18 六 11 Accelerate the development of offshore wind power
China’s major wind turbine manufacturers competing for the year or early next year announced a large-scale wind turbine and actively ready to enter the offshore wind market.
15 to 17 at the “2011 Shanghai International offshore wind power and wind power industrial chain Conference and Exhibition”, United States electric power Co., Ltd. announced that, located in the 6 MW offshore wind turbine will be years off the assembly line . Next year, the company will begin to develop 12-megawatt wind turbines.
Shanghai Electric announced that it will off the assembly line late this year or early next year, direct-drive permanent magnet 5 MW offshore wind turbine.
Goldwind said, its first direct-drive permanent magnet 6-MW offshore wind turbines prototype later this year or early next year off the assembly line, mass production in 2014.
CSIC (Chongqing) Sea Windpower Equipment Co., Ltd. also joined the “beach war”, said in October this year will be 5 MW wind turbine off the assembly line.
In October last year, independent research and development Sinovel 5 MW wind generatos off the assembly line manufacturing. In May this year, its self-developed 6-megawatt wind turbine generator produces official. August, in the East China Sea Bridge, a 5 MW wind turbines for on-site installation. The Sinovel 10 MW and above large fan is also in development.
Also in October last year, Hunan Electric Co., Ltd. introduced the 5 MW wind energy permanent magnet direct-drive offshore wind turbines. The end of June this year, XEMC in the Netherlands and China Fujian offshore demonstration wind farms were built, the second half of this year is expected to achieve power.
Industry experts believe that China’s small wind turbines equipment manufacturing companies to launch such a large fan-intensive, marking China’s offshore wind power has entered the era from 3 MW 5 MW and 6 MW of the transition.
As the world’s fastest-growing new energy, wind power generators has many advantages: more than the development of hydropower potential; than nuclear power construction period is short, safe; than the cost of solar power closer to the traditional energy sources. At present, more than 100 countries began to develop wind power, concentrated in major markets in Europe, Asia and North America.
China Renewable Energy Association Vice-Chairman Shi Pengfei that the special committee, with the high-speed land-based wind power development, the Chinese offshore wind power is still at an early and exploratory stage.
At present, China’s offshore wind power capacity has reached 142,500 kilowatts, accounting for total installed wind power capacity of less than 1%. China stabling of offshore wind power project in Shanghai East Sea Bridge, 100,000 kilowatts project, Jiangsu Dafeng intertidal 300,000 kilowatts last year, the government first round of demonstration projects and 100 thousands of Wahe upwind power tender. And the 2010 World offshore wind power installed capacity 3.5 million kilowatts, the China now accounts for only about 4%.
Nevertheless, China is still regarded as the only outside Europe in 2020 will be the rapid development of offshore wind power market. The next five years, China’s offshore windmill generator will accelerate the development period to enter.

12 六 11 China’s wind turbine manufacturing industry will undergo significant
China’s wind turbine manufacturing industry will undergo significant changes in the wake of new industrial restructuring guidelines which will come into effect on June 1.
China’s wind power industry, which has developed by leaps and bounds over the past five years, will have to follow a new series of guidelines and restrictions, according to the 2011 edition of the Guideline Catalogue for Industrial Restructuring, a set of policy guidelines recently released by the National Development and Reform Commission (NDRC).
The new guidelines state that “new energy” sources, including wind energy, shall be considered as a separate category for “encouraged development”. The 2005 edition of the guidelines stated that wind energy and other sources of clean energy would be grouped in with traditional sources.
Industry officials say that once an investment project is listed in the “encouraged development” category, the company or companies behind the project can enjoy preferential treatments such as floating shares in the stock market, lighter requirements for new bank loans and tax breaks.
However, under the new guidelines, China will not extend these preferential policies to companies that produce wind turbines with 2.5-megawatt-capacity or lower. Instead, the policies will encourage the development of larger-capacity turbines, as well as components for control systems and converters for these larger turbines.
