The invention discloses a reclosing and low-voltage ride-through combined fault power supply recovery method and system. The method comprises the steps of dividing each distributed power supply into at least one planning island region; detecting an active power distribution network circuit, performing fault positioning, and determining a fault generation segment; isolating the fault generation segment, and detecting whether a complete planning island region exists in each distributed power supply or not; judging whether voltage drop degree of a PCC position conforms to a low-voltage ride-through condition or not, if yes, maintaining gird-connected running of the distributed power supply, and providing reactive power support, otherwise, exiting; and selecting a corresponding fault power supply recovery method according to different fault conditions. The influence of reclosing on low-voltage ride-through of the distributed power supply is considered, a power supply recovery circuit is fully utilized, an intelligent power distribution terminal is used for communication and information interaction, different fault power supply schemes are implemented with regard to different fault conditions, and fault power supply recovery of the power distribution network is favorably and rapidly achieved.
