Pump Properties

The Pump type exposes the following members.

Properties
  NameDescription
Public propertyAccelerationTime
Acceleration time
Public propertyConstantFlow
Set the constant flow rate
Public propertyCurrentStartLevel
Current start level of pump. Initially the same as StartLevel, but may be changed during the simulation by various control strategies.
Public propertyCurrentStopLevel
Current stop level of pump. Initially the same as StopLevel, but may be changed during the simulation by various control strategies.
Public propertydDischargedDownStreamWaterLevel
Calculated Discharge derivative with DownStreamWaterLevel. Downstream is relative to the direction of chainage. The value is calculated by SetWaterLevels. Unit: [m^2/s]
(Inherited from Structure.)
Public propertydDischargedUpStreamWaterLevel
Calculated Discharge derivative with UpStreamWaterLevel. Upstream is relative to the direction of chainage. The value is calculated by SetWaterLevels. Unit: [m^2/s]
(Inherited from Structure.)
Public propertyDecelerationTime
Deceleration time
Public propertyDischarge
Calculated Discharge. The value is calculated by SetWaterLevels. Unit: [m^3/s]
(Inherited from Structure.)
Public propertyDischargeControlActive
Must be set to true to activate (external) control of discharge (through a PID control or similar).

Can not be combined with StartStopLevelControlActive

Public propertyDownstreamWaterLevel
Downstream water level.Downstream refers to the direction of chainage. The water level is set by use of SetWaterLevels Unit: [m]
(Inherited from Structure.)
Public propertyExtensionData
Property used by (de)serializer, when it can not find proper target for a data field. Support of forward compatible data contracts.
(Inherited from Structure.)
Public propertyFlowArea
Flow area through structure. Used by most (but not all) structures.
(Inherited from Structure.)
Public propertyFlowFactor
The discharge (and discharge derivatives) are scaled by the flow factor.
(Inherited from Structure.)
Public propertyHQRelation
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.

When DischargeControlActive is set (e.g. PID controlled pump) this HQ relation is the maximum pump capacity. Set to null if no maximum capacity.

Public propertyHQRelationMinimumCapacity
QH relation for QH and QdeltaH pumps Minimum discharge allowed for a discharge controlled pump (e.g. PID). Set to null to disable.
Public propertyID
Structure ID
(Inherited from Structure.)
Public propertyIDInUserUnit
Used to get a consistent description of the structure. The ID comes in user units. Used e.g. when reporting errors, warnings and hints.
(Inherited from Structure.)
Public propertyImplicit
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
(Inherited from Structure.)
Public propertyInvertLevelDownstream
Invert level down stream
(Overrides StructureInvertLevelDownstream.)
Public propertyInvertLevelUpstream
Invert level up stream
(Overrides StructureInvertLevelUpstream.)
Public propertyIsActive
Return true if the pump is pumping
Public propertyIsSideStructure Obsolete.
A side structure is connected to a reservoir downstream (chainage direction).
Public propertyIsVariableSpeed
True if the pump supports variable speed operation (must be true for PID controlled pumps). Default value: false
Public propertyLength
Length of the structure. Unit: [m] Default value: 0m
(Inherited from Structure.)
Public propertyLocation
Location property.
(Inherited from Structure.)
Public propertyMaxStartLevel
Maximum start level used if an external control is active. If an external control is active, then MinStopLevel and MaxStartLevel must be set.
Public propertyMinStopLevel
Minimum stop level used if an external control is active. If an external control is active, then MinStopLevel and MaxStartLevel must be set.
Public propertyMinTimeOff
Minimum time the pump should stay off if it stops pumping. This is only applicable when StartStopLevelControlActive. Default value is 0 seconds.
Public propertyMinTimeOn
Minimum time the pump should stay on if it starts pumping. This is only applicable when StartStopLevelControlActive. Default value is 0 seconds.
Public propertyNumberOfStarts
Number of times the pump was started
Public propertyOffset
Offset on water level
Public propertyOffsetMinDischarge
Offset to use when looking up the minimum discharge for the pump. Only used when a PID control is attached to the pump.
Public propertyOutletLevel
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

Public propertyPumpType
Type of pump
Public propertyReservoirLevel
Same as OutletLevel
Public propertyRunTimeDiagnostics
The getter is used to get a list of errors.
(Inherited from Structure.)
Public propertySideStructureBank
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).

(Inherited from Structure.)
Public propertySideStructureReservoir
Reservoir at end of side structure. Null if not side structure, or no reservoir is defined
(Inherited from Structure.)
Public propertyStartLevel
The water level at which the pump is activated.
Public propertyStartStopLevelControlActive
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 ControlModule, this will set this automatically (during Prepare)

Can not be combined with DischargeControlActive

Public propertyState
State of pump
Public propertyStopLevel
The water level at which the pump is de-activated
Public propertyStructureType
Type of structure
(Inherited from Structure.)
Public propertyTopoID
String used to identified cross sections
(Inherited from Structure.)
Public propertyTotalTimeActive
Total time the pump was active
Public propertyType
Structure type, unique for each structure.
(Overrides StructureType.)
Public propertyUpstreamWaterLevel
Upstream water level. Upstream refers to the direction of chainage. The water level is set by use of SetWaterLevels Unit: [m]
(Inherited from Structure.)
Public propertyUseMaximumDischarge
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.
Public propertyUseSuppressionFactor
If true, then suppresion factors from the PumpSuppressionFactorUpstream and PumpSuppressionFactorDownstream delegates are used to limit the available discharge of the pump. Default false.
