Maintenance Manager to control operation and maintenance of offshore wind farms
Maintenance of wind farms is of increasing importance. Especially in remote areas, where logistics and accessibility are restricted, costs of preventive as well as corrective maintenance form a substantial part of the costs of electricity. The importance of a tool that assists in feedback to the design, failure logging, configuration control and maintenance planning is evident. This paper ...

At lofty heights: 3D Scan of a wind turbine blade
The maintenance of wind turbines, and whole wind farms, is a challenge. Normally wind turbines are designed to operate for 20 years. During these 20 years they are subjected to all kinds of weather conditions and heavy loads, but thanks to modern acquisition technology and advanced numerical models, such conditions can be addressed and even turned into increased annual energy production. To ...

As Europe extends turbine lifespans, data becomes crucial
Ageing wind assets, growing corporate demand and limited appetite for full repowering are favoring lifetime extension projects, increasing the importance of performance analysis. European lifetime extension (LTE) activity is set to hike in the coming years as feed-in tariffs expire and wind operators seek to maximize revenues from ageing assets. Around 4 GW/year of European wind turbine ...

Wind turbines and health
The American Lung Association's agenda for the new administration, Protect the Air We Breathe: An Agenda for Clean Air, states: "Climate, energy and clean air are inexorably linked. Solutions that lead to cleaner air must be included in any approach to cleaner, more efficient energy use and reductions in global warming." 1 Wind energy is one such solution - a clean energy source that can ...

10 Facts you didn’t know about Wind Energy
The oldest rotary windmills are considered to have been used regularly in agriculture and other purposes since 2000 B.C. by peoples of what would today be China and the Middle East who already sensed what the German physicist Albert Betz, the father of physics governing modern wind turbines, called The Theory of Wind Energy, presented and published in his book “Wind-Energie” at the ...

After Record 2012, World Wind Power Set to Top 300,000 Megawatts in 2013
Even amid policy uncertainty in major wind power markets, wind developers still managed to set a new record for installations in 2012, with 44,000 megawatts of new wind capacity worldwide. With total capacity exceeding 280,000 megawatts, wind farms generate carbon-free electricity in more than 80 countries, 24 of which have at least 1,000 megawatts. At the European level of consumption, the ...

Harmonic and interharmonic distortion analysis in the grid-connected wind electric generator
The operation of wind turbines has an impact on the power quality at the connected electric network. The integration of wind electric generators with the power grid becomes a headache for power engineers in several aspects. Harmonic distortion is one of the most important phenomena which affect the grid performance. This paper provides an in-depth discussion on harmonic and interharmonic ...

Maximum power point tracking for wind energy conversion systems based on fuzzy modelling and control
Wind energy conversion systems (WECS) have merits as environmentally friendly and renewable sources of energy. Because of its stochastic variations, power management concepts are essential to extract as much power as possible from the wind when it becomes available. The purpose of this paper is to present a TSK fuzzy model, which represents the turbine characteristic for maximum power point ...

Power curve measured and verified – Case Study
In 2010 RSE SpA (Energy System Research Inc.) within a Program Agreement with the Italian Ministry of Economic Development started a measurement campaign on a Libellula wind plant installed in Tuscany. The campaign lasted 1 ½ years and during this time RSE measured the turbine’s power curve following the requirements of the relevant IEC Standard ( EN 61400-12-1 – EN 61400-2). ...

Life cycle assessment of a 150 MW offshore wind turbine farm at Nysted/Roedsand, Denmark
The purpose of this life cycle assessment (LCA) was to illuminate and describe the potential environmental impacts caused by an offshore wind turbine farm (WTF) throughout its lifetime and use this knowledge in the planning and improvement of future WTFs. The LCA was based on experience from the LCA on Danish electricity and district heating [1] as well as the offshore WTF project at ...

The Real Cost Associated With Neodymium Wind Turbines
According to a research organized by a group of UK scientists, it is predicated that 15% of the country’s energy requirements in the year 2020 are expected to come from renewable energy sources. They have also considered about the wind farms that are popping in every corner of the country to come into this conclusion. These reports have created several contradictions among people as well. ...

Measuring Offshore Wind Resources
To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...
