Traction Substation Transformer Power Distribution Investigation Under Asymmetric and Nonlinear Loading Conditions

Abstract

The article deals with the study of power distribution in the traction transformer that feeds the railway transport quarry network. The equivalent scheme of the traction transformer according to the deduced power balance equations is constructed. The analysis of power distribution calculation methods in the transformer is carried out. According to the known method of determining the power distribution in the traction transformer, based on the array of data taken from the traction substation transformer of the mining and processing plant, calculations of energy processes in the transformer. The energy indicators data of traction transformer primary and secondary windings are obtained. When analyzing the above results, it is noted that the power vector of the phases of the primary and secondary windings do not match, this may indicate a redistribution of power in the transformer.
