Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] The present invention provides a search method for cross-regional power supply range based on CIM model, such as figure 1 As shown, firstly, the power supply area is divided according to the voltage of the power supply, and the non-power supply high-voltage area is removed. Then construct a hash function, use the hash function to generate a discrete hash table of the power supply area, use the discrete hash table to perform a fast search, and highlight the searched power supply area. If the power supply scope involves multiple regions, the power supply networks of multiple regions are spliced ​​and displayed based on the Common Information Model (CIM for short) and Scalable Vector Graphics (SVG for short).

[0035] To this end, the cross-regional power supply range search method provided by the present invention includes the f...

Abstract

The invention discloses a method and a system for searching a cross-regional power supply range based on CIM model. The method comprises steps of establishing a hash function according to the size of the power grid where the power supply is positioned, mapping all identification numbers of all devices in the power grid to a discrete hash function table, using link addresses to solve conflicts, using the discrete hash table to form a hash topological graph of the power grid, and utilizing the hash topological graph to search the power supply range of the specific device. The invention can perform quick positioning on devices within a power supply range through establishing discrete hash tables on all device resources, the calculation quantity is greatly reduced and the searching efficiency of the power supply range is improved.

Description

technical field [0001] The invention relates to a power supply range search method, in particular to a power grid CIM model-based power supply range cross-region search method, and also relates to a search system for realizing the method, which belongs to the field of power grid dispatching automation. Background technique [0002] Among the currently commonly used power supply range search methods, network connectivity analysis and network topology analysis of network path search are the main methods. Among them, depth-first search and breadth-first search algorithms are usually used to search the power grid topology map. The depth-first search algorithm is a non-heuristic search that needs to traverse all the nodes of the topology tree, which is a blind search. The breadth-first search algorithm is also a blind search algorithm. Different from the depth-first algorithm, the breadth-first algorithm starts from the root node, traverses the nodes of the topology tree along ...
