Abstract
Description
Technical Field
[0001] This application relates to the field of intelligent joint debugging technology, specifically to an intelligent terminal joint debugging method for controlling a relay protection device to automatically increase its load using a handheld terminal. Background Technology
[0002] In distribution automation systems, before feeder terminal units and substation terminals are put into operation, their remote signaling, telemetry, remote control, and protection logic functions need to be verified through joint commissioning tests. During the joint commissioning tests, a significant portion of the test items require the use of a relay protection tester (relay protection instrument) to apply specific current or voltage to the distribution terminal to excite the distribution terminal to generate corresponding remote signaling changes or telemetry changes.
[0003] In existing technologies, the operation of relay protection devices (SPDs) mainly relies on manual methods. Commissioning personnel manually operate the buttons or knobs on the SPD panel according to the commissioning task sheet, setting parameters such as the amplitude, frequency, and duration of the output voltage or current, and then starting the output. After completing each test item, the commissioning personnel need to reset the SPD parameters before proceeding to the next test.
[0004] This manual operation method has the following problems: manual parameter setting is prone to errors due to misoperation, resulting in inaccurate test conclusions; debugging personnel need to be familiar with the operation interface of different models of relay protection instruments, resulting in high training costs; after the relay protection instrument is upgraded, the conclusion judgment still requires manual observation and recording; for sequence transmission tasks that require multi-step timing output, manual step-by-step operation of the relay protection instrument is extremely cumbersome and it is difficult to guarantee timing accuracy.
[0005] Therefore, there is an urgent need for a joint commissioning method that can automatically control the increase of relay protection device, freeing commissioning personnel from tedious manual operations. Summary of the Invention
[0006] To address the aforementioned problems, this invention provides a smart terminal co-firing method for controlling a relay protection device to automatically increase its load using a handheld terminal.
[0007] This invention provides a smart terminal commissioning method for automatically increasing the quantity of a relay protection device using a handheld terminal. The method is applied to a system including a commissioning platform, a handheld terminal, a relay protection tester, and a power distribution terminal. The method includes the following steps: The commissioning platform generates a commissioning task order based on the remote control templates associated with the power distribution terminal; The handheld terminal loads the joint debugging task list from the joint debugging platform and receives the user's selection operation for the joint debugging items that require additional incentives; The handheld terminal sends a transmission start request to the joint debugging platform. In response to the request, the joint debugging platform generates a status sequence file corresponding to the joint debugging item and returns it to the handheld terminal. The handheld terminal transmits the status sequence file to the relay protection tester via wireless communication. The relay protection tester parses the state sequence file and automatically outputs current and / or voltage to the distribution terminal according to the increment parameters defined therein; The power distribution terminal responds to the current and / or voltage quantities, generates a remote signaling change control signal and a telemetry value change, sends the remote signaling change control signal to the actuator, receives the execution result returned by the actuator, and uploads the remote signaling change control signal, the telemetry value change and the execution result to the joint commissioning platform; The joint debugging platform compares the received data with the preset expected values in the state sequence file, generates a transmission conclusion, and pushes it to the handheld terminal for display.
[0008] The commissioning platform automatically generates task orders based on templates. Handheld terminals act as command relays and human-machine interaction hubs, driving the relay protection devices to automatically increase their loads. The commissioning platform then compares the actual transmitted data with the expected values to generate conclusions. This solution changes the inefficient traditional method of manually operating relay protection devices item by item and manually verifying messages, improving the automation level and operational efficiency of distribution terminal commissioning, and reducing the risk of human error.
[0009] As a preferred embodiment of the technical solution of the present invention, the joint debugging platform automatically determines the output parameters of the state sequence file according to the type of the joint debugging item, including: When the joint commissioning item is a remote signaling joint commissioning item, the state sequence file defines an electrical quantity sequence used to generate a step change in order to trigger the remote signaling change of the distribution terminal; When the joint commissioning item is a telemetry joint commissioning item, the state sequence file defines an electrical quantity sequence with smooth amplitude changes to trigger changes in the telemetry values of the distribution terminal. When the joint debugging item is a sequence drive task, the status sequence file defines multiple sets of electrical quantity output sequences arranged in time sequence, and the output timing of each set of sequences matches the preset expected action timing in the sequence drive task.
