[0033] The principles and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are provided only to enable those skilled in the art to better understand and implement the present invention, and are not intended to limit the scope of the present invention in any way. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0034] Those skilled in the art know that the embodiments of the present invention can be implemented as a system, device, apparatus, method or computer program product. Therefore, the present invention can be specifically implemented in the following forms, namely: complete hardware, complete software (including firmware, resident software, microcode, etc.), or a combination of hardware and software.

[0035] It should be noted that any number of elements in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0036] Reference below Figure 1 , Figure 1 This is a schematic diagram of the structure of a dual-electric three-station isolation grounding operating system provided by an embodiment of the present invention. Figure 1 As shown, a dual-electric three-station isolation grounding operating system 100 includes:

[0037] A mapping module 101 is used to map power system equipment into operation objects, and obtain circuit breakers, disconnectors and grounding switches in the mapped equipment;

[0038] The state detection module 102 is used to detect the state of the operation object and obtain the state information of the device;

[0039] An acquisition module 103 is used to acquire the real-time operation status, isolation and grounding operation delay and isolation and grounding failure probability of the circuit breaker, the disconnector and the grounding switch respectively based on the status information of the device;

[0040] The evaluation module 104 is used to obtain the operation evaluation result of the dual-electric three-station isolation grounding operation system based on the real-time operation status, isolation grounding operation delay and isolation grounding failure probability of the operation, and use the operation evaluation result as the operation evaluation result of the power system equipment.

[0041] It should be noted that the dual-electric three-station isolation and grounding operating system of the present invention realizes the mapping of the operation objects of the power system equipment through a mapping module, which includes not only circuit breakers, disconnectors and grounding switches, but also other related power equipment, such as transformers, relays, etc. The purpose of the mapping module is to convert the status and operation requirements of these devices into a form that the system can understand and process.

[0042] Specifically, the mapping module needs to set the corresponding parameters according to the actual layout and equipment configuration of the power system. For example, the operation type, operation sequence, and time required for each device need to be accurately defined during the mapping process. In addition, the mapping module should also be able to identify and handle dependencies and operation conflicts between devices.

[0043] Preferably, the mapping module can use an intelligent algorithm to optimize the mapping process of the device. For example, through machine learning technology, the system can learn the usage patterns and operating habits of different devices, so as to automatically adjust the parameters during mapping to adapt to different operating scenarios. In addition, the mapping module can also integrate a fault detection mechanism, which can adjust the mapping strategy in time when an abnormal device status is detected to ensure the safety and effectiveness of the operation.

[0044] In some embodiments, the evaluation module includes: constructing a device utility expression for power system isolation and grounding operation based on the acquired real-time operation status, isolation and grounding operation delay, and isolation and grounding failure probability of the operation;

[0045] Based on the equipment utility expression for power system isolation and grounding operations and the failure rate of equipment isolation and grounding operations, the constraints and objective functions of operation evaluation are constructed;

[0046] Based on the constraints and objective function of the operation evaluation, an optimal solution for the operation evaluation is obtained;

[0047] The optimal solution of the operation evaluation is substituted into the equipment utility expression for the isolation and grounding operation of the power system to obtain the operation evaluation result.

[0048] It should be noted that the evaluation module is designed to provide a comprehensive analysis framework to evaluate the performance of the dual-electric three-station isolated grounding operation system. This not only involves real-time operation status monitoring, but also includes in-depth analysis of operation delay and success rate.

[0049] Specifically, the evaluation module will use the equipment utility expression to quantify the efficiency and effectiveness of the operation. This expression may include parameters such as the weights of real-time isolation and grounding operations and non-real-time operations, success rates, and average operation delays. For example, the weight parameters can be set based on the urgency and importance of the operation, while the success rate and delay are determined based on historical data and real-time monitoring results.

[0050] Preferably, the evaluation module can be further refined into several key steps: first, monitor the operating status of each device in real time, and record the start and end time of the operation to calculate the real-time operation delay; second, evaluate the success rate of the operation based on the historical performance and current status of the device; then, construct an objective function that comprehensively considers cost, timeliness and success rate, as well as corresponding constraints to determine the optimal operation plan; finally, by solving this objective function, the optimal solution for the operation evaluation is obtained, and the operation evaluation result is generated accordingly. In addition, the evaluation module can also design a feedback mechanism to adjust the parameters in the device utility expression according to the actual operation results to improve the accuracy of the evaluation.

