Abstract
Description
Technical Field
[0001] This invention belongs to the field of power distribution automation technology, and in particular relates to a complete function adaptive debugging system and method for all types of power distribution automation equipment. Background Technology
[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.
[0003] Power grid companies install a large number of new distribution automation systems, such as DTUs and FTUs, every year. However, the configuration and quality of these systems vary significantly across different units. Some equipment is even connected to the grid without proper commissioning, leading to frequent issues such as equipment not supporting remote parameter modifications, false alarms, and malfunctions. This severely hinders the practical application of distribution automation and fails to effectively improve the network's fault tolerance capabilities. The problems of slow commissioning speed, high manpower requirements, and low accuracy of traditional terminals are particularly prominent today, with the large-scale and widespread deployment of such equipment.
[0004] The existing automated commissioning adopts a method of command by the master station commissioning personnel and operation by the field commissioning personnel. The two parties complete information exchange by telephone. For example, the master station commissioning personnel inform the field commissioning personnel by telephone that the commissioning task of project X will be carried out next. Then, the field commissioning personnel perform the corresponding operation on the distribution automation terminal. The distribution automation terminal feeds back the commissioning results to the master station commissioning personnel. The master station commissioning personnel inform the field commissioning personnel by telephone whether the commissioning was successful or failed, and then proceed to the commissioning of the next project.
[0005] Therefore, the existing automated debugging process has at least the following technical problems:
[0006] (1) The commissioning of a single device takes a long time;
[0007] (2) Telephone communication is inconvenient for on-site commissioning personnel;
[0008] (3) At least two people, namely the main station debugging personnel and the on-site debugging personnel, are required to complete a debugging project;
[0009] (4) When there are a large number of terminals to be debugged, the main station may be undercapacity, the correctness and integrity of the joint commissioning work may not be guaranteed, and the joint commissioning task may be frequently delayed, which may affect the acceptance and commissioning of the power distribution terminal. Summary of the Invention
[0010] To overcome the shortcomings of the prior art, this invention provides a complete adaptive debugging system and method for all types of power distribution automation equipment, which effectively improves the efficiency of point-to-point debugging of power distribution terminals, realizes the early detection and rapid elimination of power distribution network faults, greatly improves the efficiency of on-site operation and maintenance, and ensures the safe and reliable operation of the power distribution network.

[0022] The industrial control computer is used to receive voltage, current and switching signals sent by the mobile terminal, send the voltage and current signals to the AC source, and send the switching signals to the switching action simulation mechanism.

[0024] The switch action simulation mechanism is used to receive switch signals sent by the industrial control computer and output corresponding switch signals to the power distribution automation terminal to complete the closed-loop point-to-point joint debugging test of the power distribution automation terminal.
[0025] Preferably, the AC source includes a three-phase independent current source and a four-phase independent voltage source. The outputs of the three-phase independent current source are connected in parallel to multiple sets of current output terminal groups. Each current output terminal group is provided with four current output terminals. The four current output terminals of each group are respectively connected to the three-phase current and the common point of the three-phase current of the three-phase independent current source through lines. A switch is provided on the connection line between the four current output terminals of each group and the three-phase independent current source. The switch action simulation mechanism is equipped with two input plug-ins and four output plug-ins. Each plug-in contains eight switching quantities, which can simulate eight switches at the same time. Each switch contains two inputs and four outputs.
[0026] Preferably, the joint debugging device further includes a high-current electromagnetic field simulation frame, which is connected to an AC source and used to amplify the current output by the three-phase independent current source.
[0027] Preferably, the distribution automation terminal communicates with the distribution automation master station via the power private network 101 or 104 protocol, and the distribution automation master station communicates with the joint commissioning device via wired or wireless network.
[0028] Preferably, when the power distribution automation master station and the joint commissioning device communicate via a wireless network, the joint commissioning device first communicates with a mobile terminal via the wireless network. The mobile terminal is authenticated by a unified permission system and accesses the external information network through an external network security interaction platform.

