With the growth of energy demand, the improvement of environmental protection requirements and the development of power system technology, the access of distributed generation to the distribution network has become an important trend in the development of the global power system. With the development of social economy, global energy demand continues to grow. As a supplementary energy source, distributed generation can improve the diversity and reliability of energy supply and meet the growing energy demand. Traditional fossil energy power generation methods such as coal and oil have caused serious pollution to the environment.

[0003] However, with the access of distributed power sources, the structure of the distribution network automation system has become particularly complex, involving multiple technical fields and professional equipment, resulting in great difficulty in operation and maintenance. In addition, the current fixed value setting calculation adopts an offline management state, and paper version of the fixed value file is used for reporting, which requires a lot of manpower, material resources and time, and there is no unified method and system to manage the network-related fixed value data, which requires an automated processing method. The present invention proposes a remote operation and maintenance collaborative control method for distribution automation terminals, which effectively solves the current problems in fixed value setting calculation by introducing automated fixed value setting calculation methods, electronic fixed value file management, unified management of network-related fixed value data, automated verification and alarm, training and technical support and other measures.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Example 1, reference Figure 1-Figure 4 , which is the first embodiment of the present invention, and which provides a distribution automation terminal remote operation and maintenance collaborative control method, including: Figure 1 As shown:

[0027] Step 1: The main network OMS system pushes the fixed value list information to the distribution network OMS system, and the distribution network OCS pushes the full amount of terminal information data to the distribution network OMS. Figure 2 shown.

[0028] Based on the inter-system collaborative interface, the main network OMS system pushes the set value order information to the distribution network OMS system at the set value order receipt business process node, and the distribution network OMS system receives it under the set value order module.

[0029] Since the main network OMS currently only implements the fixed value approval process management function, there is no fixed value interface between it and the distribution network OCS, and it is impossible to review and modify the fixed value. Therefore, the main network OMS pushes the fixed value order to the distribution network OMS through the interface. The distribution network OMS system receives the fixed value order pushed by the main network OMS system at the "fixed value order receipt" business process node through the inter-system collaborative interface, and manages the fixed value order under the fixed value order module.

[0030] The distribution network OCS pushes the full amount of terminal information data to the distribution network OMS every day, and the distribution network OMS receives the terminal information to the distribution network terminal module.

[0031] Since the distribution network OMS currently has problems with missing terminal ledgers and untimely updates, in order to solve this problem, the distribution network OCS pushes terminal information to the distribution network OMS system through an interface. The distribution network OMS system receives the full amount of distribution network OCS terminal information data through the inter-system coordination interface, and receives the terminal information to the distribution network terminal module for management.

[0032] Step 2: The distribution network OMS system applies for a fixed value based on the fixed value order information and terminal information. After the fixed value application is reviewed and approved, the original fixed value is called. Figure 3 shown.

[0033] The distribution network OMS system creates a fixed value application form based on the fixed value order number in the fixed value order information, and automatically imports the terminal information by selecting the corresponding terminal.

[0034] In order to achieve coordination among the distribution network OMS, main network OMS and distribution network OCS systems, the distribution network OMS applies for set values ​​based on the set value list pushed by the main network OMS and the terminal information pushed by the distribution network OCS.

[0035] After the application is filled out, the fixed value application form will be reviewed three times, and the fixed value call will be made for the fixed value application form that has completed the three reviews. After the three reviews are completed, the distribution network OMS will send the command to call the actual fixed value of the terminal to the distribution network OCS system. The distribution network OCS system will return the fixed value item corresponding to each information body of the terminal to the distribution network OMS, and the distribution network OMS will fill in the original value of the corresponding information body according to the returned information.

