| description | The invention provides an MCC type high voltage DC power transmission (HVDC) DC side power supply system, comprising two groups of HVDC modules which are connected to the two ends of a high voltage three phase wire; two capacitors C1 are connected in parallel between the two groups of HVDC modules; each group of the HVDC module comprises three link module strings; each group of the link module strings comprises two link modules which are connected in series; two inductors L are connected in series between the two links modules; a node is positioned between the two inductors L; the ends of the link modules which are not connected to the inductors L are connected together; and three nodes in each HVDC module are connected to the high voltage three phase wire in series. The MMC type high voltage DC power transmission (HVDC) DC side power supply system solves the problem that the MMC type HVDC is not easily designed and thus the unit is not easily powered because of the limitation on the price and the volume of the high resistance transformer in the process of realizing the N+2 redundancy operation of the module unit. |