[0036] The above one or more technical solutions have the following beneficial effects:
[0037] This invention enables automatic point-to-point testing between distribution automation terminals and distribution automation master stations.

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0065] Overall Invention Concept:
[0066] This invention achieves authentication and interaction of debugging information between internal and external networks by constructing an enterprise information platform debugging channel; it assumes the dual functions of power distribution master station and joint commissioning master station through the DMS system functional module, adaptively expands joint commissioning projects, and realizes full-function debugging; and it builds a joint commissioning device to simulate the actual equipment working conditions on site, with mechanical actions accompanying the opening and closing of switches.
[0067] Example 1
[0068] This embodiment discloses a fully functional adaptive debugging system for all types of power distribution automation equipment.
[0069] like Figure 1 As shown, the complete adaptive commissioning system for all types of power distribution automation equipment includes a power distribution automation master station, power distribution automation terminals, and joint commissioning devices, among which:
[0070] The commissioning device is used to send commissioning requests to the distribution automation master station, receive commissioning instructions sent by the distribution automation master station, send corresponding voltage, current and switching signals to the distribution automation terminal based on the commissioning instructions, and receive commissioning success or failure information sent by the distribution automation master station to complete the closed-loop point-to-point commissioning test of the distribution automation terminal.
[0071] The distribution automation master station is used to receive commissioning requests sent by the joint commissioning device, send commissioning instructions to the joint commissioning device, and receive commissioning result information sent by the distribution automation terminal. Based on the commissioning result information, it determines whether the commissioning is successful or unsuccessful, and sends the commissioning success or failure information to the joint commissioning device.
[0072] The distribution automation terminal is used to receive voltage, current and switching signals sent by the commissioning device, perform commissioning, obtain commissioning result information based on the voltage, current and switching signals, and send the commissioning result information to the distribution automation master station.
[0073] Specifically:
[0074] (I) Enterprise Credit Platform Debugging Channel
[0075] The distribution automation terminal communicates with the distribution automation master station via the power dedicated network protocol 101 or 104. The distribution automation master station communicates with the joint commissioning device via wired or wireless network. When the distribution automation master station and the joint commissioning device communicate via wireless network, the joint commissioning device first communicates with the mobile terminal via the wireless network. The mobile terminal is authenticated by a unified access control system and accesses the external information network through an external network security interaction platform. The external information network interacts with the internal information network for specific data through isolation devices, and the internal information network achieves cross-regional information interaction through a cross-regional bus.
[0076] In this embodiment, the mobile terminal is a smartphone. The debugging device communicates with an external network APP via the Internet. The external network APP uses a personal smartphone as a carrier, and is authenticated by a unified permission system. It accesses the company's external information network through an external network security interaction platform, and performs specific data interaction with the internal information network through an isolation device. Cross-zone information interaction between zones I and III is achieved through a cross-zone bus. The debugging channel deployment architecture is as follows: Figure 2 As shown.
[0077] Based on the unified login authentication used by the external network APP, every debugging information exchange includes the logged-in user information. This enables one main station to debug with multiple terminal devices simultaneously, and multiple main stations to debug with multiple terminal devices simultaneously, without conflicting or lost debugging information. Specifically:
[0078] (1) The power distribution automation terminal and the mobile APP maintain a one-to-one relationship. A power distribution automation terminal can only be connected to one mobile APP for debugging at the same time.
[0079] (2) Mobile APP login adopts unified permission authentication. After each login, the login account information can be identified. This information will distinguish the city to which the account belongs. The channel is based on this information to distribute to different city GOMS systems.
[0080] (3) The interaction information between the mobile APP and the distribution network OMS system includes the APP login account information for each interaction. Based on this, the distribution network OMS system can know the APP login account for each interaction.
[0081] (4) The distribution network OMS system forwards the information of the mobile APP interaction to the DMS system. At the same time as each forwarding, the APP login account information is also forwarded to the DMS system, so that the DMS system can distinguish which account sent the message sent by the APP to the DMS system.