[0010] For remote signaling integration projects, the system generates a sequence of electrical quantities with step changes, which can quickly trigger remote signaling changes in distribution terminals. For telemetry integration projects, it generates a sequence of electrical quantities with smooth amplitude changes, which can accurately test the linear response characteristics of telemetry values. For sequence transmission tasks, it generates multiple sets of time-ordered output sequences, which can simulate complex fault timing scenarios. The integration platform automatically matches the corresponding output parameter generation strategy according to the type of integration project, eliminating the need for manual settings by the user and reducing operational complexity.
[0011] As a preferred embodiment of the technical solution of the present invention, when the handheld terminal sends a status sequence file to the relay protection tester via wireless communication, a packet transmission and acknowledgment retransmission mechanism is adopted, specifically including: The handheld terminal splits the status sequence file into multiple data packets, each containing a sequence number, total number of packets, checksum, and valid data payload. After receiving each data packet, the relay protection tester returns a reception confirmation message to the handheld terminal. The confirmation message contains the sequence number of the received packet. If the handheld terminal does not receive an acknowledgment message for a data packet within a preset timeout period, the data packet will be automatically retransmitted. After all data packets have been transmitted, the handheld terminal sends a transmission completion command to the relay protection tester. The relay protection tester performs integrity verification on all received data packets. If the verification passes, it returns a success response to the handheld terminal; otherwise, it requests the retransmission of missing or incorrect data packets.
[0012] By splitting the file into multiple data packets and confirming receipt of each packet, coupled with a timeout retransmission mechanism, the potential packet loss issue during Bluetooth transmission is effectively resolved, ensuring that the status sequence file arrives at the relay protection device intact and error-free. After transmission, a data packet integrity check is performed. If the check fails, a retransmission of missing or incorrect data packets is requested, further guaranteeing the accuracy of the transmitted data and preventing errors or test failures due to file corruption.
[0013] As a preferred embodiment of the technical solution of the present invention, the joint debugging platform generates a state sequence file corresponding to the joint debugging item, specifically including: The joint debugging platform parses the operation category, point number, and terminal identifier from the transmission start request; Based on the terminal identifier and the current task order number, query the corresponding joint debugging task order from the database, locate the target joint debugging item in the joint debugging task order according to the point number, and read the preset expected value information in the joint debugging item. Invoke the corresponding state sequence generation algorithm based on the operation category: If the operation category is remote signaling joint debugging item, a state sequence containing three output segments is generated. The first segment is the initial hold output, the second segment is the step jump output, and the third segment is the recovery output. The point number of the remote signaling point is marked in the sequence file as the expected trigger object. If the operation category is telemetry integration, a state sequence containing multiple levels of linear amplitude changes is generated, starting from the initial value and gradually increasing to the target value with a fixed step size. Each amplitude plateau is maintained for a preset duration, and the amplitude and its allowable error range are filled in the expected telemetry value field corresponding to each amplitude plateau. If the operation category is a sequence drive task, the preset expected action timing table is read from the task sheet, a multi-step output sequence is generated, each step outputs a specific combination of electrical quantities, and the corresponding remote signaling point identifier and expected displacement direction are filled in the expected trigger field of that step. The generated output parameters are encapsulated into a state sequence file according to a predefined data structure, and after adding a timestamp and a checksum, they are returned to the handheld terminal.
[0014] As a preferred embodiment of the technical solution of the present invention, the method further includes: During the automatic increment process, the relay protection tester monitors its own output status in real time and transmits the execution status back to the handheld terminal; the execution status includes the current step number, the executed time, the remaining time, and the actual output amplitude; If the relay protection tester detects an output abnormality, it immediately stops outputting and sends a fault alarm message. The fault alarm message includes a fault type code and the output step number at the time of the fault. After receiving a fault alarm message, the handheld terminal displays the alarm information on the user interface and provides operation options such as stopping the current task, retrying the current step, and skipping the current step to continue execution.
[0015] Commissioning personnel can use a handheld terminal to view the current step number, elapsed execution time, remaining time, and actual output amplitude in real time, intuitively understanding the progress of the increase and improving the controllability of on-site commissioning. When the relay protection instrument detects an output abnormality, it immediately stops the output and sends a fault alarm message. The handheld terminal displays the alarm information and provides operation options such as stop, retry, and skip, facilitating timely response by commissioning personnel to abnormalities and avoiding damage to the equipment under test or causing safety hazards.
