[0042] Please refer to Figure 1 , an embodiment of the present invention provides a feeder automation test system, including:

[0043] The cloud and the edge side;

[0044] The cloud includes a test master station;

[0045] The edge side includes several feeder automation testers;

[0046] Each feeder automation tester is connected to the cloud;

[0047] The edge side is connected to the device under test, and the device under test includes a relay protection device and several distribution terminals;

[0048] The test master station includes a display layer, a model layer, and an interface layer; the display layer is used to display the simulated action switches of the distribution network grid; the model layer is used to generate the effective values of voltage and current required for testing and transmit the effective values of voltage and current to the interface layer; the interface layer is used to output the effective values of voltage and current to the edge side and receive the switch state information of the simulated circuit breaker sent by the edge side;

[0049] The feeder automation tester includes a waveform generation module and a simulated circuit breaker module. The waveform generation module is used to receive the effective values of voltage and current sent by the interface layer, generate waveform analog quantities from the effective values of voltage and current to the on-site distribution terminal, so that the on-site distribution terminal generates corresponding switch quantities according to the waveform analog quantities and sends them to the simulated circuit breaker module;

[0050] The simulated circuit breaker module is used to generate the switch state information of the simulated circuit breaker according to the corresponding switch quantity and send the switch state information of the simulated circuit breaker to the interface layer.

[0051] In the embodiment of the present invention, the cloud also includes a cluster management node, and the cluster management node is used to construct, update, and control the waveform generation module and the simulated circuit breaker module in the feeder automation tester.

[0052] The embodiment of the present invention is based on the cloud-edge collaboration technology and constructs a feeder automation test system by combining the Kubernetes cluster management technology and the Docker container technology.

[0053] Please refer to Figure 2 , it should be noted that the Docker containerization technology and the K8s container cluster management technology can realize efficient and reliable dynamic management of various services in the cloud-edge collaboration architecture. Kubernetes maintains and manages the Docker container cluster by following the master-slave architecture and provides services such as automated deployment, load balancing, resource scheduling, and high availability for it. Docker is an open-source application container engine that can package the application program code and its running dependency environment into a portable container and then publish it to run on the machine. The Kubernetes system divides the nodes into two roles: Master nodes and Node nodes. The Master node is the control node responsible for the management and control of the entire Kubernetes cluster, and the Node node is the working node responsible for running the containerized applications deployed in it. The architecture of the Kubernetes cluster management system is as Figure 2 shown, and the meanings and functions of the key components in the cluster are shown in Table 1.

[0054] Table 1 Meanings and Functions of Key Kubernetes Components

[0055]

[0056]

[0057] The cluster management node is the K8s - master management node, mainly used for the construction, update, control, and scheduling of edge - side Node worker nodes and their internal Pods. At the same time, the cloud contains the feeder automation test master - station Node worker node. In the test master - station Node, the model - layer Pod can generate the effective values of voltage and current required for testing, can provide virtual terminals and virtual relay protection devices for feeder automation testing, can realize the orderly interaction and collaborative promotion among various components of feeder automation testing through the collaborative control module, and can judge the correctness of the feeder automation test logic. The database can store the data of the test master - station itself and the interactive data during the test process; the interface - layer Pod can output the effective values of voltage and current required for feeder automation testing and receive the switch - state information of the analog circuit breaker at the same time; the display - layer Pod can build the distribution network grid and realize the dynamic display function of switch position change, and has the management function during the feeder automation test process. The edge - side mainly includes the tester Node worker node. Among them, the waveform - generation module Pod is used to receive the effective values of voltage and current from the test master - station and generate continuous analog voltage and current waveforms to output to the on - site distribution terminal. The analog - breaker module Pod is used to receive the digital quantity from the on - site distribution terminal and act, and then output the switch - position change information to the test master - station and the on - site distribution terminal; it also includes a management module, and the management - module Pod can monitor and manage the real - time operation of the tester; it also includes a database module, and the database - module Pod can store the data interaction of the tester.

[0058] In the embodiments of the present invention, the functions of the test master - station and the feeder automation tester are divided into different modules, such as the display layer, the model layer, the interface layer, the waveform - generation module, and the analog - breaker module. The modular design helps to maintain and upgrade each part of the system, and can effectively improve the scalability and flexibility of the feeder automation test system, and further can effectively improve the reliability and accuracy of the feeder automation test.

[0059] Furthermore, in the embodiments of the present invention, the analog - breaker module generates the switch - state information of the analog circuit breaker according to the corresponding digital quantity generated by the on - site distribution terminal and feeds it back to the interface layer, realizing the closed - loop control of the test signal, and can further improve the reliability and accuracy of the feeder automation test.

