[0002] Distribution networks directly serve users and permeate all aspects of social production and daily life. The quality and reliability of power supply from distribution networks are directly related to the power quality for users. Distribution automation is based on the primary network structure and equipment of distribution networks, comprehensively utilizes computer, information, and communication technologies, and integrates information with relevant application systems to achieve the detection, control, and rapid fault isolation of distribution networks, thereby improving power supply reliability, power quality, and enhancing the efficiency and effectiveness of power grid operation.

[0003] Feeder automation (FA) is one of the important functions of distribution network automation systems. It uses automated devices or systems to monitor the operation of distribution lines in real time, detect line faults in a timely manner, locate and isolate faulty areas, and restore power supply to non-faulty areas.

[0004] Currently, feeder automation function testing of the distribution network is mainly conducted using the distribution master station. Because the structure of the distribution network frequently changes, upgrades and maintenance of the distribution master station are often required to enable feeder automation testing. However, the complex structure of the distribution master station makes upgrades and maintenance costly, resulting in high costs for feeder automation function testing of the distribution network. Summary of the Invention

[0005] In view of the above, embodiments of this application provide a method for testing the automated functions of a feeder, as well as a testing apparatus, device, and storage medium, to overcome the problems of the prior art.

[0006] In a first aspect, embodiments of this application provide a method for testing the function of a feeder automation system, applied to an internal communication module in a power distribution terminal device. The power distribution terminal device further includes a management process module connected to the internal communication module. The management process module is configured with a master station simulation model corresponding to a power distribution master station. The power distribution master station is used to connect to the internal communication module and form a power distribution network with the power distribution terminal device. The method for testing the function of the feeder automation system includes: The preset communication protocol of the power distribution master station is obtained, and the preset communication protocol is configured for the internal communication module. The management process module is configured with the preset communication protocol. Based on the preset communication protocol, a link establishment request is sent to the management process module, so that the management process module establishes a link connection with the internal communication module according to the link establishment request and the preset communication protocol, and sends a link establishment confirmation message to the internal communication module based on the preset communication protocol. In response to the link establishment confirmation message returned by the management process module, point table information is sent to the management process module based on the preset communication protocol, so that the management process module performs feeder automation function testing on the distribution network based on the master station simulation model and the point table information, obtains the test results, and sends the test results to the internal communication module based on the preset communication protocol. The point table information is obtained based on the interval equipment reported by the interval equipment connected to the internal communication module.

The verification result includes a first verification result indicating that the interval device has the conditions to perform the remote control operation, or a second verification result indicating that the interval device does not have the conditions to perform the remote control operation. Upon receiving the first verification result, it is determined that the interval device has the conditions to perform the remote control operation; If neither the first verification result nor the second verification result is received, or if the second verification result is received, it is determined that the interval device does not meet the conditions for performing the remote control operation.

The management process module is configured with the preset communication protocol. The first sending module is used to send a link establishment request to the management process module based on the preset communication protocol, so that the management process module establishes a link connection with the internal communication module according to the link establishment request and the preset communication protocol, and sends a link establishment confirmation message to the internal communication module based on the preset communication protocol. The second sending module is used to respond to the link establishment confirmation message returned by the management process module, and send point table information to the management process module based on the preset communication protocol, so that the management process module performs feeder automation function testing on the distribution network based on the master station simulation model and the point table information, obtains test results, and sends the test results to the internal communication module based on the preset communication protocol.

Based on the preset communication protocol, the management process module sends a link establishment request to the management process module, enabling the management process module to establish a link connection with the internal communication module according to the link establishment request and the preset communication protocol. The management process module then sends a link establishment confirmation message to the internal communication module based on the preset communication protocol. In response to the link establishment confirmation message returned by the management process module, the management process module sends point table information to the management process module based on the preset communication protocol. This enables the management process module to perform feeder automation function testing on the distribution network based on the master station simulation model and the point table information, obtain test results, and send the test results back to the internal communication module based on the preset communication protocol. The point table information is obtained from the reports of the interval devices connected to the internal communication module. The management process module also receives the test results returned by the management process module. This achieves feeder automation function testing on the distribution network based on the master station simulation model in the management process module. When the structure of the distribution network changes, there is no need to upgrade and maintain the distribution master station, reducing the cost of feeder automation function testing on the distribution network.

