Abstract

The purpose of the publication is to develop a methodology for presenting the unit "6 kV compressor-synchronous electric motor" in the form of a finite state machine.
 It is hypothesized that the behavior of the compressor unit can be associated with the behavior of an abstract deterministic finite state machine.
 The theory of finite state machines and graphs is applied to analyze the operation of a compressor installation using the example of a compressor of a large-tonnage shop for the production of ammonia. It is shown that the theory of finite state machines allows combining all possible modes of operation and shutdown of compressor units. Coding of reasons for compressor shutdown due to problems in the electrical or mechanical parts of the compressor unit is proposed. A diagram of state transitions has been developed for it. Such a diagram can be useful for compiling a concise description and understanding of the operation of a compressor unit, advanced training of technological personnel during industrial training, for emergency training, etc. 
 A graphical analysis of the obtained diagram was carried out. The optimal (most perceived in terms of energy efficiency) route of the graph is determined.
 The proposed form of abbreviated recording of the compressor operation cycle and the electronic mileage log, which allows you to calculate the remaining resource of the compressor installation and the compressor operation time.
 The implemented methods make it possible to identify bottlenecks in the complex electrical and technological equipment of industrial enterprises.