[0016] As a preferred embodiment of the technical solution of the present invention, it further includes: When the joint debugging item in the joint debugging task sheet is a sequential transmission task containing multiple sub-tasks, after all the sub-tasks of the sequential transmission task are executed, the overall transmission conclusion of the sequential transmission task and the individual transmission conclusion of each sub-task are generated. If the overall transmission result is a failure, the joint debugging platform identifies the failed subtask in the user interface of the handheld terminal and provides an independent retransmission operation entry for each failed subtask. In response to the user's click to retransmit a failed subtask, the joint debugging platform only regenerates the state sequence file of the increment logic corresponding to the failed subtask, and re-executes the increment and conclusion judgment of the subtask through the handheld terminal and the relay protection tester. After re-execution, the joint debugging platform updates the individual transmission conclusion of the subtask and recalculates the overall transmission conclusion of the sequence transmission task.
[0017] When the entire sequence transmission task fails, only the failed subtasks need to be retransmitted; the entire sequence task does not need to be re-executed. For complex sequences containing multiple subtasks, incremental retesting can reduce the retesting time from the total execution time to the execution time of a single failed subtask. After re-execution, the system automatically updates the individual transmission conclusion of the subtask and recalculates the overall transmission conclusion of the sequence, ensuring that the conclusion status of all joint debugging items in the task list remains synchronized and accurate.
[0018] As a preferred embodiment of the technical solution of the present invention, the handheld terminal supports a batch debugging mode, specifically including: After the user selects multiple integration items and sets the execution order in the integration task list, the handheld terminal sends a batch transmission start request to the integration platform. The joint debugging platform executes the following automated process for each joint debugging item in the order described above: Generate the state sequence file corresponding to the joint debugging item and return it to the handheld terminal; Receive remote signaling / telemetry data and execution results sent by the power distribution terminal after the relay protection tester increases the quantity; Draw and store the transmission conclusions for this joint debugging item.
[0019] Users can select multiple integration items at once and set the execution order. The system will automatically execute them in sequence, eliminating the need for users to click to start each item individually, thus reducing manual waiting and operation time.
[0020] As a preferred embodiment of the technical solution of the present invention, the joint debugging platform configures differentiated time windows for different types of joint debugging items, specifically including: For the remote signaling joint debugging item, configure the first preset time window, with the expected value being the change in remote signaling status; For telemetry integration, a second preset time window is configured, with the expected value being that the telemetry value enters the allowable error range. For sequential transmission tasks, a third preset time window is configured, with the expected value being that the sequential actions are completed in time sequence; The joint debugging platform monitors data within the corresponding time window. If a match is found, the system is considered successful; if no match is found within the time limit, the system is considered unsuccessful.
[0021] The remote signaling change response is fast, the telemetry value changes require sampling and filtering, and the sequence transmission task involves multiple timing steps. Differentiated configuration makes the judgment logic more consistent with actual working conditions. Once the expected value is matched within the time window, the timing ends early and the judgment is successful, without waiting for the full window to end. This can significantly shorten the time of a single commissioning when the equipment response is fast.
[0022] As a preferred embodiment of the technical solution of the present invention, it further includes: Before performing the joint commissioning item that requires additional relay protection tester, the handheld terminal sends a terminal status query request to the joint commissioning platform. The query request includes the nameplate ID of the power distribution terminal to be commissioned. In response to the query request, the joint commissioning platform obtains the current remote signaling status and telemetry values of the power distribution terminal from the real-time control area master station and returns them to the handheld terminal as the initial state reference before the increase. The handheld terminal displays the received current remote signaling status and telemetry values in the user interface; After the relay protection tester completes the adjustment and the joint debugging platform obtains the transmission conclusion, the handheld terminal automatically records the initial state, expected value, actual value, conclusion and completion timestamp of the joint debugging item, and uploads the above records to the joint debugging platform to generate a joint debugging report.
[0023] Before implementing additional parameters, the current remote signaling status and telemetry values of the power distribution terminal are acquired and displayed to facilitate commissioning personnel in confirming that the terminal is in the expected initial state and avoid misjudgments due to incorrect initial states. The initial state, expected value, actual value, conclusion, and timestamp of each joint commissioning item are automatically recorded to form traceable joint commissioning historical data for subsequent generation of joint commissioning reports and quality analysis.
