Mechanical Seals Manufacturer In China

The first half of this year, our province will be the first wind farm started in Bryan. The wind generator plant is located in Lai’an leading posts at the end will power. Shou County, Wangjiang, Susong, everlasting, etc. has entered the wind power projects are planned and will gradually start building.
In addition to using wind energy, the province will also speed up the straw power plant construction. Currently there are seven straw power plant in our province, according to plan, the next five years, our province and the number of straw power plant will reach about 30. Provincial Energy Agency relevant person in charge of building a straw installed capacity of 30,000 kilowatts of power each year will consume 20 tons of straw, so that less than half the province of straw can be converted to electricity use.

In recent years, China’s wind turbine machine of supply and demand reversed, the average profit rate to accelerate to close.
China’s wind resources from the state and has developed the extent that wind power industry still has much room for development. It is estimated that over the next two to three years, the demand on the wind turbine will maintain rapid growth. Wind power demand growing rapidly, faster productivity growth.
Based on the industry leading manufacturer of production statistics: domestic wind turbine capacity in 2009 has significant surplus: in 2009 and 2010, domestic wind turbine requirements were 812 and 10.56 million kilowatts, while the country only a local wind turbine manufacturing business capacity will reach 1200 and 17.25 million kilowatts. Currently, wind power capacity in excess of the situation, many companies have to find a way out of international markets, and this could lead to the integration of the entire industry.
At the same time, wind power machine as a reversal of supply and demand, wind power prices is inevitable. Recently, at the national wind power concession bidding, from the golden wind technology companies released data shows that wind turbine prices have shown a significant decline. Rapid decline in the price of wind power will lead to machine speed to the average level close to the margins.
Before 2008, due to wind power machine in short supply, the shortage of key parts, the whole prices have been strong, and also a slight upgrade. After reaching a certain scale, the whole manufacturing profitable; domestic wind power industry, auxiliary components in the initial stages of failure, some parts such as generators, main bearings, gear boxes, electronic control, and even leaves the majority of the need to import the upstream parts manufacturing Business also enjoy huge profits; and wind farm investment as high wind turbine prices, government subsidies are limited, only at the edge of break-even.
Since 2009, as machine supply increases boost the Guoneichanye supporting Zhubu perfect, and some machine parts such as generators, gear boxes and leaves the price Zhu Jian Deng to a reasonable level of profits Zhexie products tend to average Hua; wind farm operating as machine prices, financing costs and other factors, profit margins are increasing. Long Yuan Electric Power recently successfully listed in Hong Kong, China market shows that capital markets are increasingly optimistic about wind farms operating in the field.
Although the wind power industry, increasing competition, but in 2010 the world’s rapidly growing wind power industry will continue to give wind generators industry in all aspects of manufacturing opportunities. Materials, components, machine manufacture, and operation of wind farm-related company will benefit.
Concern is the domestic market will be industry leaders focused. Although the machine market is facing overcapacity, but this is precisely the industry leading business integration opportunities. Role in policies to promote and market, the domestic market will gradually to the east wind technology electrical and gold concentration of leading enterprises.

The Albanian state news agency reported that 11 wind energy development at the seminar, A National Renewable Energy Center for the news announcement and said it was A wind energy development in the area of the first attempt, will A renewable energy development play a significant role in promoting.

It is understood that wind generators this will build the power plant is located in the southern border of Adrar Assi, by the state funded the construction of electricity and gas companies. Production of energy will be incorporated into the local power grid.

The report also said, A research institutes have been completed Bejaia province, Sétif Province Bordj Bou Arréridj northern provinces such as wind energy environmental studies. Currently, Algeria is still relatively low level of wind energy development and utilization of the country is only 0.7 MW of wind generation capacity.

Algeria in North Africa and the Mediterranean coast, an area ranked second in Africa, oil and gas industry is the pillar industry of national economic development.

April 15, CSR Zhuzhou Electric and Goldwind jointly established the “National Wind Power Electrical Engineering Technology Research Center Laboratory of” unveiling ceremony, Goldwind Science and Technology Wuhan Iron and CSR Zhuzhou Electric together for the “National Wind Power Engineering Electrical Research Center “inaugurated.

In parts of China have been tense due to coal when power cuts occur in the grasslands of Inner Mongolia, a huge windmill seat electric power in the channel because of poor and stall.

Recently, this reporter from the Inner Mongolia Electric Power company plans officer that since last winter, Inner Mongolia grid (excluding the eastern four-Union City) have access within the installed capacity of 4.302 million kilowatts of wind power. In the daytime peak, Inner Mongolia Power consumption can be satisfied all these wind turbines, but the trough electricity at night, due to the heating unit to ensure the operation of thermal power, had to abandon air fan stops and the 320 MW wind turbine can not contribute to the proportion accounted for 80%. The night wind is the largest grassland, the most stable of gold for power generation.

