[0020] In an embodiment, before the step of determining a master node from the nodes of the ring main units adjacent to the node where the fault occurs when a fault of any node where a ring main unit is located in the ring network power supply system is monitored, the method further includes:

[0021] The fault of the node where the ring main unit is located includes an operating fault and a security fault;

[0022] monitoring each node of the ring network power supply system and a path between each node of the ring network power supply system to monitor an operating fault of each node of the ring network power supply system;

The node location is determined, and other adjacent nodes are identified. To ensure a reasonable power restoration process, a primary node and a secondary node are selected from the adjacent nodes. Adjustment strategies are generated through the primary and secondary nodes respectively.

[0041] It should be understood that the specific embodiments described herein are merely exemplary and do not limit the present application.

[0042] Reference Figure 1 , Figure 1 FIG. 1 is a flowchart of a first embodiment of a control method for a ring main unit according to the present application.

[0043] In the first embodiment, the control method for the ring main unit includes the following steps:

[0044] S10, when a fault is detected at a node where any ring main unit of the ring network power supply system is located, determining a master node from ring main unit nodes adjacent to the node where the fault occurs, and taking the remaining adjacent ring main unit nodes as slave nodes;

[0045] It should be understood that the ring network power supply system refers to a power system including multiple ring main units. Specifically, typical application scenarios of multiple ring main units include the following: urban grid power distribution network features multiple power sources (substations, distributed energy sources) interconnected, high load density, and power supply reliability requirements greater than or equal to 99.99%. The number of ring main units used in this scenario is usually 10 to 20, forming a multi-closed loop network. Through networking, the two main substations each output a return line, forming a double ring through ring main units, mainly adopting a petal type structure, and 3 to 4 ring networks converge at the core node (such as an important user entrance). The technology realizes intelligent load switching. When a certain substation is overloaded, part of the load is automatically transferred to another substation ring network. In addition, it also includes the following: industrial park multi-power backup scenario features important industrial loads (such as semiconductor factories) requiring dual power supply and emergency power backup. The number of ring main units used in this scenario is usually 4 to 6, forming a local double ring network. Through networking, double ray and ring network, two independent power sources radiate power supply, and the end is closed through the ring main unit. The main interface for emergency power supply is reserved in the ring main unit. The technology realizes seamless switching, uses a static transfer switch, and realizes the switching of city power and emergency power supply.

[0046] It should be noted that according to the above description, in the application process of the ring network power supply system, there may be a situation that any node of the ring network cabinet fails, which specifically includes that the ring network cabinet node is maliciously tampered with by external forces, the load of the ring network cabinet node is too high, the ring network cabinet runs abnormally, etc. At this time, it is usually necessary to switch the power supply loop of the ring network cabinet, on the one hand to avoid the ring network cabinet node with a fault, and on the other hand to ensure the normal operation of each ring network cabinet node in the entire ring network power supply system (mainly refers to the load balance, to avoid the influence of high load on the normal working state).

[0047] It should be further pointed out that the ring network power supply system includes power supply loops composed of different ring network cabinets, including the double-ring network loop, the multi-closed loop network loop, etc. involved in the above described process. After the ring network cabinet with a fault in the different ring network loops, the first affected by the faulty ring network cabinet is the adjacent ring network cabinet, among which the downstream power supply ring network cabinet is the most seriously affected by the faulty ring network cabinet, and the upstream or multi-branch ring network cabinet is less affected. However, in order to isolate the faulty ring network cabinet from the ring network power supply system, it is necessary to analyze the operating load and loop communication of the upstream and downstream and multi-branch ring network cabinets adjacent to the faulty ring network cabinet, and select the faulty ring network cabinet from the ring network power supply system to adjust the power supply scheme of the ring network power supply system, that is, the main node and the auxiliary node are both the main reference nodes for generating the power supply scheme.

