Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0042] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. The terms "comprising" and "having," and any variations thereof, used in this application, are intended to cover non-exclusive inclusion. The term "multiple" used in this application refers to two or more. The term "and / or" used in this application refers to one of the embodiments, or any combination of multiple embodiments.

[0043] In one embodiment, such as Figure 1 As shown, a method for mode-case derivation in a power system is provided. This embodiment illustrates the application of this method to a terminal. It is understood that this method can also be applied to a server, and further to a system including both a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0044] Step 102: Load the multi-source mode list of the power system. For any mode list, analyze whether there is an abnormal operation mode in the mode list, obtain the analysis result of the mode list, and determine whether the mode list can be deduced based on the analysis result.

[0045] Among them, multi-source mode orders refer to multiple mode orders. Multi-source mode orders are loaded collaboratively, supporting the combined selection of mode orders across time periods / scenes, automatically recording historical operation trajectories, and establishing mode order feature maps, including metadata such as operation sequence timestamps and device-related parameters. After loading, intelligent verification and anomaly warnings are performed. For any mode order, the on / off operation sequence and execution time window of that mode order are parsed, and abnormal operation patterns (such as timeout instructions, unauthorized operations, etc.) are identified through a pre-verification engine, generating a visualized warning report in real time that includes the violation type and risk level.

[0046] Step 104: If the judgment result shows that the mode sheet can be simulated, then perform real-time state fusion simulation based on the mode sheet and the real-time operation data stream of the power system to generate a first simulation result; perform single-step operation simulation on the mode sheet to generate a second simulation result; and perform spatiotemporal correlation analysis on the mode sheet to generate a third simulation result.

[0047] Among them, fusion simulation, single-step operation simulation, and spatiotemporal correlation analysis are three parallel tasks.

[0048] Step 106: Based on the pre-established power system model and the method sheet, generate visualization results of the analytical results, the first simulation results, the second simulation results, and the third simulation results.

[0049] After the simulation is completed, a visualization result will be generated, which can show the impact of each operation according to the operation steps in the method sheet, making it convenient for staff to modify and maintain.

[0050] The aforementioned power system mode order simulation method, apparatus, computer equipment, computer-readable storage medium, and computer program product load multiple mode orders of the power system. For any mode order, it analyzes whether the mode order has an abnormal operation mode, obtaining the analysis result of the mode order. Based on the analysis result, it determines whether the mode order can be simulated. If the determination result shows that the mode order can be simulated, it performs real-time state fusion simulation based on the mode order and the real-time operation data stream of the power system to generate a first simulation result; it performs single-step operation simulation on the mode order to generate a second simulation result; it performs spatiotemporal correlation analysis on the mode order to generate a third simulation result; and based on a pre-established power system model and the mode order, it generates a visualization result of the analysis result, the first simulation result, the second simulation result, and the third simulation result. This allows for simulation by simultaneously loading multiple mode orders and visualizes the simulation results.

[0051] In an exemplary embodiment, the real-time state fusion simulation based on the mode sheet and the real-time operation data stream of the power system to generate a first simulation result includes:

[0052] The real-time operation data stream of the power system is acquired, and a spatiotemporal cube of equipment status is constructed based on the real-time operation data stream. The spatiotemporal cube of equipment status includes three-dimensional coordinates of time, space and electrical status. Based on the spatiotemporal cube of equipment status, a real-time state fusion simulation is performed on the mode form to generate the impact results of the mode form on the topology connection status, protection device operation logic and load distribution trend. The impact of the mode form on the topology connection status, protection device operation logic and load distribution trend constitutes the first simulation result.

[0053] Optionally, the real-time operation data stream of the power system can be a SCADA / PMU real-time data stream.

[0054] Among them, SCADA (Supervisory Control and Data Acquisition) collects second-level steady-state data of power grid equipment through sensors and actuators, including voltage amplitude, current, power, and switch status. PMU (Phasor Measurement Unit) uses GPS timing to synchronously measure the voltage / current phasors (amplitude + phase angle) of power grid nodes with millisecond-level accuracy.

[0055] For example, real-time data streams from SCADA / PMU are acquired, and a spatiotemporal cube representing the device status is constructed based on these data streams. The spatiotemporal cube includes three-dimensional coordinates of time, space, and electrical status. Based on the spatiotemporal cube, a real-time status fusion simulation is performed on the mode statement to generate the impact results of the mode statement on the topology connection status, protection device operation logic, and load distribution trend. The impact of the mode statement on the topology connection status, protection device operation logic, and load distribution trend constitutes the first simulation result.