[0024] As a preferred embodiment of the technical solution of the present invention, the relay protection tester has multiple independent output channels, including at least three voltage output channels and three current output channels; The state sequence file defines output parameters for each output channel, including: channel identifier, output type, output waveform type, output amplitude, output frequency, output phase, and output duration. After parsing the state sequence file, the relay protection tester outputs the data in parallel according to the independent parameters of each channel to simulate various fault conditions of a three-phase circuit, including three-phase short circuit, two-phase short circuit, single-phase ground fault and overcurrent fault. The power distribution terminal responds to the composite electrical quantities generated by the parallel output of multiple channels, generates corresponding protection action signals as remote signaling change control signals and sends them to the actuator, and uploads the protection action signals to the joint commissioning platform; The commissioning platform compares the received protection action signals with the preset expected protection action timing in the status sequence file to verify the correctness of the protection logic of the power distribution terminal.
[0025] As a preferred embodiment of the technical solution of the present invention, the handheld terminal also provides a manual editing function for the status sequence file, specifically including: After selecting a debugging item on the handheld terminal, the user can choose between two modes: automatic sequence generation or custom sequence. In automatic sequence generation mode, the commissioning platform automatically generates a status sequence file based on the type of commissioning item and the template parameters of the power distribution terminal and returns it to the handheld terminal. In custom sequence mode, the handheld terminal displays a sequence editing interface, where users can manually set the following parameters: number of output steps, output channel for each step, current / voltage amplitude for each step, duration of each step, interval between each step, and the telemetry or telecontrol point to be triggered for each step. After the user completes the custom sequence editing, the handheld terminal uploads the custom sequence parameters to the joint debugging platform. The joint debugging platform generates a status sequence file based on the custom sequence parameters and returns it to the handheld terminal, which then sends it to the relay protection tester for execution via wireless communication.
[0026] As can be seen from the above technical solution, this application has the following advantages: The handheld terminal receives the user's selection of commissioning items; the commissioning platform automatically generates a status sequence file and returns it to the handheld terminal; the handheld terminal then sends the file to the relay protection device via Bluetooth; the relay protection device automatically parses and outputs current / voltage values. The entire process requires no manual operation of the relay protection device panel, freeing commissioning personnel from tedious manual parameter settings. From task order loading, status sequence file generation, Bluetooth transmission, automatic quantity increase, power distribution terminal response, execution result upload to conclusion judgment and push, the entire process is automated, requiring no manual intervention or recording, thus improving commissioning efficiency.
[0027] The power distribution terminal sends remote signaling change control signals to the actuator and receives the execution results returned by the actuator, which are then uploaded to the joint commissioning platform. This ensures that the joint commissioning conclusions are based not only on the signals generated by the power distribution terminal itself, but also on the actual action feedback from the actuator, thereby improving the accuracy and reliability of the joint commissioning results.
[0028] Commissioning personnel only need to select the commissioning item on the handheld terminal and click start, without needing to master the operation methods of different models of relay protection devices, which reduces personnel training costs and on-site operation difficulty.

[0032] To make the purpose, features, and advantages of this application more apparent and understandable, specific embodiments and accompanying drawings will be used to clearly and completely describe the technical solution protected by this application. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments.

[0033] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this application and in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0034] like Figure 1 As shown, this embodiment of the invention provides a smart terminal joint commissioning method for automatically increasing the quantity of a relay protection device controlled by a handheld terminal. This method is applied to a system including a joint commissioning platform, a handheld terminal, a relay protection tester, and a distribution terminal. The joint commissioning platform is deployed in the management information area of the power monitoring system and is responsible for generating task orders, generating status sequence files, and determining conclusions. The handheld terminal can be a mobile phone or tablet computer with a dedicated application installed, serving as the operating interface for on-site commissioning personnel. The relay protection tester is a smart relay protection device with wireless communication capabilities (Bluetooth communication is used in this embodiment) used to receive instructions from the handheld terminal and automatically output electrical quantities. The handheld terminal establishes a communication connection with the joint commissioning platform via a 4G, 5G, or Wi-Fi network, and the handheld terminal establishes a point-to-point wireless communication connection with the relay protection tester via Bluetooth. The method includes the following steps: S1. The commissioning platform generates a commissioning task order based on the remote control template associated with the power distribution terminal. Specifically, the commissioning platform pre-synchronizes all the three-remote template data from the distribution automation master station system. Each three-remote template contains the remote signaling point table, remote measurement point table, and remote control point table corresponding to a specific type of distribution terminal. On-site commissioning personnel initiate a commissioning request through a handheld terminal, or the administrator creates a commissioning request on the commissioning platform. After receiving the commissioning request, the commissioning platform extracts the equipment model or three-remote template identifier of the distribution terminal from the request information. Based on the equipment model or template identifier, it performs a matching query in the local template cache. The local template cache pre-stores all the three-remote template data synchronized from the distribution automation master station system. Each template data includes the template name, template version number, and the corresponding remote signaling point table (including the point number, name, and default status of each remote signaling point), remote measurement point table (including the point number, name, range, and unit of each remote measurement point), and remote control point table (including the point number, name, and connection / disconnection identifier of each remote control point).
