Disclosed are a method for searching a cross-regional power supply area based on a common information model (CIM) and a system thereof. In the method, a hash function is first created according to a size of a power grid in which a power source is located; identification numbers of all devices in the power grid are mapped to a discrete hash table according to the hash function, and a collision is solved by using separate chaining; and a hash topological graph of the power grid is formed by using the discrete hash table; and a power supply area of a designated device is searched by using the hash topological graph. According to the present invention, devices in a power supply area are located rapidly and accurately by creating a discrete hash table for all device resources, so that the amount of computation is greatly reduced, and the efficiency of searching the power supply area is significantly improved.

The invention provides an automatic mapping method for a distribution network based on logical layout. The method includes: (1) pretreating a model of the distribution network model by analyzing it, and partitioning and striping the distribution network model to generate a plurality of partial models; (2) analyzing an automatic mapping algorithm to be utilized by comparing a distribution network graph obtained by the algorithm with the distribution network model; (3) achieving automatic layout of the partial models or the whole distribution network model on the basis of analysis of the automatic mapping algorithm to be utilized; and (4) analyzing and treating the automatic layout to achieve the generation of the distribution network graph with a desired practical effect.
