Mechanical Seals Manufacturer In China » wind generators http://www.hfanlx.cn Professional Mechanical Seals,Rubber Mechanical Seals、Carbone Sealts In China Mon, 06 Feb 2012 15:35:35 +0000 http://wordpress.org/?v=2.8.2 en hourly 1 Two other Chinese wind generators makers http://www.hfanlx.cn/archives/658 http://www.hfanlx.cn/archives/658#comments Wed, 25 Jan 2012 14:03:18 +0000 admin http://www.hfanlx.cn/?p=658 “We are hiring lawyers to challenge the allegations,” said Wang, whose company is a unit of China State Shipbuilding Corp.
Two other Chinese wind generators makers, Titan Wind Energy (Suzhou) Co and Shanghai Taisheng Wind Power Equipment Co Ltd, also expressed concern, saying any anti-dumping duties by the US could hurt their prospects in a growing market.
However, according to industry insiders, the majority of China’s windmill power companies will not be affected by the investigation.
“First, the production of wind-towers doesn’t contain too much technology,” said Shi Pengfei, vice-president of the Chinese Wind Energy Association. “Second, the export market is still on a small scale for Chinese manufacturers.”
He said the Chinese companies can tap the growing domestic market even if the US stops imports of Chinese wind towers.
The towers are most often exported to the US because of lower production costs in China. On average, the cost of a wind tower accounts for 20 percent of a wind turbine, which cost $600,000 each. The price often depends on fluctuations in the cost of steel, which is the main production material.
Wind-tower manufacture doesn’t require a large amount of technology, so Chinese companies have cost advantages because of the lower labor costs in China home wind generator, said Li Shengmao, a senior industrial researcher at the CIC Industry Research Center.
He added that, in addition to the companies listed the investigation, others manufacturers should also be prepared for possible probes.

Help to develop new intelligent wind generators, energy system supplier Alstom (Alstom) and energy technology research and development institutions Ikerlan – IK4, are using IBM software development WTG control system, which can greatly improve the sustainable energy based on wind power system performance.

Using new wind turbines advanced electronic sensor system and IBM software, can make based on relevant wind direction and wind speed, temperature factors such as the input performance to optimization. Central control system to collect and analyze the data from each turbines, remote control individual generator subsystems, carries on the diagnosis and management of wind power generation. Alston and Ikerlan – IK4 are using IBM software to help develop and make “system of” automated, to control the turbines and Internet communications system.

Alston and Ikerlan – IK4 estimated that they use the IBM and Big it software can reduce up to 25% development costs, and may reduce the coefficient of variation of each product development time. Through the use of IBM for Rational software development model driven Gears, plus BigLever applied to product engineering, can reuse software asset management, and these changes, to keep pace with the demand of the market.

It is reported that power station is located 12 km away from the UK North Sea side, the British Government vigorously promoting the “renewable energy plan,” the important part.
Power spokesman said the body huge wind turbines can produce 500 million kilowatts per year of electricity. The data show that the base of each wind power up to 115 meters, an area equivalent to the entire 4000 football powerhouse. The wind power generators plant is expected to run at least 25 years. However, the only disadvantage is that wind power may be affected by the natural environment is relatively large, so occasionally interrupted power supply.