[0035] After successful matching, the commissioning platform extracts the complete three-remote point table corresponding to the template. According to the preset task order generation rules, each remote signaling point in the three-remote point table is split into two commissioning items: closing and opening. Each remote control point is split into two commissioning items: closing and opening. Each telemetry point is marked as a commissioning item that needs additional testing. System-level test items such as parameter setting reading and waveform file retrieval are added as additional commissioning items. The commissioning platform automatically fills in the preset expected value for each commissioning item, generates a globally unique task item identifier, and aggregates all commissioning items into a structured commissioning task order data set. This task order also contains metadata information such as task order number, associated terminal nameplate ID, task order validity period, and generation timestamp.
[0036] S2. The handheld terminal loads the joint debugging task list from the joint debugging platform and receives the user's selection operation for the joint debugging items that require additional incentives. On-site debugging personnel open the application on their handheld terminal, log in to the joint debugging system, and can see a list of joint debugging tasks assigned to them. After clicking on a task, the handheld terminal retrieves the complete data of that task from the joint debugging platform and displays all joint debugging items in a list format on the user interface. Debugging personnel can select the joint debugging item to be executed from the task list as needed.
[0037] S3. The handheld terminal sends a transmission start request to the joint debugging platform. In response to the request, the joint debugging platform generates a status sequence file corresponding to the joint debugging item and returns it to the handheld terminal. After the user selects the debugging option, the handheld terminal immediately sends a transmission start request to the debugging platform. This request includes at least the terminal identifier, operation category, point number, and debugging value. Figure 2As shown, the joint debugging platform parses the operation category, point number, and terminal identifier from the transmission start request sent by the handheld terminal; based on the terminal identifier and task order number, it queries the database for the joint debugging task order data set corresponding to the terminal, locates the target joint debugging item in the task order according to the point number, and reads the preset expected value information in the joint debugging item. Among them, for remote signaling joint debugging items, the expected value is the target displacement state of the remote signaling point, i.e., merging or separating; for telemetry joint debugging items, the expected value is the target range of telemetry values; for sequential transmission tasks, the expected value is the time sequence of actions of multiple remote signaling points.
[0038] The joint debugging platform calls the corresponding state sequence generation algorithm based on the operation category: If the operation category is a remote signaling joint debugging item, the platform generates a state sequence containing three output segments: the first segment is the initial hold output, the second segment is the step transition output, and the third segment is the recovery output. The platform also marks the point number of the remote signaling point in the sequence file as the expected trigger object. If the operation category is a telemetry joint debugging item, the platform generates a state sequence containing multi-level linear amplitude changes. Starting from the initial value, the amplitude increases step-by-step to the target value with a fixed step size. Each amplitude platform is held for 2 seconds, and the expected telemetry value field corresponding to each amplitude platform is filled with the amplitude and its allowable value. Error range; If the operation category is a sequence transmission task, the platform reads the preset expected action timing table of the sequence task from the task list. The timing table records the remote signaling point number, action sequence number, and expected action time interval corresponding to each step. Based on this, the platform generates a multi-step output sequence. Each step outputs a specific combination of electrical quantities, and fills in the corresponding remote signaling point identifier and expected displacement direction in the expected trigger field of that step. The joint debugging platform encapsulates all generated output parameters into a JSON or XML format status sequence file according to a predefined data structure, adds a timestamp and check code, and returns it to the handheld terminal.
