METHOD FOR MULTI-FAULT POWER RESTORATION OF POWER DISTRIBUTION NETWORK

摘要

The invention discloses a power restoration method for a power distribution network with multi-faults. The method overcomes the shortcomings that a traditional fault restoration method for the power distribution network can not solve multi-faults. The method comprises the steps of performing multi-fault judgment on multiple faults not completely processed, to form a plurality of multi-faults and a plurality of single-faults; then performing independent fault restoration area division on the multi-faults, and performing power restoration on independent fault restoration areas one by one; and after the multi-faults are processed, performing power restoration on each single-fault. According to the invention, the power restoration efficiency is greatly improved, thus contributing to the real-time performance of power 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 power restoration are more approximate after fault restoration, and therefore the power supply reliability of the power distribution network is improved.
