The invention discloses an in-disaster power distribution network communication network optimization recovery method based on mobile self-organization. The method comprises the following steps: S1, obtaining multivariate data in a power distribution network; S2, determining the communication network state of the distribution network in the disaster by using a grid method; S3, judging whether the power distribution network communication system needs transient recovery or not, and determining a repair mode of the power distribution network communication system according to a judgment result; S4,based on the characteristics of the mobile self-organizing network, researching an optimization repair scheme of the power distribution network communication network; And S5, finding out a feasible scheme set under the target by utilizing a path search algorithm of network simplification and depth-first traversal, solving each feasible scheme, and selecting an optimal result as a final repair scheme. According to the invention, through integration processing of multivariate information in the power distribution network when a disaster occurs, the state of the communication system of the powerdistribution network in the disaster is rapidly determined, the optimal recovery scheme under the corresponding mode is found out, and the first-aid repair time of the communication network of the power distribution network is shortened to the maximum extent.