“There is an overabundance of investment in emerging energy sectors, such as the wind power sector. This is the result of an influx of capital into China’s equipment manufacturing industry, which is operating under the idea that China has strictly controlled fixed investments in sectors that consume more energy and resources,” said the NDRC in its interpretation of the new guidelines.
“If we don’t regulate these sectors, companies will encounter problems in production and management. This will hinder independent innovation and restructuring,” the NDRC said.
In March 2010, the Ministry of Industry and Information Technology (MIIT) issued a circular in which it asked for public opinions on the management of the country’s wind power industry. In this document, the MIIT stated that new wind turbine manufacturers must have the ability to produce wind turbines with 2.5 megawatts of power generating capacity or higher.
Industry officials said that with the new guidelines, China has finished fine-tuning its wind turbine manufacturing industry’s policies, and that the production of outdated wind turbines will be eliminated.

07 六 11 The internationalization of China’s wind power how far the road?
The just-concluded U.S. wind energy wind power development companies in China once again stage a show of strength. Including the industry ranked first in China, the world’s second wind turbine R & D, manufacturing Sinovel, a large number of Chinese wind power equipment wind turbines manufacturers and component production showcasing their latest models and products. Being in China, the world’s largest wind power market, based on China’s wind power development, manufacturing and supporting more and more companies began eyeing the international market.
“From a market point of view, the next few years China’s installed windmill power capacity growth will slow, while maintaining the absolute leading position in the Chinese market, while overseas markets for Sinovel is a good choice.” Huarui Tao, senior vice president of wind just told Xinhua in an interview.
According to Chinese Wind Energy Association in March this year, “issued by China’s wind power installed capacity in 2010 Statistics” report, 2010, China added 12,904 units installed wind turbine installed capacity of 18,927.99 MW, up 37.1% year on year; cumulative installed wind turbine 34,485 units, installed capacity of 44,733.29 MW, up 73.3% year on year, continues to rank first in the world.
China’s rapid development of wind power market spawned a large number of wind power equipment manufacturers, also makes the domestic wind power market, competition has become increasingly intense. Ping An Securities Analysis recently released a report has pointed out that domestic wind power machine manufacturing sector has nearly a hundred companies, with domestic growth of wind power installed capacity of wind power machine manufacturer into a “Red Sea” , the increasingly fierce price war has begun to affect corporate profitability. In this market context, opening up new growth market has become the major turbine wind generator manufacturers an important strategy for further development.
Tao Gang, from improved profit margins considerations, such as Sinovel strength of the wind power companies have to enter the overseas market is essential. In recent years, domestic prices fell faster fan, the industry average profit margin is low. In some developed countries abroad, especially wind power market, the fan industry profit margins are generally higher, which sharply with China with a strong research and development of wind power capacity of such enterprises is a very broad market growth.
It is understood that Sinovel construction in India of 10 1.5 MW vertical wind turbines and wind power generation has been successful for over a year; 3 MW series wind turbine by the Germanischer Lloyd (GL ) design certification, product performance, quality, service and other aspects of the local market acceptance; April, after attending the European Wind Energy Exhibition, Sinovel and Greece signed a wind power company PPC generation cooperation agreement in Greece establishment of 300 MW installed capacity of 200 and an offshore wind farm wind farm and wind turbine in Greece to establish production bases, according to estimates, the total co-operation up to 4.5 billion euros.
“In China wind power market competition, size and experience we have accumulated more profound.” Tao Gang told reporters, through years of operation, Sinovel has accumulated a wealth of plant operation and maintenance experience in the low wind speed, high altitude, extreme cold and other extreme conditions of the wind field experience running particularly prominent, these advantages will undoubtedly improve their international competitiveness.
Is not only a machine manufacturer, the wind power industry chain as other Chinese companies to target the international market. Also participated in the development of the American Wind Energy wind turbine blades Sinoma Technology Co., Ltd. Deputy General Manager Wang Xin told reporters, with the machine manufacturers to accelerate the speed of internationalization, leaf production enterprises should also speed up the pace to go out to meet the China’s wind power business as a whole the pace of internationalization.
