USE OF THE THEORY OF FINITE AUTOMATA FOR SUPERVISION OF THE OPERATION OF THE COMPRESSOR UNIT

The purpose of the publication is to develop a methodology for presenting switchgear cabinets with a voltage of 6 (10) kV in the form of a state machine. The complete distribution device is one of the most responsible electrical devices of medium voltage. Their reliable operation ensures uninterrupted power supply to industry, administrative and household premises, and agriculture. It has been proven that the principle of operation of switchgear cabinets is similar to a deterministic finite state machine. The theory of finite automata and graphs is applied for the analysis of the operation of the cabinet of a complete switchgear. It is shown that the theory of finite state machines allows combining all possible modes of operation of switchgear cabinets. Representation of the switchgear cabinet model in the form of a deterministic finite state machine allows designing a cabinet with the necessary features. A 6 (10) kV switch cabinet state transition diagram has been developed. Such a diagram can be useful for understanding the operation of the cabinet of a complete switchgear, improving the qualifications of electrical personnel. A complete description of the operation of the cabinet using morphological phrases is given on the example of the K-XII type switchgear cabinet with the VMP-10K circuit breaker (SD-300 kW connection). It was concluded that any switching device with a voltage up to and above 1000 V can be represented as a finite state machine. In addition to the diagram of state transitions, the operation of switching devices should be explained using morphological phrases (IF, AND, OR, THEN, NOT POSSIBLE).
