Golub G. Methods of organization of computer systems for intellectualization of control procedures and optimization of power supply modes of railway transport

In the thesis work the methods of synthesis of distributed computer systems and network technologies for monitoring, identification, optimization and intellectualization of procedures for managing the energy saving modes of power supply systems for railways were further developed. Mathematical models of organization of monitoring, control and identification of parameters of traction electric networks of railroads and ways of organizing synchronously registered primary information and its formation as a single information space have been improved. For the first time, methods for the synthesis of architectures for microprocessor protection systems for traction networks with flexible logic and broad functional capabilities for recognizing abnormal and emergency modes of operation of power supply systems have been proposed, and on their basis a structural scheme of a microprocessor protection system for feeders of electric traction networks of railways has been developed. A differential mathematical model is proposed for determining the level of information security of nodes in the graph of a local computer network of a traction substation that is based on the theory of Pukhov differential transformations as the basis for creating intellectual means of protecting information resources of local computer networks. The ways of improving the architectural solutions of the computer system for controlling the modes of electric networks of railways have been developed and investigated, which makes it possible to improve the reliability and efficiency of the information and diagnostic functions of the system, providing a comprehensive automated control of the power supply modes, and is focused on solving the problems of technological, operational and dispatching control.
