  • 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 ...

  • Wind Generators as Role Models

    Advanced speed control methods are available for the regulation of wind generators. Working together with SET Sustainable Energy Technologies GmbH, Sulzer made use of one of these new concepts on pumps for the first time and implemented it with great success on a feedwater pump in a refinery. Unregulated pumps consume unnecessary drive energy when demand fluctuates. By controlling ...

  • Induction motor model selection criterion for parameter estimation in speed sensorless drive

    In the parameter estimation algorithm of speed sensorless induction motor drive, the complete model of induction motor is replaced with its reduced order model by many researchers. However, no guideline is available in the literature for the selection of appropriate model under various operating conditions. In this paper, a detailed investigation is done regarding the possibility of such ...

  • Design of simulator for modelling of wind turbine and transfer of maximum power using buck-boost converter

    A small wind turbine simulator based on a separately excited DC motor-permanent magnet synchronous generator (PMSG) set has been proposed to evaluate the performance of the small wind turbine model. A DC shunt motor is used to produce varying aerodynamic power by varying field current with the help of an IGBT switch. The simulator is an equivalent gearless wind turbine model that fluctuate ...

  • Power conditioning of an uncontrolled micro-hydroturbine-driven induction generator for distributed generation using a battery energy storage system

    Distributed Generation (DG) and its interconnection to the AC power grid is a relatively new concept. DG employs small generators, which are distributed throughout the power system. The electricity is usually generated by renewable energy sources such as wind, hydro and tidal, which are intermittent in nature. These generators connected to the AC grid may lead to severe power quality problems. ...

  • Realizing energy savings in water processing applications using medium voltage adjustable frequency drives

    Why uptime and energy efficiency matter in water processing Making sure that systems and processes are up and running while improving energy efficiency (and cost) is crucial in water processing applications. During the recent recession, federal and municipal budgets tightened, limiting access to capital across the United States. At the same time, increased awareness of the ...

  • Toasting Pop-Tarts cheap: How electricity may solve our energy woes

    We tend to talk about electricity in terms of its problems — it degrades the environment, costs too much and messes up scenic views. But the Manhattan Institute’s Peter Huber takes a different stand in his new report “The Million-Volt Answer to Oil.”Huber says electric power may be the cheap, efficient resource we seek to give America energy independence. He divides energy into two camps: ...

  • Building New Industries and Creating New Jobs in a Plan B Economy

    Building a new economy, one that can sustain economic progress, involves phasing out old industries, restructuring existing ones, and creating new ones. This new economy will be powered by renewable sources of energy, will have a more diverse transport system--relying more on rail, buses, and bicycles, and less on cars--and will recycle everything. For example, coal use will be phased out, ...

  • A new application of hydrogen

    A new application of hydrogen is being deployed which is helping solve humanity’s ever-evolving energy woes. Traditionally, hydrogen has a large number of applications – used in everything from industrial products to food packaging. Ammonia used in fertilizer and industrial processes amounted to 160 Million tons worldwide in 2011; hydrogen is a primary component in ammonia. The market ...

  • On energy, we`re finally walking the walk

    The United States has entered a new energy era, ending a century of rising carbon emissions. As the U.S. delegation prepares for the international climate negotiations in Copenhagen in December, it does so from a surprisingly strong position, one based on a dramatic 9 percent drop in U.S. carbon emissions over the past two years and the promise of further huge reductions. Prominent among these ...


  • U.S. headed for massive decline in carbon emissions*

    For years now, many members of Congress have insisted that cutting carbon emissions was difficult, if not impossible. It is not. During the two years since 2007, carbon emissions have dropped 9 percent. While part of this drop is from the recession, part of it is also from efficiency gains and from replacing coal with natural gas, wind, solar, and geothermal energy. The United States has ended a ...

  • The Developing Role of Permanent Magnets in Renewable Energy

    The developing role of Permanent Magnets in renewable energy production along with the environmental protection is a very worthy topic. An upright permanent magnet should produce a high magnetic field with a near to the ground mass, and should be constant against the inspirations which would demagnetize it. The desirable properties of such magnets are usually indicated in expressions of the ...

  • Are you eligible for a manufacturing tax credit?

    The United States has been generous with tax credits for energy production. But until now, it’s been somewhat miserly about giving breaks to those who make the equipment that makes the energy – or saves it.That’s changed with creation of the Advanced Energy Manufacturing Credit (MTC), part of the federal stimulus package. The 30% tax credit makes $2.3 billion available for new, expanded, or ...

  • Green Futures Rely on Strong Magnets

    When lodestone was first discovered before the 1800s people were amazed at this rock that got attracted to itself. They noticed that it pointed to a specific direction every time it was suspended freely or was placed on water. This led to its use in the first compass to give sailors direction as they went for expeditions at sea. Further investigations led to the production of stronger ...

  • “Green” innovations: fashion or necessity?

    Why alternative “green” energy is crucial today? Public awareness of the global energy challenge is at a very high level, at least in the U.S., where I live, even though we do not have an energy crisis of the type that we saw in the 1970’s. Energy prices, e.g. for gasoline and electricity, are reasonably stable, and there are no supply shortages like the ones that led to ...


  • A new EE resource: Distributed people

    Energy efficiency is often described as the invisible resource. It improves our energy supply without any of the usual industry trappings: smokestacks, wind turbines, transmission lines and poles. This is one of its virtues.But efficiency’s invisibility also causes problems. Because it operates out of sight – inside walls, underneath lampshades, and in factory motors — efficiency tends to attract ...
