Gas supply apparatus and associated method of operation for a gas turbine

The method involves providing an adjustable compressor (3) in a pipeline (2). A load is arranged downstream to the compressor and attached to the pipeline. The compressor is regulated depending upon the comparison of a compressor discharge reference pressure with a compressor discharge actual pressure, where the reference pressure is determined in dependence of load inflow reference pressure. An independent claim is also included for a gas supply equipment with a pipeline.
