    Analysis of power losses in the main equipment static varcompensators taking into account the non-sinusoidalvoltages and ways of its reduction

    With the purpose of providing capacity on the West-Siberian railway, in recent times, adjustable reactive power compensation devices have been introduced. The schematic construction and parameters of such devices on the market are significantly different. In connection with this, it is necessary to choose from the set of schemes the most effective, corresponding to specific technical and economic conditions. The article assesses the power losses in the main equipment of two devices from different manufacturers, namely static thyristor compensators of reactive power produced by "KER Holding" Kazan and "Aidis groups" Moscow, installed on the Alambay and Novaya Dubrava sectional posts of the West Siberian Iron roads. The power losses in the equipment are calculated taking into account additional losses from the influence of higher harmonic components. The analysis of the circuit design of both devices in terms of loss reduction is carried out. Dependences of power losses in their elements on the generated reactive power and the current of the thyristor-reactor group are constructed. Probabilistic functions of the distribution of the current of the titrator-reactor groups of devices are given at preset settings. The results of measurements of power consumption of devices for own needs are presented. The effect of reducing power losses in the traction network from switching devices with losses in their main equipment is compared. On the basis of the work done, the elements with the greatest losses are identified. The features of each device, affecting the power loss in the main equipment, are described. Conclusions are drawn about the effectiveness of the schemes under consideration. Methods for reducing power losses in basic equipment and consumption for energy consumption are proposed.

    Traction possibilities of a double-locomotive powersupply 2ev120 when following on the limiting rises of the central siberian railway

    The article discusses the traction parameters of a new generation electric locomotive. The existing schemes of service areas by electric locomotives and locomotive brigades on the studied railway test site are presented. A comparison is made of the main parameters of DC and single-phase AC electric locomotives, the operation of which is currently organized on sections of movement with trains of calculated mass in the long-term mode of thrust on the climbs of various steepness. The scheme of the proposed organization of operation of a double power locomotive and locomotive crews is presented. Calculated traction parameters of a two-system electric locomotive, taking into account the plan and profile of the track in the proposed areas of operation, specific resistivity to the movement of the locomotive and the composition of the train at the estimated speed, specific accelerating and decelerating forces of the train. When two-system electric locomotives are put into operation, it will be possible to reduce the fleet of locomotives in operation, the number of traction arms due to their lengthening and the number of locomotive change points, reduce the transit time of freight trains, increase technical and local speed, average daily mileage and average daily performance of the locomotive, reduce power consumption per traction . The operation of such electric locomotives contributes to the development of polygon technologies for managing the transportation process, improving the quantitative and qualitative indicators of various railway enterprises.

    About the integrated approach to the analysis and control the energy efficiency of the structural subdivisions of railway transport

    In the article the questions of increase of efficiency of structural subdivisions, members of the directorates of the West Siberian railway - branch of JSC "Russian Railways", such as infrastructure Directorate, Directorate railcar rolling stock and the Directorate of buildings and structures. The aim of this work is to identify structural units with the lowest energy efficiency indicators. This requires estimation of an indicator such as relative energy efficiency over a period of time equal to one calendar year, based on data of annual consumption of electric energy and annual volume of enterprise work. The article also outlines the main provisions of the concept analysis and monitoring the energy efficiency indicators of stationary objects of the railway transport, which will identify inefficient structural subdivisions with the use of control actions to reduce irrational consumption of energy resources. Calculation of the relative energy efficiency is one of the stages of this concept. The result is a received charts of the relative energy efficiency of structural subdivisions of the West Siberian railway which allows to make a comparison of this indicator. According to the results of comparison found that 10 of the 65 structural units have a low indicator of relative energy efficiency. This suggests the need for careful study the reasons of the low values of energy efficiency in these structural subdivisions and proposals the measures to eliminate this situation. The method and sequence of these activities proposes into the third and fourth stages of the concept. The establishment and subsequent application of a unified approach to the analysis and monitoring of energy efficiency indicators for all departments will increase the energy efficiency of the territorial branches of JSC "Russian Railways" and the holding company as whole.