[0051] In some embodiments, the utility expression of the device for power system isolation and grounding operation is: in, and Respectively represent the weights of the real-time isolation grounding operation and the non-real-time isolation grounding operation; and Respectively represent the success rates of real-time isolation and grounding operations and non-real-time isolation and grounding operations; and Respectively represent the average isolation grounding operation delay of real-time isolation grounding operation and non-real-time isolation grounding operation.

[0052] It should be noted that the construction of the equipment utility expression is the core part of the evaluation module, which integrates multiple factors such as real-time operation status, operation delay and success rate to quantify the comprehensive utility of the isolation and grounding operation of the power system.

[0053] Specifically, the parameters in the device utility expression, such as weight and , success rate and And the average operation delay and , need to be set according to the actual power system operation requirements and historical data. For example, the weight parameters can be adjusted according to the urgency and importance of the operation, while the success rate and delay may be optimized based on historical operation data and real-time monitoring results.

[0054] Preferably, the device utility expression can be further refined into the following steps: first, define weight parameters to reflect the priority of different types of operations; second, determine the success rate and average operation delay through real-time monitoring and data analysis; then, substitute these parameters into the device utility expression to calculate the comprehensive utility of each operation; finally, based on the calculation results, the evaluation module can sort the operations to determine the optimal operation sequence. In addition, in order to improve the accuracy and adaptability of the evaluation, an adaptive algorithm can be introduced to dynamically adjust these parameters in response to real-time changes in the power system state.

[0055] In some embodiments, the constraints for the operation evaluation are: ;in, Indicates the total number of equipment isolation and grounding operations in the power system; Indicates The cost of isolating and grounding each device, including the energy consumption budget; Indicates Is the device isolated and grounded? When the first device is isolated and grounded, the value is 1. When a device is not isolated and grounded, the value is 0; Represents the isolated ground operating budget.

[0056] It should be noted that the objective function of the operation evaluation is to optimize the isolation and grounding operation of the power system under a series of constraints. This objective function takes into account factors such as the total number of equipment isolation and grounding operations, operating costs, and budget to maximize cost-effectiveness.

[0057] Specifically, the parameters in the objective function are such as the total number of equipment isolation and grounding operations , the cost of each equipment isolation and grounding operation , Decision variables for whether to perform isolation and grounding operation and the isolated ground operating budget All need to be set according to the actual situation. For example, It can be determined according to the number of devices in the power system, and It may be calculated based on the importance of the equipment, difficulty of operation, and required resources.

[0058] Preferably, the objective function of the operation evaluation can be further refined into the following steps: first, determine the cost of each equipment isolation and grounding operation, which may include manpower, material and time costs; second, set a decision variable for each equipment on whether to perform isolation and grounding operation according to the importance of the equipment and the urgency of the operation; then, build a linear programming model to minimize the total cost or maximize the total utility while meeting the constraints of the operation budget; finally, use the optimization algorithm to solve the model and obtain the optimal equipment isolation and grounding operation plan. In addition, sensitivity analysis can be introduced to evaluate the impact of different parameter changes on the objective function to improve the robustness of the operation plan.

[0059] In some embodiments, the power system equipment includes circuit breakers, disconnect switches, and grounding switches;

[0060] The operation starting device includes a circuit breaker operation starting device and a disconnect switch operation starting device;

[0061] When the operation initiating device acts as the operation initiator, it is called the operation initiating device;

[0062] When an operation terminating device serves as the operation receiver, it is called an operation terminating device.

[0063] It should be noted that the dual-electric three-station isolation grounding operating system of the present invention pays special attention to the operation of circuit breakers, disconnectors and grounding switches in the power system. These devices are key components for the safe operation of the power system, and the correctness of their operation directly affects the stability and reliability of the system.

[0064] Specifically, the operation start device and the operation end device are two key nodes for the isolation and grounding operation in the power system. The operation start device is responsible for initiating the operation instructions, while the operation end device is responsible for receiving and executing these instructions. In practical applications, the circuit breaker operation start device may refer to the control center or automation system, while the isolation switch operation start device may be the on-site operator or remote control system. Parameter settings may include the sending time of the operation instruction, the execution time, and the confirmation feedback time of the operation.

