Wind energy is considered a hope in future as a clean and sustainable energy, as can be seen by the growing number of wind farms installed all over the world. With the huge proliferation of wind farms, as an alternative to the traditional fossil power generation, the economic issues dictate the necessity of monitoring systems to optimize the availability and profits. The relatively high cost of operation and maintenance associated to wind power is a major issue. Wind turbines are most of the time located in remote areas or offshore and these factors increase the referred operation and maintenance costs. Good maintenance strategies are needed to increase the health management of wind turbines. The objective of this paper is to show the application of neural networks to analyze all the wind turbine information to identify possible future failures, based on previous information of the turbine. 展开更多

自然垄断理论是现代产业经济学(In-dustrial Economics)理论中发展较为迅速的一个组成部分。自然垄断理论的发展演进导致了20世纪70年代以来西方发达国家对许多过去被认为必须加以规制的产业部门都取消或放松了规制。在这一规制改革的背后,
