Equipment Identifiers

he equipment identifiers included in the published static ratings information are those used in the AEMO ESCA SCADA system. They are as follows.

Site Name / Site ID

The Substation, Terminal Station, or Power Station name.

Plant Type / Equipment Type

Transmission Lines may be Line, Tie, Summ for summated lines, or S_REACT for series reactors. Transformers may be Trans, Tx, or Tf.

Plant ID / Equipment ID The equipment identifier.
Region The NEM region.
Measurement All values included in the publication process are MVA quantities.
Level NORM, EMER, or LDSH as described in section 3 below.
Alternate Value An identifier which describes when the rating is applicable, such as summer, winter, etc. Alternate Value application rules at the time of publication of this document are described in section 3 below. Note that any rating with an associated Alternate Value suffix of '_DYN' has a real time telemetered rating supplied by the asset owner. This telemetered value would normally be the rating applied in real time processes. If telemetered data is available, any associated static ratings will be used for predispatch, and for dispatch only on telemetered data failure.
Low and High The low and high provide a directional feature in the application of the rating. When associated with the Site Name, the Low and High are interpreted using the convention of :
A positive value is power flow from the Site into the equipment.

The following identifiers are only used the TER Daily report:

Rating The rating value. Positive values indicate power flow from the site into the equipment.
Rating Type Either STATIC or DYNAMIC. Ratings with the Rating Type of DYNAMIC have a real time telemetered rating value supplied by the asset owner. This report does not include the telemetered rating value in the Rating field. The dynamic rating value would normally be the rating applied in Dispatch (and in some cases for a number of Pre-dispatch intervals).
SPD ID The identifier used in a constraint equation RHS to reference the rating value
Effective From The date and time the rating is active from and available as an input to constraint equations
Effective To The date and time the rating is made inactive and unavailable as an input to constraint equations