[0056] In this embodiment, by performing real-time state fusion simulation on the mode sheet using real-time data streams, the impact of the operations in the mode sheet on the electrical system can be obtained more accurately.

[0057] In an exemplary embodiment, the step of performing a single-step operation deduction on the method to generate a second simulation result includes:

[0058] Based on a single-step operation simulation, the mode order is subjected to time window compliance verification and the topology penetration depth of the mode order is predicted. Based on the time window compliance verification result and the predicted topology penetration depth of the mode order, an operation suggestion sequence for the mode order is generated, and the operation suggestion sequence is used as the second simulation result.

[0059] Optional time window compliance verification includes: Static rule verification: checking whether the operation is executed within the planned time window (e.g., avoiding timeout operations); verifying operation permissions (e.g., prohibiting unauthorized personnel from operating high-voltage equipment). Dynamic safety verification: simulating the grid state after the currently operating equipment is taken out of operation (e.g., disconnecting a line); verifying whether other equipment is overloaded (load rate ≤ 100%) and whether the node voltage exceeds the limit (±5%~±10% offset).

[0060] The proposed operational sequence includes optimized solutions for modifying the operational steps in the moderation sheet. The topology penetration depth of the moderation sheet is predicted to be limited to a maximum of 15 electrical layers.

[0061] Optionally, time window compliance verification can be performed using the N-1 criterion.

[0062] For example, based on a single-step operation simulation, the method sheet is checked using the N-1 criterion, and the topology penetration depth of the method sheet is predicted, with a maximum depth of 15 layers. Based on the time window compliance check result and the predicted topology penetration depth of the method sheet, an operation suggestion sequence for the method sheet is generated, and the operation suggestion sequence is used as the second simulation result.

[0063] In this embodiment, by performing a step-by-step operation simulation on the mode sheet, the impact of each operation in the mode sheet on the electrical equipment can be obtained.

[0064] In an exemplary embodiment, the step of performing spatiotemporal correlation analysis on the mode list to generate a third simulation result includes:

[0065] Spatiotemporal correlation analysis is performed on the aforementioned method sheet to generate time window overlap results, operation order reversal results, and protection logic mutual exclusion results; based on the time window overlap results, operation order reversal results, and protection logic mutual exclusion results, an operation timing conflict matrix is ​​constructed; based on the operation timing conflict matrix, a risk heatmap and optimization suggestion path are generated; the risk heatmap and optimization suggestion path constitute the third simulation result.

[0066] Among these, the risk of overlapping time windows is identified by using a sliding window algorithm to scan the operation time axis. If the intersection of two operation time windows exceeds a threshold (e.g., ≥30%), it is marked as an overlapping risk. The risk of reversed operation order is identified by using a directed graph topology sort to verify operation dependency chains (e.g., "stopping the transformer before disconnecting the load" is a forward order). If the load is disconnected before the transformer is stopped, it may cause a voltage surge and damage the equipment. The risk of mutual exclusion in protection logic is identified by using knowledge graph reasoning to determine the action logic of protection devices (e.g., the coordination relationship between overcurrent protection and differential protection) and to identify setting conflicts or contradictory action timing.

[0067] For example, spatiotemporal correlation analysis is performed on the mode order to detect operations in the mode order where the intersection of operation time windows exceeds a threshold (e.g., ≥30%), verify the operation dependency chain of the mode order, and identify value conflicts or action sequence contradictions in the mode order. Time window overlap results, operation order reversal results, and protection logic mutual exclusion results are generated respectively. Based on the time window overlap results, operation order reversal results, and protection logic mutual exclusion results, an operation sequence conflict matrix is ​​constructed. Based on the operation sequence conflict matrix, a risk heatmap and optimization suggestion path are generated. The risk heatmap and optimization suggestion path constitute the third simulation result.

[0068] In this embodiment, potential conflicts between operation instructions in the mode sheet are analyzed by integrating time and space dimensions, three types of key risks are identified (overlapping time windows, reversed operation order, and mutually exclusive protection logic), and an optimization path is provided based on the risk heat map, which can ensure operational safety and efficiency.

