Homemade Wind Generator

History Wind Use in the United States has a long history, about a few centuries ago, Americans used the windmill and other devices to nature in the wind into mechanical energy for grinding grain and carrying water. 1888, CharlesF.Brush invention 12kW DC wind generator, a wind energy technology in the development of a milestone, marking a wind energy conversion from mechanical energy into electrical energy conversion application of the era. Brush invented impeller diameter 17m, formed by the 144 wood blades. After 50 years, off-grid small-scale independent power generation system has been the mainstream of the American Wind Energy Technology. 30 years until the 20th century, the first exchange of fans installed in the United States to run. However, large-scale grid-electricity technology and the rapid development of low-cost fossil fuels, so the cost of grid electricity decreased rapidly become a major source of energy. Fossil fuel monopoly in the electricity market, wind power can not become a mainstream technology for power generation, an option to slow development. Into the 70's, energy supply security and the depletion of fossil energy crisis as the U.S. economic growth and social stability of the enormous challenges faced to develop alternative energy sources as fossil energy in many countries including the United States an important part of energy strategy, in which background Wind power is widely under the attention and importance as an advanced technology energy reserves in the 80's after the phase of rapid development.

20 Century 80 wind turbines began to rise early, and today after 20 years of technology innovation and commercialization of wind power generation has become an important large-scale and grid technology. Denmark, Germany, the Netherlands, Spain and the United States is the development of wind power generator and the power to master the most advanced wind turbine technology and control technology. 70 years of the 20th century, wind power diameter of only 10m, generating capacity between the 22 ~ 35kW; Today's wind turbine diameter 80m, generating capacity to a few megawatts. Stand-alone capacity of the continuous improvement of wind turbine technology for business promotion. 20 years of wind turbine technology has undergone many changes, variable angle blade instead of a fixed angle blade, direct drive instead of a locomotive driver, instead of constant speed conversion system conversion system. In addition, wind power system control technology continues to mature and produce materials to optimize performance. The main wind power technology development trend, it is necessary to develop for large-scale offshore wind farm wind power Generator Full use of offshore wind energy resources; followed by expanding the market for small wind generator systems development, including export to developing rural areas. In recent years in the U.S., small network unit (10kW) applications are very common.

Over the past few decades, we have seen a great deal of inventions introduced to society that are aimed towards bettering our lives. These inventions utilize new and innovative ideas and designs to harness energy. Inventions that evolve around the use of wind have been in circulation for a number of years, but it has only been recent developments resulting from our curiosity about alternative energy sources and our drive to make energy more efficient that we have come to notice the true potential of wind as a true energy source.

The construction of large-scale wind farms has enabled us to take full advantage of the use of wind and turn this into an effective and useful energy source. The use of large wind turbines allows us to convert the power of wind into electricity. There are three different types of wind farms; those that are off shore, near shore and land based wind farms.

HC HVAC & R Network  Following the Cape wind farm after the mountain top, at the southern tip of Cangnan County, Zhejiang, last month added an installed capacity of 1.4 million kilowatts Kasumigaseki wind farm, expected annual energy output of more than 10,000 households for urban households to use.

Cangnan County Office of Development and Reform Bureau Deputy Director Early, senior engineer Lu into a standard that the emperor was also the county level is building wind farms, another five wind farms have been carried out early wind, seven have signed preliminary wind agreement. He said that according to expert analysis, Cangnan total installed capacity of wind power can be developed about 80 million kilowatts, is expected to total investment of 10 billion yuan.