[0031] Distribution networks directly serve users and permeate all aspects of social production and daily life. The quality and reliability of power supply from distribution networks are directly related to the power quality for users. Distribution automation is based on the primary network structure and equipment of distribution networks, comprehensively utilizes computer, information, and communication technologies, and integrates information with relevant application systems to achieve the detection, control, and rapid fault isolation of distribution networks, thereby improving power supply reliability, power quality, and enhancing the efficiency and effectiveness of power grid operation.

[0032] Feeder automation (FA) is one of the important functions of distribution network automation systems. It uses automated devices or systems to monitor the operation of distribution lines in real time, detect line faults in a timely manner, locate and isolate faulty areas, and restore power supply to non-faulty areas.

[0033] Currently, feeder automation function testing of the distribution network is mainly conducted using the distribution master station. Because the structure of the distribution network frequently changes, upgrades and maintenance of the distribution master station are often required to enable feeder automation testing. However, the complex structure of the distribution master station makes upgrades and maintenance costly, resulting in high costs for feeder automation function testing of the distribution network.

[0034] To address the aforementioned issues, the feeder automation function testing method, testing apparatus, equipment, and storage medium provided in this application acquire the preset communication protocol of the distribution master station, configure the preset communication protocol for the internal communication module, configure the management process module with the preset communication protocol, and send a link establishment request to the management process module based on the preset communication protocol. This allows the management process module to establish a link connection with the internal communication module based on the preset communication protocol, and send a link establishment confirmation message to the internal communication module based on the preset communication protocol. In response to the link establishment confirmation message returned by the management process module, the connection is established based on the preset communication protocol. The protocol sends point table information to the management process module, enabling the management process module to perform feeder automation function tests on the distribution network based on the master station simulation model and the point table information. The module obtains the test results and sends them to the internal communication module based on the preset communication protocol. The point table information is obtained from the reports of the interval devices connected to the internal communication module. The module also receives the test results returned by the management process module. This enables feeder automation function tests on the distribution network based on the master station simulation model in the management process module. When the structure of the distribution network changes, there is no need to upgrade and maintain the distribution master station, thus reducing the cost of feeder automation function tests on the distribution network.

[0035] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0036] Please see Figure 1 This illustration shows an application scenario diagram of a power distribution network provided in the embodiments of this application. The power distribution network may include a power distribution terminal device 100, a power distribution master station 200, and a bay device 300. The power distribution terminal device 100 is communicatively connected to the power distribution master station 200 and the bay device 300, and interacts with the power distribution master station 200 and the bay device 300 for data exchange.

[0037] The power distribution terminal equipment 100 may include a management process module 101 and an internal communication module 102. The management process module 101 may be connected to the internal communication module 102. The internal communication module 102 may be communicatively connected to the power distribution master station 200 and the bay device 300, and may interact with the power distribution master station 200 and the bay device 300 for data exchange.

[0038] The distribution terminal equipment 100 can be any one of the following: a distribution terminal unit (DTU), a feeder terminal unit (FTU), or a distribution transformer supervisory terminal unit (TTU), etc., without any limitation here.

[0039] The distribution master station 200 can be the center of the distribution network. The distribution master station 200 is responsible for data aggregation, analysis and decision-making. The distribution master station 200 can be any of the following: master station server, communication interface equipment or human-computer interaction equipment, etc. There is no limitation here.

[0040] The isolation device 300 can be a device used for isolation and control of circuits in the power distribution network. For example, the isolation device 300 can be at least one of circuit breakers, disconnect switches or current transformers, etc., without limitation.

[0041] In some implementations, the management process module 101 may be configured with a master station simulation model corresponding to the distribution master station 200. The master station simulation model can be used to simulate the functions of the distribution master station 200. The distribution master station 200 may be configured with a preset communication protocol, and the management process module 101 may be configured with a preset communication protocol.

