Problems solved by technology
However, this treatment cannot solve the problem of differences in dispatching procedures in different regions, and cannot be widely promoted. Moreover, the accuracy of the rule base formed in this way is restricted by the accuracy of programmers' understanding. When the dispatching procedures are revised, the rule base cannot timely correction

Embodiment Construction
[0059] A method for establishing a power grid switching operation rule base based on rule mining, comprising the following steps in sequence:
[0060] Establish a power network state model;
[0061] Data preprocessing of historical operation order tickets;
[0062] Use ant colony algorithm to search;
[0063] Regular pruning.
[0064] Such as figure 1 As shown, the establishment of the power network state model includes the following steps:
[0065] S11: Establish a network topology model consistent with the actual structure of the primary equipment of the power grid, use busbars, circuit breakers, and transformers as nodes, and equivalent transmission lines as edges in the network topology model; add virtual connections between circuit breakers, busbars, and lines And simplify it to the edge in the network topology model, increase the virtual connection between the busbar and the transformer and simplify it to the edge in the network topology model. From this, the connec...

The invention proposes a method for establishing a rule base for grid switching operation based on rule mining. This method introduces data mining into the field of power grid scheduling. On the premise of preprocessing the historical archived power grid operation order tickets, the ant colony algorithm is used to search for potential classification rules, and the rules are pruned through the rule validity index to form rule base. The method proposed by the invention can be applied to different regions, effectively avoids problems such as rule base compatibility caused by regional differences, and can be widely used in automatic inspection systems and automatic generation systems of power grid operation instruction tickets. It can better assist the review of power grid operation order tickets, improve the efficiency and accuracy of power grid operation order ticket review, reduce the labor intensity of power grid dispatchers, reduce misoperations in power grid operations, and avoid economic losses.
Description
technical field [0001] The invention relates to the technical field of artificial intelligence for power grid dispatching operation, and more specifically, relates to a method for establishing a power grid switching operation rule base based on rule mining. Background technique [0002] With the continuous acceleration of my country's industrialization process, the continuous improvement of the economic level, and the continuous strengthening of power grid construction, the power network is becoming more and more complex. Correspondingly, the operation of the primary and secondary equipment involved in the power grid dispatching switching operation is becoming more and more complicated, and it is becoming more and more difficult to quickly and accurately fill in and review the power grid dispatching operation instruction ticket. Therefore, more and more researchers are trying to apply the research results of artificial intelligence to this field, and establish an artificial ...
