| Base Voltage |
Defines a system base voltage which is referenced. |
| Breaker |
A mechanical switching device capable of making, carrying, and breaking currents under normal circuit conditions and also making, carrying for a specified time, and breaking currents under specified abnormal circuit conditions example: those of short circuit. |
| Busbar Set |
A collection of electrical busbars representing a set of interconnected conductors used to distribute power within a substation or electrical system, allowing for detailed modeling and analysis of power flows within a system. |
| Conducting Equipment |
The parts of the AC power system that are designed to carry current or that are conductively connected through terminals. |
| Connectivity Node |
Connectivity nodes are points where terminals of AC conducting equipment are connected together with zero impedance. |
| Coordinate Reference System (CRS) |
A Uniform Resource Name (URN) for the coordinate reference system (crs) used to define ‘Location.PositionPoints’. An example would be the European Petroleum Survey Group (EPSG) code for a coordinate reference system, defined in URN under the Open Geospatial Consortium (OGC) namespace as: urn:ogc:def:uom:EPSG::XXXX, where XXXX is an EPSG code (a full list of codes can be found at the EPSG Registry web site http://www.epsg-registry.org/). To define the coordinate system as being WGS84 (latitude, longitude) using an EPSG OGC, this attribute would be urn:ogc:def:uom:EPSG::4236. A profile should limit this code to a set of allowed URNs agreed to by all sending and receiving parties. |
| Equipment Container |
A modelling construct to provide a root class for containing equipment. |
| Feeder |
A collection of equipment for organizational purposes, used for grouping distribution resources. The organization a feeder does not necessarily reflect connectivity or current operation state. |
| Instance Set |
Instance of a version of a model part. This corresponds to a payload of instance data. |
| Location |
The place, scene, or point of something where someone or something has been, is, and/or will be at a given moment in time. It can be defined with one or more position points (coordinates) in a given coordinate system. |
| Position Point |
Set of spatial coordinates that determine a point, defined in the coordinate system specified in ‘Location.CoordinateSystem’. Use a single position point instance to describe a point-oriented location. Use a sequence of position points to describe a line-oriented object (physical location of non-point-oriented objects like cables or lines), or area of an object (like a substation or a geographical zone - in this case, have first and last position point with the same values). |
| Power Transformer |
An electrical device consisting of two or more coupled windings, with or without a magnetic core, for introducing mutual coupling between electric circuits. Transformers can be used to control voltage and phase shift (active power flow). A power transformer may be composed of separate transformer tanks that need not be identical. A power transformer can be modelled with or without tanks and is intended for use in both balanced and unbalanced representations. A power transformer typically has two terminals, but may have one (grounding), three or more terminals. The inherited association ConductingEquipment.BaseVoltage should not be used. The association from TransformerEnd to BaseVoltage should be used instead. |
| Substation |
A collection of equipment for purposes other than generation or utilization, through which electric energy in bulk is passed for the purposes of switching or modifying its characteristics. |
| Switch |
A generic device designed to close, or open, or both, one or more electric circuits. All switches are two terminal devices including grounding switches. The ACDCTerminal.connected at the two sides of the switch shall not be considered for assessing switch connectivity, example: only Switch.open, .normalOpen and .locked are relevant. |
| Switch Phase |
Single phase of a multi-phase switch when its attributes might be different per phase. |
| Terminal |
An AC electrical connection point to a piece of conducting equipment. Terminals are connected at physical connection points called connectivity nodes. |
| Transformer End Info |
Transformer end data. |
| Transformer Tank |
An assembly of two or more coupled windings that transform electrical power between voltage levels. These windings are bound on a common core and placed in the same tank. Transformer tank can be used to model both single-phase and 3-phase transformers. |
| Transformer Tank End |
Transformer tank end represents an individual winding for unbalanced models or for transformer tanks connected into a bank (and bank is modelled with the PowerTransformer). |
| Transformer Tank Info |
Set of transformer tank data, from an equipment library. |
| Voltage Level |
A collection of equipment at one common system voltage forming a switchgear. The equipment typically consists of breakers, busbars, instrumentation, control, regulation and protection devices as well as assemblies of all these. |
