Research of parameters of the traction network of electric locators of mining enterprises

Currently, digital terminals are installed in the power supply devices of railways electrified in direct running, subways and urban transport in Russia and in world practice for monitoring, protection and diagnostics of the railway network. The adjustment of the current settings based on the results of the analytical calculation does not ensure the reliable functioning of the feeder protection. In a number of publications, including the authors of this article, it is proposed to correct the results of analytical calculation using mathematical modeling, and then additionally with subsequent adjustment based on the results of monitoring the parameters of electric trains and traction network. In their mass, various protections reacted to such parameters as voltage, current, heating of current-carrying parts and others separately. The development of digital automation tools made it possible to create protection systems that integrally respond to the parameters of transient processes in the traction network. At the same time, multi-channel digital terminals (Inter) revealed difficulties in determining their coverage area and settings. As a result of the research carried out for the West Siberian Railway, a method was proposed for selecting the type of protections, their zones of action and settings, based on monitoring the operating modes of the traction network and mathematical modeling, which improved the parameters of the protection kit as a whole and increased its sensitivity.
