Description

Technical Field

[0001] This invention belongs to the field of information management for relay protection devices, and specifically relates to a method and system for defining and managing relay protection terminals. Background Technology

[0002] To ensure the safe operation of the power grid, relay protection devices are widely used at all voltage levels in the power system. These devices are characterized by a wide variety of protection types, rapid updates, and long operating cycles. Furthermore, as the functional configuration of relay protection devices becomes increasingly flexible, with engineering-defined input and output information and editable protection logic, the actual terminal definitions of the protection devices often differ from standard manuals and drawings. Without effective management of this actual engineering information, the use and maintenance of the protection devices will be inconvenient. Therefore, easily obtaining a terminal definition diagram or display interface consistent with actual operation is of great significance for maintenance personnel in equipment maintenance and troubleshooting.

[0003] In existing technologies, the process for defining relay protection device terminals is typically as follows: The device is shipped with default terminal definitions, where the input and output terminal names are generic and consistent with the standard instruction manual; designers create design drawings based on the protection device terminal definitions, and the default generic terminal names are redefined as specific names according to engineering design needs, reflected in the drawings; during the on-site commissioning phase, commissioning is conducted based on the design drawings. If any terminal definitions are modified during this phase, feedback will be provided to the designers to revise the design drawings; as-built drawings are prepared based on the final design drawings after on-site commissioning; maintenance personnel use the as-built drawings as their work basis. If any terminal definitions are modified during the maintenance phase, the final maintenance drawings are generated by updating the maintenance drawings. The overall process is as follows: Figure 1 As shown; however, the terminal definition names in the instruction manuals and device menus of existing relay protection devices are all factory default generic names, which cannot actually reflect the specific definitions in engineering applications. Therefore, the device itself cannot provide a terminal definition diagram consistent with the actual terminal definitions in the engineering. Furthermore, the protection device usually displays the connected information through different function menus, without a comprehensive terminal definition diagram. Therefore, during the use and maintenance of the device, it is necessary to comprehensively query the required information through the use or maintenance drawings, device manuals, device menus, etc., which involves a lot of data. In particular, if the data is missing due to the long time or poor management, or if the drawings are not updated in time after the actual terminal definitions in the engineering are modified, complete terminal definition information cannot be obtained, which is not conducive to information query and maintenance. This leads to the problems of cumbersome operation and low maintenance efficiency in obtaining terminal definition information during the use and maintenance of the device. Summary of the Invention

[0004] The purpose of this invention is to provide a method and system for defining and managing relay protection terminals, which solves the problem that existing methods for defining relay protection device terminals are difficult to provide terminal definitions that are consistent with the actual terminal definitions in engineering, resulting in cumbersome information acquisition operations and low operation and maintenance efficiency.

[0005] To achieve the above objectives, the present invention provides a relay protection terminal definition management system, including a terminal definition management function enabling / disabling module, a terminal definition editing module, and a terminal definition management module;

[0006] The terminal definition management function enable / disable module is used to select whether to use the terminal definition editing module function. If the terminal definition editing module is not used, it will be in a closed state, and the factory default terminal definition will be used as the current relay protection terminal definition. If the terminal definition editing module is used, it will be in a closed state.

[0007] The terminal definition editing module is used to display the terminal number of the defined terminal that can be modified and provide an input interface for the name information of the terminal corresponding to the terminal number when the terminal definition management function is selected to use the terminal definition editing module function. The input terminal name information is used as the current relay protection terminal definition. It is also used to standardize the terminal definition modification rules.

[0008] The terminal definition management module is used to receive the current relay protection terminal definition input by the terminal definition editing module when the terminal definition management function is selected to use the terminal definition editing module function. It updates all menus in the relay protection device that contain relay protection terminal definitions according to the received current relay protection terminal definitions. It also generates a corresponding actual terminal definition file for the project according to the received current relay protection terminal definitions for storage.

[0009] The beneficial effects of the above technical solution are as follows: By selecting whether to use the terminal definition editing module through the terminal definition management function enable / disable module, the basic functions of relay protection terminal definition can be guaranteed to adapt to the working conditions where the factory default terminal definition is used and remains basically unchanged, as well as situations where no modification to the terminal definition is required; The terminal definition editing module provides an editing information input interface, and the terminal definition management module updates the modified terminal definition in the menu of the relay protection device involving the terminal definition, while generating and saving the modified terminal definition file that is consistent with the actual project, ensuring that the terminal definition in the relay protection device can be saved in a timely manner consistent with the actual terminal definition in the project.