[0069] In one exemplary embodiment, the process of constructing the power system model includes:

[0070] Based on the power public information model, a two-dimensional topology matrix is ​​constructed; based on the two-dimensional topology matrix, a device operation impact propagation tree is established, which includes: first-level nodes of directly connected devices, second-level nodes of electrically related devices, and third-level nodes of protection logic related devices; the two-dimensional topology matrix and the device operation impact propagation tree together constitute the power system model.

[0071] For example, using the common information model of the international standard IEC 61970, power grid equipment is abstracted as objects (such as transformers, switches, and buses), and connection rules between devices (such as electrical connections and topology nesting) are defined. The rows and columns of the matrix represent device IDs, forming an N×N grid (N is the total number of devices), and a two-dimensional topology matrix is ​​constructed. Based on the two-dimensional topology matrix, a device operation influence propagation tree is established, which includes: first-level nodes of directly connected devices, second-level nodes of electrically associated devices, and third-level nodes of protection logic associated devices. The two-dimensional topology matrix and the device operation influence propagation tree together constitute the power system model.

[0072] In this embodiment, by constructing a power system model, the transmission path of operational impacts can be accurately quantified.

[0073] In one exemplary embodiment, the method further includes:

[0074] If the judgment result shows that the method order cannot be deduced, then the method order will not be deduced, and the violation type of the method order will be generated according to the abnormal operation mode.

[0075] When the operation in the method order presents a significant risk, a circuit breaker mechanism will be triggered, meaning that the result indicates that the method order cannot be used for simulation, and subsequent simulations will be terminated.

[0076] For example, if the judgment result shows that the method order cannot be deduced, then the method order will not be deduced, and the violation type of the method order will be generated according to the abnormal operation mode.

[0077] In this embodiment, system resources can be saved by stopping the simulation of mode sheets that involve operations with significant risks.

[0078] In one exemplary embodiment, such as Figure 2As shown, a method for power system mode order simulation includes: loading multi-source mode orders of the power system; for any mode order, analyzing whether the mode order has an abnormal operation mode to obtain the analysis result of the mode order; and determining whether the mode order can be simulated based on the analysis result. If the determination result shows that the mode order cannot be simulated, then the mode order is not simulated, and a violation type of the mode order is generated according to the abnormal operation mode. If the determination result shows that the mode order can be simulated, then real-time SCADA / PMU data streams are acquired, and a device status spatiotemporal cube is constructed based on the SCADA / PMU real-time data streams; the device status spatiotemporal cube includes three-dimensional coordinates of time, space, and electrical status; based on the device status spatiotemporal cube, real-time status fusion simulation is performed on the mode order to generate the impact result of the mode order on the topology connection status, protection device operation logic, and load distribution trend, and the impact of the mode order on the topology connection status, protection device operation logic, and load distribution trend constitutes the first simulation result. Based on a single-step operation simulation, the mode order is validated using the N-1 criterion, and its topology penetration depth is predicted, with a maximum depth of 15 layers. Based on the time window compliance validation results and the predicted topology penetration depth of the mode order, an operation suggestion sequence is generated, which is used as the second simulation result. Spatiotemporal correlation analysis is performed on the mode order to detect operations where the intersection of operation time windows exceeds a threshold (e.g., ≥30%), validate the operation dependency chain, and identify setting conflicts or action sequence contradictions. Time window overlap results, operation order reversal results, and protection logic mutual exclusion results are generated respectively. Based on these results, an operation sequence conflict matrix is ​​constructed. A risk heatmap and optimized suggested paths are generated based on the operation sequence conflict matrix. The risk heatmap and optimized suggested paths constitute the third simulation result. Based on a pre-established power system model and the mode order, visualization results of the analytical results, the first simulation result, the second simulation result, and the third simulation result are generated. The construction process of the power system model includes: adopting the common information model of the international standard IEC 61970, abstracting power grid equipment as objects (such as transformers, switches, and buses), and defining the connection rules between equipment (such as electrical connections and topology nesting). The rows and columns of the matrix represent equipment IDs, forming an N×N grid (N is the total number of equipment), and constructing a two-dimensional topology matrix; based on the two-dimensional topology matrix, establishing a device operation influence propagation tree, which includes: first-level nodes of directly connected devices, second-level nodes of electrically associated devices, and third-level nodes of protection logic associated devices; the two-dimensional topology matrix and the device operation influence propagation tree together constitute the power system model.
