The mathematical model and a block diagram of a synchronous motor compressor unit with a system of automatic control of the excitation

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