[0082] (5) After receiving the message, the DMS system processes the message and responds, and sends the response information to the distribution network OMS system. The response information still contains account information. Therefore, after receiving the message, the distribution network OMS system can know which mobile APP to forward it to based on the account information.
[0083] (II) Functional Modules of DMS Master Station System
[0084] The DMS system adds a dedicated terminal adaptive commissioning service on the master station side (simultaneously serving as both the distribution master station and the joint commissioning master station) to optimize and improve the terminal adaptive commissioning function with the joint commissioning equipment. Its main functions include the following modules:
[0085] (1) Data interaction architecture
[0086] To ensure the security of the commissioning process, the terminal adaptive commissioning service of the DMS master station system interacts with the field joint commissioning device through the State Grid Corporation's enterprise information platform. The front-end service of the DMS master station system collects data with the field commissioning terminal through the secure access zone, thus realizing secure communication between the master station system, the joint commissioning device and the commissioning terminal.
[0087] (2) Adaptive debugging editor
[0088] The adaptive debugging editor is mainly used for preparatory work before terminal integration testing. Its main functions include editing adaptive debugging terminal information, importing debugging terminal point tables, editing integration testing rule base, and managing the integration testing process.
[0089] (3) Monitoring of joint debugging links
[0090] The DMS master station system adds a communication link monitoring function with the joint debugging device to monitor the debugging link status in real time. If there is no data interaction within the rated time, the link status is detected to the joint debugging terminal via a heartbeat message; if a link interruption occurs or there is no data for a long time, a link abnormality alarm message is sent.
[0091] (4) Time synchronization function verification
[0092] After receiving a time synchronization debugging request from the joint debugging device, the DMS master station system sends a time synchronization message to the terminal under test and starts the debugging timer. If a time synchronization return message is received from the terminal under test within the set time, its correctness is verified. If a return message is received within the set time and the message verification is correct, the system sends a message to the joint debugging device indicating that the time synchronization function of the terminal has been successfully debugged; otherwise, it sends a message indicating that the debugging has failed.
[0093] (5) Telemetry function verification
[0094] After receiving the telemetry function debugging request from the joint debugging device, the DMS master station system starts the debugging timer function. It analyzes the telemetry data of the terminal collected by the front-end service and compares it with the required value of the measurement in the joint debugging plan. If the collected value of the measured point is within the allowable error within the set time, it sends a message to the joint debugging device that the debugging is successful; otherwise, it sends a message that the debugging has failed.
[0095] (6) Remote signaling function verification
[0096] Before initiating remote signaling commissioning, the commissioning device sets the remote signaling status of the field terminals to the initial commissioning state. After the commissioning device sends a remote signaling commissioning request, the DMS master station system checks whether the current remote signaling value matches the initial state. Remote signaling function commissioning begins once the remote signaling statuses of the DMS master station system and the field terminals are consistent. After the commissioning terminal sends the remote signaling point number to be commissioned, the DMS master station system starts the commissioning timer function and monitors remote signaling changes. If a correct remote signaling change is detected before the set time expires, a commissioning success message is sent to the commissioning device; otherwise, a commissioning failure message is sent.
[0097] (7) Remote control function verification
[0098] After receiving a remote control function debugging request from the joint debugging device for a certain switch, the DMS master station system performs remote control function debugging on that switch of the joint debugging terminal according to the process of "remote control verification - remote control return calibration - remote control execution - judgment of execution result". If all debugging steps are successful, a debugging success message is sent to the joint debugging device; otherwise, if an error occurs in any step, the remote control function debugging is considered to have failed, and a debugging failure message is sent.