[0048] Among them, the ring network cabinet node with the largest degree of association between the faulty ring network cabinet node or the most affected ring network cabinet node after the faulty ring network cabinet node is isolated from the ring network power supply system is the main node, and the ring network cabinet node with a slightly lower degree of association between the faulty ring network cabinet node or the slightly weaker ring network cabinet node affected after the faulty ring network cabinet node is isolated from the ring network power supply system is the auxiliary node. Among them, the main node and the auxiliary node are both ring network cabinet nodes adjacent to the faulty ring network cabinet node.

[0049] In an embodiment, when it is monitored that any node of the ring network cabinet in the ring network power supply system fails, the step of determining the main node from the ring network cabinet nodes adjacent to the faulty node includes:

[0050] When it is monitored that any node of the ring network cabinet in the ring network power supply system fails, the branch communication condition before the fault occurs and the load condition of the ring network cabinet node adjacent to the faulty node are determined. According to the branch communication condition and the load condition, the association value between each adjacent ring network cabinet node and the faulty node is determined, and the main node is determined according to the size of the association value.

[0051] It can be understood that in the embodiment, the master node and the secondary node are arranged, and the master node and the secondary node are required to be promoted as a cluster to generate various different adjustment strategies, and the ring network power supply system selects a suitable adjustment strategy as a corresponding power supply adjustment scheme.

[0052] It should be noted that the master node is a node mainly generating an adjustment strategy, and the master node is mainly a node having the greatest degree of association with the node having a fault, and the secondary node is a node having a slightly poor degree of association.

[0053] It can be understood that in the embodiment, the master node and the secondary node are determined by calculating the size of the association value, wherein the size of the association value refers to the size of the degree of association between the ring network cabinet node and the ring network cabinet node having a fault, and the greater the association value, the greater the degree of association.

[0054] In calculating the size of the association value, the connectivity between the ring network power supply system and the ring network cabinet node having a fault and the importance of the branch where the ring network cabinet node is located need to be considered comprehensively, for example, branch 1 is used for power supply of overall lighting in the park, branch 2 is used for power supply of important equipment in the park, and the importance of branch 2 is higher than that of branch 1, so it can be determined that the ring network cabinet node together with the node having a fault in branch 1 is more important, and it is more likely to be a master node, and the greater the corresponding association value.

[0055] The load is also used as a basis for judging a master node and a secondary node, and the higher the load of the ring network cabinet, the greater the corresponding association value.

[0056] S20, obtaining the adjustment strategies generated by the master node and the secondary node respectively, and generating a power supply adjustment scheme of the ring network power supply system after avoiding the node having a fault according to the adjustment strategies;

[0057] It can be understood that the master node and the secondary node will generate an adjustment strategy, and the optimal strategy can be selected from multiple adjustment strategies as a basic scheme for generating a power supply adjustment scheme.

[0058] Specifically, the master node and the secondary node generate an adjustment strategy mainly by using the shortest path search based on the Dijkstra algorithm or superimposing a graph neural network to predict the best power supply.

[0059] In an embodiment, the step of generating the power supply adjustment scheme of the ring network power supply system after avoiding the node having a fault according to the adjustment strategies comprises:

[0060] According to the size of the association value corresponding to the primary node and the secondary node and the preset basic weight value, a node weight value corresponding to the current primary node and secondary node is generated; according to the node weight value, a weight score of each adjustment strategy is determined, and the adjustment strategy with the maximum weight score is determined therefrom; according to the adjustment strategy with the maximum weight score, a power supply adjustment scheme after the ring network power supply system avoids the node that fails is generated.

[0061] It can be understood that the preset basic weight value refers to the basic weight value pre-allocated to the primary node and the secondary node, for example, the primary node 0.1 and the secondary node 0.05, but in this embodiment, the size of the role played by the primary node under different association value sizes also needs to be considered, therefore, the size of the association value corresponding to the primary node and the secondary node is comprehensively considered, and the preset basic weight value is adjusted, for example, the association value of the primary node is much larger than that of the secondary node under the current condition, and the weight value of the primary node should be increased, for example, the basic weight value is adjusted to the primary node 0.2 and the secondary node 0.02.

