“…This difference originates from the fact that the rectifier and inverter in the BTB HVDC system are strongly coupled to each other. Therefore, because DC harmonics calculation and the smoothing reactor design are incorrect in the classical method [2], the coupling influences between the rectifier and inverter have to be considered to calculate more detailed results.…”

This paper deals with a new concept for calculating DC harmonic voltages and currents of linecommutated HVDC systems. In contrast to the conventional method, this method is useful for BTB (Back-To-Back) HVDC systems without smoothing reactors or PTP (Point-To-Point) with very short transmission line. This method proposes a new direction for HVDC system design and analysis.The proposed method is applied to a 50 Hz/60 Hz BTB test system and a synchronized BTB test system. After simulation and verification, the new results are introduced. Keywords HVDC, BTB (Back-To-Back), PTP (Point-To-Point)