[0065] Preferably, the operation steps can be further refined into the following key points: first, clarify the roles and responsibilities of the operation start device and the operation end device to ensure unimpeded communication between them; second, set the priority and execution order of the operation instructions to avoid operation conflicts and delays; then, track the execution status of the operation through a real-time monitoring system to ensure that the operation is carried out according to the predetermined plan; finally, a fault fallback mechanism can be introduced. When an abnormality occurs during the operation, the system can automatically switch to the backup operation path to ensure the safe operation of the power system. In addition, it is also possible to consider using artificial intelligence algorithms to optimize the generation and execution process of operation instructions and improve the intelligence level of operations.

[0066] In some embodiments, the isolation grounding operation delay The calculation formula is: in, Indicates the device from which the operation starts To the operation termination device The device set on the device operation path; and They represent the delay from the starting device to the network device and from the network device to the terminating device respectively; Represents the set of connections between all device operations on the device operation path; Represents the average isolation ground operation transition delay between any two device operation nodes.

[0067] It should be noted that the dual-electric three-station isolation grounding operation system of the present invention pays special attention to the calculation of isolation grounding operation delay. Operation delay is a key indicator to measure the system response speed and efficiency, and directly affects the safety and reliability of power system operation.

[0068] Specifically, the calculation of the isolation grounding operation delay involves the set of devices on all device operation paths from the operation start device to the operation end device. In this process, it is necessary to consider the delay from the start device to the network device and from the network device to the end device, as well as the set of connections between all device operations on the device operation path. Parameter settings may include the operation preparation time, execution time, and communication delay between devices for each device.

[0069] Preferably, the calculation of the isolated grounding operation delay can be further refined into the following steps: first, define the expected time and possible delay factors of each device operation; second, collect the operation data of each device through the real-time monitoring system, including the timestamps of the start and end of the operation; then, calculate the total delay from the operation start device to the end device, which includes the processing time of all intermediate devices and the communication time between devices; finally, statistical methods or machine learning algorithms can be used to predict and optimize the operation delay to reduce the uncertainty in the operation process. In addition, a dynamic adjustment mechanism can be designed to dynamically adjust the prediction model of the operation delay according to real-time data and historical trends to improve the accuracy of the prediction.

[0070] In some embodiments, when an operation initiating device sends an operation to a terminating device via a device operation node, an isolation ground processing delay is included. and isolation ground transition delay , isolation ground transition delay Including access preparation delay , Execution delay , the calculation formula is: in, Represents a collection of device operation nodes on an operation path.

[0071] It should be noted that the dual-electric three-station isolation grounding operating system of the present invention further elaborates on the calculation method of the isolation grounding conversion delay. This step is a key link to ensure smooth operation, involving the set of equipment operation nodes on the operation path and the interaction between them.

[0072] Specifically, the isolation grounding conversion delay includes the access preparation delay and the execution operation delay, which affect the efficiency of the entire isolation grounding operation. Parameter settings may involve measuring the response time and processing time of each device operation node, as well as their location and function on the operation path. For example, represents the access preparation delay from the operation start device to a certain device operation node, and Indicates the execution operation latency of the node.

[0073] Preferably, the calculation of the isolation grounding transfer delay can be further refined into the following steps: first, determine the set of all device operation nodes on the operation path and assign a unique identifier to each node; second, measure and record the access preparation delay and execution operation delay of each node; then, calculate the cumulative delay from the operation start device to the end device through each node; finally, an optimization algorithm can be used to minimize the total isolation grounding transfer delay to ensure a fast response of the operation. In addition, a real-time monitoring system can be designed to track the status of each node so that the operation plan can be adjusted in time when delays occur.

[0074] More specifically, thresholds can be set for each device operation node to ensure that they complete preparation and execution within the specified time. For example, if the execution delay of a node exceeds the preset threshold, the system can automatically reallocate the operation task or adjust the operation sequence to avoid affecting the progress of the entire operation process. In addition, a prediction mechanism can be introduced to predict possible delays based on historical data and current status, and take measures in advance to reduce operation delays.

[0075] In some embodiments, the isolation ground processing delay The calculation formula is: in, It represents the total delay required for status detection of power system equipment; Represents a set of device operation nodes on the operation path; Represents a device operation node Isolation ground processing delay.

