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. ...

A wind energy conversion system (WECS) differs from a conventional power system. The power output of a conventional power plant can be controlled whereas; the power output of a WECS depends on the wind. This nature of WECS makes it difficult for analysis, design and management. Various approaches have been developed to study the behaviour of WECS. In this paper, the steady-state characteristics ...

Less or more accurate power curve models are generally used to simulate the wind turbine electrical production versus the available wind speed. However, if such models are adapted to large machines, this is not the case for small ones. The objective of this paper is to study the impact of different small-scale wind turbines power curves and wind distributions on the electrical production. An ...

Wind turbine rotor blade manufacturing involves incessant grinding passes that create large quantities of particulate and require innovative dust control solutions. Rotor blades usually range between 30 and 60 meters long. Made by layering thousands of thin filaments impregnated with epoxy resin, the rotor blades have to be reduced to the proper dimensions and prepared to accept the next layer ...

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 ...