[0039] The data structure includes fields such as file header identifier, task ID, terminal ID, operation category, total number of steps, output channel identifier for each step, output type, output amplitude, output frequency, duration, expected trigger point number, and expected value.
[0040] S4. The handheld terminal sends the status sequence file to the relay protection tester via wireless communication connection; Specifically, the handheld terminal first establishes a Bluetooth connection with the relay protection tester, and then sends the status sequence file to the relay protection tester via the Bluetooth transmission protocol. To ensure the reliability of Bluetooth transmission, this embodiment adopts a packet-based transmission and acknowledgment retransmission mechanism, as detailed below.
[0041] The handheld terminal splits the status sequence file into multiple data packets, each packet's size adapted to the Bluetooth Maximum Transmission Unit (MTBU). Each data packet's header contains a sequence number, total number of packets, a checksum, and a valid data payload. Upon receiving each data packet, the relay protection tester immediately sends a reception confirmation message to the handheld terminal, containing the sequence number of the received packet. The handheld terminal starts a timeout timer when sending each data packet; if no confirmation message is received within the preset timeout period, the packet is automatically retransmitted. After all data packets have been transmitted, the handheld terminal sends a transmission completion command to the relay protection tester. The relay protection tester performs integrity checks on all received data packets, including checking for consecutive sequence numbers, correct total number of packets, and a valid checksum for each packet. If the checksum passes, the relay protection tester returns a success response to the handheld terminal; if the checksum fails, the relay protection tester sends a list of missing or erroneous data packet sequence numbers to the handheld terminal, which then retransmits the corresponding data packets.
[0042] S5. The relay protection tester parses the state sequence file and automatically outputs current and / or voltage to the power distribution terminal according to the increment parameters defined therein; After successfully receiving the complete state sequence file, the relay protection tester begins parsing it. Based on the input parameters defined in the state sequence file, the relay protection tester automatically outputs the corresponding current and / or voltage to the distribution terminal. In this embodiment, the commissioning platform can automatically determine the output parameters of the state sequence file according to the type of commissioning item. Specifically, when the commissioning item is a remote signaling commissioning item, the state sequence file defines a sequence of electrical quantities used to generate a step change. For example, for a remote signaling point to be tested, the state sequence file first defines an initial output, then defines a step transition, and finally restores the initial output. This step-change electrical quantity can quickly trigger the remote signaling change of the distribution terminal. When the commissioning item is a telemetry commissioning item, the state sequence file defines a sequence of electrical quantities with smoothly changing amplitude. When the commissioning item is a sequence drive task, the state sequence file defines multiple sets of time-arranged electrical quantity output sequences. Each set of output sequences corresponds to triggering a remote signaling point action, and the output timing of each set of sequences matches the preset expected action timing in the sequence drive task.
[0043] S6. The power distribution terminal responds to the current and / or voltage, generates a remote signaling change control signal and a telemetry value change, sends the remote signaling change control signal to the actuator, receives the execution result returned by the actuator, and uploads the remote signaling change control signal, the telemetry value change and the execution result of the actuator to the joint commissioning platform. Specifically, when the input electrical quantity meets the preset threshold conditions, the power distribution terminal will generate remote signaling change control signals, such as switch closed or open signals, as well as changes in telemetry values, such as changes in current or voltage sampling values.
[0044] The actuator can be a circuit breaker, load switch, recloser, or sectionalizing device. Upon receiving a control signal, the actuator performs the corresponding switching action, such as closing or opening, and returns the execution result to the distribution terminal. The execution result typically includes the actual closed state of the switch, the actual open state of the switch, the action completion timestamp, and an action exception code. After receiving the execution result returned by the actuator, the distribution terminal uploads the execution result, along with the remote signaling change control signal and telemetry value changes, to the joint commissioning platform through the distribution automation master station system.
[0045] S7. The joint debugging platform compares the received data with the preset expected values in the state sequence file, generates a transmission conclusion, and pushes it to the handheld terminal for display.