[0076] It should be noted that the dual-electric three-station isolation grounding operating system of the present invention further clarifies the calculation method of the isolation grounding processing delay. This step is crucial to ensure the accuracy and efficiency of the operation, and involves the total delay required for status detection of power system equipment.

[0077] Specifically, the isolation grounding processing delay includes the total delay of status detection of power system equipment and the isolation grounding processing delay of the equipment operation node. Parameter setting may involve the measurement of the detection time, processing time and response time of each equipment operation node. For example, represents the total delay required to detect the status of all devices, and Represents the isolation ground processing delay of a specific device operation node.

[0078] Preferably, the calculation of the isolation grounding processing delay can be further refined into the following steps: first, define the detection and processing process of each device operation node; second, measure and record the isolation grounding processing delay of each node; then, calculate the total delay from the start of the operation to the completion of all device status detection; finally, an optimization algorithm can be used to minimize the total isolation grounding processing delay to ensure the rapid completion of the operation.

[0079] More specifically, performance indicators can be set for each device operation node, such as the maximum allowed detection and processing delay. If the actual delay of a node exceeds this indicator, the system can automatically adjust the operation strategy, such as reallocating tasks or optimizing the detection process. In addition, machine learning algorithms can be introduced to analyze historical operation data, predict possible delay bottlenecks, and optimize them in advance. A feedback mechanism can also be designed to dynamically adjust the delay prediction model based on real-time operation data to improve the response speed and accuracy of operations.

[0080] In some embodiments, the isolated ground failure probability of operation The calculation formula is: in, and Respectively represent device operation nodes The probability of preparation failure and execution failure; Represents the set of connections between all device operations on the operation path; Indicates link The probability of isolated ground link failure.

[0081] It should be noted that the dual-electric three-station isolation grounding operation system of the present invention provides a method for calculating the isolation grounding failure probability of the operation. This calculation is crucial for evaluating and optimizing the safety of power system operation.

[0082] Specifically, the calculation of the isolation grounding failure probability involves the preparation failure probability, execution failure probability of the device operation node, and the isolation grounding link failure probability of the link. Parameter settings may include estimating the failure probability of each device operation node and evaluating the link reliability. For example, represents the probability of failure in the preparation of device operation node i, represents the probability of execution failure, and represents the isolated ground link failure probability of link ij.

[0083] Preferably, the calculation of the isolation grounding failure probability can be further refined into the following steps: first, collect and analyze the historical operation data of each device operation node to estimate the failure probability in the preparation and execution stages; second, evaluate the reliability of the link and determine the isolation grounding failure probability between links; then, combine these probabilities to calculate the isolation grounding failure probability on the entire operation path; finally, statistical methods or machine learning algorithms can be used to improve the accuracy of failure probability estimation.

[0084] More specifically, thresholds for the probability of failure can be set for each device operating node and link to ensure the safety of operation. If the calculated probability of failure exceeds these thresholds, the system can automatically trigger an early warning mechanism or take preventive measures, such as switching to an alternate operating path or increasing the redundancy of the operating node. In addition, the system can monitor the status of the operating nodes and links in real time and dynamically update the estimate of the probability of failure to adapt to changes in the operating environment. An adaptive optimization algorithm can also be designed to adjust the operating strategy based on real-time feedback to minimize the risk of isolated grounding failure.

[0085] The above-mentioned embodiments of the present invention have the following beneficial effects: by implementing the dual-electric three-station isolation grounding operation system, the automation level and efficiency of the isolation grounding operation of the power system can be significantly improved. The system can accurately map the power system equipment and obtain key operation information through real-time status detection and comprehensive evaluation mechanism, thereby optimizing the operation process and reducing human errors. In addition, the system can also evaluate the timeliness and cost-effectiveness of the operation to ensure the optimal allocation of resources and rapid response of operations under the premise of meeting safety standards. Further, the system can identify and prevent potential operational risks in advance and enhance the reliability and stability of the power system through refined delay and failure probability calculation. By constructing equipment utility expressions and constraints and objective functions of operation evaluation, the system can optimize the operation plan and improve the success rate of isolation grounding operations. At the same time, the system can also adapt to different operation scenarios and requirements, and continuously improve the accuracy of operation evaluation and the intelligent level of operation execution through dynamic adjustment and adaptive learning.
