Five risks facing the offshore wind power generator
wind generators

2010, offshore wind power generator as a prelude to the start of the concession tender officially launched. Although offshore wind power has a good wind resources, coastal network architecture is superior, the advantages of close to load centers, but its risks can not be ignored. Compared to wind farm developers, equipment manufacturers and other interested parties, the more directly bear these risks. China Guangdong Nuclear Wind Power Assistant General Manager Lu Hao said: “The offshore wind power development with high-risk, and advanced features.”

Long processing time and high cost

China’s offshore wind generators resources such as wind from the Shuiguizongyuan responsible for approving the survey, it was understood that Shuiguizongyuan very strict examination and approval. Marine environmental assessment and preparation of the report and assessment route longer time. General approval from the wind to the sea project a reasonable time was 2.5 years, longer than the land-based projects. In addition, the sea-front costs of developing wind power is wind power on land about 10 times.

Fan high price, design experience less

Although the major wind turbine manufacturers competing maritime R & D fans, but the real volume manufacturers can rarely, short-term memory in the case for less than the demand, developers keep the prices down in the little room. In fan technology, domestic manufacturers to take part of the system fan pickled I design principles to improve the offshore wind turbine reliability and availability, but may increase the device cost. Add twice the equipment cost is still in a high level.

In the design of wind farms, there are certain offshore wind turbines design institute of design experience little, competition is not sufficient to design the high cost. Design costs as the proportion of small, risk is relatively small, design experience are a major risk.

Multiple risks faced by construction

Wind from the currently available data, China’s annual 50-meter-high coastal wind speeds ≥ 8m / s wind speed of the time is 40%, ≥ 10m / s wind speed accounted for 20% of the time, showing that construction of wind on the sea have a certain impact.

It is understood that whole sea area north of the Yangtze Estuary can work for about 1/3-1/2. Generated in the Western Pacific, 29 tropical cyclones each year, of which can affect tropical cyclones north of the Yangtze Estuary annual average of 3.1, up to up to 7 years (1990), at least 1 year only. 1949-2007 years, a positive landing north of the Yangtze Estuary were 5 times (2%). Waters north of the Yangtze Estuary can be seen every year by the impact caused by the typhoon, but are less opportunities for attacks.

As the domestic manufacturers and construction unit fans lack experience in building offshore wind, the early construction, construction progress will be slower, but with the progress of the project, with the maturity of various types of work, progress will accelerate gradually. But in general there is the potential risk of contractor delays.

Evidently, not yet specialized for lifting vessels at sea fans. Construction of multi-base can be installed more domestic vessels, but can be more than 5 meters in diameter pile foundation construction of the vessel less. East China Sea Bridge, a similar scheme can, with the overall lifting capacity floating crane lifting all boats, 20 domestic, but most of lifting height is not enough. Shows that if large-scale offshore wind power development, the lack of construction of the ship’s problem is quite serious.

Wind farm operation and maintenance risks

Ease of maintenance points to reach the main by the weather, sea conditions, distance and transportation decisions. Distance offshore wind farm, the general 10-50 km offshore. In addition to fans of quality, high reliability requirements other than necessary maintenance is indispensable. Currently abroad, offshore wind generators farm maintenance overhaul the means of transport are boats and helicopters. The two modes of weather, sea conditions, a significant influence.

Availability from the fans point of view, the fans in terms of land, offshore wind turbines require higher reliability, learned from the current situation, offshore wind turbine availability is generally low.

Submarine cable is the problem can not be ignored, it is known, the domestic 35KV and 110KV submarine cable technology is more mature and complex. But can not produce 220KV submarine cable. The cost of submarine cables is 5-10 times the land, while there is the risk of anchor damage. Relatively strong coastal grid structure, but involves offshore wind farm in the local network is also weak, according to a potential reason as rife electric grid can not run the risk of full power.

Offshore wind turbine tower tube for years by the invasion of sea salt, the corrosion rate faster than the terrestrial environment, in addition to the tower tube manufacture in strict accordance with the requirements of anti-corrosion coating, regularly checked to maintain the tower tube. As the fan base is located in the seabed, seabed local shape changes in the waves, tides and currents of the role of seafloor topography in sports, on the basis of the stability of great impact, sometimes endangering the safety fan. Although fully into account in the design of ocean currents, waves, tidal effects on the basis, but fans running, the fan base should be regularly diving observations and maintenance.

Internet Risk

Countries have not developed a unified price of offshore wind power the Internet, and Internet access Dianjiaqueshi yes developers access to sources of revenue for Zhu Yao, Ming Que Tariff Ke Yi Shikaifashang Heli De Tou financing plan developed.

In addition, the coastal areas although the higher level of network structure, but involves the Internet for offshore wind power shortage still exists, grid companies involved in offshore wind power development in the responsibility should be strengthened.