[0042] The preset communication protocol can be any of the following: IEC 60870-5-101 protocol, IEC 60870-5-104 protocol, DNP3 protocol, Cyclic Data Transmission (CDT) protocol, etc., without any limitation here.

[0043] Please see Figure 2 This document illustrates a flowchart of a feeder automation function testing method provided in one embodiment of this application. In a specific embodiment, the feeder automation function testing method can be applied to, for example... Figure 1 The internal communication module 102 of the distribution terminal equipment 100 in the distribution network shown will be used as an example below to explain... Figure 2 The process shown is described in detail. The feeder automation function test method may include the following steps 401 to 404.

[0044] Step 401: Obtain the preset communication protocol of the power distribution master station.

[0045] In this embodiment of the application, when a user needs to perform feeder automation function testing on the distribution network, a test command can be sent to the internal communication module. After receiving the test command, the internal communication module can obtain the preset communication protocol of the distribution master station and configure the preset communication protocol for the internal communication module according to the preset communication protocol.

[0046] In some implementations, when a user needs to perform feeder automation function tests on the distribution network, they can send a test command to the internal communication module. After receiving the test command, the internal communication module can send a retrieval command to the distribution master station. After receiving the retrieval command, the distribution master station sends a preset communication protocol to the internal communication module, and the internal communication module receives the preset communication protocol returned by the distribution master station.

[0047] In some implementations, when a user needs to test the feeder automation function of the distribution network, they can send a test command to the internal communication module. After receiving the test command, the internal communication module can generate a prompt message and receive the preset communication protocol of the distribution master station uploaded by the user according to the prompt message.

[0048] The prompt message can be used to prompt the user to upload the preset communication protocol of the power distribution master station to the internal communication module. The prompt message can be at least one of the following: sound prompt, text prompt, or light prompt, etc., without limitation.

[0049] Step 402: Send a link establishment request to the management process module based on the preset communication protocol.

[0050] In this embodiment, the internal communication module obtains the preset communication protocol of the power distribution master station. After configuring the preset communication protocol for the internal communication module, it can send a link establishment request to the management process module based on the preset communication protocol. After receiving the link establishment request, the management process module can establish a link connection with the internal communication module based on the preset communication protocol and send a link establishment confirmation message to the internal communication module based on the preset communication protocol. The internal communication module receives the link establishment confirmation message returned by the management process module.

[0051] The management process module can be configured with a preset communication protocol, and the link establishment confirmation message can be used to indicate that the management process module has established a communication link with the internal communication module.

[0052] As an example, a link establishment request can be a request message with the identifier 0xaa.

[0053] Step 403: In response to the link establishment confirmation message returned by the management process module, send point table information to the management process module based on the preset communication protocol.

[0054] In this embodiment, the internal communication module sends a link establishment request to the management process module based on a preset communication protocol. This allows the management process module to establish a link connection with the internal communication module based on the preset communication protocol and send a link establishment confirmation message to the internal communication module. In response to the link establishment confirmation message returned by the management process module, the management process module sends point table information to the management process module based on the preset communication protocol. Upon receiving the point table information, the management process module inputs the point table information into the master station simulation model. Upon receiving the point table information, the master station simulation model performs feeder automation function tests on the distribution network based on the point table information, obtains the test results, and sends the test results to the internal communication module based on the preset communication protocol. The internal communication module receives the test results returned by the management process module.

[0055] The management process module can be pre-configured with a master station simulation model corresponding to the power distribution master station, and the point table information can be reported based on the interval equipment connected to the internal communication module.

[0056] Test results may include a first test result indicating that the feeder automation function test of the distribution network is qualified, or a second test result indicating that the feeder automation function test of the distribution network is unqualified.

[0057] The point information can be any of the following: remote signaling point information or telemetry point information; no limitation is made here.

[0058] As an example, remote signaling point information can be reported using a message identified by ASDU 0x01, and remote signaling point information can be reported using a message identified by ASDU 0x0D.

