The invention discloses a method, device and equipment of inter-tripping small power supplies for reclosing, and a storage medium. Whether an outlet line is directly connected with a small power supply is determined by searching for the small power supply line flag bit of the outlet line connected with a substation. If the outlet line is directly connected with a small power supply, there is onlythe need to disconnect the circuit breaker of the outlet line and send an updated small power supply inter-tripping instruction to an adjacent substation. If the outlet line is not directly connectedwith a small power supply, the circuit breaker of the outlet line does not need action. If the small power supply line flag bit of the outlet line of the adjacent substation is directly connected witha small power supply, the circuit breaker of the outlet line of the adjacent substation is disconnected. The line connection between the substation and the adjacent substation is intact, and the blackout scope is reduced. If we want to realize the function of inter-tripping small power supplies, we can only remove all lines connected with the substation and containing small power supplies. Amongall the lines, the lines connected to the substation but not containing small power supplies must be removed together, which will easily lead to a larger blackout scope. The technical problem is solved by using the technical scheme of the invention.