NDRC Energy Research Institute, Junfeng, deputy director, said: “the development of offshore wind speed although fast, but there are many questions, our offshore wind power is not enough scientific research and technological development, technical reserves, lack of practical project operation experience, in practice they need to be addressed seriously. “

As of the end of 2009 China’s wind power generators installed capacity of 25.8 million kilowatts, accounting for about 1% of total power generation, photovoltaic power generation capacity of 750 million kilowatts. Concerned that the U.S. renewable energy accounts for the proportion of total power production was lower, demonstrating both large-scale renewable energy power generation and network technology R & D has a broad space for cooperation.
In response, State Institute of net energy gap in the forum Bai Jianhua, Deputy Chief Economist accept the “China Energy Report” interview, said that the current large-scale wind generators development in China need to optimize the power structure, increase the peaking intensity.
At the same time, through system optimization analysis, by 2020 the country’s cooperation in the development of wind power is about 102 million kilowatts scale. If the time to reach 150 million kilowatts of wind power installed capacity of the scale of need in-depth study on the optimal development plan. Bai Jianhua said, which provided for the two sides for cooperation.
Bai Jianhua that the United States in wind generators and network problems on a large scale areas of cooperation should include: a large-scale wind power grid and Absorptive planning methods and network technical standards, clean energy power ancillary services pricing and compensation Machine policy mechanisms and the only network-related technology research. “We have to study and network problems before have fully drawn on the experiences of Europe and the United States and other countries, Sino-US cooperation will further promote the introduction of foreign advanced technology.” He said.
26, the opening ceremony, the two sides signed, including aviation biofuels, natural gas, distributed energy, smart meters, the field of cellulosic ethanol, the five eight cooperation agreements between the government and enterprises. A day earlier, the second round of China-US Strategic and Economic Dialogue in Beijing. During the meeting, the collective results obtained 26, the two sides that “agreed May 26 to 27 at the first ‘American Renewable Energy Forum’, ‘Sino-US Forum of advanced biofuels,’”, thus, the formal convening of the Forum come into being.
Zhang pointed out that the recent years, with renewable energy policies and regulations and improve the market mechanism, work together to promote the rapid development of industry. Some domestic areas of wind power and photovoltaic manufacturing companies have listed overseas, the global wind power and photovoltaic manufacturing, “giant” also have to enter the Chinese renewable energy market, the favorable situation, the full benefit from the introduction and absorption of foreign advanced technology and investment policies , where renewable energy has become the most important career development experience, and will continue to carry out.
National Energy Board Chief Engineer Wu china wind turbines stressed at the forum also said that Sino-US energy environment and are faced with the challenge of climate change, developing renewable energy sources is a common choice between the two countries, bilateral energy cooperation is the greatest consensus.

2009 U.S. offshore wind power generation potential of Analysis
wind generators

Although the cut-off by the end of 2008, the U.S. wind power generator installed capacity reached 25.17 million kilowatts, has overtaken Germany’s 23.9 million kilowatts, ranking first in the world. But the vast majority of U.S. wind turbines development mainly in areas of onshore wind, offshore wind power development is slow. Investment Advisor in the latest release of “2009-2012 China’s wind power equipment industry, the prospects for investment analysis and forecast report” shows that the current global development of offshore wind farms mainly in Denmark, the Netherlands, the United Kingdom, Sweden, Ireland, Germany and other countries. In this regard with the EU countries can be developed in a relatively small land-based wind generators resources on the other hand, offshore wind power development due to a higher technical difficulty, only those already in the field of wind power development has accumulated sufficient experience in the EU countries have the ability to development of offshore wind power project, while the emerging countries of the offshore wind power generator installed capacity in the gaps in the basic state. Jiang Qian believed that the reason why offshore wind power is not yet in the global promotion of large-scale, mainly because there is no breakthrough in its technical bottlenecks. However, offshore wind farm are generally close to the power load center, coupled with the advantages necessary to grab the land area, the prospects for offshore wind power at sea is relatively bright. The U.S. up to 900GW of offshore wind turbine potential, if fully exploited, it should be on the entire global wind power industry a huge boost.
The world’s first commercial tidal wind generator input
wind generators

While the clean and green renewable wind energy sources, but a high degree of dependence on the weather, thereby limiting its development. The use of ocean tides to generate electricity dependence on the weather, we should much smaller power, tidal power has therefore become the field of renewable energy sources in recent years, a hot new term. Recently, in the UK the world’s first tidal energy generators put into commercial operation.

This was named “SeaGen” tidal generator is located in Northern Ireland, Strangford Bay estuary, which is about 37 meters, 47 meters high, with a total weight of more than 300 tons. The principle is the use of tidal power tidal fluctuation of water level difference to wind generate electricity, the generator is equipped with two tidal energy turbines, is like an “underwater windmill“, its principles and wind power generation is also similar, except the wind push changed to promote the tides and currents, resulting in more environmentally friendly power. The system since May 2008 began trial operation, the current generating capacity of up to 12 megawatts, about 1,000 households to meet the average electricity demand, the highest in the world’s first tidal energy system capacity. However, tidal power because it is a new technology, its cost of wind power generation is also high, about the cost of other new energy generating four to five times, but with improved technology and extension, which is expected to reduce the cost of the future. Tidal power generation is also being subjected to wave the size of the wind turbines impact and possible impact on marine life concerns, although “Se aGen” generating units have been commercially available, but its follow-up there are still many problems waiting to be resolved.
