As shown in fig. 1, the method, system and storage medium for scheduling and calling the grid fault handling computing task includes the following steps:
step one, constructing a power grid fault disposal plan professional dictionary. The method mainly comprises the following steps: station name, equipment name, area name, index scenario, etc. The plant names comprise a power plant and a transformer substation name set; the equipment names comprise various main primary electrical equipment name sets of the power grid; the region name comprises a main regulation region name set; the index scene is a set of main indexes of the power grid operation, including power flow, voltage, frequency, output and load. For example:
the plant names { "a plant station", "B plant station", "C plant station" … };
the equipment names { "a line", "B line", …, "a bus", "B bus", …, "a unit", "B unit", … };
the area names { "area a", "area B", "area C" … };
the index scenario is { "power flow", "voltage", "output", "load", … }.
And step two, matching and extracting associated equipment objects and index scenes corresponding to fault equipment handling key points in the power grid accident handling plan according to the accident plan professional dictionary, and storing extracted fault handling information according to a tuple chain structural form of 'fault equipment-index scene-associated equipment' to obtain fault handling tuple chain information.
For example: for the A line fault in the plan, after matching and extraction of the professional dictionary, the processing equipment object and the index scene related to the A line fault form fault processing tuple chain information, such as 'A line-tidal current-B line', 'A line-voltage-C bus', 'A line-output-D unit'.
And step three, matching fault equipment elements in the fault handling tuple chain information one by one according to actual fault equipment identified by online diagnosis of the power grid fault, and obtaining all fault handling tuple chain information sets containing the actual fault equipment.
For example: for the fault of the line A diagnosed on line by the power grid fault, all fault handling tuple chain information related to the fault of the line A, such as the line A, the tide line B, the line A, the voltage line C and the line A, the output line D, is obtained by matching the fault equipment elements in the fault handling tuple chain information on line.
And step four, automatically extracting and arranging related calculation task sequences from all calculation tasks according to the fault equipment associated fault handling tuple chain information set obtained by online matching and the index scene related to the tuple chain information set, calling the corresponding calculation task sequences by using the associated equipment as a calculation parameter, and calculating to obtain related operation index state data of the associated equipment.
For example: according to the A line fault handling tuple chain information set obtained through online matching, three index scenes mainly related to tidal current, voltage and output can be analyzed, and related equipment mainly comprises a line B, a bus C and a unit D. Therefore, for the calculation task of the line A fault, three calculation tasks of load flow analysis, voltage analysis and unit output analysis are automatically extracted from all the calculation tasks provided by the system, the analysis sequences are arranged, then the corresponding calculation task sequences are called by taking the associated equipment as the calculation parameters, and finally the relevant operation index state data of the associated equipment is obtained through calculation.
And fifthly, collecting and summarizing the related analysis results obtained by automatic arrangement and calling of the calculation tasks, and displaying the results in a centralized manner through a uniform interface. The display content mainly comprises: current failure equipment, disposal associated equipment, index scene type, index scene pre-failure value, index scene post-failure value, index scene variation percentage, index scene limit value, index scene state (such as out-of-limit and heavy load) and the like.
