Intellectual monitoring and planning system of energy efficiency indices of the traction power supply system

Abstract

The actuality of questions of energy saving in the traction power supply doesn’t give rise to doubts. At the same time in such complex composition as the traction power supply system, taking into account its cooperation with the electric rolling stock, questions solving of the energy efficiency increase must be accompanied by a complex efficiency assessment of the proposed activities. The technical and organizational arrangements implementing with this purpose in mind must not just secure the decline of the power intensity level of the vehicular process, but allow securing this vehicular process in the requisite volumes with excellent prospects at the moment and also be economically expedient. At present no such technologies and especially software tools exist which allow estimating and predicting the alteration of the energy efficiency indices of trains’ traction regarding the current values by change of the engineering parameters of the traction power supply system and the operating data of the railways’ areas. In this article a creation necessity of an intelligent monitoring system and an indices programming of the traction power supply system is justified, allowing determining the influence grade on the basic energy efficiency indices of the operational factors and the characteristics of the traction power supply system and to determine the optimal combination of these factors and characteristic for the justified changes planning of the traction power supply system characteristics and the improvement of the operational indices of trains’ traction in the view of the achievement of the maximal energy efficiency. The architecture of such a system is described. The tasks which solution allows practically realizing and implementing in maintenance the proposed elaborating are formed.

Structure and distribution of function between the stages of the information and measurement system for diagnostics of traction substations and contact network installations

“…The technical and economic criteria for the optimum information and measurement system (IMS) for the functional diagnostics of traction power units integrated with the existing operational control system can be evaluated in several ways [1][2][3] For example, the economic measure of IMS efficiency is the best value for money measure with maximum reliability [4,5].…”
