  • Large-scale hydropower system optimization using dynamic programming and object-oriented programming: the case of the Northeast China Power Grid

    This paper examines long-term optimal operation using dynamic programming for a large hydropower system of 10 reservoirs in Northeast China. Besides considering flow and hydraulic head, the optimization explicitly includes time-varying electricity market prices to maximize benefit. Two techniques are used to reduce the ‘curse of dimensionality’ of dynamic programming with many ...

  • Side Core Pulling Mechanism

    The flanks of plastic parts are usually provided with holes or flutes. Under such conditions, side-direction forming cores must be used to form plastc parts. However, such cores must be developed into active parts so that they can be pulled out prior to the stripping of plastic parts. The mechanism for pulling out and restoring such active cores is called  ...

  • 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 ...

  • Monitoring Hydroelectric Dam Sumps - Case study

    The Situation Hydroelectric dams produce electric power by harnessing the force of the water flowing through the dam. There are numerous sources for oil spillage: The hydroelectric turbines are lubricated by lubrication oils. The very large water control valves are normally hydraulic powered and are lubricated with various greases and oils. Vehicles ...

  • 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 ...
