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 ...

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). ...

Productivity of small wind turbines for various wind potentials conditions: application in Bulgaria and Corsica
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 ...

New future for small and medium size wind turbines in Belgium!
‘More wind turbines in a shorter period of time’, those were the main principles in the ‘Windpower 2020’ wind plan by Flemish Minister of Energy Bart Tommelein and his colleague Joke Schauvliege from the department ‘Environment (CD&V)’. Steps have already been taken to remove a number of obstacles for the construction of wind turbines. Minister Tommelein ...

Efficiency stimulus will lower energy bills, says federal report
Depending on your position, the federal stimulus money is either a jobs builder or a national budget buster. The Energy Information Administration offers another take. In a recent analysis, the EIA finds that stimulus money should reduce what consumers and businesses pay to heat, cool and light buildings. The federal agency this month updated its annual energy outlook to compare how energy ...

A small island in the Indian Ocean offers big lessons on clean power
The Indonesian island Sumba is working to provide 100% renewable electricity to all 650,000 residents by 2025. As the sun sets on the small Indonesian island of Sumba, Danga Beru Haba begins weaving under the glow of a single incandescent lightbulb, the only one in her home. Although she is tired from working dawn to dusk in the fields surrounding her village of Kampung Kalihi, the sarong she is ...

US plant shutdowns, grid focus drive storage growth: Greensmith CEO
Power plant closures and hiking transmission costs are driving up US utilities’ investment in renewable energy storage, John Jung, CEO of Greensmith, an energy storage services firm, told Wind Energy Update. Some 60 GW of US coal-fired capacity is set to close between 2012 and 2020, according to the EIA. Nuclear plant lifespans will end and the US plans $180bn in planned transmission ...

Multi-criterion optimization of energy management in drinking systems
In this study, two different energy sources that are connected to a pumped storage water supply system are analyzed: a water and a wind turbine. A water turbine can be integrated in a water supply system in high-pressure locations. Recently, new sources of energy production are being researched and applied due to the increase in the price of conventional energy sources and concerns regarding the ...
