[0080] Example: avoiding continuous operation in torsional resonance excited by a frequency converter of a compressor train ( Figure 1 to Figure 4 )
[0081] figure 1 (Schematically) shows a compressor installation 50 , for example for the liquefaction of natural gas, which has a compressor train 1 with a single-shaft turbo compressor 51 , simply referred to as compressor 51 .
[0082] A converter-controlled electric motor 2 is used in the compressor unit 1 (which drives the compressor unit 1 at a variable rotational speed 6 ) in order to be able to realize the operating speed range of the compressor installation 50 or compressor 51 (power range of the installation 50, see image 3 Compressor characteristic curve family 52).
[0083] In this case, the required performance (for example for the compressor 51 or the compressor assembly 1) in the compressor assembly 1 is changed or increased (cf. figure 2 , required for the power ramp 53) the rotational speed change 130 is ...