[0062] It can be understood that the primary node and the secondary node will both generate an adjustment strategy, there are some similar or identical adjustment strategies among them, and such adjustment strategies are screened and classified, and the weight value of the corresponding ring network cabinet node is accumulated to obtain a weight score, and the adjustment strategy with the maximum weight score can be used as a basis to generate a corresponding power supply adjustment scheme.

[0063] In an embodiment, after the step of generating the power supply adjustment scheme after the ring network power supply system avoids the node that fails according to the adjustment strategy with the maximum weight score, the method further comprises:

[0064] According to the preset digital twin model of the ring network power supply system, the running state of each ring network cabinet node in the ring network power supply system after the implementation of the power supply adjustment scheme is simulated and verified; the simulated and verified running state is evaluated, and the node weight value is adjusted according to the evaluation result.

[0065] It can be understood that the preset digital twin model of the ring network power supply system refers to a digital model constructed according to the actual hardware parameters of each ring network cabinet node of the actual ring network power supply system, the connection relationship between each ring network cabinet node and the working environment parameters of each ring network cabinet node. Through the digital model, the running state of the ring network power supply system can be simulated, for example, when A ring network cabinet is under high load, B ring network cabinet and C ring network cabinet will automatically share part of the load of A ring network cabinet to reduce the peak load of each ring network cabinet node in the ring network power supply system.

[0066] In the embodiment, the operation state after the power supply adjustment scheme is implemented is simulated mainly through the digital twin model, on the one hand, whether the power supply adjustment scheme is reasonable can be determined, and on the other hand, the node weight value when the power supply adjustment scheme is generated can be optimized according to the unreasonable power supply adjustment scheme.

[0067] For example, when it is simulated that the power supply adjustment scheme is unreasonable, it can be proved that the adjustment strategy generated by the current master node and the secondary node is not the optimal solution. In addition to the adjustment strategy, the main parameter affecting the final generation of the power supply adjustment scheme also includes the node weight value of the corresponding master node and secondary node. If it is simulated that the adjustment strategy corresponding to the current power supply adjustment scheme is the strategy mainly promoted by the master node, the weight value of the master node is reduced and the weight value of the secondary node is increased. If it is simulated that the adjustment strategy corresponding to the current power supply adjustment scheme is the strategy mainly promoted by multiple secondary nodes, the weight value of the secondary node is reduced and the weight value of the master node is increased.

[0068] S30, according to the power supply adjustment scheme, optimizing the operation parameters of each ring main unit node in the ring network power supply system.

[0069] It can be understood that after the power supply adjustment scheme is determined, the pre-configured circuit breaker, relay and other switching devices in each ring main unit can be controlled by remote control, and the switching of the operation loop of the ring main unit and the adjustment of the load and other operation parameter levels are adjusted, so that each ring main unit node in the ring network power supply system that does not appear a fault executes operation according to the power supply adjustment scheme.

[0070] The embodiment determines the master node from the ring network cabinet nodes adjacent to the node where the fault occurs and takes the remaining adjacent ring network cabinet nodes as the secondary nodes when monitoring that any ring network cabinet node in the ring network power supply system has a fault. The adjustment strategy generated by the master node and the secondary node is obtained, and the power supply adjustment scheme of the ring network power supply system after avoiding the node where the fault occurs is generated according to the adjustment strategy. According to the power supply adjustment scheme, the operating parameters of each ring network cabinet node in the ring network power supply system are optimized. When any ring network cabinet in the ring network power supply system has a fault, the automatic recovery mechanism is triggered to determine the node position of the ring network cabinet where the fault occurs in the ring network power supply system and determine the other nodes adjacent to the node. In order to ensure that the subsequent power supply recovery action is reasonably completed, the master node and the secondary node are selected from the adjacent other nodes, and the adjustment strategy is generated through the master node and the secondary node respectively. The final power supply adjustment scheme of the ring network power supply system after avoiding the node where the fault occurs is generated by comprehensively considering the adjustment strategies of each node. Therefore, the ring network power supply system can control the operating parameters of each ring network cabinet in the system according to the power supply adjustment scheme to optimize the load and connection relationship of each ring network cabinet node, thereby ensuring the self-recovery of the ring network power supply system, avoiding the traditional mechanical switch and fixed protection strategy, and improving the recovery speed of the remaining ring network cabinets in the ring network power supply system except the fault ring network cabinet.

