The utility model relates to a fault recovery control system of many feed -ins direct current transmission system, including controller, fault detector and a plurality of power modulation ware, the controller is communication connection fault detector and power modulation ware respectively, fault detector is located the circuit that the needs that receive the end alternating -current system detected the trouble, the power modulation ware is located the dispatch Center of HVDC subsystem, the event detector detects the trouble that receives the end alternating -current system, and output fault -signal extremely the controller, a plurality of power modulation signals of controller output to each power modulation ware. Having realized the monitoring to whole many feed -ins direct current transmission system, having improved the wholeness of fault recovery control, fault recovery is efficient.
