A multi-faults service restoration method for a power distribution network overcomes the defect that a traditional service restoration method for the power distribution network cannot solve multi-faults. The method includes the steps of performing multi-faults judgment on multi-faults with processing unfinished, to form many multi-faults and many single-faults; then performing unaided fault recovery area division on the multi-faults, and performing power restoration on unaided fault recovery areas one by one; and after the multi-faults are processed, performing power restoration on each single-fault. By adopting the method, the service restoration efficiency is greatly improved, thus contributing to the real-time of service restoration; the factor of load balance is considered when common power restoration lines are decoupled, so that the load rates of the power restoration lines participating in service restoration are more similar after service restoration, and therefore the power supply reliability of the power distribution network is improved.
