摘要： The invention relates to a backfeeding installation (30) which comprises: at least one stationary compressor (21) between a gas network (15) at a first pressure and a gas network (10) at a second pressure higher than the first pressure, and an automaton (33) for controlling the operation of each stationary compressor. The backfeeding installation also comprises: a distribution unit (31) for distributing gas from the gas network at the first pressure to each stationary compressor and to the gas inlet connector at the first pressure for at least one additional compressor (29, 45, 46); and a collection unit (32) for collecting gas from each station nary compressor and the gas outlet connector at the second pressure for each additional compressor. The automaton is configured to control the operation of each stationary compressor and of each additional compressor as a function of the compression capacity of the operational stationary and additional compressors.