[0071] As shown in Figure 2 The method further includes the following steps in the second embodiment of the ring network cabinet control method based on the first embodiment:

[0072] The fault occurring at any ring network cabinet node includes a running fault and a security fault. The running fault refers to an abnormality in the running of the ring network cabinet in the ring network power supply system, for example, load abnormality, running environment abnormality, ring network cabinet hardware fault, etc. The security fault refers to the abnormality of the communication consensus identity of the node where the ring network cabinet is located, including sending error alarm information or other instructions, communication level security abnormality caused by malicious tampering by external forces, etc.

[0073] S110, monitoring each ring network cabinet node in the ring network power supply system and the path between each ring network cabinet node to monitor the running fault of each ring network cabinet node in the ring network power supply system;

[0074] It can be understood that for the possible running fault in the ring network power supply system, each ring network cabinet node and the path between each ring network cabinet node need to be monitored to determine whether each ring network cabinet node in the ring network power supply system has a running fault through load-related data.

[0075] Specifically, for typical cable path faults, such as phase-to-phase short circuit, single-phase grounding, and broken wire, the diagnosing techniques that can be used are traveling wave positioning, specifically by injecting high-frequency pulses to measure the time difference of reflected waves, or by impedance spectrum analysis to scan the impedance characteristics in the frequency range of 1 Hz to 1 MHz to identify partial discharge points. For example, taking the short circuit between ring network cabinets A and B as an example, the detection of short circuit current by cabinet A and the detection of reverse current by cabinet B can determine that the fault is in the A-to-B section.

[0076] S120, selecting any node in the ring network power supply system as an initial verification node, and starting to verify the identity of each node in the ring network power supply system in a heartbeat mechanism timing manner to determine the security failure of each ring network cabinet node in the ring network power supply system.

[0077] It can be understood that the ring network power supply system includes multiple ring network cabinets, and there is a certain communication link between the ring network cabinets. For example, if the upstream ring network cabinet alarms due to excessively high peak load, it needs to coordinate the distribution of part of the load to other ring network cabinet nodes. If any ring network cabinet appears abnormal, is hijacked by external forces, or has unstable communication during this process, the intelligent control scheme of ring network cabinet load distribution cannot be realized, because the safety of each ring network cabinet node needs to be ensured.

[0078] In this embodiment, a security verification scheme is mainly used to verify the identity information of each ring network cabinet node in a heartbeat mechanism timing manner. Each time the verification is performed, any node in the ring network power supply system is selected as an initial verification node, and then the adjacent ring network cabinet nodes are sequentially verified from the initial verification node. After all the ring network cabinet nodes in the ring network power supply system are verified, the information after the identity verification of each ring network cabinet is returned to the initial verification node, and the information is judged by the initial verification node to determine whether there is a security failure of the ring network cabinet node, that is, whether there is an identity abnormality of the ring network cabinet node.

[0079] It should be noted that the verification is mainly performed in a random single loop manner in the heartbeat mechanism. Any ring network cabinet node in the ring network power supply system has only one verification opportunity. Each ring network cabinet node in the ring network power supply system pre-stores the corresponding information of all nodes in the ring network power supply system and sets a secret key for identity verification. The corresponding information of each node is accumulated and transmitted by the secret key. For example, the information a of the A ring network cabinet is transmitted to the B ring network cabinet, and the information a and the information b of the B ring network cabinet are transmitted to the next ring network cabinet. The information for identity verification is transmitted from the initial verification node to the initial verification node, and the information after the accumulation is judged by the initial verification node to determine whether there is a disconnected ring network cabinet node or an abnormal feedback node.

[0080] In an embodiment, after the step of optimizing the operation parameters of each ring main unit node in the ring network power supply system according to the power supply adjustment scheme, the method further comprises:

[0081] According to the optimized connection relationship of each ring main unit node in the ring network power supply system, an instant key is generated and broadcast to each ring main unit node in the ring network power supply system, so that each ring main unit node verifies the identity of each other according to the heartbeat mechanism and the instant key and the node data of each ring main unit node.

