Wind power generation are a major form of wind energy utilization, the Chinese wind power generation has been carried out for many years, as China’s energy and environmental change and wind power industry matures, Chinese wind power generation over the next few years will show a new trend.

1, wind power costs will be substantially reduced

Compared to wind generators power solar power, biomass and other renewable energy technologies more sophisticated, lower cost, less environmental damage. In the past 20 years, wind power technology continues to make breakthroughs and economies of scale and become increasingly evident.

According to the United States National Renewable Energy Laboratory NREL’s statistics, from 1980 to 2005 period, the cost of wind power declined by more than 90 percent, a decrease faster than in several other forms of renewable energy. RIS according to the Danish National Research Laboratory on the installation at the Danish wind turbine assessment, from 1981 to 2002, wind power generation costs from 15.8 euro cents / kWh down to 4.04 euro cents / kWh, the annual electricity cost by 2010 is expected to drop to 3 euro cents / kWh, 2020 was reduced to 2.34 euro cents / kWh.

With the improvements in wind  generators or wind turbine technology, wind turbine will be more cheaper and efficient. Increase of stand-alone wind turbine capacity reduces the cost of infrastructure investment, and the same installed capacity of generating units need to be more a small number of purpose, which also cost savings. With lower financing costs and developers have experience in project development cost is reduced accordingly. Wind turbine reliability improvements have reduced the average cost of operation and maintenance.

Overall, the cost of wind power will be greatly reduced.

2, technical equipment is bound to increase the proportion of domestic production

Implementation of wind power technology and equipment made aimed at improving China’s wind power equipment manufacturing capacity and technological level of wind power to reduce costs, improve market competitiveness, in order to promote China’s wind power generation technology of large-scale commercial development to lay the foundation. Increase the wind turbine in China, and on the one hand, the construction of wind farms for the use of domestic equipment to provide quality low-cost selection; On the other hand, can also be forced to participate in similar foreign enterprises in China’s competition in the market substantially lower product prices. Wind power technology and equipment made the guiding idea is based on market-oriented and engineering-based digestion and absorption in the introduction of international advanced technology based on innovative improve, the development of independent intellectual property rights of wind power generation equipment.

Implementation of domestic wind turbine of 70% and is expected to reduce the wind turbine component of this 15%, without changing other conditions, will enable wind power generation cost to 0.375 yuan / kWh. Such as the full implementation of domestic wind turbine and wind turbine is expected to reduce the composition of the present 30%, without changing other conditions, will enable wind power generation cost to 0.332 yuan / kWh. To this end, the country must increase investment in scientific research and development, in the current conditions in order to wind farm construction investment ratio of 1.5-3% of the Supporting China’s wind power technology research and development and domestic production are appropriate. Their significance lies not only in reducing the cost of wind power, will also promote China’s wind turbine industry in the formation, using our strengths to the international market.

3, quietly rising sea wind power will become important forms of energy

The sea has rich wind power resources and a broad flat region, making offshore wind power generation technology has recently become a hot research and application. Multi-megawatt class wind turbine offshore wind farm at the commercial operation of wind energy at home and abroad are using the new trend.

The international level, to the end of 2003, around the European coastline, the total installed capacity of offshore wind power generation 600MW, concentrated in Denmark, Sweden, the Netherlands and the United Kingdom. At present, the largest offshore wind farms are located in coast Nysted wind farm capacity of 165.6MW, from 72 Units Bonus2.3MW sea wind turbine components, in December 2003 began to generate electricity. Estimated that by 2010, the European offshore wind power generation capacity will reach 10000MW. Large and stable wind speed at sea, using the number of hours to reach more than 3000 hours. The same capacity installed, sea than on land costs increased by 60%, electricity consumption increased more than 50%. With the development of wind power generation, land on the total number of fans have already become saturated, the sea wind farms will become the focus of future development. Sea power in recent years the international wind power industry development of new fields, are “the direction of direction.”

Chinese wind energy at sea than land-based wind energy resource reserves, reserves of 10m high wind energy resources available to more than 700 million kW, and the distance very close to load centers. Currently, Shanghai has begun to offshore wind power generation projects that by 2010, Shanghai’s total installed capacity of wind power will reach 200-300 MW. To achieve this goal, China’s first long-distance cross-sea bridge to be built on both sides of the East China Sea Bridge, the first Chinese mainland wind farms at sea.

With the sea wind farm development of sophisticated technology, economically viable, the future will inevitably become an important sustainable energy.

4, wind generators continue to develop large-scale

With the development of modern wind power technology matures, wind turbine is constantly to the large-scale development. Before and after 2002, the international wind power market model has reached the mainstream more than 1500 kilowatts. At present, the bulk of Europe has been the installation of 3600 kilowatts wind turbine, the United States has successfully developed wind turbine 7000 kilowatts, while the UK is developing a giant wind turbine. At present, wind turbine size has been increased, the international mainstream on the wind turbine has reached the 2-3MW. MW-class fans in 2004 has become the mainstream of commercial units, 1.0MW fan above MW of installed capacity accounted for additional 74.9 percent, a slight increase over 2003, twice in 2000 are.

Generally large-scale wind turbine has two development models. Land-based wind power, its direction is low wind speed power generation technology, the main models are large 2-5 MW wind turbine, this model is the key to the transmission grid. Offshore wind power, mainly used for relatively shallow coastal waters, the installation of more than 5MW of large-scale wind generators, layout of large-scale wind farms, this model are the major constraints on wind farm planning and construction costs, but the offshore wind power advantage is obvious, that is not occupied land, offshore wind resources better
