Abstract: With the progress of power electronic devices in electric railway, harmonics in power systems become increasingly of concern.
This paper presents a case study on harmonics in a traction power supply system. The study was based on measurements realized in an electrical
drive station using a data acquisition system and a computer. It was analyzed the main power quality indicators: the power factor,
the reactive power factor, the deforming power factor and the total harmonic distortion of the current and voltage. The paper present also the simulation results of process of electric drive vehicles especially in railway using different passive LC filters using PSCAD-EMTDC simulation program.
Keywords: harmonics filtering, railway, power quality, PSCAD EMTDC simulation program

Abstract: In this paper, the authors intend to show how to apply the circuit description in parameter space
for a standard worst-case circuit analysis (WCCA). DC or AC or transient worst-case circuit analysis can be
performed only by testing the circuit for the vertices of a polytope in conjunction with a circuit simulator or
computational environment. In order to validate and show the effectiveness of this approach, DC and AC
worst-case circuit analyses of an analog electronic circuit performed in conjunction with a general-purpose
circuit simulator are presented and discussed.
Keywords: Worst-case circuit analysis, Analog electronic circuit, Polytope.