[0082] It can be understood that the connection relationship of each ring main unit node in the optimized ring network power supply system is changed, in order to further ensure the security of each ring main unit node in the optimized ring network power supply system, the connection relationship is converted into actual digital information, and a corresponding instant key is generated, for example, the ring main unit A and the ring main unit B have a connection relationship, the ring main unit B and the ring main unit D have a connection relationship, and the ring main unit B and the ring main unit C are disconnected, and the corresponding digital information a1001b1001d1002c can be generated.

[0083] In this embodiment, the instant key can be used as one of the information for verifying the identity status of each ring main unit node in the heartbeat mechanism, that is, the instant key and the node data of each ring main unit node are used as the required superimposed information, and are sequentially transmitted between nodes and finally verified in the initial verification node.

[0084] In this embodiment, the connection relationship between each ring main unit node in the ring network power supply system and each ring main unit node is monitored to monitor the operation failure of each ring main unit node in the ring network power supply system, any node in the ring network power supply system is selected as an initial verification node, and the identity of each other is verified in the heartbeat mechanism to determine the security failure of each ring main unit node in the ring network power supply system, so that the physical verification is performed to monitor the connection relationship between each ring main unit node in the ring network power supply system and each ring main unit node, to ensure that the operation failure of each ring main unit node in the normal operation is monitored, to avoid the monitoring delay caused by the abnormal situation of each ring main unit node, and the security verification of the identity information of each ring main unit node in the ring network power supply system is realized by the heartbeat mechanism, to avoid the security failure of each ring main unit node.

[0085] In addition, the embodiment of the application also provides a ring main unit control device, referring to Figure 3 , the ring main unit control device comprises:

[0086] The determining module 10 is configured to determine a master node from the ring cabinet nodes adjacent to the failed node and take the remaining adjacent ring cabinet nodes as slave nodes when it is monitored that any ring cabinet node in the ring network power supply system fails;

[0087] The generating module 20 is configured to acquire the adjustment strategies generated by the master node and the slave nodes respectively, and generate a power supply adjustment scheme for the ring network power supply system to avoid the failed node according to the adjustment strategies;

[0088] The control module 30 is configured to optimize the operation parameters of the ring cabinet nodes in the ring network power supply system according to the power supply adjustment scheme.

[0089] The embodiment determines a master node from the ring cabinet nodes adjacent to the failed node and takes the remaining adjacent ring cabinet nodes as slave nodes when it is monitored that any ring cabinet node in the ring network power supply system fails, acquires the adjustment strategies generated by the master node and the slave nodes respectively, and generates a power supply adjustment scheme for the ring network power supply system to avoid the failed node according to the adjustment strategies, and optimizes the operation parameters of the ring cabinet nodes in the ring network power supply system according to the power supply adjustment scheme, that is, when any ring cabinet in the ring network power supply system fails, an automatic recovery mechanism is triggered, the node position of the failed ring cabinet in the ring network power supply system is determined, and other nodes adjacent to the node are determined, in order to ensure that the power supply recovery action is reasonably completed subsequently, a master node and a slave node are selected from the adjacent other nodes, and adjustment strategies are generated through the master node and the slave node respectively, and a final power supply adjustment scheme for the ring network power supply system to avoid the failed node is generated by comprehensively considering the adjustment strategies of the nodes, so that the ring network power supply system can control the operation parameters of the ring cabinets in the system according to the power supply adjustment scheme, to optimize the load and connection relationship of the ring cabinet nodes, and thus the self-recovery power supply of the ring network power supply system is ensured, the traditional mechanical switch and fixed protection strategy are avoided, and the recovery speed of the remaining ring cabinets in the ring network power supply system except the failed ring cabinet is improved.

[0090] It should be noted that each module in the device can be used to realize each step in the above method, and the corresponding technical effects are achieved, which will not be described here in detail.
