Abstract

The motivation for this work is present in the wind industry, the future large-scale offshore wind farms require more advanced testing and maintenance program development. Possible economic advantage, if the assessment is a sensor network remote central control station from the shore turbines each person's status, and physical examination before starting the repair was to identify specific requirements.

Three objectives of this project;

First, to develop wind turbine blades on the sensor used in remote monitoring applications a practical method

Secondly, the characteristics of different types of damage based on outputs of sensors

Third, develop a way to estimate the remaining life of a blade inside, based on the distribution of that damage

Research Proposal

Background

Harnessing wind energy has been known for more than 2,000 years, taking in Asia and the Middle East began to use windmills to grind grain products and to pump water. At the end of the 1800s began experimenting with electricity production using wind turbines. Thus started the American Charles F. Brush in 1887 so act belt of what is known as the world's first automated wind turbine for electricity production. The turbine could deliver a power of 12 kW.

Denmark was the start of promotion within the development of this new technology. The 1890s began the Dane Poul la Cour following construction of a series of test turbines for electricity production, which meant that in 1918 could cover approx. 3% of Danish electricity consumption through wind energy. It was not until 1970 that electricity production using wind really came under the spotlight. This was not least the oil crisis in 1973 and later again in 1979. Combined with an increased focus on environment and general public opposition against government plans to use nuclear power, this led to increased pressure to develop alternative renewable energy sources. This has meant that Denmark today is a leader in wind technology and consistently producing more powerful turbines.

Windmills have undergone a dramatic development, as reflected in their increased power. In 1980, a typical turbine thus deliver 22 kW, where the newly mills today (2004) typically deliver 3 MW. The evolution continues and the first wind turbines of 5 MW is already close to being fully developed. It is estimated that one in 15 years could be set up mills with a capacity of 20 MW.

Commercial-scale offshore wind power generation facilities currently in shallow waters off the coast of Europe operations, but further technical development is the outer continental shelf (OCS) requires the use of deeper waters.

Wind is the movement of air. As the Earth's surface of various land and water formations, it absorbs solar radiation uneven. Wind is produced by the sun heating the Earth's surface unevenly. Land, wind power has been used to generate electricity for more than two thousand years. In modern times, mainly for wind power ...
