Definitions

  • This invention relates not to the use of water turbine driven electrical generators for creating electrical power, but to the siting, positioning and design of the necessary
  • the system proposed in this invention utilises the efficient generation equipment of such schemes, but resolves the above problems by dividing the full barrier (1) into two sections (2) and separating them as shown in Fig.1.
  • the barrier can be moved off-shore and into deeper water as indicated in Fig.2.
  • the barrier (1) is formed between the coast-line (2) and an artificial off-shore island (3), constructed from concrete.
  • the proposed system is therefore driven by the Kinetic Energy of the water velocity. It can be shown that a velocity of 11 metres per second can produce as much energy as a 6 metres head of water. To obtain such a velocity from an average flow of 1 to 2 metres per second requires a gain by a factor of approximately 10.
  • Fig.2. shows the juxtaposition of the turbine/generator barrage (1), the coastline/river bank (2) and the artificial island (3), in relationship to the tide levels and flow. Since the system is scaleable to meet local power and other demands, the dimensions have all been normalised.
  • the water flow will be unidirectional and the profiles to maximise the venturi gains can be derived from Bernoulli's Equation. Statistically these diameters follow an approximate Rayleigh distribution.
  • the tidal flow is bidirectional and this requires that the Venturis should have a symmetrical profile.
  • Fig.2 shows that the island and coastal outline has been given an elliptical shape. This is to produce a primary venturi effect that will increase the flow rate of sea water through the turbines/generators. These are built into the barrage and housed within similarly profiled secondary venturi ducts. In particular, this helps to maximise the water flow rate at periods close to high and low water levels and under conditions of Neap tides.
  • the elliptical shape is a good compromise under

Abstract

L'usine hydroélectrique décrite, qui est représentée aux figures (1 et 2), est installée soit dans un cours d'eau ou un estuaire soit au large des côtes entre une île artificielle (3) et la ligne côtière (2). Les structures principales à la fois du barrage et des canalisations des turbines se composent de profilés en forme de Venturis, afin de maximiser la vitesse de l'eau. Les turbines sont disposées dans des canalisations profilées se trouvant dans le barrage (1) et reliant les deux structures. Les profilés sont conçus pour servir de Venturis primaire et secondaire, afin d'augmenter le débit de l'eau à travers les turbines, permettant ainsi une utilisation à la fois avec un écoulement d'eau bidirectionnel et unidirectionnel. Pour éviter les pertes périodiques totales de production de courant, qui se produisent dans les installations en estuaire et côtières actuelles aux périodes coïncidant avec des changements de flux des marées, on prévoit plusieurs stations hydroélectriques analogues pour profiter des phases marémotrices. En prévoyant trois stations placées aux endroits appropriés et avec leurs sorties reliées par une station de distribution centrale, on peut obtenir une production de courant en continu.
