Introduction
This document is part of the grid modelling approach and details the grid model data requirements for data supplied by Dutch transmission and distribution system operators and describes in detail the Containment of Equipment .
Most of the terms in this document are used within the energy industry, particularly in standards like the IEC Common Information Model (CIM).
CIM has an Equipment Container class that provides a means of grouping pieces of Equipment together to represent both electrical and non-electrical containment.
Core entities
Subclasses of cim:EquipmentContainer include:
Modelling choices
Substation Containment
Within Substations there is a containment hierarchy for the subclasses of EquipmentContainer
-
A Bay can contain cim:Equipment
-
A VoltageLevel can contain Equipment and Bays
-
A Substation can contain Equipment, VoltageLevels and Bays
Line Containment
Lines are also subclasses of EquipmentContainer and can contain equipment, but they are not contained by any other EquipmentContainer. The Equipment in the Line are connected to the network graph via Terminals, but they do not have a containment relationship with any other EquipmentContainer.
Geographical Containment
Substations and Lines are contained by cim:SubGeographicalRegion (TSO/DSO service area). Which in turn are within a cim:GeographicalRegion (Country). This is important for geographical containment and for the use of geospatial coordinates (latitude and longitude) for the equipment contained within the Substation.
