  • No Place Is Too Far

    The remote location of hydropower stations is often a great challenge when major repair work is necessary. The refurbishment of a large generator in the Scottish Highlands shows how Sulzer finds cost-effective service solutions even in places miles from nowhere. Much of the UK hydroelectric capacity was built during the 1950s. These installations have performed extremely well, especially ...

  • Turbine Inspection

    Recent advances in natural gas exploration and extraction technology have led to skyrocketing projections of the amount of recoverable natural gas within US borders. This energy boom will result in the expanded use of gas-fired power plants to provide electricity to US homes and businesses over the coming decades. Not only does this mean cleaner and more abundant energy for the US environment and ...

  • Pumped hydro storage softens blow of wind imbalance penalties

    Quarry Battery is developer of the £160 million ($249.2 million) Glyn Rhonwy pumped hydro facility in Wales which will be the UK’s first grid-scale electricity storage facility for decades. The facility will produce nearly 50 MW of electricity using pumped hydro technology. As more fossil fuel-fired generation is taken offline and wind capacity grows, grid operators will ask wind ...

    DSEP100 Mains Decoupling Relays for hydropower projects in remote locations in the Cumbrian Lake District, UK.  Old decommissioned water wheels in Ambleside, Blencathra and Langdale have been recently refurbished and brought back into use as sophisticated hydropower turbines which are now working in parallel with the grid, ...

  • Generating Ecological Gains from Hydro-Electric Power - Case Study

    NCC has worked with Eskom to mitigate the environmental impacts of the Ingula Pumped Storage Scheme on a sensitive wetland site in the Little Drakensberg/Escarpment, including creating and managing a new conservation area. South Africa’s energy demand is growing at rates of around 5% a year, placing enormous pressure on Eskom not only to create new generating capacity, but also to manage ...

  • Kelag demonstrates hydro power know-how in Bosnia-Herzegovina

    Austrian energy companies are increasingly helping to expand the hydro power capacities in the Balkans. On the River Ugar, which today marks the border between the Federation of Bosnia-Herzegovina and the Republic of Srpska, the Novakovici runof- river power plant has been delivered by a subsidiary of the Carinthian utility company Kelag, InterEnergo. In a normal year, the high-pressure plant, ...

  • The Real Cost Associated With Neodymium Wind Turbines

    According to a research organized by a group of UK scientists, it is predicated that 15% of the country’s energy requirements in the year 2020 are expected to come from renewable energy sources. They have also considered about the wind farms that are popping in every corner of the country to come into this conclusion. These reports have created several contradictions among people as well. ...

  • Are wind turbines economically viable in Britain?

    If Britain establishes wind energy as their main energy source, they will be able to create a large number of new job opportunities. This can provide a huge influx of job opportunities in the short run since the implementation of wind turbines require a lot of manpower. Moreover, the maintenance of these wind farms can give life to a considerable amount of sustainable jobs. Monitoring the wind ...

  • A new design of a highly efficient hydraulic turbine on the basis of the specific hydrodynamic effect

    Traditional free flow turbines slow down water stream using its kinetic energy. This article describes a method for deriving energy from a free water stream using a unique hydraulic turbine which unlike traditional hydraulic turbines speeds up the water stream using potential energy thanks to a specific hydraulic effect. The article also describes a method of mathematic calculations of output ...

  • VSC with a T-connected transformer-based electronic load controller for an isolated asynchronous generator feeding three-phase four-wire loads in a micro hydro system

    This paper deals with a novel solid state controller (NSSC) for isolated asynchronous generator (IAG) feeding three-phase four-wire loads driven by constant power prime movers, such as uncontrolled micro hydro turbines. AC capacitor banks are used to meet the reactive power requirement of the asynchronous generator. The proposed NSSC is realised using a set of IGBTs (insulated gate bipolar ...

  • Exergy analysis of gas-turbine systems with high fogging compression

    Gas-turbine cycles with high fogging compression could offer enhanced efficiency and low complexity. Whereas compression power and heat rates decrease when small amounts of water (up to 2% of air flow by mass) are injected at the machine inlet, increased injection amounts could allow implementation of regeneration, further decreasing the heat rate. In this study, an exergy analysis is carried out ...

  • 1997 IFAI award devil Canyon hydroelectric power plant, San Bernardino, California - Case Study

    Constant demands for water and electricity in heavily populated areas in California prompted the Devil Canyon Power Plant project. Constructed from 1969 to 1974, the power plant is located at the San Bernardino Mountains near the mouth of Devil Canyon. With two pipelines carrying water from Silverwood Lake, an elevation drop of almost 1500 ft (460 m) between the lake, and four Pelton wheel ...

  • In situ weld repair of blade tenon of steam turbine in a power plant

    During one of the routine inspections in a nuclear power plant, it was found that a tenon of one of the third-stage blades of the Low-Pressure (LP) turbine had been worn/broken off the turbine blade, leaving only the remaining tenon riveted to the shroud piece. With only one of the two tenons remaining, the blade was at risk of getting freed from the shroud piece. Hence, it was necessary to ...

  • Installing an ESD LH1000 A Micro hydro Evolution Article describing the installation of an ESD LH1000 low head machine

    Every morning, before brushing teeth or having a look at the weather outside our Victoria, Australia, off-grid home, my wife Carrie or I pad downstairs to the battery room to check the meters that monitor our electrical system. The reading determines whether we use the propane stove or the electric jug to heat water for our tea. Since our microhydro plant upgrade, it’s usually the jug. ...

  • 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. ...

  • A Review of Cavitation-Erosion Resistant Weld Surfacing Alloys for Hydroturbines

    AbstractAn improved weld surfacing alloy has been developed and tested to resist cavitation-erosion in hydroturbines. Typical wear characteristics experienced in laboratory testing has been correlated to actual service conditions. A metallurgical evaluation shows that a high strain, work hardening austenitic stainless steel produces superior resistance to cavitational erosion. Several industrial ...
