Regular maintenance can make devices to keep the best of the state, and to extend fan life. Regular repair and maintenance work of the main elements are: fan couplings between the bolt torque inspection (including electrical connections), the lubrication between the transmission components and various functional tests.

Fan in normal operation, each connected component of the Bolt to run in a variety of vibration of long-term effort which is very easy to loose, so in order not to loose bolts after the cause of local Shouli Bu were cut, we must regularly Bolt torque check of their conduct. In the environmental temperature is lower than -5 ℃, should make it down to the rated torque for tightening torque of 80, and after the temperature is higher than -5 ℃ review. We generally check on the fastening bolts are arranged in non-small air or wind in summer, to avoid the high power fan season.

Fans of the lubrication system mainly dilute oil lubrication (or lubrication of mineral oil) and dry oil lubricating wind turbines (or grease lubrication) in two ways. Fan gear boxes and yaw Gear Box uses a thin lubricating methods, the maintenance is of additional testing and sampling, if the test results show that the lubricant can no longer use, then wind power generator replaced. Generator parts are dry lubricated bearings, yaw bearing, yaw gear and so on. These components run as high temperature, highly degenerate, resulting in bearing wear and tear, regular maintenance must be carried out each time up to its increase. In addition, the generator bearings according to additional doses of a certain number of requests to join, not too much, to prevent too many to squeeze into the motor windings after, the motor burned out.

Regular maintenance of functional testing test key too quickly, emergency shutdown test, hydraulic system component value test, vibration test switch, twisted cable switch test. You can also set limits on the controller, some routine test values. In addition to regular maintenance other than the above three items, but also check the hydraulic oil level, small wind turbines the sensor for damage, the sensor’s power supply is reliable work, brake pads and brake disc wear and so on.
China’s wind power industry is facing three bottlenecks
wind power

First, the wind power issue is the development of China’s wind power industry prominent bottleneck. According to the China Electricity Council statistics, in 2009 China’s total wind power installed capacity reached 22 million kilowatts, and the network unit is only 16.13 million kilowatts, and the network unit is not more than 1 / 4. Meanwhile, the wind load characteristics determine its difficult to maintain stable and can not synchronize with the power load changes, there must be other wind power commitment to adapt to changes in load demands, to increase power generation capacity adjustment, peak shaving capability and storage capacity. This requires optimization of the power structure, increasing investment and operation of pumped storage units, increase the peaking power construction scale.

In order to strengthen the research and wind forecast, China’s current wind observation tower built about 400 of them. However, this is not enough, but to build wind power generator forecasts and forecast system, need to promote wind power and grid companies to achieve coordination and cooperation. China Electrotechnical Society, honorary chairman of Zhouhe Liang told the reporter, to achieve this step, the national electricity access to assessment, not only the evaluation capacity. Because the installed easy, and the net hard. Once the online assessment targets to achieve power, the state of all aspects of the unit to reward, motivate, including wind farms, power companies, especially power companies. As wind power, mainly rely on power companies to promote.

Wind energy resource-rich areas are mostly small wind turbines local power system, electricity load less, the news on the assimilative capacity of wind power inadequate. To solve this problem, the key is to increase the intensity of cross-network construction.

Zhou Heliang that the development of wind power to the grid and network synchronization with both non-development, the formation of diversified, balanced development pattern. In the wind energy resource-rich areas, construction of wind power base, building a large network, but also small and medium sized wind farm construction according to local conditions, to meet the remote and inaccessible areas of the electricity demand.

Second, the wind power industry, machine wind generators manufacturers still excess capacity, lack of equipment reliability issues. At present, many domestic fans machine manufacturers, hundreds of family traditions, national electric machine has been assembled, manufacturing companies. The market share of 60% of the total concentrated in the gold wind, sharp and East China Steam hands. The three have an annual output of domestic enterprises with more than 2 million kW, and the remaining 40% of the market share of family property to lower the machine nearly a hundred works by intense competition. To prevent redundant construction, the Ministry of Industry in March 2010 issued a wind power equipment manufacturers access to draft standards to improve the access threshold for wind power equipment, reduce excess capacity. Meanwhile, National Grid is also studying the development of relevant technical standards and network specifications.