[0059] In some implementations, the internal communication module sends a link establishment request to the management process module based on a preset communication protocol. The management process module then establishes a link connection with the internal communication module according to the link establishment request and sends a link establishment confirmation message to the internal communication module. In response to the link establishment confirmation message returned by the management process module, the management process module sends point table information to the management process module at preset time intervals according to the preset communication protocol. Upon receiving the point table information, the management process module can input the point table information into the master station simulation model. The master station simulation model, upon receiving the point table information, can perform feeder automation function tests on the distribution network based on the point table information, obtain the test results, and send the test results to the internal communication module according to the preset communication protocol. The internal communication module receives the test results returned by the management process module. Reporting point table information to the management process module at preset time intervals reduces the number of simulations required by the master station simulation model, which helps reduce system resource consumption.

[0060] The preset duration can be set by the user according to the needs of the feeder automation function test. For example, the preset duration can be 5 minutes, 8 minutes, 10 minutes, etc., and there is no limitation here.

[0061] In some implementations, the internal communication module sends a link establishment request to the management process module based on a preset communication protocol. This allows the management process module to establish a link connection with the internal communication module based on the preset communication protocol and send a link establishment confirmation message to the internal communication module. In response to the link establishment confirmation message returned by the management process module, the module can determine whether the point table information reported by the interval device has undergone a sudden change. If a sudden change is detected, the module can send the point table information to the management process module based on the preset communication protocol. Upon receiving the point table information, the management process module can input it into the master station simulation model. The master station simulation model, upon receiving the point table information, can perform feeder automation function tests on the distribution network based on the point table information, obtain test results, and send the test results to the internal communication module based on the preset communication protocol. The internal communication module receives the test results returned by the management process module. Reporting point table information to the management process module when a sudden change is received from the point table information uploaded by the interval device reduces the number of simulations required by the master station simulation model, thus reducing system resource consumption.

[0062] The internal communication module can calculate the information difference between the point table information reported by the interval device at any adjacent time, and determine whether the point table information reported by the interval device has changed abruptly based on the information difference.

[0063] When an information difference is greater than or equal to an information difference threshold, it is determined that a sudden change has occurred in the point table information reported by the interval device; when no information difference is greater than or equal to the information difference threshold, it is determined that no sudden change has occurred in the point table information reported by the interval device. Based on the information difference between point table information reported by the interval device at adjacent times, the accuracy of determining whether a sudden change has occurred in the point table information reported by the interval device is improved.

[0064] The information difference threshold can be used to characterize the maximum information difference between the point table information reported by the interval device without any sudden changes.

[0065] As one implementation method, the point table information can be remote signaling point table information. When the remote signaling point table information changes abruptly, remote signaling point table information identified as COS can be sent to the management process module.

[0066] In one implementation, the point table information can be telemetry point table information, which can be checked every second to determine whether a sudden change has occurred. When a sudden change is detected, the telemetry dead zone value of the telemetry point table information is sent to the management process module as telemetry point table information.

[0067] In some implementations, the internal communication module sends a link establishment request to the management process module based on a preset communication protocol. This allows the management process module to establish a link connection with the internal communication module based on the preset communication protocol and send a link establishment confirmation message. In response to the confirmation message returned by the management process module, the module can determine whether the point table information reported by the interval device has undergone a sudden change. If no change is found, the module can send the point table information to the management process module at preset time intervals based on the preset communication protocol. Upon receiving the point table information, the management process module can input it into the master station simulation model. The master station simulation model, upon receiving the point table information, can perform feeder automation function tests on the distribution network based on the information, obtain test results, and send these results to the internal communication module based on the preset communication protocol. The internal communication module receives the test results returned by the management process module. Reporting point table information to the management process module at preset time intervals when a sudden change is received from the interval device reduces the number of simulations required by the master station simulation model, further reducing system resource consumption.

[0068] Step 404: Receive the test results returned by the management process module.

