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.

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.
parameter_units	string (ImpedanceUnitBasis)	—	—	Unit basis for this line’s impedance field (r).
base_current	number	yes	A	Base current for per-unitization of this line’s per-unit fields — this DC line per-unitizes against a current base, not a power base. Units: A.
r	number	yes	ohm / pu (by parameter_units)	Total series resistance, split equally on both sides of the shunt capacitance. Units: per parameter_units — NATURAL_UNITS: ohm, COMPONENT_BASE: pu .
l	number	yes	pu	Total series inductance, split equally on both sides of the shunt capacitance. Per-unit on this line’s base_current. Units: pu.
c	number	yes	pu	Shunt capacitance. Per-unit on this line’s base_current. Units: pu.
active_power_limits_from	MinMax	yes	MW	Minimum and maximum active power flows to the FROM node. Units: MW.
active_power_limits_to	MinMax	yes	MW	Minimum and maximum active power flows to the TO node. Units: MW.
