Variable susceptance excitation control for dynamic performance improvement of a stand-alone wind turbine induction generator system
Isolated wind farms employ simple squirrel cage induction generators driven by variable speed wind turbines. Lacking control capability, such generation can contribute very little to network support. Wind turbines mostly do not take part in voltage and frequency control and if a disturbance occurs, the turbines may be disconnected and reconnected when normal operation has been resumed. From ...

Air concentrating nozzles: a promising option for wind turbines
Although the use of wind turbines has become necessary in many parts of the world, the actual developments in wind turbines do not concern countries where the average wind speeds are low. The paper introduces a new vertical axis wind rotor using a convergent nozzle for low wind speed areas. This paper brings a detailed theoretical and practical study of air concentrating nozzle and the optimum ...

Which is more efficient solar or wind energy?
Before we start our reasoning, we'd like to remind you that both are renewables, and therefore both are great energy options to turn to to improve our planet and to break our addiction to oil and gas. Today we will try to answer a question that we often ask ourselves when we are interested in renewable energies : between solar and wind energy, which is the most efficient? First, let's take a ...

A Few Things You Should Know about Carbon fibers
Carbon fiber is a new type of fiber material with high strength and with a carbon content of more than 95%. It is a microcrystalline graphite material obtained by piling up organic fibers such as flake graphite microcrystals along the fiber axial direction, and then undergoing carbonization and graphitization treatments. Carbon fiber is a new material with excellent mechanical properties. Its ...

Create new jobs & cut emissions by investing in renewable energy efficiency
At a time when major US companies are announcing job layoffs almost daily, the renewable energy industry is hiring new workers every day to build wind farms, install rooftop solar arrays, and build solar thermal and geothermal power plants. The output of industrial firms that manufacture the equipment for these energy facilities is expanding by well over 30 percent a year. These investments both ...
