Compared with the power supply system at both ends, the multi-stage power supply is more stable, but the corresponding internal line structure is also more cumbersome. A hybrid mode control scheme is set up in order to deal with the deficiency of current DC voltage, which introduces skew characteristics, delays the power impact force in the process, effectively reduces the power change of multiple stations when the system starts, and finally establishes the simulation design in the PSCAD/EMTDC.
