The invention relates to a non-fault segment power supply recovery method based on an information platform. The method includes 1, transfer path supply searching, namely searching for all reasonable transfer supply paths by the topology analysis method; 2, capacity transferring, namely combing with the results of topology analysis and power flow calculation, analyzing the transferring capacity of the transfer supply paths and transferring load capacity, and implementing transfer supply, and allocating, namely opening a gate for outage and closing a gate for power supply from the power supply of the farthest end of a maintenance switch. Allocated transfer supply or independent transfer supply is determined according to the load situation of power supplies, and the power supplies are prevented from loading excessively due to transfer supply; low-load power supplies are adopted preferably, load is reduced according to power guaranteeing and power consumption information when residual power supply is insufficient, and the reduced load number and the load number are guaranteed being a balanced and ideal combination.
