subject: Uhv To Find Solutions For The Wind Power [print this page] For clean, renewable energy access difficult problems April 19, the State Grid Corporation issued in Beijing, "Green Development White Paper" for the plight of his prescription: high voltage power grid construction by special fast lifting the assimilative capacity of the new energy consumption is expected to 2020, will eliminate 462 million kilowatts of clean energy is satisfied. By then, the wind difficult issues will be resolved online.
Nearly 1 / 3 of wind turbines idle wind power development experience, "multi-car less" awkward
Jiuquan City guazhou, Yumen and Subei Mazongshan desert region known as the "World Wind Library" is known, however, due to the Jiuquan wind power base away from the grid and load centers, consumption and can be sent as a constraint large-scale development of renewable energy a major "bottleneck." Similarly, has the most quality and relatively stable sources of Inner Mongolia, wind, wind power, made a call can not enter the end-users, most of the fans jumped in the air at night trough outage, suffered "multiple small car" embarrassment.
Recent years, wind power developed very rapidly, far beyond the original planning expectations. From 2006 to 2009, China's wind power installed capacity to double-type growth for four consecutive years. According to the China Electricity Council statistics, in 2009 the national wind power installed capacity reached 16.13 million kilowatts. State Electricity Regulatory Commission, "Wind power development in China Investigation Report" shows that difficult issues such as send, general operating wind farms across the country difficult, or even a loss, there are nearly 1 / 3 of wind turbine is idle.
Rich wind power resources in the Northwest, Northeast, digestion can not afford to add a large number of local wind power, the power shortage can only be sent outside the east and south China, thousands of kilometers away, what would he get? How to send?
Industry experts point out that the current problems to be solved not just come clean energy to fat, is more important is how intensive and efficient, "free to go."
The development of wind power throughout the power system into a unified plan to prevent "wind of the Three Gorges" as "lame" project
To promote wind power in China's rapid development and construction of 10 million kilowatts wind power base, to create "wind of the Three Gorges," Today, the Three Gorges hydropower electric power consumption of the experience, perhaps for Mirroring.
Three Gorges Project's success in large part due to "the whole country" concept, from the start emphasized the Three Gorges hydropower, "free come, come, the lingua franca of" target. After years of repeated, full research and comparison, the final choice of the central, eastern and Guangdong as the Three Gorges hydropower Absorptive area. Three Gorges hydropower characteristics, the monthly distribution of the Three Gorges power to Henan, Hubei, Hunan, Jiangxi, Shanghai, Jiangsu, Zhejiang, Anhui, Guangdong and other provinces and cities 9. Construction of Three Gorges power station construction while supporting the appropriate power transmission project, to ensure the smooth progress of the Three Gorges power consumptive.
Other major countries and the world to develop new energy sources is different, our primary energy distribution is very uneven development of productive forces, Wind Energy , Large-scale concentrated solar energy development, small-scale local power grid, can not be used locally, require long-distance transportation, a wide range of consumers satisfied. In accordance with the "big base building, into the bulk power system" in the layout, my plan in Inner Mongolia, Gansu, Hebei, Jilin, Xinjiang, Jiangsu coastal provinces such as construction of seven wind power base of 10 million kilowatts. 2020, China's clean energy will account for 28.4% of the total electricity installed capacity. Among them, the wind power installed capacity of nearly 100 million kilowatts.
Wind power and other fundamental difference between conventional power lies in its randomness and intermittent generation characteristics, so the large-scale wind power grid of the power system peak shaving, FM, safe and stable operation and so on greater challenges . To avoid the currently emerging wind power generation after the problem but can not be fully learn the successful experience of the Three Gorges Project, the development of wind power into the power system for unified planning, rational distribution of peaking power and inter-provincial power grids, and promote the sustainable development of wind power.
National Grid Energy Research Institute Zhang Yunzhou that, if left alone wind power planning and power planning gap, "Wind Power of Three Gorges" will become a "lame" project.
Much longer transmission distances require more power sends power of new energy-intensive Call of UHV
"Wind Power of the Three Gorges," the outgoing can learn from the experience of the Three Gorges Hydropower, but this requires a more powerful network, because transmission distance significantly longer, and 500 kV grid is now insufficient.
A famous expert on electricity, the State Grid Corporation of India deputy general manager of Shu Biao shout: this scale can only rely on electricity to be sent outside the higher voltage level can be large-scale, long-distance transportation of special high-voltage grid to achieve.
