Fixed power tariff policy also let developers earn piles. However, by contrast, the market price of the wind generator is falling for, the supplier’s profit margins have been compressed, whole into small profit era.

“At present, our country 1.5 mw fan price is about 3,600 ~ 3,700 yuan/kw, for peak of half.” Shanghai electric wind power equipment Co., LTD, deputy general manager LiuQi said.

Since 2008, China 1.5 multi-megawatt wind generator in the average price of annual 22-23% slower to end of 2010, the average, reached RMB 3900 / kilowatts. Information indicates that at present the east turbine Co., LTD. Offers the lowest quotation, its 1.5 mw unit has fallen to 3,200 yuan/kilowatts of Inner Mongolia, and in “a project can DongQi 2 megawatts in bidding for the model, is quoted an affair for 3650 yuan/kilowatts.

Guodian combined power technology Co., LTD, deputy general manager of truth, in SunLiXiang market now, fan price system of enterprise must rely on the size advantage won’t lose money, “individual fan supplier so-called earnings, often only considered the equipment procurement and manufacturing costs, but ignore the later service and maintenance work.”

MingYang wind’s chief operating officer HaoYiGuo argues that, excess capacity is current market irrational competition caused one of the main reasons of investors in recent years, “wind power generators equipment manufacturing swamp in speeding up Chinese wind power industry, the development of domestic, but also lead to overcapacity wind-power equipment manufacturing problems increasingly prominent.”

The learned, 2010 new wind power an installed capacity of nearly 2,000 million kilowatts, only sinovel, DongQi, MingYang junwu, five companies combined power and the productivity, more than the above capacity. Meanwhile, Denmark, Spain tower si song weisman, American beauty sayin international fan manufacturing giant GE in HuaJianLi production base in the fierce market competition, wind power before.

Facing swept over the whole industry profits crisis, as the machine parts suppliers and business strategy partner, also in hot water.

Chongqing branch kay avant-garde wind power control equipment Co., LTD, chief technical experts, li hui, said: “the enterprise cost pressure parts suppliers must be transferred to, and parts of upstream, such as electronic enterprise device market purchase price basic transparent, and stable, so we will undertake the most prices fell under pressure.”

Another domestic first echelon converter enterprise controller also said although the 2011 enterprise orders, but a sharp increase in profit decline, currently only but in volume to support. The most important is, in the long run will also affect enterprise future r&d investment.

Not optimistic, industry experts generally think that, in the current market environment, price competition will also lasting exists, the next three years is probably wind turbine generator equipment industry reshuffle stage.

A total of 28.26 GW of wind power generators had grid connections in areas covered by SGCC at the end of last year.

After adding 16 GW of new wind power capacity last year, or a boost of 62 percent, China had 41.8 GW of capacity, the world’s largest, the official Xinhua news agency reported.

Some Chinese wind generators farms have been working far below capacity since the local grid was unable to accommodate the rising number of intermittent energy sources. Some wind turbines have never been connected to the grid.

The government was considering ways to ensure grid connections for output generated from planned wind power capacity of 90 GW by 2015, China’s National Energy Administration has said.

Must consider wind-driven generator power and storage battery capacity of the rational matching and static period storage can wait for a problem.

At present, wind generators and battery capacity is commonly according to the input and output is equal, or greater than the principle of input output matching. Namely:

120Ah 100W wind-driven generator matching 60Ah battery (2 pieces),

; 2million wind-driven generator matching 180Ah battery (120-60 or 90Ah 2 pieces),

300W wind-driven generator matching 240Ah storage power (120Ah 2 pieces),

750W wind-driven generator matching 240Ah battery (120Ah 2 pieces),

1000W wind turbine generator matching 360Ah battery (120Ah three block).

Practice has proved: if matching battery capacity is not accord with wind generators sends out energy requirements, will produce the following questions:

1, battery capacity too big when, wind-driven generator emit energy can ensure timely to battery sufficient electricity, causes battery often in kui electricity state, shorten the battery service life. In addition, battery capacity, price and use fee will also increase, give financially cause unnecessary waste.

