Siberian Branch of the mobile operator "MegaFon" reported that in the Krasnoyarsk Territory started using the remote base stations, power which is produced using wind power. Special vetrogeneratornye installation provide about 85% of the power supply to the site and allow you to save more than 300 000 per year per one base station.
As the operator, a feature of the Krasnoyarsk Territory, Khakassia Republic and some other regions of Eastern Siberia - long distances between settlements. To provide mobile communication roads and railway lines, service provider often requires the antenna-mast structures and the base station away from sources of supply. These communications facilities are equipped with diesel generator sets, working 24 hours a day.
In order to reduce the cost and burden on the ecology of the Siberian Branch of OJSC "MegaFon" has started a project on the remote base station equipment Krasnoyarsk vetrogereatorami. Special plants with capacity of 6 kW for about 85% of the power supply. With enough wind generator is not only fully covers the needs of telecommunications equipment in the power supply, but also allows to store excess energy in batteries. The remaining 15% of the time of the base station occur in calm weather, during which the station is powered by a battery and a standard diesel generator. In the long calm, the base station can work in standalone mode without refueling around 2 weeks.
Another feature of this structure is on a separate assembly vetroelektrogeneratora mast structures located in close proximity to the "tower" base station itself. As stated in the company for the project were applied know-how in the management of the entire system, for example, to eliminate redundant power converters, which increased the overall efficiency of the hybrid plant. Due to the low speed of rotation of rotor life of the generator is 25 years or more. Similar generators are used in the Arctic stations, which indicates a large margin of safety in the work at subzero temperatures in Siberia.
