Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power supply supervision, and particularly relates to a distributed power supply operation quality supervision system based on 5G. BACKGROUND

[0002] In the power grid control technology, the investment cost and maintenance cost of the centralized control mode are relatively high, and when the master station fails, the whole control system will be paralyzed, the robustness is poor, and the time spent on information processing is relatively long during the failure. With the development of communication technology and the improvement of intelligent power distribution equipment manufacturing process, the existing power grid power supply control more and more selects the distributed control mode.

[0003] The existing distributed power supply control mode is no longer limited to wired network connection due to the continuous progress of 5G technology, and the low delay of 5G can gradually meet the requirements of distributed control. However, the existing distributed power supply still does not have a quick and effective recovery means for the load under the power supply when the local power supply fails. Therefore, the present application provides a distributed power supply operation quality supervision system based on 5G to solve the problem that the load under the power supply cannot be quickly and effectively recovered in the distributed power supply system, thereby improving the operation quality of the power supply system. SUMMARY

[0004] The present application provides a distributed power supply operation quality supervision system based on 5G to solve the problem that the load under the power supply cannot be quickly and effectively recovered in the distributed power supply system, thereby improving the operation quality of the power supply system.

[0005] A distributed power supply operation quality supervision system based on 5G, comprising: a 5G base station, a receiving module and a node module; the number of node modules is several, which are connected to the 5G base station through the receiving module and call power between other node modules.

[0006] As an improvement of the above technical solution, the node module includes an isolation module for isolating and closing the power supply of the fault node module.

[0007] As an improvement of the above technical solution, the node module further includes a borrowing module for borrowing the spare power of the power supply of the remaining node modules to quickly supply power to the fault node module.

[0008] As an improvement of the above technical solution, the node module further includes a judgment module for selecting a suitable distributed power supply to supply power to the node module after the power supply of the borrowing module is completed.

[0009] As an improvement of the above technical solution, the node module further includes a detection module for detecting whether the power supply of the node module is supplied to the remaining node modules, and marking the node module that supplies power;

[0010] The borrowing module supplies power to all marked node modules.

[0011] As an improvement of the above technical solution, the node module further comprises a supplement module for supplementally supplying power to the node module whose power demand exceeds its own power supply amount by borrowing other distributed power sources.

[0012] A 5G-based distributed power source operation quality supervision system, and the specific working method is as follows:

[0013] Step 1, the isolation module judges whether the power supply of the node module with insufficient power supply is faulty, and performs isolation and closed processing on the faulty power supply.

[0014] Step 2, the detection module detects all node modules supplied by the node module with faulty power supply, and marks all the node modules;

[0015] Step 3, the borrowing module borrows other distributed power sources with power supply capacity to quickly supply power to the marked node modules;

[0016] Step 4, the judgment module optimizes the power supply of the node module after the power supply of the borrowing module is completed.

[0017] As an improvement of the above technical solution, after step 4, step 5 is further included, specifically: the supplement module supplementally supplies power to the node module whose power demand exceeds its own power supply amount by borrowing other distributed power sources.

[0018] As an improvement of the above technical solution, in step 4, the specific steps are as follows:

[0019] When any one of the plurality of distributed power source modules can provide all power demands of the faulty node module, the judgment module selects the distributed power source that can provide all power demands of the faulty node module to supply power to the faulty node module;

[0020] When the total power supply amount of the plurality of distributed power source modules can meet all power demands of the faulty node module, the judgment module selects the plurality of distributed power sources that meet all power demands of the faulty node module to supply power to the faulty node module;

[0021] When the total power supply amount of the plurality of distributed power source modules cannot meet all power demands of the faulty node module, the judgment module determines the node that can be restored according to the load priority and the principle of restoring the most load of the node module.

[0022] As an improvement of the above technical solution, the load priority and the principle of restoring the most load can be expressed as follows:

[0023] F(i,C) = max(F(i-1,C),v(i)+F(i-1,C-w(i)))

[0024] In the formula, C is the available margin of the node module distributed power supply, n is the number of modules to be restored of the node module, v is the node weight, and w is the node capacity.

[0025] Compared with the prior art, the technical effects of the present application are as follows:

[0026] The distributed power supply operation quality monitoring system based on 5G can improve the overall power supply operation quality in the system and make the power load operation more smooth by the mutual communication between the internal node modules and the use of the distributed power supply of each other to meet the power supply demand.

[0031] In order to make the purpose, technical scheme and advantages of the present application clearer and more apparent, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0032] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can be present.

[0033] As Figure 1As shown, the 5G-based distributed power supply operation quality monitoring system can realize distributed control of the load power supply based on the peer-to-peer communication strategy of 5G communication, and each load can send signals to adjacent loads according to its own node information and through peer-to-peer communication, so as to realize collaborative power supply and improve the overall power supply operation quality. Specifically, it includes a 5G base station 10, a receiving module 20, and a node module 30. The node module 30 can be regarded as a communication node in the power grid system communication network, for example, it can be various types of intelligent load terminals. The positions of the plurality of communication nodes are equal, and information interworking can be realized to form a peer-to-peer communication network. The node module 30 accesses the 5G base station 10 through the receiving module 20, receives and sends data through the 5G core network, so as to complete the information interaction between the node modules 30. The node module 30 and the receiving module 20 are installed in the same ring network cabinet, and when there are a plurality of node modules 30 in a local power distribution system, each node module 30 needs to be equipped with a receiving module 20 to form a peer-to-peer communication network. In this way, through the mutual communication between the node modules 30, the respective load power supply can be called for power distribution management, and when a node module 30 is powered off and cannot be restored, the load power supply of the nearby node module 30 can be called through communication with the nearby node module 30 to supply power, thereby improving the power supply operation quality of the overall system.

