Design Challenges in Hydropower Systems: Trade-offs and Difficulties in Operation
Hydraulic systems experience a variety of challenging conditions including hydraulic transients and oscillations. A long list of complex causes-including extreme pressures and resonance-can threaten power plants: the litany of failure is Both long and painful, but also instructive. In fact, it is estimated that more than 50％ of hydroelectric plants worldwide and other energy-related systems such as water transporting plants, water cooling system in nuclear and other thermal plants, oil pipelines, experience serious trouble or suffer severe operational constraints. We contend here that at least one problem is the presumption that comes from thinking that this is what a well-known and used technology, and thus we have grown inattentive. Moreover, we argue that a vigorous and reflective design and review procedure, diligently applied, would be a great assistance not only for the quality of projects but also to assist the education of the next generation of experts. Specifically, we believe that an appropriat e design, review, and trial operation procedure could have prevented many recent accidents and troubles.
