METHOD FOR THE UNINTERRUPTED OPERATION OF A GAS LIQUEFACTION SYSTEM

摘要

The invention relates to a method for the uninterrupted operation of a gas liquefaction system (1), wherein the operation is continuously monitored for at least those users of the refrigerant compressor component (4) which represent a two-digit percentage of the total load on the refrigerant compressor component (4). A total instantaneously available negative load reserve is calculated, and at least one predetermined turbine (10) is switched off when the load reserve reachable via a frequency regulation of the one or more refrigerant compressors (7) is lower than the energy demand of the largest of the refrigerant compressors (7) and either a refrigerant compressor (7) fails or a speed of frequency change (df/dt) for the power supply network for the gas liquefaction system (1) exceeds a preset threshold (121).
