TModelHVDCLine

Package: PowerOperationsOpenAPIModels · Source: Operations/Branch/TModelHVDCLine.json

A High Voltage DC transmission line for modeling DC transmission networks.

This line must be connected to a DCBus on each end. It uses a T-Model of the line impedance. This is suitable for operational simulations with a multi-terminal DC network. This line has no independent per-component power base, so its power fields are always natural units. Impedance, voltage, and voltage-droop fields are natural units only: there is no conventional DC base voltage from which to per-unitize them.

Properties

Property	Type	Required	Unit	Description
id	integer	yes	—	Unique integer identifier for this component.
name	string	yes	—	Name of the component. Components of the same type (e.g., PowerLoad) must have unique names, but components of different types (e.g., PowerLoad and ACBus) can have the same name.
available	boolean	yes	—	Indicator of whether the component is connected and online (true) or disconnected, offline, or down (false). Unavailable components are excluded during simulations.
active_power_flow	number	yes	MW	Initial condition of active power flow on the line. Units: MW.
arc	integer	yes	—	An Arc defining this line from a bus to another bus.
base_current	number	yes	kA	Base current of the line as recorded by the source data. No field of this component is per-unit on it. Units: kA.
r	number	yes	ohm	Total series resistance, split equally on both sides of the shunt capacitance. Units: ohm.
l	number	yes	H	Total series inductance, split equally on both sides of the shunt capacitance. Units: H.
c	number	yes	F	Shunt capacitance. Units: F.
operational_flow_limit	OperationalFlowLimit	—	MW	Operator-set minimum and maximum flow in each direction. Absent means no operational limit. Units: MW.
