Abstract:
A method for controlling at least two turbocompressors (1.1, 2.1), each having a control device (1.2, 2.2) for maintaining a distance relative to a surge limit curve (P1, P2) of the respective turbocompressor; wherein a first distance (A1.1, A2.1) is determined for each turbocompressor from its surge limit curve; wherein the distance to be maintained can be trimmed relative to this first distance in the control devices; and wherein the distance (A2.2) of a control device (2.2) to be maintained is trimmed relative to its first distance (A2.1) based on a trimming (A1.1→A1.2) of another control device (1.2) in such a way that a total process variable (dV/dt) remains substantially constant.
