Objects and Methods
Inline Power Plant
This object models an inline power plant, otherwise known as a run-of-the-river power plant. These power facilities rely on the natural slope of the river channel to provide necessary head. The object assumes there is little or no storage.
General Slots
Bypass
Type: Series Slot
Units: flow
Description: Flow diverted around the power plant
Information: Set to the sum of Min Bypass and any excess water that the turbines cannot pass. If Turbine Release is known, is set to (or Outflow) minus Turbine Release.
I/O: Output
Links: Not linkable
Inflow
Type: Series Slot
Units: FLOW
Description: Flow into the power plant
Information:
I/O: Input or Output
Links: May be linked to the Outflow of another object.
Max Turbine Release
Type: Table Slot
Units: flow
Description: Maximum flow which can pass through the turbines.
Information: A single value must be input.
I/O: Required input
Links: Not linkable
Min Bypass
Type: Series Slot
Units: flow
Description: Flow intentionally diverted around the power plant.
Information: Assumed to be zero in Bypass calculation if not user input.
I/O: Input
Links: Not linkable
Outflow
Type: Series Slot
Units: flow
Description: Flow rate below the power plant
Information: Set to the sum of Turbine Release and Bypass.
I/O: Input or Output
Links: May be linked to the Inflow of another object.
Power Plant Cap Fraction
Type: Series Slot
Units: None
Description: Fraction of the capacity at which the plant is operating.
Information: Used when the plant is not operating at full capacity (for example, a turbine in not functional)
I/O: Optional, the slot defaults to 1 if not input by the user.
Links: Not linkable
Turbine Release
Type: Series Slot
Units: flow
Description: Flow passing through the turbines.
Information: This value is used in power calculations.
I/O: Input or Output