[0099] (8) Verification of remote fixed value download and recall function
[0100] After receiving the remote setting download and recall request from the joint debugging device, the DMS master station system starts the debugging timing function, sends the debugging protection setting command to the terminal under test, and then sends the protection setting recall command to the terminal under test after the sending is successful. If the recall is successful and the recalled setting parameters are consistent with the sent debugging values, the system sends a message of debugging success to the joint debugging device; otherwise, it sends a message of debugging failure.
[0101] (9) Fault recording and recall function verification
[0102] After receiving a request for waveform recording files from the joint debugging device, the DMS master station system initiates the debugging timer function to request the fault waveform recording directory and files from the corresponding terminal under test. If the fault waveform recording file from the debugging terminal is received within the set time, a debugging success message is sent to the joint debugging device; otherwise, a debugging failure message is sent.
[0103] (10) Verification of other file transfer functions
[0104] Other file transfer functions mainly include the transfer and debugging of terminal historical logs, historical load data, etc., and the debugging process is consistent with that of waveform recording files. After receiving the corresponding file request from the joint debugging device, the DMS master station system starts the debugging timer function and calls the corresponding request command to request the file directory and files from the terminal under test. If the corresponding file is received from the debugging terminal within the set time, a debugging success message is sent to the joint debugging device; otherwise, a debugging failure message is sent.
[0105] (11) Parallel commissioning of multiple devices and terminals
[0106] To improve debugging efficiency, the DMS master station system has added support for parallel debugging of multiple integrated debugging devices and terminals. It identifies devices and terminals based on debugging parameters and realizes parallel debugging of multiple devices based on pre-collected data and integrated debugging interaction messages.
[0107] More specifically:
[0108] 1) Stop joint testing
[0109] like Figure 9 As shown, whenever the commissioning device sends a "manual stop" message (manual stop or emergency stop, etc.), the commissioning device immediately stops outputting voltage and current until it receives a "respond to manual stop" message. Upon receiving a "manual stop" message, the master station should stop the current commissioning process, clear the pending message buffer, and send the "respond to manual stop" message as the last message.
[0110] The joint debugging device sends a remote signal to point number 500 with a status bit of 1, indicating a stop command. Upon receiving this, the master station sends a remote control response to point number 500, also with a status bit of 1, indicating that the master station has received and responded. (The same applies if the master station initiates a stop.)
[0111] 2) Joint commissioning of voltage, current, active power, and reactive power telemetry
[0112] like Figure 10As shown, the joint debugging device sends a remote signal to point X with a status bit of 1, informing the master station to start the joint debugging test. After a 2-second delay (the delay is achieved by adding an initial status bit via Tengrui PTP, and this is repeated for all subsequent delays), the joint debugging device begins to increase the load. After receiving the remote signal from point X, the master station begins to judge the 20% remote signal and remotely feeds back the test results using special point numbers 401 and 402. For point number 401, a status value of 1 indicates that the 20% test was successful, and for point number 402, a status value of 1 indicates that the 20% test failed. After receiving 401 or 402, the joint debugging device outputs the 100% rated value. At the same time, the master station begins to judge the 100% rated value. After receiving the telemetry of the rated value, the master station feeds back the 100% rated result by sending the remote control point X. Status 1 indicates success, and status 0 indicates failure. After receiving the remote control point X, the joint debugging device begins to perform other tests.
[0113] When the master station is judging the result, if it does not receive a value, it will delay for 60 seconds and judge it as a failure; if it receives a value, it will immediately judge it as a success or failure.
[0114] 3) Power factor telemetry and commissioning
[0115] like Figure 11 As shown, the joint debugging device sends a remote signal at point X with a status bit of 1, informing the master station to start the joint debugging test. After a 2-second delay, the joint debugging device starts increasing the power. After receiving the remote signal at point X, the master station begins to judge the power factor of 1 and remotely feeds back the test results using special point numbers 401 and 402. For point number 401, a status value of 1 indicates that the power factor of 1 test was successful, and for point number 402, a status value of 1 indicates that the power factor of 1 test failed. After receiving 401 or 402, the joint debugging device proceeds to the next power factor output test. At the same time, the master station begins to judge and performs tests for power factors of 0.71 and 0 in sequence. When the master station receives the rated value telemetry for the last power factor of 0, it sends a remote signal at point X to feed back the test result of 1. Status 1 indicates success, and status 0 indicates failure. After receiving the remote signal at point X, the joint debugging device begins to perform other tests.
