  • How a Specialized Automatic Control Valve Solved Flooding

    The Colombian area of Antioquia creates much of its clean power from hydropower plants along the Guadalupe River. The Guadalupe IV hydroelectric plant generates power with three vertical axis turbines that discharge water below the river level. To prevent flooding, however, the plant needed a solution that ensured the ejector ...

  • Controlling the power balance in an 'empty network'

    This paper presents the concept of an 'empty network' and shows how the power balance can be controlled in such a system. In this study, an 'empty network' is defined as a transmission system in which no rotating mass is present. All generators are connected to distributed systems and 'hidden' behind power electronic interfaces. One generator creates a neat 50 Hz voltage that serves as a ...

  • Agents controlling the electric power infrastructure

    The electric power grid is evolving from a centrally controlled grid with only a handful of regulated monopolies to an open, liberalised electricity market. In addition, more and more small-scale dispersed generators are deployed in distribution nets. This puts extra stress on the power grid, in an era when electricity is one of the most important commodities for economic, industrial and everyday ...

  • Permit Compliance Monitoring for the Power Generation Industry

    The Clean Air Act Amendments (CAAA) of 1990 authorized EPA to develop regulations requiring facilities to monitor the adequacy of emission control equipment and plant operations. This paper discusses the various methods available for coal-fired power plants and gas turbine installations to demonstrate a reasonable assurance of facility compliance with emission limitations, and ensure that control ...

  • First commissioned LFG power generation unit in Iran

    The first landfill gas (LFG) power generation station in Iran was officially commissioned in July 2009. This plant is located in old landfill site of Mashhad, the second largest city in Iran. This landfill has been receiving municipal solid wastes (MSW) since 1975 but the first activity for biogas extraction in this site was started in 2000. The LFG extraction system in this site is based on ...


  • Spin Ice Revolutionizing Power Source Generation

    A recent discovery has enticed physicists to begin to reorder their understanding how energy particles behave after a thrilling find where a magnetic equivalent has been found to actually be able to create a particle charge much along the same lines as electricity. Spin ice, as its known, creates single controlled bursts of charges much the same as electricity, with similar behaviors and ...

  • Control and protection of distribution systems with distributed generators

    Unquestionably, in the last years, the number of generators connected directly to electric power distribution systems has increased. In addition, the main statistics and signals show that such tendency could become even more intense in the coming years. As a consequence of this policy, many technical factors related to control, protection, operation and analysis of distribution systems should be ...
