Wind power units 's protection of rotary type in unfavourable climate conditions

Abstract

Transition to alternative energy sources is a universal tendency and it is realized with broad political support of many countries, including in the Republic of Kazakhstan. In this regard there is a problem of use of the power equipment in unfavourable climate conditions. Contribution of wind power plant (WPP) in winter time in Northern, Central and East Kazakhstan is fraught with very serious consequences. There multi-day blizzards (snow-storms) leading to drift by a sleet of open surfaces of the device with the subsequent formation of a dense snow and ice armor are frequent, such as, it happens to WPP. At big frosts freeze through bearings, as a result of WPP fails up to destruction under the pressure of a wind. Below it is considered how this problem is solved on the example of wind driven generator in Kazakhstan.