[0010] Furthermore, the terminal definition management function enable / disable module is also used to pop up a terminal definition modification inquiry window in the terminal definition editing module or the set equipment debugging or commissioning terminal when the control terminal definition editing module is in the open state, so as to prompt the staff to modify the current relay protection terminal definition to the terminal definition consistent with the current engineering situation.

[0011] The beneficial effects of the above technical solution are: it can display that the current terminal definition is in an editable state, prompting relevant personnel to modify the relay protection terminal definition in a timely manner according to the current working conditions, and further ensuring that the terminal definition in the relay protection device can be saved in a timely manner consistent with the actual terminal definition in the project.

[0012] Furthermore, the terminal definition file includes terminal definition diagrams that can be viewed in the corresponding menu of the relay protection device, terminal definition diagrams that can be directly printed through the printing interface of the relay protection device, and terminal definition diagrams that can be remotely read through communication.

[0013] The beneficial effects of the above technical solution are: the terminal definition file can be obtained in multiple ways, thereby providing maintenance personnel with accurate, fast and comprehensive terminal definition diagrams, improving the efficiency of equipment maintenance and troubleshooting.

[0014] Furthermore, the terminal definition management module is also used to obtain the terminal definition file corresponding to the factory default terminal definition;

[0015] The terminal definition management module includes a menu browsing submodule, a printing submodule, and a remote reading submodule, which are respectively used to view the corresponding menu of the relay protection device for the terminal definition diagram corresponding to the factory default terminal definition, control the relay protection device to print the terminal definition diagram corresponding to the factory default terminal definition, and send the terminal definition diagram corresponding to the factory default terminal definition via communication when performing remote reading.

[0016] The beneficial effects of the above technical solution are as follows: the terminal definition management module provides the terminal definition file corresponding to the factory default terminal definition, and provides support for menu browsing, device printing and remote reading, without the need for additional reference materials, making it convenient for relevant personnel to view.

[0017] Furthermore, the method for modifying the standard terminal definition is as follows: when generating the current relay protection terminal definition, by default, the function characters corresponding to the relay protection device terminal hardware are appended after the input terminal name information, so that the generated current relay protection terminal definition is consistent with the relay protection device terminal hardware.

[0018] The beneficial effects of the above technical solution are: to avoid the problem that the terminal definition is inconsistent with the actual relay protection device terminal hardware due to modification errors when modifying the terminal definition, so that the generated current relay protection terminal definition cannot reflect the actual hardware terminal situation.

[0019] This invention also provides a relay protection terminal definition management method. The terminal definition management function enable / disable module selects whether to use the terminal definition editing module function. If the terminal definition editing module is not used, it is controlled to be in an open state, and the factory default terminal definition is used as the current relay protection terminal definition. If the terminal definition editing module is used, it is controlled to be in an open state.

[0020] When the terminal definition editing module function is selected, the terminal definition editing module displays the terminal number of the defined terminal that can be modified and provides an input interface for the name information of the terminal corresponding to the terminal number. The input terminal name information is used as the current relay protection terminal definition. When inputting the terminal name information, the terminal definition modification rules are also standardized.

[0021] When the terminal definition editing module function is selected, the terminal definition management module also receives the current relay protection terminal definition input from the terminal definition editing module, updates all menus in the relay protection device that contain relay protection terminal definitions according to the received current relay protection terminal definitions, and generates the corresponding actual terminal definition file for the project according to the received current relay protection terminal definitions for storage.

[0022] The beneficial effects of the above technical solution are as follows: By selecting whether to use the terminal definition editing module through the terminal definition management function enable / disable module, the basic functions of relay protection terminal definition can be guaranteed to adapt to the working conditions where the factory default terminal definition is used and remains basically unchanged, as well as situations where no modification to the terminal definition is required; The terminal definition editing module provides an editing information input interface, and the terminal definition management module updates the modified terminal definition in the menu of the relay protection device involving the terminal definition, while generating and saving the modified terminal definition file that is consistent with the actual project, ensuring that the terminal definition in the relay protection device can be saved in a timely manner consistent with the actual terminal definition in the project.

