Area interchange is a required net export of power from, or net import of power to, a
specific area. This does not imply that the power is destined to be transferred to or from
any other specific area. To specify transfers between specific pairs of areas see
InterAreaTransfers.
In PSS/E, the basic transmission line model is an Equivalent Pi connected between network buses.

Network bus data record (in PSSE v30 format).
Network bus data record (in PSSE v33 format).
Case identification data.
Flexible AC Transmission System devices.
Each network bus at which fixed bus shunt is to be represented must be specified in at least
one fixed bus shunt data record. Multiple fixed bus shunts may be represented at a bus by
specifying more than one fixed bus shunt data record for the bus, each with a different shunt
identifier.
Each network bus to be represented as a generator or plant bus in PSS/E must be specified
in a generator data record. In particular, each bus specified in the bus data input with a
type code of two (2) or three (3) must have a generator data record entered for it.
Transformer impedance corrections are used to model a change of transformer impedance
as off-nominal turns ratio or phase shift angle is adjusted.
Using PSS/E, the user has the capability to identify in which area each
bus or
load resides.
Further, the user can schedule active power transfers between pairs of areas.
Each network bus at which a load is to be represented must be specified in at least one load
data record. If multiple loads are to be represented at a bus, they must be individually
identified in a load data record for the bus with a different load identifier.
Each load at a bus can be a mixture of loads with different characteristics.
Multi-section line group.
Each multi-terminal DC line record defines the number of converters, number of DC buses and
number of DC links as well as related bus numbers and control mode (see
DCLineID),
then data for:
Representation of a power network.
PSS/E allows the user to identify which organization or utility actually owns a facility,
a piece of equipment, or a load. Major network elements can have up to four different owners.
This facilitates interpretation of results and reporting of results on the basis of ownership.
Represents switched shunt devices, in the form of capacitors and/or reactors on a network bus.

Each AC transformer to be represented in PSS/E is introduced through transformer data records
that specify all the data required to model transformers in power flow calculations, with
one exception.
The two-terminal DC transmission line model is used to simulate either a point-to-point
system with rectifier and inverter separated by a bipolar or mono-polar transmission system
or a Back-to-Back system where the rectifier and inverter are physically located at the same
site and separated only by a short bus-bar.

Voltage source converter (VSC) DC lines.
All buses (AC and DC) and loads can be assigned to reside in a zone of the network.
To enable this facility, each zone should be assigned a name and number.
Specifically, the zone number is entered as part of the data records for the
buses and
loads.
The use of zones enables the user to develop reports and to check results on the basis of zones and,
consequently be highly specific when reporting and interpreting analytical results.
