摘要（英）：

The invention relates to a parameter design method of a modular multilevel converter (MMC) valve steady-state operation testing device auxiliary valve capacitor. The method includes the following steps that (A) charging energy of an auxiliary valve in one power frequency cycle is confirmed; (B) the charging energy of the auxiliary valve under a given capacitor direct voltage fluctuation rate is confirmed; (C) a capacitance value of the capacitor in the capacitor direct voltage fluctuation range is confirmed; (D) a nominal voltage of the capacitor is confirmed; and (E) a rated current of the capacitor is confirmed. The parameter design method can be used for the design method of the capacitance value, the nominal voltage and the rated current of the MMC valve steady-state operation testing device auxiliary valve capacitor. Economical and reasonable capacitor parameters can be given through the parameter design method of the MMC valve steady-state operation testing device auxiliary valve capacitor.