[0023] Furthermore, when the control terminal definition editing module is in an open state, the terminal definition management function enable / disable module will also pop up a terminal definition modification inquiry window in the terminal definition editing module or the set equipment debugging or commissioning terminal to prompt the staff to modify the current relay protection terminal definition to be consistent with the current engineering situation.

[0024] The beneficial effects of the above technical solution are: it can display that the current terminal definition is in an editable state, prompting relevant personnel to modify the relay protection terminal definition in a timely manner according to the current working conditions, and further ensuring that the terminal definition in the relay protection device can be saved in a timely manner consistent with the actual terminal definition in the project.

[0025] Furthermore, the terminal definition file includes terminal definition diagrams that can be viewed in the corresponding menu of the relay protection device, terminal definition diagrams that can be directly printed through the printing interface of the relay protection device, and terminal definition diagrams that can be remotely read through communication.

[0026] The beneficial effects of the above technical solution are: the terminal definition file can be obtained in multiple ways, thereby providing maintenance personnel with accurate, fast and comprehensive terminal definition diagrams, improving the efficiency of equipment maintenance and troubleshooting.

[0027] Furthermore, the corresponding menu of the relay protection device can be viewed through the menu browsing submodule of the terminal definition management module, which shows the terminal definition diagram corresponding to the factory default terminal definition. The printing submodule of the terminal definition management module controls the relay protection device to print the terminal definition diagram corresponding to the factory default terminal definition. When performing remote reading, the terminal definition diagram corresponding to the factory default terminal definition is sent via communication through the remote reading submodule of the terminal definition management module.

[0028] The beneficial effects of the above technical solution are as follows: the terminal definition management module provides the terminal definition file corresponding to the factory default terminal definition, and provides support for menu browsing, device printing and remote reading, without the need for additional reference materials, making it convenient for relevant personnel to view.

[0029] Furthermore, the method for modifying the standard terminal definition is as follows: when generating the current relay protection terminal definition, by default, the function characters corresponding to the relay protection device terminal hardware are appended after the input terminal name information, so that the generated current relay protection terminal definition is consistent with the relay protection device terminal hardware.

[0030] The beneficial effects of the above technical solution are: to avoid the problem that the terminal definition is inconsistent with the actual relay protection device terminal hardware due to modification errors when modifying the terminal definition, so that the generated current relay protection terminal definition cannot reflect the actual hardware terminal situation.

[0031] Figure 1 This is a flowchart illustrating the existing definition of terminals for relay protection devices in the background art of this invention;

[0032] Figure 2This is a flowchart illustrating the workflow of the relay protection terminal definition management system in an embodiment of the present invention. Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Relay Protection Terminal Definition Management System Implementation Example

[0035] This embodiment provides a technical solution for a relay protection terminal definition management system. The system includes a terminal definition management function enabling / disabling module, a terminal definition editing module, and a terminal definition management module. (Refer to...) Figure 2 The content within the dashed box in the figure; In this embodiment, the terminal definition management function enabling / disabling module, the terminal definition editing module, and the terminal definition management module are all located in the CPU of the respective relay protection device. In other embodiments, they can also be set separately outside the relay protection device and communicate with the relay protection device to transmit relevant data.

[0036] The terminal definition management function enable / disable module is used to select whether to use the terminal definition editing module. If the option is not selected, the terminal definition editing module is kept in an inactive state, and the factory default terminal definition is used as the current relay protection terminal definition. This ensures the basic functionality of the relay protection terminal definition and is suitable for situations where the factory default terminal definition is used and remains basically unchanged, or where no modification to the terminal definition is required. If the option is selected, the terminal definition editing module is kept active. The terminal definition management function enable / disable module also has a terminal definition modification prompt function. When the terminal definition editing module is active, it will pop up a terminal definition modification prompt window on itself or at the designated equipment commissioning or operation terminal to prompt the staff to modify the current relay protection terminal definition to be consistent with the current engineering situation.

