The Influences of Electrical Traction on Distribution System

This paper deals with the analysis of power quality influenced by the one of the biggest power consumers in the Slovak Republic – electrical traction. The adversely effects caused by electrical traction affect the distribution grid, from which the electrical traction is fed throughout the whole Slovak Republic and so they decrease the power quality in this grid. This problem is very actual in these days, because customers often use the electrical appliances that are sensitive to the shape of sinusoidal voltage wave. This paper analyses the results of the power quality measured in H-type substation, which is often used to supply the electrical traction. Some of these measured qualitative parameters were compared and evaluated according to the valid standard EN 50 160. The paper also focuses on the problematics of spreading current and voltage harmonics along the traction lines and to the higher voltage level. Therefore, the simulation model of a traction supply section was created in Matlab. At last, passive series LC filter was added to the created model, in order to eliminate harmonics caused by the traction vehicle.
