Analysis of railway transport snow-blowing equipment operating modes by diesel generator operation parameters

Abstract

Ensuring the transportation process in the Siberian region during the winter months involves protecting the railway infrastructure from external climatic factors, such as snow drifts and icing. To ensure timely clearing of tracks, a wide fleet of snow removal equipment on rails is used, the most numerous of which is the snow removal train type SM-2 and its modifications. The technological cycle of such trains can be reduced to three operations: clearing the track and loading snow mass, transportation to the unloading dead end, unloading and returning to the work site. Reducing both fuel and time resources in each technological link is an urgent task for railways. The purpose of the study is to evaluate the capabilities of monitoring the parameters of a diesel generator for more effective planning of operating modes of snow removal equipment. The current strength of three phases of a diesel generator was measured in various operating modes. The values of the current strength when starting electric drives of various train powers are estimated. The duration of operation of a diesel generator in nominal mode is compared with the operational need to set the operating mode in the technological cycle of clearing tracks from snow.
