Node Data Type
represents a single electrical node or bus in an electric power system. Essentially, the connection between every other single-terminal or two-terminal device is demarcated by a
object. A Node
has a one-to-one relationship with its VoltagePhasorGroup
has a Voltage
and each Voltage
has a measured Node
is also used to define the Base KV for itself and the terminal of any device connected to it.
are used to connect devices that belong to both Substation
objects. Therefore, a Node
can either be a child of a
(in which case it would have a non-zero value for the ParentSubstationID
) or a child of a
(in which case it would have a non-zero value for the
). A Node
can have a non-zero value for both of these properties if it is either the
or the ToNode
of a TransmissionLine
. These nodes are owned by both the
and the FromSubstation
, respectively. However, in the XML representation of the network, these
are still elements belonging to the Substation
. The only indication in the XML which indicates ownership by the associated
is this ParentTransmissionLineID
property and the
property of the TransmissionLine
. These properties are outlined in the following table:
|Node Property/Attribute Table
||A statistically unique identifier for the instance of the Node data type. Lazily instantiated.
||A non-zero, positive, integer, unique identifier for the instance of the Node data type.
||A non-zero, positive integer non-unique descriptor for the instance of the
Node data type.
||An uppercase, non-unique acronym descriptor for the instance of the Node data type.
||A non-unique name descriptor for the instance of the Node data type.
||A non-unique description for the instance of the Node data type.
||The InternalID of the VoltageLevel object which defines the base KV of the instance of the
Node data type.
||The InternalID of the parent Substation object of the instance of the
Node data type. If a Node does not belong to a Substation, this value can safely be set to zero.
||The InternalID of the parent TransmissionLine object of the instance of the
Node data type. If a Node does not belong to a TransmissionLine, this value can safely be set to zero. A node which electrically connects a terminal of a
TransmissionLine with the rest of the Substation will have a non-zero value for both the
ParentSubstationID and the ParentTransmissionLineID.
||The child data type which describes the measured and estimated values of the voltage of the electrical
Node. See Voltage Phasor Group Data Type Section.

Theres some code that should go here :P
