Gas pipelines in Europe
The gas network is organized hierarchically and goes from the gas sources or producers via different pressure levels to the end consumer.
There are two subnetwork controllers in the gas solution which actively influence the pressure:
Device |
Terminal Configuration |
Regulator |
High in >> Low out |
Compressor |
Low In >> High Out |
This makes it possible to map the entire mode of operation from the source/production site to the end consumer. Higher-pressure transport pipelines (pressure up to 200 bar in some cases, e.g. Nord Stream) are used for transport over long distances. The pressure is always reduced (friction losses due to wall roughness, fittings and change of direction). The gas is then distributed more and more finely (pressure reduction) until it reaches the end consumer.
Different value ranges apply for the pressure designations (country-specific). For this reason, this circumstance was taken into account in the model and only the function of the line was used.
