Zelezniak A. Methods of distributed computer monitoring systems organization and identification of electric networks modes of the railways

In dissertational work new methods and hardware-software means of the organization of the distributed computer monitoring systems and identification of electric networks modes of the railways are developed and investigated. On the basis of the spent analysis of modern and perspective computer technologies conceptual bases of corporate computer systems organization are developed, set of principles of the organization is formulated and the synthesis methodology is offered. A number of concrete architectural realizations of the distributed computer electric networks monitoring systems and the powerful electric objects, registration of the primary information based on the microprocessor environment with uniform common-system positions due to what, level of reliability and efficiency of traction networks functioning, and as consequence essentially increases is offered, traffic safety improves. For management of technological processes of electric objects methods functioning of the high-speed controllers organization focused on modern integrated technologies in the form of the large integrated schemes on the basis of programmed logic matrixes are offered. The methods of their diagnosing considering features of their manufacturing in integrated execution are resulted. For registration of the primary information and its intellectual processing at level of traction substations methods of continuous control computer systems synthesis and electric networks diagnostics at level of traction substations which provide from uniform information positions registration pre-emergency, emergency and post-emergency modes synchronously with work of system of protection are offered. Mathematical models and methods for identification of traction networks supernumerary modes, definitions of distance to a place of short circuit and carrying out of the analysis of emergency operation are developed and offered. On the basis of the spent researches the corporate computer system of monitoring and intellectual processing of railways electric networks primary information has been developed and introduced, results of experimental researches are resulted.
