“…The impedance method [27] describes the power supply and load of the system in the form of output and input impedance, the closed-loop gain and stability of the system can be judged by the equivalent impedance ratio of the power supply subsystem and the load subsystem. The above two subsystems establish impedance models according to their respective control structures and parameter characteristics, and are independent of each other.…”

The traditional 25KV electric railways have various problems such as power quality issues, passing neutral sections, complex storage, and utilization of regenerative braking energy, the medium‐voltage direct current (MVDC) traction power supply system (TPSS) may be a potential alternative electric railway mode and can be freely accessed to the renewable energy and energy storage systems, which is an important development direction of the future low‐carbon RES. This paper first describes the structure and characteristics of the current Railway Electrification System (RES), and then analyzes and summarizes the current research status of the MVDC TPSS topology structure, modeling method, stability criterion, and analysis method and coordination control strategy. Finally, combined with the research status, the development direction of the MVDC TPSS has prospected. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

“…Several studies analyse the parallel and series resonances of the equivalent impedance at the traction system pantograph terminals, [8], [9], [15], [17], [18], [19], [20]. Knowledge of the harmonic impedance of catenary line is important for designing effective harmonic resonance mitigation measures.…”

“…These Gate Turn-Off (GTO) or Insulated-Gate Bipolar Transistors (IGBT) based converters (single H-bridges, interleaved bridges or multilevel converters) operate under some kind of pulsewidth modulation (PWM) method. Usually, they are current-controlled converters and inject into the highvoltage catenary harmonics of different frequencies, magnitudes and time varying, [6], [7], [8], [9], [10]. These harmonics circulate in the catenary line and may originate network resonances.…”

The power supply architecture of most AC electric railway vehicles is constituted by transformers and catenaries at increasingly high power levels. Inside the vehicles, the interface between the catenary and the DC-bus of the traction motors is based on a transformer and power electronics converters. A large part of these are AC-DC four quadrant converters that operate in parallel at relatively small switching frequencies. However, the use of the interleaving principle allows reaching a low harmonic distortion of the catenary current and imposing specific harmonic ranges in this current. Nevertheless, the current is not a pure sinusoidal wave and its harmonics can excite unwanted resonances due to the combined effect of the catenary distributed parameters, the substation equivalent impedance and the current frequency spectrum. This paper analyses this phenomenon and proposes a control strategy capable of minimizing the resonance effects in two different power supply architectures.