However, although wind power enterprises in China have “exploiting the boundary” and ambition, but the existing technology, costs and policy bottlenecks still can not be ignored.
Luoyang Bearing Science & Technology Co., Ltd. Deputy General Manager Wang Jinghua told reporters that as a major wind turbine components, the current Los axis has been the production of large bearings can replace the similar products in Europe and America and other countries, and has achieved considerable market share the tradition of breaking the monopoly of European and American companies. However, in the manufacture of precision bearings and small R & D gap between U.S. and European companies are still and seek technological breakthroughs, enhance independent innovation capability of Chinese enterprises is the key to internationalization.
Tao Gang, as current domestic machine manufacturers a home wind turbines comprehensive industrial base mainly in the country, taking into account the problem of transportation costs, companies need to be more international industrial layout. In addition, how the layout of enterprises in the domestic production capacity advantage of the strengths and services abroad and adapt to the challenges of the policy environment, also is China’s wind power companies to go out on the road need to make efforts to solve the problem.

05 六 11 Wind turbines manufacturers are feeling the industry
Wind turbine manufacturers are feeling the industry performance pinch for the first time after five years of good times in China, the world’s fastest-growing wind power market, said industry experts.
Following recent incidents where a total of 1,346 wind turbines generator were disconnected from the power grid on April 17 in Gansu and Hebei provinces, China is planning to issue stringent national standards for wind turbine manufacturers.
The incidents, which caused energy wastage, reduced electricity output to millions of customers.
The national standards, being drawn up by the government, are expected to set the tone in the industry, requiring that all installed wind turbines are equipped with low-voltage ride-through (LVRT) capability to ensure stability to the power grid.
LVRT refers to the capability of small wind turbines to maintain continuous operation during and after precipitous voltage dips, allowing the power grid to be adjusted more quickly and improve the overall safety and stability of the grid.
“This will put considerable pressure on wind turbine makers and wind farm operators to upgrade China’s 34,000 wind turbines,” said Li Yinghua, deputy director of the security regulatory bureau under the State Electricity Regulatory Commission (SERC).
Compulsory national standards for wind-generated electricity are needed to regulate grid compliance and build a strong smart grid in the country, industry experts said.
At present, most of China’s installed wind generatos do not have the LVRT capability and domestic manufacturers are upgrading their machines in the wake of the recent incidents in Gansu and Hebei provinces.
The State Grid, China’s largest power distributor, issued the current standards in practice for wind power operators in 2009, but these were not enforced nationally.
It costs between 10,000 and 500,000 yuan to upgrade a single wind turbine by installing LVRT, depending on the turbine model, said experts from Denmark-based Vestas Wind Systems, a leading international wind turbine manufacturer.
“Some turbine models merely need software upgrading, while others require much more than that,” said Shi Haifeng, an expert with the Finland-based The Switch, a leading supplier of wind turbine components.
Wind turbine manufacturers are capable of installing the LVRT technology but some wind farm operators do not want the function partly due to cost concerns, an expert from a European wind turbine manufacturer said.
“LVRT capability is not the only reason for the system’s failure,” said Qin Haiyan, secretary-general of the China Wind Energy Association. “Even with the technology, such disruptions are still inevitable because the power grid is a system.”
Meanwhile, the current standards also suggest wind farm operators to install the Static Var Compensator, which costs at least hundreds of thousands yuan and can maintain steady voltage and stabilize the windmill power system.
According to the European company expert who declined to be named due to company policy, the wind farms in Gansu and Hebei, where the disconnection took place, did not have the Static Var Compensator, which could help to regulate voltage and regulate the power system.
China increased its total wind power capacity to 41.8 gigawatts in 2010, up 62 percent from the previous year.

