[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention provides a simulation preview verification method based on a new equipment commissioning plan of a power grid main network, comprising the following steps:

[0029] Step 1: The scheduling plan content is analyzed and structured. The standard scheduling implementation plan compiled by the user is imported, and the imported plan is analyzed and converted into structured tree structure data according to chapters and paragraphs;

[0030] Step 2: Obtain plant model data, plant equipment ledger, equipment topology, and SVG format wiring diagram;

[0031] Step 3: Structured tree structure data analysis and equipment matching. For primary equipment, match the corresponding operating equipment from the plant model data in the equipment status verification and experimental operation steps chapters, and bind the operating status of the equipment. For protection equipment, extract the protection equipment in the tree structure and record the status of the protection equipment;

[0032] Step 4: Dynamically generate the SVG wiring diagram, based on the original SVG wiring diagram, and modify the device primitives in the SVG content for the devices and states in each step;

[0033] Step 5: Verify the solution content. Create a preview verification page for the final structured data to display the solution content and the corresponding wiring diagram.

[0034] Among them, in the scheduling plan, a plan database is established in advance, and the standard implementation plans in the database are directly imported through the computer.

[0035] Preferably, in structured analysis, information is extracted from the imported original solution, features are identified on the extracted information, and corresponding information is generated. The acquired information is converted into a word vector containing professional label interpretations, key entities in the word vector are identified, and the associations between the key entities are extracted and identified to complete the structured analysis of the solution content data.

[0036] Furthermore, in the analysis of structured tree structure data, a temporary variable is used to loop through the data list generated by the hierarchical associated data, the root data of the data list is read, the tree node characteristics in the data list are used to build the threshold condition in combination with the temporary data set, and the tree code is set in ascending order for the tree nodes that meet the threshold condition, and then the tree code corresponding to the current tree node in the data list is stored in the temporary data set. At the end of the loop, a complete tree-shaped temporary data set relative to the data list is obtained.

[0037] In addition, in device matching, for model data, the master node groups the configuration parameters of the model, and assigns the configuration parameters of each group to the corresponding slave nodes. Each slave node configures the model according to the grouped configuration parameters. For multiple model data with different grouped configuration parameters for each configuration, the slave nodes are controlled to determine the performance data of each model and feedback the performance data. The master node receives the model performance data fed back by each slave node, and determines the optimal configuration parameters of each model based on the performance data. The master node controls at least two slave nodes to input the target data set into each model configured with the optimal configuration parameters, and determines the performance data of each model. The master node determines the model that best matches the target data set and is configured with the optimal configuration parameters based on the performance data of each model fed back by at least two slave nodes.

[0038] Among them, in the protection device, the operation data of each device is obtained, and based on the operation data, a status monitoring model of the device identification is constructed to obtain a preset device identification list, which includes the device identification. For each device identification, the full life cycle corresponding to the device identification is obtained, and during the full life cycle, data is collected from the device at regular intervals to obtain the initial operation data of the device identification. The initial operation data includes the device identification, device parameters and device parameter values. The device parameters are used to characterize the operation status of the device corresponding to the key device identification. The initial operation data is preprocessed to obtain reference data, and the reference data is stored in the operation database. According to the obtained device identification, the reference data corresponding to the device identification is obtained from the operation database as the operation data, and the device is protected in combination with the real-time monitoring data.

[0039] Furthermore, real-time monitoring data includes:

[0040] Operation parameter monitoring module: monitors the equipment parameters during the operation of the equipment;

[0041] Temperature monitoring module, which monitors the temperature of the equipment during operation;

[0042] The humidity monitoring module monitors the humidity of the equipment during operation.

[0043] In the dynamic generation of SVG wiring diagram, based on topological data, using graph database and reachability analysis algorithm, the busbar is set as the initial node, and depth-first search (DFS) is used to find all nodes reachable from the starting node. The reachable node information is obtained as the power-on path, and the color of the graphic element on SVG is modified according to the power-on path.

[0044] In the dynamic generation of the SVG wiring diagram, the SVG content generated in each step is stored, so that each operation step will eventually generate an SVG wiring diagram.

[0045] Among them, during the verification of the plan content, the protection equipment status in the data is used to display the protection equipment status list at each link, so that the operator can clearly know the status of the protection equipment at which step.

[0046] The present invention also provides another embodiment, and the specific steps are as follows:

[0047] Step 1: Data conversion. After the user has compiled the standard scheduling implementation plan, the system uploads it. The system uses the open source framework POI technology to parse the WORD, and parses the plan content into a hierarchical data structure in a tree structure according to the chapters and paragraphs.

[0048] Step 2: Plant model data matching, obtain plant information according to the work report chapter, and then obtain equipment ledger, topology data, and wiring diagram in SVG format;

[0049] Step 3: Initialize and identify the equipment status. According to the tree-structured data, find the equipment status verification section. According to the plant name and equipment name data in the content, match the equipment object from the plant model data to update the structured data, and initialize the equipment status to the cold standby state.

[0050] Step 4: Identify the equipment operation steps. The logic is consistent with the above. According to the equipment operated in the test steps and combined with the plant model data, the equipment ID is obtained.

[0051] Step 5: Extract protection device data. The status of the protection device can be seen during the test verification process, and the protection device status is extracted in the test step;

[0052] Step 6: Dynamically generate the SVG wiring diagram. The original SVG wiring diagram obtained from the plant model data is used as a benchmark. By checking the device status and extracting and mapping the data in the test steps, the operated equipment is matched with the plant model data, and the storage of the device status is completed. By combining the structured storage data of the solution content with the SVG data content, the device status is checked and the equipment with changed status in the test steps is matched with the graphic element equipment in the SVG content. After the matching is completed, the xlink:href value of the graphic element is modified. After the xlink:href value is modified, the device is on the wiring diagram. The display will be changed accordingly. After changing the equipment status of each step, a new SVG diagram content is obtained. According to the topological relationship of the plant model data and the extracted equipment status, such as the operation of the busbar and the operation of the switch, the graph database is used according to the operation status of the busbar and the switch. According to the graph query language, the power-on path of the equipment is obtained. The equipment in the power-on path is updated one by one to the color attribute of the equipment graphic element in SVG, and the color attribute is changed to red. The wiring diagram of each step in the equipment status verification and experimental steps will be obtained, and the SVG image path (svgPath) is stored in the structured data;

[0053] Step seven, solution content verification, through the final structured data, get the wiring diagram corresponding to each step, then provide a solution content verification function, display the content in the structured data according to the tree UI, layout, and provide the click time for each row of records, after clicking, a corresponding wiring diagram will be displayed, through the structured data, the protection device list will also be extracted, the protection list will also be displayed on the verification page, the user can clearly know that the solution uses the corresponding protection device, and click the protection device operation on the tree UI, the protection device status value will be displayed on the protection list, so that the user knows the status of the protection device when operating any one of them.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
