CIVIL-469 / 4 credits

Teacher(s): De Almeida Manso Pedro Filipe, De Cesare Giovanni

Language: English


Summary

The course deals with the conception and design of hydraulic structures used for production and/or storage of electric energy, including pumped hydro energy storage (PHES). We discuss their technical/social/economical/environmental feasibility in the Swiss/European/Global energy transition.

Content

  • Assess the hydropower potential of a river reach
  • Distinguish the typology of hydropower schemes
  • Feasibility Design of small-hydropower schemes
  • Conceive low-head, mid-head and high-head schemes with/without storage
  • Assess the value of energy storage by pumping
  • Conceive hydropower batteries (pumped-storage), general layout and equipment.
  • Conceive pressurized hydraulic tunnels and shafts
  • Conceive measures against waterhammer, design of surge tanks.
  • Conceive water intakes in rivers, reservoirs and natural lakes
  • Define construction strategies to manage flood risks during construction
  • Adopt value-engineering measures to mitigate hydropower footprint on natural systems

The conception and design of hydraulic structures for hydropower implies using multiple skills to handle fluid-structure interactions, rock mechanics, design optimisation considering environmental, technical and socio-economic factors.

Keywords

Hydropower plants and batteries; hydropower potential, renewable energy, hydraulic tunnels & shafts, surge tanks, river diversion during construction, water intakes.
