Small wind turbine emulator with armature controlled separately excited DC motor via analogue electronic circuit
In this paper, a small wind turbine emulator (WTE) using separately excited DC motor is modelled, designed, simulated, implemented and tested. A 1 HP separately excited DC motor is used to emulate the characteristics of the rotor of small wind turbine. The DC motor is driven by a thyristor bridge with closed–loop cascaded PI controller for armature control. A separately excited DC generator with ...

Dust control solutions for wind turbine rotor blade manufacturing
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 ...

Influence of exogenous and endogenous factors on the exergy analysis of 3–column array wind farm
Influence of exogenous and endogenous factors on the exergy analysis of 3 column array wind farm for two different layouts are highlighted in this paper. Nine turbines were placed in two different layouts to analyse the influence of exogenous factors such as wind velocity, wind direction, wind distribution and distance between turbines. Endogenous factors considered were diameter of rotor, hub ...

Performance estimation of HAWT blade using NACA airfoils
Wind energy is one of the developing resources of renewable energy. In order to increase the use of wind energy, development of wind turbine blade with higher power coefficient plays a vital role. The work being presented here is to give new design of blade for VESTAS V82–1.65MW (HAWT). In this work, NACA airfoils are used for the determination of aerodynamic performance characteristics of ...

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 ...

Look what’s cooking in the world of renewable energy
The solar and wind innovations that got us where we are today — and those waiting in the wings — point to a hopeful future. Inside a sprawling single-story office building in Bedford, Mass., in a secret room known as the Growth Hall, the future of solar power is cooking at more than 2,500 °F. Behind closed doors and downturned blinds, custom-built ovens with ambitious names like ...

Tech-Deep-Dive: How Kitekraft Solves Aerodynamics
Aerodynamics is an interesting and one of the most challenging fields of science and engineering. You can even win $1 million if you can contribute to the understanding of the underlying math. Aerodynamics is generally described with the Navier-Stokes-Equations, but even the fastest super computer in the world is not capable to solve these equations directly for a reasonable engineering problem. ...