[0116] 4) Frequency telemetry and commissioning
[0117] like Figure 12As shown, the joint debugging device sends a remote signal at point X with a status bit of 1, informing the master station to start the joint debugging test. After a 2-second delay, the joint debugging device starts increasing the input. After receiving the remote signal at point X, the master station starts to judge the remote signal at frequency 45 and remotely feeds back the test results using special point numbers 401 and 402. For point number 401, a status value of 1 indicates that the power factor test is successful, while for point number 402, a status value of 1 indicates that the frequency test at 45 has failed. After receiving 401 or 402, the joint debugging device proceeds to the next frequency output test. At the same time, the master station starts to judge and performs tests at frequencies 50 and 55 in sequence. When the master station receives the rated value telemetry for the last frequency 55, it sends back the test result by sending remote point number X. A status bit of 1 indicates success, and a status bit of 0 indicates failure. After receiving remote point number X, the joint debugging device starts to perform other tests.
[0118] 5) Self-assess telemetry and debugging (battery voltage, signal strength, etc.)
[0119] like Figure 13 As shown, the joint debugging device sends a remote signal for point number X with a status bit of 1, informing the master station to start the joint debugging test. After receiving the remote signal for point number X, the master station actively queries the amplitude of the corresponding item and makes its own judgment. At the same time, it sends the remote control point number X to provide feedback on the test result. Status 1 represents success and status 0 represents failure. After receiving the remote control point X, the joint debugging device starts testing other items.
[0120] 6) Remote signaling and joint commissioning
[0121] like Figure 14 As shown, if the main station of the joint commissioning station reports that it cannot be executed, the joint commissioning device will stop and the process will end.
[0122] If the main station of the joint commissioning system reports that the operation can be executed, then the position can be manually changed or the automatic position can be simulated by switching the mechanism, and the process can continue.
[0123] The joint debugging device sends a remote signal for point X with a status bit of 1, informing the master station to begin the joint debugging test. After a 5-second delay, the joint debugging device or manual operation begins simulating switch position changes. Upon receiving the remote signal for point X, the master station actively queries the location of the corresponding item and autonomously determines its position. Simultaneously, it sends the remote control point X back to provide test results: status 1 indicates success, and status 0 indicates failure. After receiving the remote control point X, the joint debugging device begins testing other items. The remote signal test is divided into manual and automatic tests. Automatic tests output directly through the PTP template. Manual tests, i.e., manually operating the switch, involve first displaying a prompt box, then manually clicking to confirm, and finally manually operating the switch. The master station's judgment logic remains consistent.
[0124] 7) Remote control commissioning
[0125] like Figure 15As shown, remote control commissioning is mainly achieved through actual switching, with the master station determining success by issuing remote control commands and using corresponding remote signaling. The process is the same as the automatic telemetry determination.
[0126] 8) Time synchronization function joint debugging
[0127] like Figure 16 As shown, the joint debugging device sends a remote signal to point X with a status bit of 1, informing the master station to start the joint debugging test. After receiving the remote signal to point X, the master station actively queries the time synchronization of the corresponding item and makes its own judgment. At the same time, it sends the remote control point X to provide feedback on the test result. Status 1 represents success and status 0 represents failure. After receiving the remote control point X, the joint debugging device starts to perform tests on other items.
[0128] 9) File transfer integration testing
[0129] like Figure 17 As shown, the joint debugging device sends a remote signal for point number X with a status bit of 1, informing the master station to start the joint debugging test. After receiving the remote signal for point number X, the master station actively queries the corresponding project file and makes its own judgment. At the same time, it sends the remote control point number X to provide feedback on the test result. Status 1 represents success and status 0 represents failure. After receiving the remote control point X, the joint debugging device starts testing other projects.
