice. After the blades have reached the required speed, the starting system is turned off, and the wind turbine continues to operate independently in normal mode.

Talking about the icing of the blades, we should mention that the movement of the blades is somewhat different from the movement in the traditional vertical or horizontal wind turbines. We have a combination of linear and rotational motion of the blades. This allows, if not completely avoided, significantly reduce the degree of icing of the blades, because when moving from a linear to a radial area and vice versa, the bulk of snow and ice will fall out from the blades.

Of course, now we are not talking about extreme levels of icing. If the turbine has to work in more severe climatic conditions at low temperatures, its complete set and functionality must be adapted. First, instead of aluminum blades used in typical turbines, we'll have the blades made of fiberglass with a special coating. Also, an additional option is to install a rotary brush (as in the snow cleaning technique). In the off position, it will be located vertically in the space between the two rows of blades. In the working position, it will be pushed forward and lowered horizontally. The starting system turns on the generators to start moving the blades and a separate motor of the brush itself, which begins to rotate and alternately clean the surface of the blades.

Apart from that, we will need a spare battery with a larger capacity than standard, different electronics firmware that should match the wind speed, and current generation to record when the installation began to generate less energy than it should.

As you see, we have it covered. So... let it snow, let it snow, let it snow :)
