Shanxi changzhi city in the county, on the outskirts of, impressively stands over 70 meters of transmission tower. Starting from here, is a longitudinal cross YuE jin 640-kilometer long dragon domestic silver of the first uhv transmission project 1000 kv southeast shanxi-nanyang-jingmen uhv communication experiment demonstration project.glue gun This is the highest in the world, the technical level running voltage is the most advanced, our country has completely independent intellectual property rights of the ac power transformer engineering. It's put into operation, pulled open China power into the history of ultra-high voltage times curtain, achievement is also the state grid corporation of China's future energy drawn grand blueprint for sustainable development.
Energy distribution obstructionglue stick , call high pressure
Our country's energy and productivity layout a insurmountable between the gulf: most of the coal, water power, wind power concentrated in the northwest, but more than two-thirds of energy demand concentrated in the Midwest. Load center and resource center from far away, the western coal had to go through a long journey vehicles are flowing to the east, the inevitably leads to atmospheric pollution, and environmental destruction......
To solve the transportation problem have a welcome antidote: will the west coal resources into power again through uhv export to the east, not only reduces the cost of using coal and also reduce the pollution of the distribution of the energy along the natural conditions make the national grid company uhv transmission technology as a way to change the energy development the inevitable choice.
Uhv grid, it is to point to 1000 kv ac and dc power transmission network plus and minus 800 kv. It has a long distance, high capacity, low loss and save the land resources and other characteristics, called the world power grid construction "mount Everest". "1025" plan for clearly put, development and ultra-high voltage large capacity and high efficiency and long distance transmission technology advanced. The move marks the ultra-high voltage construction has increased to national strategy.
So far this year November, 1 million volts southeast shanxi-jingmen high voltage ac transmission test demonstration project already accumulative total transmission 26 billion kilowatt hour, powerful easing central China area of seasonal electric contradictions.
Smart grid bring intelligent life
November 25,, the electric car Sue the Shanghai and hangzhou inter-city interconnected demonstration project acceptance work completed. Project involves the Shanghai, suzhou and hangzhou highways between five to nine intelligence service area, filling in all through the acceptance of the power station, marks China's first electric car across provinces inter-city Internet project completion, and has put into operation conditions.
Installed miniature sensors the plug, you forgot to turn off the TV and desk lamp and appliance, can help you turn off the electric appliance in the near future, the equipped with the motion sensor "clever" plug may as all electrical appliances standard, equipped with to each machine appliances.
Big to car battery charging station, small to "smart" plug, new intelligent sensor technology is applied to the power grid and development step by step in the practice of the power of the people.
The state grid corporation of China for 88% of the land in approximately 1 billion people power supply. Company general manager LiuZhenYa announced that in the next five years will plans to invest $250 billion in our country's basic built strong intelligent power grid. By 2015, the national power grid can support 90 million kilowatt wind power and 8 million kw solar power of access and XiaoNa, guarantee the application of 800000 cars electric cars.
Clean energy lead future
"If you don't solve the wind generator power output effective XiaoNa, wind power development and utilization efficiency and economy will be significantly reduced." Gansu province power company wind power, director of the center WangNingBo said.
ZhangBeiXian in hebei province, the dam region has short winter sunshine wind, fully wind failure, summer sunshine sunshine strong wind speed during the day, night wind speed and small big weather characteristics.
