The general requirements for the automatic excitation control system of synchronous motors of a compressor unit are shown, taking into account its operating modes. A mathematical model is presented, a block diagram of the excitation circuits of a synchronous motor of a compressor unit and an exciter, which characterizes the feedback of the internal properties of this part of the system in dynamics. A block diagram of a closed-loop automatic excitation control system is obtained, taking into account the elasticity of the mechanical part and a hard blow in the compressor gas pipeline. The obtained structural diagrams make it possible to determine the transfer functions of the considered system in terms of control and disturbing influences, the characteristic equation, as well as the dependencies of various frequency characteristics, which make it possible to investigate the dynamic indicators (stability, control quality, etc.) of the system.
