IET Electrical Systems in Transportation, 2022 The railway traction loads produce massive harmonics that are injected directly into the traction power system. This causes serious waveform distortion in the supply voltage and even invokes a harmonic parallel resonance, which may lead to significant ...

A system-level harmonic mitigation method for HVDC systems – A practical case study
International Journal of Electrical Power & Energy SystemsIn recent years, non-characteristic harmonic resonance was observed in several high-voltage direct current (HVDC) systems in China. Intuitively, additional filters can be installed to mitigate the resonance.
