Explanations

General:

• A: ID of the hydraulic element
• B: ID of the control function which supplies the tailwater level (e.g. "y02")
• C: Identifier: Calculation-type: 1: weir overflow, 2: pipe, 3: turbine

Weir overflow:

• D: Weir form [1-5]:
  • 1: wide-crested
  • 2: roof-shaped
  • 3: Height/Width = 1
  • 4: Height/Width < 0.4
  • 5: sharp-edged
• E: Weir crest [müNN]
• F: Weir width [m]
• G: weir coefficient [-] 0 < µ ≤ 1
• H: flexible/movable weir: ID of the control-function(e.g. "y02"),whichs value shall be subtracted from the weir height.(refer to Hints).

Pipe(s): if there are several pipes one after another the following pipe sections are to be written into the next line (without a new HYA ID)

• I: Height of the inlet edge
• J: Pipe length
• K: Pipe diameter
• L: Cross-section area (if K is given, the cross-section area is not needed)
• M: Perimeter (if K is given, the perimeter is not needed)
• N: Roughness coefficient
• O: Coefficient of loss (Inlet losses)

Turbine:

• P: Turbine capacity [kW]
• Q: Turbine absorption capacity [m³/s]
• R: Minimum flow rate [m³/s]
• S: Inlet height [müNN]
• T: Coefficient of losses [-] 0 < η < 1
• U & V: Minimum 2 rows with supporting points for the efficiency-curve ηT=f(Q/Qmax) of the turbine

Hints

Tailwater level for turbines and weirs

A Tailwater level is supplied by a control-function (system status). The ID of the desired control-funtcion must be named in the column WSP unten. The IDs of the control-functions are assigned in the KTR-File.

If no tailwater level is supplied, the tailwaterlevel will be determined as a MIN_mNN, which is a constant with the value -490 müNN.

Lowerable weir

A lowerable weir can be implemented by writing the ID of a control-function (refer to KTR-File) into the column Fak hue. The value/factor from the control-function will be subtracted from the normal weir crest for each time increment (not multiplied).
