Application of analytical programming and imitation modeling for improving the power supply reliability of railway industry consumers

The practical application of the analytical program and the simulation model of electric power supply is considered, which is to determine the most reliable electric supply schemes. The results of the research make it possible: to predict the reliability indexes of electrical equipment; to establish "bottlenecks" in ensuring reliability; to develop measures to improve the efficiency of electrical equipment. The application of methods of simulation and analytical programming allows to take into account dependent failures, arbitrary laws of distribution of random variables and other factors influencing reliability. When creating a simulation, the following can be taken into account: the structure of the system under study and the possibility of modifying it; different modes of operation of the system and their characteristics; conditions imposed on the dependence of failures of elements. In the simulation model, arbitrary verification probabilities can be implemented reliably controlled elements and effects on the system. Therefore, the standards define imitation modeling as the most universal method for investigating the reliability of power supply systems.
