Based on cross-regional power supply range search method and system cim model

The present invention discloses a range of inter-regional power supply system based on the search method and the CIM model. In this method, first create based on the size of the power supply grid where the hash function; according to the hash function, the identification numbers of all equipment in the power grid is mapped to a discrete hash table, using the chain address conflict resolution, discrete hash table forming a hash grid topology; topology using hashes of the power supply device specified search range. The present invention through the establishment of all device resources discrete hash table, the equipment in the power range of fast and accurate positioning, the calculation is greatly reduced, thereby improving the search efficiency power supply range.