[0130] 10) Remote setting download and recall testing integration
[0131] like Figure 18 As shown, the joint debugging device sends a remote signal to point X with a status bit of 1, informing the master station to start the joint debugging test. After receiving the remote signal to point X, the master station actively queries and modifies the settings of the corresponding item and makes its own judgment. At the same time, it sends the remote control point X to provide feedback on the test results. Status 1 represents success and status 0 represents failure. After receiving the remote control point X, the joint debugging device starts testing other items.
[0132] 11) Fault recording and recall testing integration
[0133] like Figure 19 As shown, the joint debugging device sends a remote signal for point number X with a status bit of 1, informing the master station to start the joint debugging test. After receiving the remote signal for point number X, the master station actively queries the amplitude of the corresponding item and makes its own judgment. At the same time, it sends the remote control point number X to provide feedback on the test result. Status 1 represents success and status 0 represents failure. After receiving the remote control point X, the joint debugging device starts testing other items.
[0134] 12) Overcurrent Stage I Protection Verification
[0135] Other protection logic verifications can be performed in the same manner.
[0136] like Figure 20As shown, if the main station of the joint commissioning station reports that the operation cannot be executed, the joint commissioning device will stop and the process will end; if the overcurrent stage I action test result is "failed", no preparations will be made before the no-action debugging, and a "failed" result will be sent. After receiving the result, the joint commissioning device will stop and the process will end; if the test result is "next step", the operation will continue. The protection test template is divided into reliable action and reliable non-action. First, a reliable action test is performed. The joint debugging device sends a remote signal to point X with a status bit of 1, informing the master station to begin the joint debugging test. After a 5-second delay, the joint debugging device begins to increase the output. Upon receiving the remote signal from point X, the master station begins to discriminate the remote signal at frequency 45 and remotely feeds back the test results using special points 401 and 402. For point 401, a status value of 1 indicates a successful protection function test; for point 402, a status value of 1 indicates a failed protection function test. After receiving 401 or 402, the joint debugging device proceeds to the next reliable non-action output test. Simultaneously, the master station begins its discrimination. If the master station does not receive the relevant protection remote signal within 20 seconds, the reliable non-action test is successful. The test result is fed back by sending remote signal point X, with a status of 1 indicating success and 0 indicating failure. After receiving remote signal point X, the joint debugging device begins other tests. The test template sending delay is implemented through the first status sequence, with a duration configurable to 5 seconds and an output value of 0, serving as the output status.
[0137] (III) Joint commissioning equipment
[0138] Adaptive debugging device such as Figure 3 As shown, a wireless network card with a USB interface is added to the industrial control computer, and the computer is connected to a mobile phone's Wi-Fi hotspot to connect to the enterprise communication platform. The industrial control computer is connected to an AC power source and a switch action simulation mechanism via the power supply port. The AC power source outputs AC voltage and current, and the switch action simulation mechanism inputs / outputs switching quantities. The AC current output by the AC power source is connected to a high-current electromagnetic field simulation frame via a cable, achieving an equivalent high-current electromagnetic field effect by outputting a smaller current.
[0139] (1) The AC source contains a three-phase independent current source and a four-phase independent voltage source. The three-phase independent current source can be output to one of the multiple sets of terminals through a switching switch. Its structural diagram is shown in the figure. Figure 4 As shown.
[0140] The three-phase independent current source contains eight sets of switching switches, each set with four switches. Only one set of switches is closed at a time, connecting the internal three-phase current source and its common point to its corresponding external terminal. The schematic diagram of the internal four-phase voltage source is shown below. Figure 5 As shown.
[0141] The connection method between the AC source and the terminal under test is as follows: Figure 6 As shown, the zero-sequence current is achieved by combining the three-phase currents; for the distribution terminals with connection voltages Uab and Ucb, Un is not required.
