1. Backfeeding installation comprising:
at least one compressor for compressing gas from a network;
an automaton for controlling the operation of at least one compressor;
a remote communication means for receiving at least one instantaneous pressure value captured remotely upstream or downstream of the backfeeding installation;
a means for predicting the change in pressure in the network upstream of the backfeeding installation, as a function, at least, of the pressure values received;
a means for determining a pressure threshold value for stopping and/or a pressure threshold value for starting at least one compressor as a function of the predicted pressure change,
the automaton controlling the stopping or operation of at least one compressor when the pressure at the inlet of each compressor is respectively lower, or higher, than the pressure threshold value that was determined, and
wherein the prediction means uses historic data of pressures observed at different points in the distribution network and of the starting and stoppinq of safety, expansion, backfeeding, consumption, injection functions.