[0034] As a further optimization improvement, as shown in Figure 2 、 Figure 3 As shown above, the above only introduces that the node module 30 can exchange information between each other through the receiving module 20 and the 5G base station 10 to share the use of power supply. However, when sharing the use of power supply, it is possible that when other node modules 30 supply power, the load power supply of the node module 30 itself may suddenly recover power supply at some time, causing the node module 30 to no longer borrow the distributed power supply, thereby possibly causing frequent borrowing of the distributed power supply. Therefore, the node module 30 includes an isolation module 31, which isolates and closes the power supply of the node module 30 when the power supply of the node module 30 is abnormal, and interacts with the remaining node modules 30 to request to borrow power. In this way, the abnormal power supply will not affect the subsequent power supply, and only when the staff checks and repairs are completed, the isolation module 31 is removed from the isolation and closure of the power supply, so that the power supply can be performed.

[0035] As a further optimization improvement, as shown in Figure 2 、 Figure 3As shown, when the distributed power sources borrow power from each other, multiple distributed power sources can also supply power to several fault node modules 30 at the same time. At this time, since the multiple distributed power sources can have different power supply capacities, in order to better adjust the power supply relationship, the node module 30 also includes a judgment module 32 for selecting a suitable distributed power source to supply power to the fault node module 30. It mainly includes the following three cases:

[0036] 1. Any one of the multiple distributed power source modules can provide all the power needs of the fault node module 30;

[0037] 2. The total power supply capacity of the multiple distributed power source modules can meet all the power needs of the fault node module 30;

[0038] 3. The total power supply capacity of the multiple distributed power source modules cannot meet all the power needs of the fault node module 30;

[0039] When in case 1, the judgment module 32 selects a distributed power source that can provide all the power needs of the fault node module 30 to supply power to the fault node module 30;

[0040] When in case 2, the judgment module 32 selects multiple distributed power sources that can meet all the power needs of the fault node module 30 to supply power to the fault node module 30;

[0041] When in case 3, the judgment module 32 determines the nodes that can be restored according to the load priority of the node module 30 and the principle of restoring the most load, and restores the high-priority load first with the limited available margin, while restoring as many loads as possible under this premise. Specifically, assuming that the available margin of the distributed power source of the node module 30 is C, the number of node modules 30 to be restored is n, the node weight is v, and the node capacity is w, and the total weight of the restored nodes after restoration is the restoration target. When calculating to node n, the total weight at this time can be represented as F(n-1, C), if node n is selected to be restored, the total weight becomes v n +F(n-1, C-w n ), and the maximum of the two weight values is the final restoration scheme, so the recurrence formula of this problem can be represented as follows:

[0042] F(i, C) = max(F(i-1, C), v(i) + F(i-1, C-w(i))) Formula 1

[0043] As a further optimization improvement, such as Figure 2 , Figure 3As shown, in order to better guarantee the operation quality of the power supply, the faster the repair of the fault node 30 is, the better. The node module 30 further comprises a borrowing module 33 for quickly borrowing the spare power of the power supply of the remaining node modules 30, so as to meet the power demand of the fault node module 30 as soon as possible and restore power supply to the fault node module 30. When the borrowing module 33 completes the borrowing of the distributed power supply to restore power supply to the fault node module 30, the judgment module 32 optimizes and manages the distributed power supply borrowed by the fault node module 30, and selects appropriate distributed power supply to supply power to the fault node module 30.

[0044] As a further optimization improvement, as known from the above, in the distributed power supply management system, the distributed power supply of the node module 30 itself can not only supply power to the node itself, but also can supply power to additional nodes. Therefore, as shown in Figure 2 、 Figure 3 When the power supply of the node module 30 itself fails, it can not only affect the node module 30 itself, but also affect other node modules 30. Based on this, the node module 30 further comprises a detection module 34 for detecting whether the power supply of the node module 30 itself supplies power to other node modules 30 and marking the node modules 30 that supply power. Therefore, when the power supply of the node module 30 fails, the node modules 30 marked by the detection module 34 all communicate with other node modules 30 through the borrowing module 33 to request borrowing of the distributed power supply. Thus, the power supply of the internal nodes of the whole system can be more smooth and stable.

[0045] As a further optimization improvement, the above relates to the failure of the power supply of the node module 30 to effectively supply power to the node itself. In actual production, the node module 30 can also increase the power demand at a certain time period. In order to meet such conditions, as shown in Figure 2 、 Figure 3 The node module 30 further comprises a supplement module 35 for borrowing other distributed power supply to supply power to the node module 30 whose power demand exceeds the supply of the power supply itself. When the isolation module 31 is not enabled, but the power demand of the node module 30 is insufficient, the supplement module 35 communicates with other node modules 30 through the receiving module 20 to call the power supply of other node modules 30.

[0046] The receiving module 20 in the present application can be understood in the scope of the prior art, which is an information transceiving module CPE for 5G communication in the present system, and will not be described here.

[0047] In summary, the distributed power supply operation quality monitoring system based on 5G can meet the power demand by borrowing the distributed power supply of each other through the mutual communication between the internal node modules 30, so as to improve the overall power supply operation quality in the system and make the power load operation more smooth.

[0048] It has to be noted that, in the present document, the terms "first", "second", etc. merely serve to identify a subject or action, without necessarily requiring or implying any such actual relationship or order between such subjects or actions. Moreover, the terms "comprising", "containing", or any other similar term are intended to encompass non-exclusive inclusions, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a", "contains... a", or "includes... a" does not, without more constraints, exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0049] The foregoing is merely illustrative of the principles of the application, and various modifications can be made by those skilled in the art without departing from the scope and spirit of the application.