Difficult to access a restricted wind power

“This winter, Inner Mongolia, a large area of abandoned wind turbine is very serious.” Zhang Fusheng, general manager of Inner Mongolia Electric Power Corporation, said in an interview, as Inner Mongolia’s wind power can not be incorporated into the national grid, wind power can not be completely digested in Inner Mongolia, to the north and other areas and can not get electricity.

According to Zhang Fusheng introduction, Inner Mongolia Power Grid by optimizing the scheduling, daytime wind power are able to run at full capacity, but the night after the trough in order to ensure urban heating, wind power had to take measures to abandon the wind. Inner Mongolia Power Grid during the night after the minimum load (including to the East) of about 12.3 million kilowatts, of which thermal power accounted for Heating Unit 12 million kilowatts. To ensure heating ensuring people left margin of wind power capacity has been tiny, wind power can not meet the requirements of full access. Current requirements and network operation in Inner Mongolia Wind Power capacity has been accounted for the highest power supply load 27%, far exceeding the capacity of Inner Mongolia Power Grid (China’s Inner Mongolia Power Grid Power Research Institute demonstrated the capacity of wind power 8% to 10%).

For enterprises, the loss suffered particularly severe. According to State Power Long Yuan Qi, general manager of the new energy company introduced the next life, winter, they Wulanchabu Phaeton Schiller Prairie Wind Farm, has no power to send, there is not a high spirit, had to give up the wind at night direct economic losses have reached 80 million yuan.

Jingneng International Yueheng Fei, said, Beijing will have been put into operation in Inner Mongolia had 700,000 kilowatts of wind power, due to western Mongolia grid Absorptive not too much wind, only to abandon the wind fan stall. From last winter to New Year’s Day 2010, the company has lost 180 million kwh of electricity, equivalent to a loss of more than 100 million yuan.

When reporters learned in the investigation, the present to invest in wind power in Inner Mongolia has more than 60 companies, every business on the transmission capacity limits of wind power concerned. In their view, if not resolved the issue for delivery of wind power, renewable energy construction in China, especially wind power will be badly hit.

Delivery of wind power to solve pressing

Affected by the cold winter in 2009, our multi-provincial power cuts, the railway transport capacity tight, coal carts were blocking roads a day 10 hours, rising coal prices, but the Inner Mongolia Wind Power, a large number of idle thermal power, but not lack of delivery electric region. Inner Mongolia Wind Power Development for gridlock, Inner Mongolia Autonomous Region Director of State-owned Assets Supervision and Administration Commission and the Soviet Union that the construction of West Inner Mongolia Power Grid for delivery as soon as possible channels to solve the Inner Mongolia Wind Power development and achieve national clean energy shared fundamental way.

Inner Mongolia is rich in wind resources, the cost of the electricity price is also an advantage. Hours of wind energy in Inner Mongolia, wind power costs less than 0.46 yuan full / kWh (south thermal power electricity price more than 0.52 yuan / kWh), wind power is about 0.1 yuan per kilowatt-hour of compensation available, coupled with carbon sequestration trade and investment in wind power enterprises in Inner Mongolia, the enthusiasm continues to climb. National Development and Reform Commission has sent two special study group in-depth site visits in Inner Mongolia, and issued a circular calling for State Grid Corporation come up with in the context of the national electricity market, wind power consumptive programs.

Su and recommendations, construction of wind power in Inner Mongolia can learn from the experience of the Three Gorges, the establishment of the National Electricity Market Absorptive wind mechanism. 10 years ago, in planning the construction of the Three Gorges hydropower station, the channel sent in advance planning and design to ensure reliable electricity at the same time the Three Gorges hydropower station sent into production. In view of large-scale wind power development, wind power transmission project brings together long distance, large investment unit the actual situation of the Three Gorges hydropower can cut a piece out of funds to build “wind of the Three Gorges” and the external transmission channel. Or the use of national reconstruction and electrification of the rural power network introduced in railway construction support policies for the introduction of wind power tariff policy sent debt service.

Zhang Fusheng that wind power development at the national power grid (including the China Southern Power Grid) level of market acceptance of wind power, under the overall co-ordination plan, provinces and regions in the electricity market acceptance of wind power must stay out of the space.

This is a Feb. 27 shooting of the East China Sea Bridge wind farm at sea fans. The same day, China’s first and Asia’s first large offshore wind farm – all of the East China Sea Bridge wind turbines farm of 34 wind turbine installation success.

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.