[0142] (2) The AC current source output current range is 0~6A. The output current is not directly connected to the secondary current circuit, but is connected to a multi-turn coil, and then the primary open-ended current transformer is clamped onto this coil. In this way, even if the tester only outputs a small current, it can achieve the effect of an equivalent large primary current through this multi-turn coil. Figure 7 For example, assuming the coil has 100 turns and a current of 6A is applied, this is equivalent to a primary current of 600A being applied to the current transformer. Depending on the test scale, multiple multi-turn coils connected in series can form a high-current electromagnetic field simulation frame.
[0143] (3) The switch action simulation mechanism adopts a 4U 19-inch standard chassis, which houses 2 input modules and 4 output modules. Each module contains 8 switch signals, such as... Figure 8 As shown. This method can simulate 8 switches simultaneously, each switch containing 2 inputs (open and closed) and 4 outputs (closed, open, switch not energized, and low pressure interlock).
[0144] The integrated testing device includes a power supply module, a CPU module, a current amplifier module, and a voltage amplifier module. The power supply module is connected to the CPU module, current amplifier module, and voltage amplifier module, respectively. The CPU module is connected to both the current amplifier module and the voltage amplifier module, respectively. Figure 10 As shown.
[0145] (iv) Joint commissioning process
[0146] Adaptive joint debugging closed-loop point implementation includes:
[0147] The distribution automation terminal and the distribution automation master station communicate via the dedicated power network protocol 101 or 104 in actual field operation. The distribution automation master station and the commissioning device communicate and exchange information via wired or 4G networks. The distribution automation master station and the commissioning device pre-construct a consistent commissioning task sheet, which includes test items and test plans. The distribution automation master station and the commissioning device transmit closed-loop commissioning commands through a question-and-answer interactive mode.
[0148] During point-to-point testing, the commissioning device actively sends a request command to the automation master station system. The distribution automation master station sends relevant test instructions to the commissioning device according to the commissioning task sheet. After receiving the instructions, the commissioning device outputs relevant voltage, current, and switching signals to the distribution automation terminal according to the commissioning task sheet. The distribution automation terminal converts the relevant signals into telemetry, telesignal, and other messages and sends them to the automation master station. The distribution automation master station performs intelligent judgment, thereby completing the closed-loop point-to-point commissioning test of the distribution automation terminal.
[0149] Example 2
[0150] This embodiment discloses a method for adaptive debugging of the complete functions of all types of power distribution automation equipment.
[0151] like Figure 2 As shown, the adaptive commissioning method for all types of power distribution automation equipment includes the following steps:
[0152] The commissioning unit sends a commissioning request to the distribution automation master station, and the distribution automation master station receives the commissioning request from the commissioning unit and sends commissioning instructions to the commissioning unit.
[0153] The commissioning unit receives commissioning instructions from the distribution automation master station and sends corresponding voltage, current and switching signals to the distribution automation terminal based on the commissioning instructions.
[0154] The distribution automation terminal receives voltage, current and switching signals sent by the joint commissioning device, performs commissioning, obtains commissioning result information based on the voltage, current and switching signals, and sends the commissioning result information to the distribution automation master station.
[0155] The distribution automation master station receives the debugging result information sent by the distribution automation terminal, determines whether the debugging is successful or unsuccessful based on the debugging result information, and sends the debugging success or failure information to the joint commissioning device.
[0156] The commissioning device receives commissioning success or failure information sent by the distribution automation master station and completes the closed-loop point-to-point commissioning test of the distribution automation terminal.
[0157] Those skilled in the art will understand that the modules or steps of the present invention described above can be implemented using general-purpose computer devices. Optionally, they can be implemented using computer-executable program code, thereby allowing them to be stored in a storage device for execution by a computer device, or they can be fabricated as separate integrated circuit modules, or multiple modules or steps can be fabricated as a single integrated circuit module. The present invention is not limited to any particular combination of hardware and software.
[0158] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
