Hydro Design

Heidra has developed a modular approach to the complete M3H design. Components include:

• Intake: In general self cleaning intakes are used which avoid the need of either regular maintenance or power assisted cleaning devices. A suitable choice of intake to maximise power production and minimise abrasive particles entering the turbine is essential for the smooth functioning of a micro high-head hydro (M3H) electric system.
  
  
• Penstock (pipeline): M3H systems can experience pressure surges due to blockages at the turbine nozzle. These surges can produce a pressure wave which passes up the pipeline and instigate rapid fracture. Dr Steve Ritchie studied such failure mechanisms whilst employed as a researcher at Imperial College, London. Heidra's design ensures against the risk of such failure. We will specify the most appropriate, cost-effective pipeline and supporting structures for your system.
  
  
• Turbine: Heidra has developed its own Optiflow T17 turgo turbine for M3H systems. The turbine includes a high efficiency, brushless induction generator.
  
  
• Control System: Using the same tried and tested head sensor used to monitor flow, Heidra will ensure your M3H scheme generates maximum power over the full range of the flow duration curve.
