Problems solved by technology

[0003] In the partition function of the power grid dispatching system, the dispatcher needs to quickly obtain the partition to which the equipment belongs, but when the connection mode of the power grid dispatching system changes and causes the partition to merge or disassemble, the information cannot be intuitively obtained from the existing power grid dispatching system. The current practice It is still based on manual judgment, the work is cumbersome and it is difficult to ensure the accuracy of information
[0004] This not only limits the actual effect and technical development of the technical support system operation, but also has a certain gap in meeting the needs of the further development of the power grid, reducing the intelligence, advancement, safety and reliability of the smart grid.

Abstract

An automatic intelligent power grid partitioning method includes establishing a power grid model; abstracting the power grid into a data structure composed of vertex sets and edge sets; defining partition boundary information according to a topological structure of the power grid; after judging that the changes occur to the topological connection of the power grid, performing the topological search to the power grid model to acquire the partition information; displaying the partition information on display equipment. According to the arrangement, the partition information of equipment in the power grid is rapidly identified, partition combination and splitting is instantly founded, and topological computations are fewer at the premise that instantaneity is guaranteed.

Description

technical field [0001] The invention relates to a grid automation intelligent partitioning method. Background technique [0002] The power grid dispatching system has been in operation for many years and is relatively mature and stable. However, with the gradual expansion of the grid scale, some basic functions have gradually increased the difficulty of maintenance and monitoring. [0003] In the partition function of the power grid dispatching system, the dispatcher needs to quickly obtain the partition to which the equipment belongs, but when the connection mode of the power grid dispatching system changes and causes the partition to merge or disassemble, the information cannot be intuitively obtained from the existing power grid dispatching system. The current practice It is still based on manual judgment, the work is cumbersome and it is difficult to ensure the accuracy of the information. [0004] This not only limits the actual effect and technological development of ...
