Wind Power Embraces a Promising Marketplace Prospect
Wind power technology is originated from Europe as well as the worldwide wind power market place realized a rapid annual typical growth rate of over 30 percent in 1990s. The growth rate dropped a little bit following 2000 as a result of the gradual industry saturation. The worldwide wind power market place, Vertical Mill Drives entered yet another round of high-speed development immediately after 2005. It's estimated that the worldwide wind power installation capacity will reach 1.231 billion KW in 2020 and at that time wind power will account for twelve percent of global electrical energy supply. It can be calculated that the driving force for the twenty percent typical growth rate comes from Asian and American regions.
Asia will grow to be the leading and dominant area for global wind power sector within the following twenty yrs. Adopting measures to forecast wind circumstances, optimize warning mechanism and facilitate automatic protection is now the key to ensuring the secure and stable operation of wind turbine. Big scale and offshore wind power plants will turn out to be the grant future development trend of worldwide wind power, Gear Speed Reducer. Wind power gear manufacturing technologies is some multi-disciplinary integrated technology combing the mechanism of different subjects such as aerodynamics, material mechanics, meteorology, electric machinery, power transmission and protection & control. The longevity of wind power equipment design is frequently longer than 25 to 30 yrs, subjects to the damage imposed by wind, rain, sunlight, thunder, ice and salt corrosion. Japan has witnessed many times a year its wind power gear like Gearboxes for Wind Turbines to become destroyed by typhoon and thunder. A wind power company in Denmark has once replaced eighty wind turbine gearboxes, undergoing huge losses. Yet another wind power equipment producer was forced to the verge of bankruptcy right after having compensated the loss of the buyer because of a damaged wind power gear component. The occurrence of motor failure and also other technical failure in multiple unites of an offshore wind farm has incurred the supplier to shoulder over 40 million Euros of disassembly cost in order to replace the fan and have the gear transferred to inland for repair. Currently, there are over 80 thousand wind power equipments inside the world. Wind power market is developing at an annual growth of 25 to 30 percent, increased by 15 times, twenty times in Europe inside the fifteen years since 1999. However, the overall growth and development of wind power is very uneven; Germany, Spain, America, Denmark and India embrace fastest wind power development with their wind power capacity accounting for over eighty percent of total wind power capacity within the globe.
