“…Through the modelling of the internal components of the converter, the equivalent high‐frequency model of the converter can be established. Then an accurate equivalent noise source model can be obtained, which is the basis of the research on the filter of the power carrier band [7–9]. Up to now, ± 800 kV UHVDC project has been put into operation and it can be a reference for the research of ± 1100 kV UHVDC project.…”

As the key equipment of Ultra High Voltage Direct Current (UHVDC) transmission system, converter valve would bear different forms of overvoltage. Consequently, a wideband model for ±1100kV UHVDC converter valve is essential for converter system to make overvoltage analysis, insulation design and electromagnetic disturbance prediction. This paper proposed a wideband modeling method for of ±1100kV converter valve. Firstly, the physics-based wideband model for key component in converter valve module is built, of which the parameters could be obtained through genetic algorithm. Secondly, the parasitic capacitances are obtained through simplified boundary element method according to the given structure of ±1100kV converter valve. By combining wideband models for key components in converter valve module and the parasitic capacitances of valve tower, the integrated wideband model (IWM) for converter valve could be obtained. The systematic modelling method proposed in this paper could also be of reference value to the modelling of other large-scale complex high voltage power electronic equipment. Finally, the experiments for converter valve module and converter tower are carried out, and the corresponding results justified the effectiveness and correctness of the proposed wideband model for converter valve tower.