2, battery capacity after hours, can make the battery charging often in state. Because if enough electricity to stop the wind generators’ work seriously affect fan work efficiency. Long-term storage battery charging will make the battery early damage, shorten service life.

Use of small wind power generators, matching appliance also should according to the battery and the matching principle of wind turbine generators. Namely matching of electric consumption of energy and wind generator power output matching. Matching index which emphasized is “energy”, don’t confuse for power.

In selecting appliances, should pay attention to the electricity suppressed requirements, small wind turbines distribution box on the 12V, equipped with special socket, and television sets 24V users, and should in appliances required voltage choose corresponding socket, television should special insert in TV socket.

If you are using ac electric equipment, it must be designated to meet its power requirements “inverter” will change into battery of dc voltage is 220V, frequency for 50Hz alternating currents can use it.

Maintenance personnel can enter the cabin through the wind turbine tower. Left is the wind turbine rotor cabin, that the rotor blades and shaft.

Rotor blades: captured by the wind, and wind sent to the rotor axis. Modern 600 kW wind turbines, each rotor blade measuring approximately 20 meters and is very like the aircraft wing design.

Axis: Axis low-speed small wind turbine attached to the shaft.

Low-speed shaft: the low-speed home wind turbine rotor shaft axis and gearbox together. In the modern 600 kW wind turbine, the rotor speed very slow, about 19 to 30 rpm. Shaft in the hydraulic system for the catheter, to stimulate the operation of the air force gate.

Gearbox: gear box on the left is the low speed shaft, which can high-speed shaft rotational speed increased to 50 times the speed axis.

High-speed shaft and mechanical gates: high speed shaft to 1500 rpm operation, and drive the wind turbine generator. It is equipped with emergency mechanical brake, brake failure for the air force, or the wind generator is maintenance.

Generator: Usually referred to as asynchronous induction motor or generator. In modern wind turbines, the maximum power output is usually 500 to 1500 kilowatts.

Yaw device: With motor rotating cabin so that the rotor is facing the wind. Yaw device operation by the electronic controller, electronic controllers to feel the wind through the wind vane. The figure shows a wind turbine yaw. Typically, the wind changed its direction, the wind turbine will deflect a few degrees.

Electronic Controller: Includes a continuously monitor the state of wind turbine computer, and yaw control device. To prevent any failure (that is, gearbox or generator overheating), the controller can automatically stop the rotation of wind turbines, and through telephone modem to call wind turbine operators.

Hydraulic systems: wind turbines for the air force reset gate.

Cooling Components: contains a fan for cooling generators. In addition, it contains an oil cooling device for cooling gear box oil. Some home wind generators have water-cooled generator.

Tower: vertical wind turbine towers and rotor containing the cabin. The tower has the advantage of generally high because of the higher off the ground, the greater the wind speed. Modern 600 kW wind turbine tower height is 40 to 60 meters. It was tubular tower, it can be lattice-shaped tower. Tubular towers safer for maintenance personnel, because they can reach the top of the ladder inside. Grid tower is that it is cheaper.