[0036] The fixed value application form is reviewed three times in the OMS system. The operation of distribution network dispatching is a complex and precise process, and the instructions in the fixed value application form must be accurate. The three-review system can ensure that the instructions are checked and confirmed many times before they are issued, avoiding dispatching errors caused by wrong instructions. For example, if the fixed value is set improperly, it may cause line overload, short circuit and other faults, affecting the stable operation of the power grid. Through the three-review, errors in the instructions can be discovered and corrected in time to ensure the safety and reliability of distribution network dispatching. There are great safety risks in distribution network dispatching, which mainly come from dispatchers and dispatching equipment. The three-review system can prompt dispatchers to be more cautious and meticulous in the review process and reduce safety risks caused by human factors. At the same time, the three-review can also supervise and manage the use of dispatching equipment to ensure that the equipment is used within the prescribed range and avoid safety accidents caused by equipment problems. The distribution network fixed value setting needs to be accurately calculated and adjusted according to the actual situation. The three-review system can ensure that the fixed value setting in the fixed value application form has been reviewed and discussed many times, and various factors such as line load, equipment capacity, and operating environment are fully considered. Through brainstorming and expert review, the rationality and accuracy of the setting of fixed values ​​can be improved to ensure that the distribution network can remain stable and safe during operation. The dispatching and operation of the distribution network involves high-voltage equipment and complex circuits. If the dispatching errors or improper setting of fixed values ​​are made, it may pose a threat to the life safety of the staff. The three-review system can ensure the accuracy and rationality of the dispatching instructions and the setting of fixed values, thereby reducing the risk of accidents caused by dispatching errors or improper setting of fixed values ​​and ensuring the life safety of the staff.

[0037] The distribution network OMS sends the call setting command to the distribution network OCS through the interface. The setting setting of the distribution network line switch refers to the maximum instantaneous short-circuit current value that the switch can withstand in the power grid environment. This setting is crucial to the safe operation of the power grid. If the setting setting is set too low, it will lead to over-protection and unable to withstand the rated load current, thus affecting the power supply quality. If the setting setting is set too high, it may cause the current to be unable to be cut off in time during a short-circuit fault, thereby threatening the safety of the power grid. The action characteristics of the protection device are usually closely related to its setting setting. By calling the setting setting, it can be ensured that the protection device operates correctly under the set conditions. For example, when a fault occurs in the power grid, the protection device needs to quickly cut off the fault current to prevent the fault from expanding. At this time, the setting setting plays a key role. The power supply quality of the power grid is affected by many factors, among which the rationality of the setting setting is an important aspect. By calling the setting setting and adjusting it, the operation status of the power grid can be optimized and the power supply quality can be improved. In the distribution network management, the management of setting setting is an important link. The set values ​​need to be regularly checked and adjusted to adapt to changes in the load characteristics and line parameters of the power grid. Calling the set values ​​can timely discover problems in the set value settings and make corresponding adjustments to ensure the safe operation of the power grid and the quality of power supply. The load characteristics and line parameters of the power grid will change over time. By calling the set values ​​and analyzing them, these changes can be discovered in time and appropriate measures can be taken to make adjustments, which helps ensure that the power grid can remain stable and safe in a changing environment.

[0038] The distribution network OCS returns the corresponding constant value of the information body to the distribution network OMS.

[0039] Step 3: After the original set value is called, fill in the new set value, review the new set value list, and send the new set value list to the distribution network OMS for execution after the review is passed. According to the execution result, the corresponding feedback strategy is implemented, such as Figure 4 shown.

[0040] The distribution network OMS will receive the set value and automatically fill in the "original value" and fill in the "new set value". In order to ensure the accuracy of the set value setting, improve the standardization of set value management, strengthen the control of power grid security risks, promote inter-departmental collaboration and communication, and adapt to the development and changes of the power grid, a three-review of the new set value list will be conducted.

[0041] The distribution network OMS sends the set value execution request to the distribution network OCS through the interface. The information in the set value execution request form should be accurate, including detailed information such as the name, location, model of the protected object and necessary drawings and materials. The set value setting should meet the operation requirements of the power grid, including speed, sensitivity, selectivity and reliability. The set value setting should ensure the safe operation of the power grid and avoid causing new safety risks. The set value execution request form should comply with the requirements of relevant laws, regulations and regulations.

[0042] The distribution network OCS sets or adjusts the protection settings in the distribution network according to the requirements in the request form and returns the execution results to the distribution network OMS.

