Application of a generalized graphical-analytical model in building a semi-Markov model of the monitoring and control subsystem of the subway power supply system
Improving the efficiency of the monitoring and control subsystems of the electric power industry is due to the introduction of intelligent technologies within the framework of new concepts. When carrying out work on the modernization of power supply facilities, an important stage is the preparation of a qualitative analysis of the processes of functioning and restoration of the facility. The article presents a semi-Markov model that allows you to analyze the object of modernization, as well as present options for the relationship of the parameters of the object with the prospect of expanding functionality by regulating the structure and the parameters themselves. The constructed semi-Markov model of the monitoring and control subsystem of the subway power supply system based on graph theory and using the method of generating functions makes it possible to present the interconnections of the states of the power supply system and determine the ratios that are important for substantiating the assessment of the degree of achievement of the requirements for the probability of recovery, recovery time and the required amount of funds diagnosis.
