Off-grid wind and solar powered electricity herders zero energy

August 27 large-scale scientific and meteorological science activities " Climate Change China trip - into XiMeng " Abagaqi delegation came to feel the real life of ordinary herdsman , to understand wind power and  SUNGOLDPOWER solar energy in the grassland everyday applications . With the help of the local administrative office , we enter into a herdsman INNER · its wooden frame home.

Not into the pastoral house, we noticed the house behind a unique equipment. A small windmill spinning hula hula , next to a shiny solar panels. "This is a wind and solar power generation device , all the herdsmen in Abagaqi home are filled with such devices ." Is responsible for the entire A flag to install wind and solar equipment herders hi to us to spring . "Due to the special conditions of sparsely populated Inner Mongolia , electricity and there has been some problems. Herders living in relatively fragmented way with netting electricity transmission , power loss is large, very realistic , so a few years ago there have been many herders no power supply is in the state and now , the use of such devices will be able to solve the problem of herdsmen living power ! "

There are about ten thousand local herders , after three years of efforts the government , traveled A flag sixty thousand square kilometers of land , and now almost every household currently Abagaqi can spend such devices, and each set of equipment of approximately one thousand dollars, so calculated , the government has invested several hundred million of funds to the a flag all herders installed wind and solar -powered equipment.

"The wind electrical power of about 300kw, solar panels power of about 200kw, Calculating this day, the amount of power you can basically meet the demand for electricity pastoral life . Generally, the smaller the winter electricity consumption in summer due to the use of the refrigerator , more than electricity . " Chun Xi said to us , " night wind large wind turbine can generate relatively abundant energy during the day in addition to wind power generation, solar panels also help significantly with the power supply , which is a very clean and efficient way of generating electricity . "

If neither wind and cloudy day how to do it ? Chun Hei took us into the room, next to the refrigerator , we find a two ivory boxes. "This is the equipment of another important components: the dc to ac inverter ." Chun Xi explains, " the 10,000 -volt high-voltage of 220 volts down to the voltage of the equipment called a transformer life , and this happens to be the opposite inverter , is 24 volts power supply 35-220 VAC use power at 600w around . " Here is one of the inverter battery , the output from the wind turbine and solar energy transmitted through the line and stored in batteries , always ensure that pastoralists home electricity demand. "Generally speaking, a battery power loss , it may take two days to impound the battery fills , the system can be controlled manner through automation windmills and solar panels automatically cut off the line , life assurance ."
