Description

An intelligent method for drafting votes

technical field

The invention relates to the technical field of electric power systems, in particular to an intelligent ticket drafting method.

Background technique

The process of dispatching order tickets is divided into five steps: drafting, reviewing, pre-ordering, executing, and filing.

Figure simulation ticket refers to manually selecting the required equipment or line in the equipment electrical contact topology diagram, selecting the operation type, importing the work content, and the system automatically generates a dispatching instruction ticket during the drafting stage. At present, the basis of the map simulation ticket is that the map model is correct. One of the problems is that after the information and data of the equipment and its contact relationship are collected and integrated, the format of these data is not uniform, the content is conflicting with each other, and the system cannot be as correct as manual work. If the identification cannot be correctly formed, the instruction ticket cannot be correctly generated; the conflict is generally that the old and new contact relationships coexist, the same device has different names, and different devices have the same name. The graph model refers to a visual graph model, and the model refers to a node connection relationship. Another problem is that the graph data provider does not know the user, and often provides data that is much larger than the required range, resulting in more and more useless data, and the system itself cannot identify these useless garbage data, resulting in slow software loading or memory overflow. . The current voting method cannot effectively solve these problems.

For example, Chinese patent CN102096856A, published on June 15, 2011, a method for generating a schematic diagram of a power production work ticket based on a power grid topology includes the following steps: Step 1: Initialize parameters for generating a schematic diagram of a work ticket; Step 2: The grid topology is extracted to create a simplified topology structure that is convenient for generating a work ticket sketch; Step 3: According to the simplified topology structure, a work ticket sketch is generated. By combining the business requirements and the generation rules of the work ticket diagram, the power production work ticket diagram can be automatically generated, which is convenient to guide the maintenance work of the on-site maintenance personnel. However, it does not consider the problems of conflicting data contents in the proposed ticket and excessive useless data, which leads to slow software loading or memory overflow.

SUMMARY OF THE INVENTION

If the conflicting graph modes are associated with a chain pointer, which is the relationship between the root graph and the subgraph, it is considered that the upper layer topology of the subgraph is consistent with the root graph, and the topology of the two graphs is consistent. For example, the node-branch correlation matrix corresponding to the upper topology in the subgraph and the root graph is A and B. Due to conflicts, if A is not equal to B, but TAE=B and |T|=1, |E |=1, it is considered that the topologies of the two graphs are still the same, and the elements with high priority in the topology are named to cover the elements with low priority.

Step 1: Enter the automatic ticket preparation link;

Step 2: Display the area and manually selected elements, mark the first-type elements, and record the priority as 0; the first-type elements are the middle section of line 1, switch 2 and the middle section of line 2.

Step 3: Set all switches to the closed conduction state, start with the elements of the first type of graph, take the power point of the same voltage level as the end point, and search in the correlation matrix, the elements of the same electrical node are marked as the second type, The priority is recorded as 1, that is, the equipment or line from the first class diagram to the secondary side of the transformer is the second class, and the priority is 1; the second class is the entire line of line 1 and line 2 except the first class.

Step 4: In the diagram simulation ticket software, in the diagram template that has been opened but not displayed, the elements that are not marked as the second category or the first category, the rest are marked as the third category, and the priority is recorded as 2;

Step 5: Remove the first three categories, and the remaining elements are not marked, they are the fourth category, and the fourth category has a priority of 3.

Step 6: In the automatic ticket drafting link, topology analysis, when the diagram and model conflict, go to Step 7, otherwise go to Step 9;

Step 7: If there are elements with the same name in the conflicting patterns, the topology of the high-priority element shall prevail; otherwise, go to Step 7;

Step 8: If the conflicting graph modes are associated with a chain pointer, which is the relationship between the root graph and the subgraph, it is considered that the upper topology of the subgraph is consistent with the root graph, and the topological consistency of the two graphs is checked, for example, the subgraph The node-branch correlation matrices corresponding to the upper-layer topology and the root graph are A and B. Due to conflicts, if A is not equal to B, but TAE=B and |T|=1, |E|=1, it is considered that the two-graph topology is still Consistently, overwrite low-priority elements with high-priority element names in the topology;

Step 9: The automatic ticket preparation ends, and the element's mark is cleared.

The above examples only represent several embodiments of the present invention, and the descriptions thereof are specific and detailed, but should not be construed as a limitation on the scope of the invention patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can also be made, which all belong to the protection scope of the present invention.