Unfortunately, the delay came the gunshots.
Provisional end of May, originally scheduled for earlier this month, China conducted the first round of offshore wind power concession bidding seen. This was the offshore wind power concession tendering second delay. Prior to the delay, the official statement is that “some details of the work yet to be implemented.”
Wind power concession bidding is used since the system began in 2003 in order to determine the electricity price of wind power. Sea wind power concession bidding starts, it means that countries are about large-scale offshore wind power development.
In fact, as early as before the starting gun, coastal local governments and enterprises have been robbed of all power to run trend. They drafted dozens of development agreement framework, dominant offshore wind power resources have been “among themselves.”
Dafeng City, Jiangsu Yancheng China Merchants Secretary wind power industry told the Southern Weekend reporter Kang Hung, although the concession tender has not yet been, but Dafeng City, Jiangsu Yancheng has three wind was about to receive Development and Reform Commission’s approval, or participation in investment companies are the China Power Investment, State Power and Huadian Group Longyuan. The remaining 11 wind generators farm of China Guangdong Nuclear Power Group, China Resources Power Holdings Company Limited, Jiangsu Guoxin Group, the German Solar Industry giants competing for CCE and other objects.
“Investment companies are interested in many, but not every business can get what you want.” Kang Hong said.
Data show that wind farms Yancheng Dafeng City in Jiangsu Province of planning capacity of about four percent more than the total capacity, ranking the first in Jiangsu.
Dafeng is only “Happy Valley Circle Sea” in microcosm.
Dongtai City not far from the Dafeng, also has extensive offshore wind power resources, according to the plan, thousands of East Taiwan 265 Wahe up wind power generators resources are divided into nine winds, which numbered C1, C2 of the wind field will participate in the concession tender.
Allegedly, Guohua Energy has been a local government’s “oral promise”, which will be marked with a wind field, while the remaining eight are essential to determine “who gets.”
At present, the first round of offshore wind power concession projects had “delineated” in the coastal areas of Jiangsu, the project consists of two inter-tidal projects, as well as two offshore projects, the scale of the inter-tidal project is 20 million kilowatts, the offshore project 30 million kilowatts.
Because of this, from the beginning of the year, power companies and equipment companies have distribution Fan of Jiangsu. Macroeconomic Research Institute of Jiangsu Development and Reform Commission as well as Gu Weidong lamented that “for the development of Jiangsu coastal waters offshore wind have to seize the finished basic.” “As a general panic buying,” Kang Hung said, “but these are the intentions of the agreement, or to wait for the final approval of the NDRC.”
Not bad money, bad money?
“These agreements are basically hundreds of billions of items.” Eastern Taiwan by the letter of the Director of Resources Committee of the Southern Weekend Sun Wei told reporters. Currently, participation in offshore wind power investment are basically the “national character head” of the Power Group, the hundreds of billions of investment seems to be only the central enterprises to take out.
As a percentage of the total worldwide installed capacity of not more than 1.3% of the offshore wind power, by the power giants Why favor? In fact, the offshore wind turbines generator concession project has just begun, Internet price has not been determined. Meager profit compared to the current wind farm on land, offshore wind power has a more profitable future is not optimistic.
Clearly, the pursuit of profit can not explain the power giant, the warm wind on the sea.
“Power Group faces the completion of renewable energy quota of pressure.” Guohua (Dongtai) Wind Power, general manager of Central Asia, told the Southern Weekend reporter Joe. For the Power Group, the state’s intention to request more than 5 million kilowatts installed capacity of power plants in addition to water and electricity in 2010, the renewable energy quota of 3% will have to reach 8% in 2020.
“Able to fulfill the quota can not be approved thermal power project, which will lead directly to the Group’s total installed capacity of power do not increase.” China’s Securities analyst Zhang Shuai in the phrase, “Once the total installed capacity will be left behind in the next five major power integration process, the small may be others that have to swallow. ”
If the layout for the offshore wind power is the future development of five major power to eliminate bottlenecks, have been listed or proposed for listing of power enterprises, the offshore wind power is more likely to be in the face of high prices of coal and heavy rates of assets and liabilities of a “straw.”
Five Power Group currently faces generally in the 80% rate of assets and liabilities. “SAC Power Group on such a high debt ratio definitely satisfied.” An insider Guodian said to reporters. Packaging business through the new energy market, access to finance, can certainly reduce the rate of electricity assets and liabilities of enterprises.
Last week, it has spread Huaneng and Datang will consider splitting its business listing of new energy sources, to give a warm response in the stock market after the Tang Dynasty issued an emergency notice to be clarified.
