Europe is the largest recipient of wind power
To Washington on April 29 (Xinhua ZHANG Meng-jun) At present, wind power has become the fastest growing power industry. Europe is the largest recipient of wind power. Expected in the next 10 years, the European wind power will account for the total generating capacity added 1 / 4. Wind turbines are built on the coast, its wingspan even more than one basketball court. Today, the largest commercial wind turbine has a wingspan of 104 meters, generating power up to 03,600 kilowatts, enough to power 1,000 U.S. households. In February, “the German power system,” in Hamburg near the start of a demonstration wind turbine, generating power of 0.5 kilowatts, and its wingspan of up to 126 meters. U.S. General Electric Company has designed 70-meter blades, which span 140 meters of wind turbine generators. Although GM has yet when it plans to build such a large-scale wind turbine, although it is believed that the size of wind turbines generating power of 07,000 kilowatts. 100 wind turbines that generate electricity power is 70 kilowatts, the equivalent of a large conventional power station. U.S. National Wind Technology Center Director Sirui homes, said: “From the economic point of view, the longer the turbine blades, cost-effective as possible. Wind power industry and federal researchers aim is to build 3 cents per kilowatt wind farm . At present the cost of wind power at 4.5 cents. 3 cents per unit cost of wind power, will beat 3.5 cents per kWh, the most efficient oil burning power stations. “Sirui House, said:” If the study went smoothly, these giant wind turbines in 2012 for large wind power plants. However, the University of Massachusetts Wind expert McGovern noted that relying on such a large wind turbines is not without risk. the larger turbines, if one of them station failure, the cost is high. McGovern said: “Sooner or later they will be made great, then, they lost all their assets. Development of power generation from 0.5 to 07,000 kilowatts of wind turbines, is still immature, so that they can not reliably estimate the cost of deployment. “Last year, the global wind power capacity by 20%% growth rate. Network operators are continuing to wind power to enter the existing grid. But because wind power production influenced by the climate, which is a huge power grid challenge. grid electricity supply and demand must balance. If the wind power generator and hydropower Yi Qi power supply, you can address the issue. For example, last year, “Canadian Shuidian Development” company, in the southern province of Alberta Shui Dianzhan Fujin built by a Feng plant. network management personnel to resort to sophisticated wind forecasting, to help them plan ahead to make power, if necessary (wind-hour), procurement from other power sources other power.