[0060] In one embodiment, the model layer is also used to judge the correctness of the feeder automation test logic for the switch - state information of the analog circuit breaker sent by the interface layer.

[0061] In one embodiment, the display layer is used to display the action switches of the distribution network grid simulation, including:

[0062] Receiving the switch status information sent by the model layer when the feeder automation test logic for determining the switch status information of the simulated circuit breaker is correct, converting the switch status information into the action switches of the distribution network grid simulation and displaying them.

[0063] In one embodiment, the interface layer is used to output the effective values of voltage and current to the edge side, including:

[0064] The interface layer is used to send the effective values of voltage and current to the waveform generation module on the edge side based on the Flannel d communication method.

[0065] Please refer to Figure 3 , in the embodiment of the present invention, in the feeder automation test, there is a large amount of information and data interaction, such as the effective values of voltage and current data, waveform analog data, switch quantities, and action information, etc. The embodiment of the present invention assumes that all Pods are in a flat network space that can be directly connected, and the core of its communication mode is to associate the IP addresses of different components to achieve communication and access between components.

[0066] For the communication between different containers in the same Pod, it is implemented by sharing the network protocol stack of the Pause container; for the communication between different Pods in the same Node node, the Docker0 bridge assigns sub-IP addresses to different Pods to achieve communication between different Pods; for the communication between Pods in different Node nodes, it is implemented based on the Flannel d communication method. Taking the example of the interface layer Pod of the test master station node sending waveform information to the waveform generation module Pod of the tester node, first, the interface layer Pod sends the waveform data packet, its own IP address, and the target IP address to the Docker0 bridge. Docker0 grabs the data information through the hook function and continues to send it to the Flannel 0 bridge. The Flannel 0 bridge will determine the specific forwarding path through the routing table information in Flannel d. Subsequently, Flannel d performs secondary encapsulation on the data, and then sends it to the target tester node IP through the switch. After receiving the data packet, the tester node parses it through Flannel d and obtains the IP of the specific target Pod, and then sends the waveform data to the tester waveform generation Pod through Flannel 0 and Docker0, realizing the communication between Pods in different Node nodes during the feeder automation test.

[0067] Please refer to Figure 4, in one embodiment, during the feeder automation test process, the test master station has data such as the effective values of voltage and current, the topological change data of the distribution network grid, and the test process data, etc. The tester has data such as the action data of the simulated circuit breaker, the voltage and current waveform data, etc. In the embodiment of the present invention, Etcd is used to store all the configuration data and status information in the feeder automation test system cluster, and the persistent volume (PV, Persist Volume) and the persistent volume claim (PVC, Persist Volume Claim) are used to achieve the persistent storage of the cluster data. PV is a storage volume plugin, which is the external interface of the specific storage (NFS, MFS). PVC is the storage request proposed by the user. PVC consumes the PV resources by applying for memory from the PV. The binding between PV and PVC is exclusive, and the two are in a one-to-one mapping, and will not change with the deletion, restart, or update of the Pod. For example, when the node where the model layer Pod is located fails, the system migrates it to the standby node for operation, and at the same time, its internal data will not disappear, and its binding relationship still exists.

[0068] Please refer to Figure 5 , in one embodiment, to improve the high availability of the feeder automation test system architecture, the present invention privately relies on the Kubernetes cluster to establish a high-availability architecture of Keepalived + 3 HAProxy load balancers + 3 Master nodes + 3 test master station Node nodes + N tester Node nodes.

[0069] In the high-availability architecture, both the load balancer HAProxy and the Master node adopt a primary and multiple standby operation mode. The load balancer HAProxy uses the Keepalived + virtual IP (VIP) method to achieve the high availability of the load balancing. When the primary HAProxy fails, Keepalived will migrate the virtual IP address to the standby HAProxy to quickly restore the load balancing service. For the Master node and the test master station, when the Master1 node in server 1 is in the running state, the test master station 1 in server 1 is correspondingly started. When the Master1 node or the test master station 1 is unavailable due to an exception, the standby Master2 node and the test master station 2 are called through HAProxy to continue running, realizing the high availability of the Master node and the test master station.

[0070] The high availability of Node nodes and Pods is achieved by the Kubernetes system itself. For example, for the test master station, two model layer Pods with the same functions can be established. When one of the model layer Pods becomes unavailable, the standby model layer Pod can be automatically enabled to continue the feeder automation test task. The cluster can add standby Node nodes and Pods at any time to ensure the high availability of the feeder automation test system.

[0074] Furthermore, in the embodiments of the present invention, the simulated circuit breaker module generates the switch state information of the simulated circuit breaker according to the corresponding switch quantity generated by the on-site distribution terminal and feeds it back to the interface layer, realizing the closed-loop control of the test signal, and can further improve the reliability and accuracy of the feeder automation test.
