Mechanical Seals Manufacturer In China

Although the wind power development has made great achievements, but the wind power industry in China is still an infant industry that is still at the initial stage.” New Energy and National Energy Board, deputy director of renewable energy, said Shi Lishan, the current the country’s total wind power installed capacity of 800 million kilowatts of electric power is still very low weight, power generation, the proportion of total generating capacity of less than 0.5%.

Impressive scale wind power development, but problems in the development of more and more prominent. The first is the installed capacity is large, but electricity is still very low, efficient power generation time is short, do not create an effective supplement to the power grid, can not form a stable output power grid; followed by the wind turbine grid stability, there is no guarantee, especially in the wind Electrical large-scale grid, the grid impact and damage is very serious and will inevitably lead to network problems; there is a high failure rate, maintenance costs of large wind turbine is no guarantee of safety. These issues have become the wind power industry in the face of important issues.

Europe and the United States, wind power is a decentralized network used in a way, these countries are relatively small-scale wind farm. When the wind speed and wind direction vary greatly, the wind turbine unstable, unable to meet and network conditions, this time off-grid wind turbine at any time; wind turbine stable, but also the network at any time, and the power grid in several European countries are networked, a strong power grid will not have much impact on the power grid.

In China, large-scale grid used in a way, China’s wind energy resource-rich regions are mainly distributed in the northwest, northeast, north of the “three north” region and the southeast coast. Currently in the “Three North” planned six 10 million kilowatts of wind power base, but these areas is relatively weak grid areas, the grid of wind power is facing overwhelming problems. At present countries have to start planning for smart grid construction, but because these areas are in the end power, capacity, poor regulatory capacity, it is difficult to withstand the impact of changes in the wind TVU capacity.

China’s wind power project is also faced with numerous technical difficulties, are still unable to overcome, which makes the majority of the project is idle, such as Inner Mongolia, last year’s total installed capacity of Zhuozi County reach 10 million kilowatt hours and sent wind generator the system due to the capacity of poor grid, power plants the electricity generated in the local digestion and could not finish, also send outgoing not go out. Nearly half of the wind turbine is idle, only 2 / 3 of wind power on the Internet.

wind generatorsstation Is not anywhere Jianzhan a. It must be built on the wind resource-rich areas. Namely, wind speed, sustained period of time. Wind resource size and topography, geomorphology related to Yamaguchi, islands are often the preferred address. If the new strong up to board the city, the annual average wind speed 6.2 meters / sec, Inner Mongolia Huitengxile, the annual average wind speed of 7.2 meters / sec, Jiangxi Poyang Lake, the annual average wind speed 7.6 meters / sec, Hebei Zhang North, the annual average wind speed 6.8 meters / sec, Liaoning, Donggang, the annual average wind speed 6.7 meters / sec, Guangdong, South Australia, the annual average wind speed 8.5 meters / sec, Fujian Pingtan Island, the county average wind speed of 8.4 m / s, Pingtan County haitan Island, the annual average wind speed of 8.5 meters / second, the annual number of hours of wind power generation to 3343 hours, for the present of China. (The above figures quoted from the “National Information Center ofwind turbine generatorgrid-description”). The South China Sea’s Spratly Islands, the island for more than one year of continuous strong winds are blowing 160 days 6. Such a place in our country there are many, many more are waiting for us to explore, discover.

At present, whether international or domestic, Daxing the momentum of rapid wind turbines. Japan’s current day to 25 million kWh of wind power in 2010 to reach 3 million degrees. The United States will soon be the construction of the world’s largest wind power generator station, along the Oregon and Washington State border to build 450 wind turbines with a total generating capacity of 300 MW. In addition to the city in China’s wind power up to board the sidelines of Pingtan in Fujian in 2004 with 780 million to build 100,000 kilowatts installed capacity of wind power stations. In Guangdong, South Australia, at home and abroad Ju-ho have invested in turbine generator , a total investment of 2.707 billion yuan. Total planned installed capacity of 275.5 thousand kilowatts. Beijing Guanting wind farm planned in October 2005 started the construction of annual power output of 10 billion kWh of wind power stations, is expected to completed by 2006 grid.

“Domestic wind power plants have launched most of the image works.” Miao Wei, vice minister of Public letter on the 7th regiment taking part in a panel discussion that really surprises people in Hubei, in his view with my sand deposited by wind and sand abrasion of wind generator equipment, large, launched Too many wind power projects substandard conditions of our country.
Miao Wei said that in foreign countries where the wind is not sand, for example, the ocean wind. China is a place where the wind there is sand, sand for wind power generation equipment wear and tear a lot. Now wind power blower should be 20 years of life, but if there is wind and sand erosion of life also did not reach 20 years. “In another five years, life will certainly be problems, especially in Gansu that 10 million kilowatts of wind power plant-level image of a typical project.” Miao said.
On this topic, Miao Wei talked about the layout of the status quo of China’s electricity, said the focus of the energy distribution should be the supply-side and use the side to achieve a balance. The status quo is pulled low energy operation of high energy. Miao Wei, for example, was originally Hubei Hydropower advantage, the Three Gorges power should be more use to stay in Hubei Province, this is the best clean energy. However, but now they have transported to the eastern part of Hubei, Xinhua District, Hubei, and from around the buy-coal to Hubei, triggering a series of effects, “Henan is not good enough, they then Shanxi, Shandong, Xinjiang, and even to transport coal. To conduct a nationwide travel, and half for the national rail freight transport coal. This is what the logistics cost, how much wasted. ”
According to reports, Gansu Jiuquan wind power base of 10 million kilowatts class in August 2008 in full swing, indicates that China has formally entered the building, “Wind turbines of Three Gorges,” the construction stage. According to meteorological department the latest wind energy assessment results show that the total reserves of Jiuquan wind energy resources of 1.5 million kilowatts, can be developed for more than the amount of 40 million kilowatts, can make use of an area of almost 1 million square kilometers.

Danish Energy Agency released the latest data show that in 2009, the Danish wind power to restore growth and full-year land-based wind power production increased by 97 megawatts (MW), the highest since 2002, offshore wind power production increased by 237 megawatt (MW).

According to the Danish Energy Agency statistics, the Danish wind turbines accounts for about 20% of the total electricity consumption. Danish Wind Industry Association has previously set forth their goal, that is, by 2020, wind power accounted for 50% of the total electricity consumption. Although Denmark has long been considered to be the world’s leading wind power technology-exporting countries, but in recent years has experienced a low growth period. Danish Wind Industry Association of the Energy Department has announced
