Power quality in the circuits of traction substation

Journal of Civil Engineering and Transport, 2023
Rail transport in Poland uses direct current electric traction to power vehicles (locomotives and multiple units). It is therefore necessary to convert the AC voltage of the power system into the DC voltage of the traction system. The conversion of alternating voltage into direct voltage takes place in traction substations. Rectifier units installed at