21 五 11 Wind power reactive voltage control of the development
Wind power as the world development and utilization of renewable energy in the most mature, most technical scale development and commercialization development prospect one way of generating, because its in reducing environmental pollution, adjust the energy structure and solve problems such as remote area residents of electricity is more and more prominent role world attention and received extensive development and utilization.
According to China’s wind power development planning, our country will be in gansu, Inner Mongolia, xinjiang, hebei, jilin and jiangsu establish seven million kilowatt wind power base, is expected to be completed in 2015 to 5808 million kilowatts, built by 2020 9017 million kilowatts, accounts for the total capacity of wind power installed 78%. Because our country onshore wind resource focus mainly on “three norths” area, so in the end of the grid for windmill power base, besides having the common problems in conventional wind power outside, still exists many special personality problems, including the system stability, transmission capacity, FM load and power XiaoNa etc, with reactive voltage problem is wind parallel operation concern, one of the main problems on wind farm to take measures to effectively regulate the reactive voltage.
Development present situation
Early wind generator mainly adopts induction generator, they don’t have to maintain and adjust voltage level of ability, machine at run time but also from the system absorbs reactive power, accordingly, wind power needs compensate, with installed fixed power electronic technology development, the emerging SVC and dynamic reactive STATCOM, etc, wind farm will take fixed capacitors + dynamic of reactive compensation devices to control of reactive way.
In recent years, with the wind generator .at the voltage stability and reactive power compensation issue has is the electric power enterprise and related research institutions concerned hot spot. In this context, the domestic gradually launched on wind farm reactive control technology research, including the wind generator reactive power control technology research, wind farm reactive compensation device research, FACTS device coordination control, etc.
(1) the wind generator reactive power control technology research situation
The wind technology development, from the original not wind generator with reactive control ability development to can output certain reactive. At present, doubly-fed type asynchronous wind generator and permanent magnet straight flooding WTG is the mainstream models, doubly-fed type asynchronous WTG through control implement the meritorious/reactive power decoupling, have certain dynamic adjusting reactive power output capacity; And permanent magnet straight flooding because of wind turbine generators with grid connections throughout the capacity can be flexibly to reactive to control them. These two kinds of wind power generation units with constant voltage mode has ability to work in a certain extent, can realize the control of reactive power and voltage.
(2) wind farm research status of reactive power compensation device
In order to adapt to the needs of different occasions for wind farm, reactive power compensation device has been developed a variety of types, their endless and same, the cost of the network voltage transient characteristics influence is not the same.
(1) parallel capacitor
The shunt capacitance compensation usable breaker power system connected to a certain nodes, parallel capacitor can only to the system of supply capacitive reactive power. The shunt capacitance provinces, with investment, simple structure, operation economic maintenance convenience, capacity can be arbitrary choice, practical strong; Defect is: (1) parallel capacitor compensation is through capacitors because cast cut realize JieTiXing adjustment is not flowing adjustment in system operation process cannot achieve optimal compensating state. Vote by capacitor grouping, cut way by reactive power compensation effect of capacitors grouping number and the capacity of each group capacitor restriction. (2) capacitors mainly by vacuum circuit breaker cast cut, its pitch cut realization, unfavorable slow reaction frequent operation, so it cannot be reactive load on the fast track compensation. If using thyristor shots of capacitors instead of cutting with vacuum switch shots of capacitors, solve the cut cut response slow and switch shots when off big problems current impulse, but cannot solve the reactive adjustment is not smooth and the contradiction of capacitors grouping, at the same time because adopted high-power electric power electronics device, also greatly improved the system cost. (3) due to switch shots capacitor is grading compensation, cut inevitable appeared compensation and owe compensating state. According to the reactive power and voltage relationship will cause voltage, compensation increases, owe compensation caused when the voltage reduced. Perceptual load (4) voltage drops sharply, to the detriment of voltage home wind turbines stability, investment produces rush voltage pulse. Capacitor issued reactive power and voltage is proportional to the low voltage, when the reactive power reduce output, then clearly needs more reactive, if not timely supply reactive, will cause the system voltage level of decline.