[0046] In this embodiment, the commissioning platform configures differentiated time windows for different types of commissioning items. Specifically, for remote signaling commissioning items, the first preset time window is configured as 30 seconds, with the expected value being the change of the remote signaling state from the initial state to the target state. Within this 30-second time window, the commissioning platform continuously monitors the remote signaling data from the distribution terminal. Once a remote signaling change signal matching the expected value is received, the timing is immediately terminated early, and the commissioning item is deemed successful. For telemetry commissioning items, the second preset time window is configured as 50 seconds, with the expected value being the telemetry value entering a preset allowable error range. The commissioning platform monitors the telemetry values within 50 seconds, and when the telemetry values stabilize within the allowable error range, success is determined. For sequence transmission tasks, the third preset time window is configured as 120 seconds, with the expected value being all remote signaling points in the sequence acting sequentially according to a preset timing sequence. Within this 120-second time window, the commissioning platform monitors the remote signaling change sequence, and when the received change timing sequence perfectly matches the preset timing sequence, success is determined. If no data matching the expected value is received within the corresponding time window, the joint debugging item is deemed to have failed, and the reason for failure is recorded as "waiting timeout - no expected value received".
[0047] After the joint debugging platform generates the transmission conclusion, it pushes the conclusion to the handheld terminal for display in real time. Debugging personnel can see the conclusion of the current joint debugging item, as well as actual values, time consumption, and other information on the handheld terminal.
[0048] In some embodiments, when the integration task item in the integration task list is a sequential transmission task containing multiple subtasks, an incremental retesting mechanism is provided. The specific steps are as follows.
[0049] The relay protection tester sequentially executes the output sequence of multiple electrical quantities defined in the state sequence file. After outputting each set of electrical quantities, it waits for the distribution terminal to generate the corresponding remote signaling change. After all subtasks are completed, the commissioning platform generates the overall transmission conclusion of the sequence transmission task and the individual transmission conclusion of each subtask. If the overall transmission conclusion is successful, the sequence task ends; if the overall transmission conclusion is unsuccessful, the commissioning platform marks the failed subtask with a set color in the user interface of the handheld terminal and provides an independent "re-transmission" operation entry for each failed subtask.
[0050] The debugging personnel trigger the re-transmission button next to a failed subtask. In response, the commissioning platform only regenerates the state sequence file for the increment logic corresponding to the failed subtask, rather than regenerating the state sequence file for the entire sequence of tasks. This state sequence file is sent to the relay protection tester via a handheld terminal, and the relay protection tester only executes the increment output corresponding to that subtask. After re-execution, the commissioning platform updates the individual transmission conclusion of that subtask based on the newly received data and recalculates the overall transmission conclusion of the sequence of transmission tasks. If all failed subtasks succeed after retesting, the overall transmission conclusion is updated to success.
[0051] To further improve debugging efficiency, some embodiments of the handheld terminal support batch debugging mode. Debuggers select multiple debugging items in the integration task list, triggering batch debugging. The handheld terminal then displays a settings interface, allowing the user to set the execution order of the debugging items. After user confirmation, the handheld terminal sends a batch execution start request to the integration platform. This request includes a list of selected debugging item identifiers and their preset execution order.
[0052] The commissioning platform, following this execution sequence, performs the following automated process for each commissioning item: generating a status sequence file corresponding to the commissioning item and returning it to the handheld terminal; instructing the handheld terminal to send the status sequence file to the relay protection tester via Bluetooth; receiving the remote signaling / telemetry data and execution results sent by the distribution terminal after the relay protection tester has increased its load; and deriving and storing the transmission conclusion for the commissioning item. After the transmission conclusion for the current commissioning item is obtained, the commissioning platform automatically begins processing the next commissioning item in the execution sequence until all selected commissioning items have been processed. Throughout the entire batch commissioning process, the handheld terminal displays in real time the name of the currently executing commissioning item, the time elapsed for the current item, the conclusion for the current item, and the percentage of completed commissioning items compared to the total number.
[0053] During the automatic current / voltage increment process of the relay protection tester, some embodiments also provide real-time monitoring and anomaly handling mechanisms. While outputting current / voltage, the relay protection tester monitors its own output status in real time, including the currently executing step number, the elapsed execution time of the current step, the remaining time of the current step, and the actual output current / voltage amplitude. This execution status information is transmitted back to the handheld terminal in real time via Bluetooth and displayed on the handheld terminal's user interface, allowing commissioning personnel to understand the increment progress in real time.
