  • GE Leakwise Application Notes: Oil Detection in Hydro-Electric Power Plants

    Leakwise* Oil Detection in Water Collection Sump Under Turbines Water carries oil leakage from turbine bearings and other leaking sources into a large sump, which is built under the turbines. In most plants, pumps installed at the bottom of the sump discharge the water directly to the river.  A Leakwise lD-221 Floating Oil Detector is installed in a perforated 6” stilling well. The ...

  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...

  • Clean power in water supply systems as a sustainable solution: from planning to practical implementation

    Energy efficiency and renewable energy sources have drawn a greater attention by EU, in particular for climate change policies as it can substantially cut down CO2 emissions to meet EU environmental obligations. It is well established that in drinking pipe systems Pressure Reducing Valves (PRV) are used as a mean for excess energy dissipation for the purpose of pressure control. This type of ...

  • Modelling of the hydro-generator local network operation and load disturbance rejection

    The paper describes models of the local network operation of the hydraulic turbine-generator unit. Two different models are proposed. They describe the dynamic behaviour of a system in which the unit is connected to an equivalent system. A nonlinear model of the interconnection to an equivalent power system is considered. An optimal controller for load disturbance rejection in water turbine speed ...

  • 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 ...

  • Invasion of the non-indigenous nuisance mussel, Limnoperna fortunei, into water supply facilities in Japan

    The aquatic nuisance mussel, Limnoperna fortunei, arrived in Japan before 1987 possibly with the Asian clam imported as food from mainland China. Now the mussel’s distribution has spread to two river systems in central Japan. Water authorities reported several cases of damage caused by L. fortunei. Most cases of damage were caused by dead mussels clogging small diameter pipes for raw water ...

  • Oil Filter Elimination

    The need to state strictly and accurately the procedures for the collection and elimination of car oil filters is a topical subject, due to the injuries to health and environment that would be caused by an inappropriate storage and elimination. According to the Italian law, the expression “exhaust oil” identifies any  industrial oil or lubricant with a mineral or synthetic basis which is no more ...

  • Oil and water don`t mix

    Small spots of motor oil on your driveway look tacky enough. Leaks of hydraulic oil from the hydro turbine of a big pumped-storage plant are not only more noticeable, but they also could end up in the facility's sump or in its reservoir, as well. At the Blenheim-Gilboa Pumped Storage Power Project in New York's Catskill Mountains, there's another reason leaks are unacceptable. The New York Power ...

  • 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 ...
