Components of Networks (excerpt)
power plant,
transmission
station
switch box, fuse
Pumps, Valves …
Streetlight,
switch gear
cabinet …
Pipe, T-pipe,
cable …
Each of these entities is
part of the utility network
and essential for the
supply task.
All of these entities have:
• different 3D
representations
• different semantics and
functions within the utility
network
BUT:
From a topological,
functional point of view
they are only a part of a
network!

Understanding Utility Networks

All Networks are aggregations of atomic entities such as pipes, stations,
cables etc.!

Representation of Network Entities
►
parallel to its 3D topographic representation a network
entity has functional and topological aspects
►
Networks are typically represented as graph structures,
and entities are separated either in line-like or point-like
shapes (cf. INSPIRE, ESRI, etc.)
►
we understand a NetworkFeature as a sub graph of the
whole network graph

Hierarchies: Internal Network Hierarchies
e.g. Gas network is an aggregation of sub networks of same commodity, but different
pressure systems and each sub network is an aggregation of Network entities
Distribution of gas goes from high pressure to low
pressure

Intermediate Summary
► Core
model for the representation of utility networks
● 3D topographic modelling
● functional modelling (includes 3D topological modelling)
● Support of hierarchies: complex objects, network hierarchies
● Provides homogenized and integrated view on multi-utility networks
► The
core model is independent of the specific type of
utility / commodity
► Next
steps
● generic modeling of Network Features according to their function,
e.g. distribution elements, devices, etc.
● generic modeling of Network Types (to comprise the multiple
different commidity types)