[0069] In this embodiment, the internal communication module responds to the link establishment confirmation message returned by the management process module and sends point table information to the management process module based on a preset communication protocol. This enables the management process module to perform feeder automation function testing on the distribution network based on the master station simulation model and the point table information, obtain test results, and send the test results back to the internal communication module based on the preset communication protocol. After that, the module can receive the test results returned by the management process module. This realizes the feeder automation function testing of the distribution network based on the master station simulation model in the management process module. When the structure of the distribution network changes, there is no need to upgrade and maintain the distribution master station, which reduces the cost of performing feeder automation function testing on the distribution network.

[0070] The solution provided in this application obtains the preset communication protocol of the distribution master station, configures the preset communication protocol for the internal communication module, and configures the management process module with the preset communication protocol. Based on the preset communication protocol, the management process module sends a link establishment request to the management process module, enabling the management process module to establish a link connection with the internal communication module according to the link establishment request and the preset communication protocol. The management process module then sends a link establishment confirmation message to the internal communication module based on the preset communication protocol. In response to the link establishment confirmation message returned by the management process module, the management process module sends point table information to the management process module based on the preset communication protocol. This enables the management process module to perform feeder automation function testing on the distribution network based on the master station simulation model and the point table information, obtain test results, and send the test results back to the internal communication module based on the preset communication protocol. The point table information is obtained from the reports of the interval devices connected to the internal communication module. The management process module also receives the test results returned by the management process module. This achieves feeder automation function testing on the distribution network based on the master station simulation model in the management process module. When the structure of the distribution network changes, there is no need to upgrade and maintain the distribution master station, reducing the cost of feeder automation function testing on the distribution network.

[0071] Please see Figure 3 This illustrates a flowchart of a feeder automation function testing method provided in another embodiment of this application. In a specific embodiment, the feeder automation function testing method can be applied to, for example... Figure 1 The internal communication module 102 of the distribution terminal equipment 100 in the distribution network shown will be used as an example below to explain... Figure 3 The process shown is described in detail. The feeder automation function test method may include the following steps 501 to 507.

[0072] Step 501: Obtain the preset communication protocol of the power distribution master station.

[0073] Step 502: Send a link establishment request to the management process module based on the preset communication protocol.

[0074] Step 503: In response to the link establishment confirmation message returned by the management process module, send point table information to the management process module based on the preset communication protocol.

[0075] Step 504: Receive the test results returned by the management process module.

[0076] In this embodiment, steps 501, 502, 503, and 504 can be found in the corresponding steps of the aforementioned embodiments, and will not be repeated here.

[0077] Step 505: In response to receiving the remote control command sent by the management process module, generate a remote control execution message.

[0078] In this embodiment, after receiving the test results returned by the management process module, the internal communication module can generate a remote control execution message in response to receiving the remote control command sent by the management process module.

[0079] Among them, the remote control command can be generated when the management process module passes the feeder automation function test of the distribution network, and the remote control execution message can be used to instruct the bay equipment to perform the corresponding remote control operation.

[0080] Remote control operation can include any one of the following: switch opening and closing operation, transformer control operation, protection and security device control operation, capacitor and reactor switching operation, etc., without limitation here.

[0081] In some implementations, after receiving the test results returned by the management process module, the internal communication module can, in response to receiving the remote control command sent by the management process module, determine whether the interval device has the conditions to perform remote control operations. If the conditions for remote control operations are determined to be met, a remote control execution message is generated. Generating the remote control execution message when the conditions for remote control operations are determined to be met avoids sending a remote control execution message to the interval device when the conditions for remote control operations are not met, which could lead to forced execution of remote control operations, potentially damaging the interval device and increasing security risks.

[0082] The internal communication module can generate remote control preset messages and send them to the interval device. After receiving the remote control preset messages, the interval device checks whether it has the conditions to perform remote control operations based on the remote control preset messages, obtains the verification result, and sends the verification result to the internal communication module. After receiving the verification result, the internal communication module can determine whether the interval device has the conditions to perform remote control operations based on the verification result.

