- the electrodynamic machine here is preferably equipped with a continuous shaft, so that either the turbine is directly connected to the free end or preferably a torque-transmitting operational arrangement is coupled to a free end of the independent turbine shaft.
- This second shaft arrangement has particular advantages with regard to the use of standard modules and brings with it a suitable shaft dynamics.
- the rotor dynamics is of particular importance, because a unified shaft train of turbine, electrodynamic machine and compressor due to the length of the arrangement would have a particularly complex rotor dynamics, in particular with respect to the bending vibrations.

At the interfaces, standard volume flows U, V, W, X, Y, Z flow into the gas distribution network 1 of the territory 2 or out at respectively determined pressure levels.
- the pressure level can for example be between 50 and 100 bar.
- the gas distribution network 1 is a meshed network with several nodes 4. At various locations there are supplier withdrawals 5, at which gas of a certain individual pressure pl - plO is taken from the gas distribution network 1. At the same time it is possible that storage feeds into the grid take place.
- the pressure pl - plO can fluctuate within contractually defined limits, which are usually set between 50 and 100 bar.

- the task of the pipeline compressor station PCO which corresponds to the compressor installation COAN according to the invention, is to ensure the various standard volume flows and pressures at the supplier withdrawals 5.
- the withdrawals may fluctuate greatly, in particular as a function of the season, as well as the standard volume flows U, V, W, X, Y, Z at the interfaces 3 of the gas distribution network 1, so that operational situations which are difficult to predict for the pipeline compressor station PCO arise.
- both the pressures pl - plO and the standard volume flows U, V, W, X, Y, Z are subject to great fluctuations, for example fluctuations between 0 and 1,000,000 cubic meters / hour even when the conveying direction is reversed.