[0043] If the execution result is successful, a set value check is performed. The distribution network OMS compares the actual operating set value with the set value on the new set value list. If they are consistent, the set value modification is successful. If they are inconsistent, the inconsistent set value items will be resent to the distribution network OCS for execution.

[0044] After all the setting orders are successfully executed, the distribution network OMS sends the command to call the setting to the distribution network OCS through the interface again. When setting the protection setting for the first time, the setting may be inaccurate due to parameter calculation errors, changes in on-site conditions, or equipment status updates. To ensure the safe operation of the power grid, it is necessary to call the setting again for verification and adjustment. The operating status of the power grid may change due to various factors such as load changes, weather conditions, and equipment failures. When the operating status of the power grid changes significantly, it may be necessary to adjust the protection setting to adapt to the new operating conditions. When maintaining or overhauling the distribution network automation equipment, it may be necessary to call the setting again to confirm whether the protection setting of the equipment is correct. If the equipment has been upgraded or modified, it may also be necessary to reset the protection setting. When a power grid fails, in order to quickly locate and isolate the fault area, it may be necessary to call the setting to check the action of the protection device. After the fault is restored, it is also necessary to call the setting again to ensure that the protection device can respond correctly to future faults. With the development of the power grid and technological progress, it may be necessary to continuously optimize and adjust the protection setting to improve the safety and reliability of the power grid. Calling the setting again can implement these optimization and adjustment measures.

[0045] The distribution network OMS compares the fixed value returned by the distribution network OCS with the "new fixed value". After the detection is consistent, the fixed value list is archived. If the detection is inconsistent, the system automatically detects twice. If there is still inconsistency after automatic detection, you can manually choose to re-detect or re-execute the fixed value. The existing manual fixed value comparison has low work efficiency and a high probability of error in comparison. We propose an automatic comparison method based on machine learning algorithm to pre-process the distribution network fixed value data. This includes steps such as data cleaning, missing value filling, and outlier processing to ensure the quality and consistency of the input data, and extract features related to the distribution network fixed value from the pre-processed data. These features may include electrical parameters such as current, voltage, and power, as well as auxiliary information such as equipment type and operating status. The model is trained through machine learning algorithms. During the training process, the known distribution network fixed value data is used as the training set. The prediction accuracy of the model is improved by continuously adjusting the model parameters. The trained model can be used to automatically compare the new distribution network fixed value. By inputting the new fixed value into the model, the model will output a prediction result, which can be compared with the actual fixed value to determine whether there is a difference.

[0046] If the execution result is execution failure, it will be sent to the distribution network OCS for execution again or transferred to the on-site execution. After all set value items are executed, the distribution network OMS archives the set value list and sends the archived information to the main network OCS, the main network OCS closed-loop set value list.

[0047] Example 2, reference Figure 5 , which is the second embodiment of the present invention, and is different from the first embodiment in that: a system for a remote operation and maintenance collaborative control method for distribution automation terminals includes adding distribution network fixed value item maintenance, fixed value templates, protection fixed value modification applications, and distribution automation terminal remote operation and maintenance modules in the distribution network OMS system deployed in the provincial dispatching three districts, interacting with the distribution network OCS system deployed in the local dispatching (the local dispatching three districts part) and the main network OMS deployed in the provincial dispatching three districts to realize remote access and modification of distribution terminal protection fixed values, such as Figure 5 shown.

[0048] Specifically, it includes a set value item maintenance module, a set value template module, a protection set value modification application module, a set value order execution module and a distribution automation terminal remote operation and maintenance module; the set value item maintenance module is used to synchronize the set value order information of the main network OMS system and the terminal information of the distribution network OCS; the set value template module creates a set value application form based on the set value order number in the set value order information; the protection set value modification application module is used to apply for set values, call the original set values ​​and fill in new set values; the set value order execution module sends the new set value order to the distribution network OMS for execution, and synchronizes the execution information; the distribution automation terminal remote operation and maintenance module is used to archive the set value order based on the distribution network OMS after all set value items are completed, and send the archived information to the main network OCS, and the main network OCS closed-loop set value order.
