“…Passive filters for railway electrification systems must perform the following functions [3,4,9,10]: -reactive power compensation; -average pantograph voltage increase due to the suppression of powerful low-frequency harmonics; -damping of resonance phenomena in the traction network and the utility supply system. This paper investigates the harmonic resonance problems in railway electrification systems.…”

“…This filter includes series connected capacitor bank and a tuning reactor. In some cases, two-resonance filters are used to provide reactive power compensation and suppress the most powerful 3rd and 5th harmonics of the traction load current [10]. The disadvantage of single-tuned filters is that they suppress low-frequency harmonics but do not damp the resonance maxima of the frequency characteristics.…”

“…The simplest broadband passive filters of the 1-2 order for RES are considered in [2,3,12]. The analysis conducted in [9,10] showed that the use of broadband damping filters provides reducing the locomotive pantograph voltage total harmonic distortion, attenuate overvoltage due to the resonance mode damping and increase the average pantograph voltage value. Broadband filters are appropriate for randomly varying loads.…”

The purpose of the investigation is to analyze resonant modes in electric power systems that feed the traction load, to study the mutual influence of the traction network and the external power supply system. Simulation model of the power supply system with traction load, implemented with the Matlab/Simulink software package, is considered. The proposed model is used to study the influence of various parameters of the power supply system on resonant modes, including the length of lines, the short-circuit power of the external power supply system, and the spectral composition of locomotive currents. It is shown that the study of resonant modes should consider the traction power supply system and the external network as a single system. Its frequency characteristics depend on both the parameters of the traction network and the parameters of the external power supply system. The ways to improve technical characteristics of passive filtering systems (PFS) for traction railway networks due to the sustainable choice of passive filter configurations have been investigated. Different PFS that provide compensation for voltage distortions in both the traction and external network have been proposed. They provide the suppression of powerful low-frequency harmonics and the resonant mode damping in the traction network – transformer – external network system. Broadband filters of the 3-5 orders have been proposed to control the characteristics of the traction power supply system.