Nevertheless, the power company “misappropriating” the suspect’s query followed.
To the central enterprises listed overseas, first in the new energy company – Guodian Longyuan Group’s new energy company, for example, is quite particular about the time of its listing. October 20, 2009, the company announced that its Longyuan Rudong County, Jiangsu Province, Central, Hong Kong and the Bund on the South Yellow Sea, the two 1.5 MW fans start grid. Two months later, Longyuan companies that issue H-shares listed.
Issue price of 6.26 Hong Kong dollars to 8.16 Hong Kong dollar range, far more than other Chinese power sector.
Since listing, Long Yuan Group, the world’s total market value of wind power company has entered the top three, the total funds raised 17.7 billion. The current share price has risen over its issue price of 10%. At present, Guodian in five major power, the debt ratio is the best performance, the average remained at about 73%, lower than other power enterprises.
“Bundled Investment”
In fact, “borrowing” offshore wind power turbines, more than five major power.
Can be found, with the development of offshore wind field of local government, almost all of the construction of wind power in the generous open industrial park.
Offshore wind energy resources are concentrated in Jiangsu, Nanjing, Huai’an, Lianyungang and other cities, have announced the Bureau of sea fans and equipment, and Yancheng, Nantong, Wuxi, the direct shouted to create huge “wind power equipment parts and components base” or ” Wind Power Equipment Industry Park “slogan.
Jiangsu Yancheng, for example, the city has planned four more than 10 square kilometers of wind power equipment industry park, Sinovel, Goldwind, Dongfeng, SAIC has identified will be settled in the industrial park.
Yancheng City’s development plan in accordance with 2020, the city’s wind power equipment industry will create 10 million kilowatts machine manufacturing capacity and 200 billion yuan sales volume. “Within two or three years, only new fans along the coast of Jiangsu capacity not less than 10 million kilowatts.” A wind power industry analysts pointed out. Last year, this is almost half of total installed capacity of wind power. “Local governments require the same time start the offshore wind farm, wind power equipment company bundled settled.” Sinovel for Yancheng project Jiaojing Li told reporters on the Southern Weekend, in order to seize market share, wind power companies have done a lot redundant construction projects.
It Jiaojing Li estimated that currently, fan equipment at least 30% of new capacity are such “bundling investment.” Obviously, this will further exacerbate overcapacity fan.
However, the local government is also a belly grievances. An Example in October 2009 completed a 20 MW wind power project as an example tidal flats, “this project we have not a cent within five years, we still pay the 60 million.” Kang told reporters Red said. “Do wind farms for local government is really not worth while to do wind power equipment is definitely making money, it is  windmill generators manufacturing, not enjoy the tax benefits and other policies.” Appears in red health, so-called “bundled investment “the motivation behind a very simple, merely that it was a win-win.
The move would indeed bring considerable benefits local governments. Dafeng City in economic development zones and marine economic zones planned for the two 10 square kilometers of wind power industrial park, in accordance with the Party Secretary of Ni Feng Dafeng expected, two years later, the city’s fans in general will reach 10 billion yuan sales volume This is equivalent to nearly half of Dafeng City in 2009 the gross national product.
Offshore wind power in premature?
Chase the Baltic boom upwind power sources, mainly from the government fabricated a staggering blueprint of wind power.
September 4, 2007, the State Council promulgated the “long-term renewable energy development plan”, which states that the total installed capacity of wind power by 2010 will reach 500 million kilowatts, a total investment of about 190 billion yuan. Less than six months, the state reported a total capacity of installed fan was increased to 10 million kilowatts. Today, China’s goal is to reach 150 million kilowatts by 2020.
Total installed capacity of the fan jump target, led the investment enthusiasm of the same jump. Only from Goldwind, Xiang Long Electric Electric shares and other listed companies since 2008, can be an indications of price rise: in November 2008 so far, Hunan Electric shares rose to 332.7%, 229.4% Long Electric, Goldwind 192.27%.
Hiding behind the reality of these data is the lack of wind power in general. January 22, 2010, the state has issued “development and construction of offshore wind Interim Measures,” which is clearly not enough to be the guiding offshore wind power development plan documents.
Even the most basic survey of offshore wind generators resources, are also being constantly revised. May 11, National Energy Board has revised its land, sea and air resources. Among them, than before the census, offshore wind resources dropped from the 750 million kilowatts to 250 million kilowatts. “A real problem is that wind power resource assessment, if not keep up, we can never know how many of these resources in the end, to develop rational and scientific development plan can not get going.” Investment adviser in the researchers said Jiang Qian.
Obviously, the wind resource planning, online price guide, and network and other key issues not yet clear when the industry’s enthusiasm for wind power at sea was premature.