In this regard, Zhou Heliang that reduce excess capacity should aim at capacity, but also to improve equipment quality, performance, level of direction.

In recent years, Zai policy strongly, supported by technical Yin Jin, China mastered the group Zhizao MW wind turbine technology, and initially formed blades, gearboxes, generators and control systems Zhuyaobujian the wind Dian equipment Chanye chains, You Yu Da Duoshu windmill power businesses once Zhi Zao, light innovation, Chong Yin Jin, light Xishou, Shi wind power for critical equipment and core Jishu subject Guowai, wind power technology independent innovation capability as weaknesses, in particular, key components of quality of equipment Urgent Improvement of Quality . Coupled with the rapid development of China’s wind power industry, launched a large number of fans rushed the equipment from the research and development to the actual running time is shortened, so that lack of preparation as a result of R & D fan is running a series of problems emerged.

Zhou Heliang that equipment reliability issues will affect the development of wind power in China a huge worry. China’s wind power equipment manufacturers need to focus on wind power main and auxiliary machine optimization and matching, to improve equipment reliability should make great effort.

In the rapid growth of wind power against the background of a few years, most enterprises focus Yu make and the wind power industry R & D platform and public technical service system is far from the pace of development of the industry does not , efficient production, learning and research combined technology R & D system still in a primitive being.

The third is the wind farm’s operation and management level is too low. A lot of attention to installed capacity of wind power projects, while ignoring the run. A lot of wind, whether maintenance, repair capability, or maintenance, management capabilities are to be improved.

Wind turbine generator contract prices show the price in 2010 compared with 2008, in the second half of 2010 and 2011 delivered the first half of wind turbine prices will continue to be significantly reduced. According to Bloomberg New Energy Finance (BNEF) recently published the third phase of wind turbines price index (WTPI) shows that this decline by as much as 15%.

BNEF analysis shows that in 2008 signed the delivery of the first half of 2009 the price peaked turbine generator sets, the price reached 1.22 million euros / MW. However, due to the financing of wind power projects, the current oversupply of global wind power market, making 2010 the second half of 2010, signed in the first half of 2011, the delivery of wind power contract prices have fallen, the average price of 1.04 million euros / MW.

In addition, the recent being negotiated in the second half of 2011, reported out a contract to deliver the same price, there is no signal that the recent price rebound fan signs. Here’s the price including freight, but does not include VAT and all other construction costs.

The main wind turbine generator buyers expect in 2010 and 2011, prices will fall further, decreases were 4% and 1%, while the expected price rise will occur in 2013.

BNEF the wind observation services manager William Young said, “wind generators never expected the price so low, but the current excess supply situation will continue for a long time. Of course, this is not the wind turbine manufacturers are willing to look at to, but the industry is concerned, this will increase wind power and natural gas, coal and nuclear power more competitive.
TV policy to promote the development needs of the wind turbines

Difficulties under the wind power industry will be how to achieve great development?

“Wind power industry based training to support the development of poor areas is a long-term goal, can be used as an obligation to implement, it requires effective legislation and policies to support industry. After re-address the issue of energy and environmental protection.” Long Yuan Electric Power Group Long Yuan Electric Power Group senior engineers YANG Xiao-sheng think.

In addition, due to the weak industrial base of wind turbines equipment, such as multinational brands in the technology to step up control on the Chinese side at the same time, research and development, procurement, facilities, manufacturing, marketing and other aspects have also strengthened the control of the industrial chain. “Of course, the domestic wind power companies, this is both a promotion, is also a challenge.” Association of Chinese Renewable Energy Professional Committee of Experts HE De Wind said.

Hunan Electric Group Chairman Jianxiong believe that this challenge is pioneering. He said that the time goes forward, non-renewable energy will become more intense; on wind generators, the power generation capacity is, the higher technology content, the lower the cost of wind power. The two eventually reach a balance point, wind power costs will be very close to or lower than current conventional power, wind power in energy supply and the role of reducing greenhouse gas emissions will become increasingly significant
