Pump Properties

Acceleration time

Set the constant flow rate

Calculated Discharge derivative with DownStreamWaterLevel. Downstream is relative to the direction of chainage. The value is calculated by SetWaterLevels. Unit: [m^2/s]

Calculated Discharge derivative with UpStreamWaterLevel. Upstream is relative to the direction of chainage. The value is calculated by SetWaterLevels. Unit: [m^2/s]

Deceleration time

Calculated Discharge. The value is calculated by SetWaterLevels. Unit: [m^3/s]

Must be set to true to activate (external) control of discharge (through a PID control or similar).

If pump is controlled through ControlMoudle, this will set this automatically (during Prepare)

Can not be combined with StartStopLevelControlActive

Downstream water level.Downstream refers to the direction of chainage. The water level is set by use of SetWaterLevels Unit: [m]

Property used by (de)serializer, when it can not find proper target for a data field. Support of forward compatible data contracts.

Flow area through structure. Used by most (but not all) structures.

QH relation for QdeltaH and QH pumps, (dH, Q) or (H, Q) pairs. The XYTable ensures that dH (or H) is always increasing.

For QdeltaH, a positive dH is the height that water must be RAISED across the pump.

For a PID controlled pump (DischargeControlActive == true) this HQ relation is the maximum pump capacity. Set to null if no maximum capacity.

QH relation for QH and QdeltaH pumps Minimum discharge allowed for a PID controlled pump.

Structure ID

Used to get a consistent description of the structure. The ID comes in user units. Used e.g. when reporting errors, warnings and hints.

Flag to control if the structure is implicit or explicit. If the structure is explicit (Implicit == false) then the derivatives of the dicharge are always zero. Default value: true

Invert level down stream

Invert level up stream

Return true if the pump is pumping

A side structure is connected to a reservoir downstream (chainage direction).

True if the pump supports variable speed operation (must be true for PID controlled pumps). Default value: false

Length of the structure. Unit: [m] Default value: 0m

Location property.

Maximum stop level used if an external control is active. If an external control is active, then MinStopLevel and MaxStopLevel must be set.

Minimum stop level used if an external control is active. If an external control is active, then MinStopLevel and MaxStopLevel must be set.

Minimum time the pump should stay off if it stops pumping. Default value is 0 seconds.

Minimum time the pump should stay on if it starts pumping. Default value is 0 seconds.

Number of times the pump was started

Offset on water level

Offset to use when looking up the minimum discharge for the pump. Only used when a PID control is attached to the pump.

Set the level of the outlet for the pump.

For side structures (StructureType == SideStructure) this is also used as a reservoir level, i.e. a level outside the model. If flow direction is upstream (all negative Q in HQRelation), then the downstream level is equal to this reservoir level. If Q is positive, then OutletLevel is used as the downstream end.

Default value is MinValue, effectively disabling the use of the OutletLevel

Type of pump

Same as OutletLevel

The getter is used to get a list of errors.

Bank side that side-structure is located on

If side structure contains reservoir, and has the Coordinate set, this is not used (and should be set to Undefined).

Reservoir at end of side structure. Null if not side structure, or no reservoir is defined

The water level at which the pump is activated

Must be set to true to activate external control of start and stop levels (through a PID control or similar).

If pump is controlled through ControlMoudle, this will set this automatically (during Prepare)

Can not be combined with DischargeControlActive

The water level at which the pump is de-activated

Type of structure

String used to identified cross sections

Total time the pump was active

Structure type, unique for each structure.

Upstream water level. Upstream refers to the direction of chainage. The water level is set by use of SetWaterLevels Unit: [m]

If true, then the maximum alloved discharge is taken from the MaxPumpDischargeUpstream/MaxPumpDischargeDownstream and that value is use to directly set the maximum discharge. Default false.

If true, then suppresion factors from the PumpSuppressionFactorUpstream and PumpSuppressionFactorDownstream delegates are used to limit the available discharge of the pump. Default false.
