Initial Event
pumping station is damaged and water flow out
Hello, fault reporting center … the power is not available, and the water is also cut off
spread of water causes the failure of power 3
due the power failure,networks the pumps won‘t work Becker, T. - Integrated 3Dto modeling of multi-utility

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!

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 Graph structure FeatureGraph

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 Network GAS
subNetwork >84 bar
subNetwork 71 – 84 bar
subNetwork 40- 71 bar
subNetwork 17 – 40 bar
subNetwork < 17 bar

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)