[0054] If the relay protection tester detects an output abnormality, such as output overload, output voltage / current exceeding tolerance, or internal temperature exceeding a safety threshold, it immediately stops output and generates a fault alarm message. This alarm message includes a fault type code (e.g., 01 for overload, 02 for exceeding tolerance, and 03 for exceeding temperature limits) and the output step number at which the fault occurred. Upon receiving the alarm message, the handheld terminal outputs an alarm dialog box displaying the fault type and location, and provides three operation options: stop the current task, retry the current step, and skip the current step to continue execution. The debugging personnel select the appropriate operation option based on the actual situation, and the system continues execution according to the user's instructions.
[0055] Before performing any commissioning tests requiring additional relay protection testers, some embodiments also provide an initial state query function. After the commissioning personnel trigger the start button for a commissioning test, the handheld terminal first sends a terminal status query request to the commissioning platform. This request includes the nameplate ID of the distribution terminal to be commissioned. In response to this query request, the commissioning platform obtains the current telemetry status and telemetry values of the distribution terminal from the real-time control area master station via the cross-regional synchronization channel and returns this data to the handheld terminal. The handheld terminal uses this data as the initial state reference before additional testing and displays it on the user interface. The commissioning personnel can then confirm that the distribution terminal is in the expected initial state, ensuring that the starting conditions for the test are correct.
[0056] After the relay protection tester completes the adjustment and the joint debugging platform obtains the transmission conclusion, the handheld terminal automatically records the complete joint debugging record for this item, including: initial state, expected value, actual value, transmission conclusion, and completion timestamp. The handheld terminal uploads this record to the joint debugging platform, which stores all joint debugging records in its database for subsequent generation of joint debugging reports and quality analysis.
[0057] In this embodiment, the relay protection tester has multiple independent output channels, including three voltage output channels Ua, Ub, and Uc, and three current output channels Ia, Ib, and Ic. The status sequence file defines output parameters for each output channel, including: channel identifier, output type, output waveform type, output amplitude, output frequency, output phase, and output duration.
[0058] After parsing the state sequence file, the relay protection tester outputs the data in parallel according to the independent parameters of each channel. This multi-channel independent parallel output capability enables the relay protection tester to realistically simulate various fault conditions of a three-phase circuit, including three-phase short circuit (Ua, Ub, and Uc simultaneously drop to 0V, while Ia, Ib, and Ic simultaneously rise to the short-circuit current), two-phase short circuit (e.g., Ub and Uc short circuit), single-phase ground fault (e.g., Ua grounded, Ia rises to the fault current), and overcurrent fault (the current in one phase exceeds the rated value by several times).
[0059] The distribution terminal responds to the composite electrical quantities generated by the parallel output of multiple channels and generates corresponding protection action signals according to its internally configured protection logic. For example, when the A-phase current is detected to exceed the overcurrent protection setting, the distribution terminal generates an overcurrent protection action signal. This signal is sent to the actuator as a remote signaling change control signal and simultaneously uploaded to the commissioning platform. The commissioning platform compares the received protection action signal with the preset expected protection action timing in the status sequence file. For example, if the expected protection action signal is received within 40 milliseconds after the fault current is applied, and the actual received time is 42 milliseconds, which is within the allowable error range, the protection logic is determined to be correct. In this way, this embodiment can automatically verify the correctness of the distribution terminal's protection logic.
[0060] To meet the needs of special testing scenarios, the handheld terminal in this embodiment also provides a manual editing function for state sequence files. After selecting a debugging item on the handheld terminal, the user can choose between two modes: automatic sequence generation or custom sequence.
[0061] In automatic sequence generation mode, the commissioning platform automatically generates a status sequence file based on the type of commissioning item and the template parameters of the power distribution terminal, and returns it to the handheld terminal. The entire process requires no user intervention and is suitable for conventional testing scenarios.
[0062] In custom sequence mode, the handheld terminal displays a sequence editing interface where users can manually set the following parameters: number of output steps; output channels for each step; current / voltage amplitude for each step; duration of each step; interval between steps; and the expected remote signaling or telemetry point to be triggered for each step. After the user completes the custom sequence editing, the handheld terminal uploads the user-set custom sequence parameters to the commissioning platform. The commissioning platform generates a state sequence file that meets the required format based on these parameters and returns it to the handheld terminal. The handheld terminal then sends the state sequence file to the relay protection tester via Bluetooth for execution. This method allows advanced users to flexibly customize test sequences according to actual field conditions, meeting non-standard testing needs.
