Distributed Generation in Railroad Power Supply Systems

Application of regenerative braking on electric rolling stock

“…The main disadvantages of electric braking are the implementation of the braking effect only by the moving axles of the locomotives, the complication of electrical equipment and the control system for the operation of the power equipment of the electric rolling stock, and an increase in the heating temperature of the TEM windings [7]. Also, an obstacle to the use of recuperation energy in a larger volume can be malfunctions of electrical circuits, the presence of empty and lightweight cars in the head of the train (danger of squeezing out the cars) [11,14,15].…”

Modern methods for diagnosing electric circuits of electric trains

“…Various methods are used to diagnose the technical condition of locomotives, their systems, components, and assemblies [11,[18][19][20]. The variety of diagnostic methods is mainly due to two reasons: the complexity of the diagnostic systems, determined by the complexity of the structure of locomotives as an object of diagnostics, and the variety of technical diagnostics tasks arising from the requirements for the maintenance and repair of locomotives [21][22][23].…”

Diagnostics and reliability of current receivers

“…Reliability directly affects quality, efficiency, reliability, risk, availability, survivability. The technique can only be effective if it is reliable [18][19][20].…”