[0037] The terminal definition editing module is used to display the terminal numbers of terminals that can be modified when the terminal definition management function is enabled or disabled, and to provide an input interface for the name information of the corresponding terminals for each terminal number. The input terminal name information is used as the current relay protection terminal definition. It is also used to standardize the terminal definition modification rules. In this embodiment, the terminal definition editing module can be implemented through a human-machine interface device, such as a display screen with input function or a monitor with a keyboard. According to the terminal numbers of terminals that can be modified, the relevant personnel select the terminal to be modified and edit according to the terminal numbers displayed by the human-machine interface device, and enter the name information input interface of the terminal through the human-machine interface device, enter the new name information of the terminal and save it. Then the terminal definition editing module will generate the current relay protection terminal definition according to the input terminal name information.

[0038] In this embodiment, the terminal definition modification rule requires that the terminal definition be consistent with the actual device terminal hardware; that is, the input terminal name must be defined as XXXX input, and the output terminal can only be defined as XXXX output. Therefore, the terminal definition editing module is also used to append the function characters corresponding to the relay protection device terminal hardware to the input terminal name information by default, so that the terminal definition is consistent with the relay protection device terminal hardware. The way to standardize the terminal definition modification rule is: when generating the current relay protection terminal definition, by default, append the function characters corresponding to the relay protection device terminal hardware to the input terminal name information, so that the generated current relay protection terminal definition is consistent with the relay protection device terminal hardware. This can avoid the problem that the terminal definition is inconsistent with the actual relay protection device terminal hardware due to modification errors, and the generated current relay protection terminal definition cannot reflect the actual hardware terminal situation.

[0039] In this embodiment, the terminal definition management module is used to implement two management functions when the terminal definition management function enable / disable module selects to use the terminal definition editing module function: management of the factory default terminal definition and management of the current relay protection terminal definition. The management of the factory default terminal definition includes: controlling the generation of a complete terminal definition file corresponding to the factory default terminal definition to be stored in the protection device memory, and providing menu viewing, printing, and remote reading functions for the terminal definition file corresponding to the factory default terminal definition. The terminal definition file includes a terminal definition diagram for viewing in the corresponding menu of the relay protection device, a terminal definition diagram for direct printing through the printing interface of the relay protection device, and a terminal definition diagram for remote reading via communication. Therefore, the terminal definition management module includes a menu browsing submodule, a printing submodule, and a remote reading submodule, which are respectively used to view the corresponding menu of the relay protection device for viewing the terminal definition diagram corresponding to the factory default terminal definition, control the relay protection device to print the terminal definition diagram corresponding to the factory default terminal definition, and send the terminal definition diagram corresponding to the factory default terminal definition via communication when performing remote reading.

[0040] The management of current relay protection terminal definitions includes: receiving the current relay protection terminal definitions generated by the terminal definition editing module; updating all menus in the relay protection device that contain relay protection terminal definitions according to the received current relay protection terminal definitions; and generating and storing the corresponding actual terminal definition file for the project according to the received current relay protection terminal definitions. Therefore, the terminal definition management module also provides menu viewing, printing, and remote reading functions for the generated actual terminal definition file for the project. Specifically, its menu browsing submodule, printing submodule, and remote reading submodule are also used to view the corresponding menus of the relay protection device for the actual terminal definition diagram of the project, control the relay protection device to print the actual terminal definition diagram of the project, and send the actual terminal definition diagram of the project via communication when performing remote reading.

[0041] In this embodiment, the actual engineering terminal definition file corresponding to the current relay protection terminal definition is stored in the memory of the relay protection device to which the terminal definition management module belongs. In other embodiments, it may also be stored in other locations. Therefore, as long as the terminal definition management function's terminal control and terminal definition editing module are in an open state, a terminal definition modification prompt window will pop up through the terminal definition editing module to provide editing information input interface. The terminal definition management module updates the modified terminal definitions in the menu of the relay protection device involving terminal definitions, and simultaneously generates and saves the modified terminal definition file consistent with the actual engineering situation. This ensures that the terminal definitions in the relay protection device are timely and consistent with the actual engineering terminal definitions. Furthermore, in this embodiment, the terminal definition file is directly stored in the relay protection device itself, avoiding data loss due to time constraints or poor management, and preventing inconvenience in operation and maintenance. It provides both the complete factory default terminal definition file and the real-time generated terminal definition file consistent with the actual engineering situation. Both types of terminal definition files are supported by menu browsing, device printing, and remote reading through the terminal definition management module. The terminal definition file can be viewed as a terminal definition diagram in the relay protection device menu, printed directly through the device printing interface, and remotely read via communication. This provides maintenance personnel with accurate, fast, and comprehensive terminal definition diagrams, improving the efficiency of equipment maintenance and troubleshooting.