[0083] The remote control preset message can be used to verify whether the interval device has the conditions to perform remote control operation. The verification result can include a first verification result indicating that the interval device has the conditions to perform remote control operation, or a second verification result indicating that the interval device does not have the conditions to perform remote control operation.

[0084] When the internal communication module receives the first verification result, it determines that the interval device meets the conditions for performing remote control operation; when the internal communication module does not receive the first verification result or the second verification result, or receives the second verification result, it determines that the interval device does not meet the conditions for performing remote control operation. Judging whether the interval device meets the conditions for remote control operation based on the remote control preset message improves the accuracy of judging the remote control operation conditions of the interval device.

[0085] Step 506: Send a remote control execution message to the interval device.

[0086] In this embodiment, after receiving the remote control command sent by the management process module, the internal communication module generates a remote control execution message and sends the remote control execution message to the interval device. After receiving the remote control execution message, the interval device can perform the corresponding remote control operation and send an execution failure reply information to the internal communication module if the execution of the remote control operation fails. The internal communication module receives the execution failure reply information returned by the interval device.

[0087] Among them, the execution failure response information can be used to indicate that the interval device failed to perform remote control operation.

[0088] Step 507: In response to the received execution failure reply information, generate the corresponding execution failure record.

[0089] In this embodiment, the internal communication module sends a remote control execution message to the interval device, so that the interval device can perform the corresponding remote control operation according to the remote control execution message. If the execution of the remote control operation fails, the interval device sends an execution failure reply message to the internal communication module. In response to the received execution failure reply message, the module can generate an execution failure record containing the execution failure reply message. This allows users to trace the feeder automation function test process of the distribution network based on the execution failure record, which is beneficial to improving the user experience during the feeder automation function test of the distribution network.

[0090] In some implementations, after receiving the test results returned by the management process module, the internal communication module can respond to the remote control command sent by the management process module, determine whether the interval device has the conditions to perform remote control operation, and when it is determined that the interval device does not have the conditions to perform remote control operation, it can generate a corresponding preset failure record so that the user can trace the feeder automation function test process of the distribution network according to the preset failure record, which is conducive to improving the user experience during the feeder automation function test of the distribution network.

[0091] The solution provided in this embodiment acquires the preset communication protocol of the distribution master station, sends a link establishment request to the management process module based on the preset communication protocol, and responds to the link establishment confirmation message returned by the management process module. It then sends point table information to the management process module based on the preset communication protocol, receives the test results returned by the management process module, generates a remote control execution message in response to the received remote control command from the management process module, and sends the remote control execution message to the interval equipment. In response to the received execution failure reply information, it generates a corresponding execution failure record. This enables feeder automation function testing of the distribution network based on the master station simulation model in the management process module. When the structure of the distribution network changes, there is no need to upgrade or maintain the distribution master station, reducing the cost of testing the feeder automation function of the distribution network.

[0092] Furthermore, in response to the received execution failure reply information, an execution failure record containing the execution failure reply information is generated so that users can trace the feeder automation function testing process of the distribution network based on the execution failure record, which helps to improve the user experience during the feeder automation function testing process of the distribution network.

[0093] Please see Figure 4 This illustrates a feeder automation function testing apparatus 600 provided in one embodiment of this application. The feeder automation function testing apparatus 600 can be applied to applications such as... Figure 1 The internal communication module 102 of the distribution terminal equipment 100 in the distribution network shown will be used as an example below to explain... Figure 4 The feeder automation function test device 600 shown will be described in detail. The feeder automation function test device 600 may include an acquisition module 601, a first transmission module 602, a second transmission module 603, and a receiving module 604.

The management process module can be configured with the preset communication protocol. The first sending module 602 can be used to send a link establishment request to the management process module based on the preset communication protocol, so that the management process module can establish a link connection with the internal communication module based on the preset communication protocol according to the link establishment request, and send a link establishment confirmation message to the internal communication module based on the preset communication protocol. The second sending module 603 can be used to respond to the link establishment confirmation message returned by the management process module and send point table information to the management process module based on the preset communication protocol, so that the management process module can perform feeder automation function tests on the distribution network based on the master station simulation model and point table information, obtain test results, and send the test results to the internal communication module based on the preset communication protocol. The point table information can be obtained based on the reporting of the bay equipment connected to the internal communication module. The receiving module 604 can be used to receive the test results returned by the management process module.

