  • Minimum Flow Units - Case Study

    Environmental regulations are becoming more stringent and the minimum by-pass flow requirements are generally increasing in North-America. Many of our small hydro technologies are perfectly suited for this type of application whether it is to replace an existing pressure reducing valve or implement a new turbine upstream of the by-passed reach of an existing hydro plant. Shown below is an example ...

  • 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 ...

  • Micropower system modeling with Homer

    The HOMER Micropower Optimization Model is a computer model developed by the U.S. National Renewable Energy Laboratory (NREL) to assist in the design of micropower systems and to facilitate the comparison of power generation technologies across a wide range of applications. HOMER models a power system's physical behavior and its life-cycle cost, which is the total cost of installing and operating ...

  • 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 ...