[0042] Example of Relay Protection Terminal Definition Management Method

[0043] This embodiment provides a technical solution for a relay protection terminal definition management method. This method employs the relay protection terminal definition management system described in the above embodiment. The terminal definition management function enable / disables the use of the terminal definition editing module. If the module is disabled, it remains in an inaccessible state, using the factory default terminal definition as the current relay protection terminal definition. If the module is enabled, it remains in an open state. Furthermore, a terminal definition modification prompt window pops up in the terminal definition editing module or at the designated equipment debugging or commissioning terminal to prompt staff to modify the current relay protection terminal definition to match the actual engineering situation.

[0044] When the terminal definition editing module function is selected, the terminal definition editing module displays the terminal numbers that can be modified and provides an input interface for the name information of the corresponding terminal for each terminal number. The current relay protection terminal definition is generated based on the input terminal name information. The terminal definition modification rules are also standardized when the terminal name information is entered.

[0045] When the terminal definition editing module function is selected, the terminal definition management module also receives the current relay protection terminal definition generated by the terminal definition editing module. All menus in the relay protection device that contain relay protection terminal definitions are updated according to the received current relay protection terminal definitions. Furthermore, a terminal definition file corresponding to the actual project is generated and stored based on the received current relay protection terminal definitions. The terminal definition file includes terminal definition diagrams that can be viewed in the corresponding menu of the relay protection device, terminal definition diagrams that can be directly printed through the relay protection device's printing interface, and terminal definition diagrams that can be remotely read via communication. In this embodiment, the terminal definition files are mainly divided into two types: terminal definition files corresponding to the factory default terminal definitions and terminal definition files generated in real-time that are consistent with the actual project. Each type of terminal definition file includes corresponding terminal definition diagrams that can be viewed in the corresponding menu of the relay protection device, terminal definition diagrams that can be directly printed through the relay protection device's printing interface, and terminal definition diagrams that can be remotely read via communication.

[0046] Furthermore, the terminal definition management module's menu browsing submodule allows users to view the corresponding menu of the relay protection device for the terminal definition diagram corresponding to the factory default terminal definition. The terminal definition management module's printing submodule controls the relay protection device to print the terminal definition diagram corresponding to the factory default terminal definition. The terminal definition management module's remote reading submodule sends the terminal definition diagram corresponding to the factory default terminal definition via communication when performing remote reading.

[0047] Since the specific principle of the relay protection terminal definition management method in this embodiment has been described in detail in the above embodiment of the relay protection terminal definition management system, it will not be repeated here.

[0048] This invention has the following characteristics:

[0049] 1) The terminal definition editing module pops up a terminal definition modification prompt window to provide terminal definition editing prompts. The terminal definition editing module provides an editing information input interface. The terminal definition management module updates the modified terminal definition in the menu of the relay protection device involving the terminal definition. At the same time, it generates and saves the modified terminal definition file that is consistent with the actual project, thereby ensuring that the terminal definition in the relay protection device can be saved in a timely manner consistent with the actual terminal definition in the project.

[0050] 2) The terminal definition management function can be selected to use the terminal definition editing module. If the terminal definition is not used, the terminal definition editing module will be kept closed and the factory default terminal definition will be used as the current relay protection terminal definition. This ensures the basic function of the relay protection terminal definition and adapts to the working conditions where the factory default terminal definition is used and remains basically unchanged, as well as situations where there is no need to modify the terminal definition.

[0051] 3) The terminal definition management module provides terminal definition files corresponding to the factory default terminal definitions as well as terminal definition files generated in real time that are consistent with the actual engineering situation. Both types of terminal definition files are supported by menu browsing, device printing and remote reading through the terminal definition management module. They can be viewed in the relay protection device menu as terminal definition diagrams, printed directly through the device printing interface, and read remotely through communication. This provides maintenance personnel with accurate, fast and comprehensive terminal definition diagrams, improving the efficiency of equipment maintenance and troubleshooting.

[0052] It should be understood that the above-described specific embodiments of the present invention are merely illustrative or explanatory of the principles of the present invention, and do not constitute a limitation thereof.