[0095] In some embodiments, the feeder automation function test apparatus 600 may further include a first determining module.

[0096] The first determining module can be used to determine whether the point table information reported by the interval device has changed abruptly before the second sending module 603 sends the point table information to the management process module based on the preset communication protocol.

[0100] The acquisition subunit can be used to acquire the information difference between the point table information reported by the interval device at any adjacent time; the first determination subunit can be used to determine that the point table information reported by the interval device has undergone a sudden change when there is an information difference greater than or equal to the information difference threshold; the second determination subunit can be used to determine that the point table information reported by the interval device has not undergone a sudden change when there is no information difference greater than or equal to the information difference threshold.

[0101] In some implementations, the second transmitting module 603 may further include a second transmitting unit.

[0102] The second sending unit can be used to send point table information to the management process module according to a preset time interval based on a preset communication protocol when the point table information reported by the determined interval device does not change.

[0103] In some implementations, the feeder automation function testing device 600 may further include a first generation module, a third transmission module, and a second generation module.

[0104] The first generation module can be used to generate a remote control execution message in response to receiving a remote control command sent by the management process module. The remote control command can be generated when the management process module passes the feeder automation function test of the distribution network. The third sending module can be used to send the remote control execution message to the bay device so that the bay device can perform the corresponding remote control operation according to the remote control execution message, and send an execution failure reply information to the internal communication module when the execution of the remote control operation fails. The second generation module can be used to generate a corresponding execution failure record in response to the received execution failure reply information.

[0105] In some implementations, the feeder automation function test apparatus 600 may also include a second determination module.

[0106] The second determining module can be used to determine whether the interval device has the conditions to perform remote control operation before the first generating module generates the remote control execution message.

[0107] In some implementations, the first generation module may include a first generation unit.

[0108] The first generation unit can be used to generate a remote control execution message when it is determined that the interval device has the conditions to perform remote control operation.

[0109] In some implementations, the second determining module may include a second generating unit, a third sending unit, a first determining unit, and a second determining unit.

[0110] The second generation unit can be used to generate a remote control preset message, which can be used to verify whether the interval device has the conditions to perform remote control operation; the third sending unit can be used to send the remote control preset message to the interval device, so that the interval device can verify whether it has the conditions to perform remote control operation according to the remote control preset message, and send the verification result to the internal communication module. The verification result can include a first verification result indicating that the interval device has the conditions to perform remote control operation, or a second verification result indicating that the interval device does not have the conditions to perform remote control operation; the first determining unit can be used to determine that the interval device has the conditions to perform remote control operation when the first verification result is received; the second determining unit can be used to determine that the interval device does not have the conditions to perform remote control operation when the first verification result and the second verification result are not received, or when the second verification result is received.

[0111] The solution provided in this embodiment obtains the preset communication protocol of the distribution master station, configures the preset communication protocol for the internal communication module, configures the management process module with the preset communication protocol, and sends a link establishment request to the management process module based on the preset communication protocol. The management process module then establishes a link connection with the internal communication module based on the preset communication protocol according to the link establishment request, and sends a link establishment confirmation message to the internal communication module based on the preset communication protocol. In response to the link establishment confirmation message returned by the management process module, the management process module sends point table information to the management process module based on the preset communication protocol. This allows the management process module to perform feeder automation function testing on the distribution network based on the master station simulation model and the point table information, obtain test results, and send the test results back to the internal communication module based on the preset communication protocol. The point table information is obtained from reports by the interval devices connected to the internal communication module. The management process module also receives the test results returned by the management process module. This achieves feeder automation function testing of the distribution network based on the master station simulation model in the management process module. When the structure of the distribution network changes, there is no need to upgrade or maintain the distribution master station, reducing the cost of feeder automation function testing of the distribution network.
