WATER HAMMER AND TRANSIENT ANALYSIS

  • Water hammer analysis in hydraulic piping systems of hydro power plants focused on the pressure rise or the pressure drop in a penstock and maximum transient speed increase of the hydraulic unit
  • Definition of necessary closing and opening time of hydraulic machines and main valves
  • Proposal of optimal water hammer protection such as necessary inertia moment of the hydroelectric unit, bypass valve and/or surge tank, etc
  • Determination of water column separation risk in the hydraulic machine penstock and the draft tube, including proposal of measures how to reduce or eliminate this phenomenon
  • Stability analysis of regulation in hydraulic piping systems  of hydro power plants
