Construction Of G58-850KW Wind Power And Analysis Of The Power Output Rate

Under the dual pressure of lack of normal energy and deterioration of global ecologic environment, wind power becomes a substitute for it's a kind of pollute-free, renewable and clean energy. During past 30 years, wind power has been seen a very quick development. The competition ability of wind power both in economical and technologic aspects has been enhanced greatly due to the fact that the developed countries excised a tax on some energies in purpose of preventing the effect of global warming, acid rain and reducing green house effect and dioxide, nitrogen emission.China is a country with rich wind resources for it locates in the South-east of Asia and neighbors west of the Pacific Ocean. Seasonal wind is powerful. Especially the North-east, North-west as well as coastal areas have large wind resources. In recent years, wind power technology has experienced remarkable development, the wind turbine design and manufacturing technologies steps into maturity. As a result, MW wind turbine is on the way to development. Therefore, the cost competition of wind power becomes stronger. To China, a developing country, it is of great technological, economical and strategic importance to set up a long term plan of developing renewable energy and pushing the wind power technology and industry to be globalized.Thanks to Ningxia geological location, sitting in the North-west part of China, it has obvious season distinction and the weather condition is at the edge of riptide of Northern Branch of Tibet Tableland, consequently, the wind resources reservation in Ningxia is among the toppest in China. This thesis gives a brief introduction to basic theory of wind power, construction of wind farm and commissioning and operation of wind turbine by illustrating the 3rd Phase Extension Project of Ningxia Electric Power Group Co.,Ltd Helanshan Wind Fram.Based on the specific study on the engineering construction and the domestically and globally popular 850KW WTG, further by comparasion of the power output rate of G52 and G58, we can prove that with substitute of new material and new technology, larger capacity WTG will become popular. Especially when the running diameter of blades enlarged, more power produced at same wind speed; and the high efficiency will be further guaranteed if the gearbox, major shafting equipment be checked and maintained regularly.
