[0026] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] According to an embodiment of the present invention, a five-defense logic evaluation method for a portable substation is provided. It should be noted that in the flowchart in the accompanying drawings, the steps shown therein can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] The following is an introduction to the five-defense logic evaluation method of the portable substation in an embodiment of the present invention.

[0030] Figure 1 is a flow chart of a five-defense logic evaluation method for a portable substation according to an embodiment of the present invention. Figure 1 As shown, the five-defense logic evaluation method of the portable substation may include the following steps:

[0031] Step S101, obtaining five-defense logic evaluation information of the portable substation.

[0032] In the technical solution provided in the above step S101 of the present invention, the five-defense logic evaluation information of the portable substation can be obtained. Among them, the five-defense logic evaluation information is used to characterize the operation logic of the portable substation that needs to be evaluated. The portable substation can be a typical substation with a 110 kilovolt (kV) double busbar connection. It should be noted that only an example of a portable substation is given here, and the type of the portable substation is not specifically limited.

[0033] Optionally, the five-protection logic evaluation information may be information for evaluating the five electrical protections. The five electrical protections include: "preventing the circuit breaker from opening and closing by mistake", "preventing the disconnector from opening and closing with load", "preventing the grounding wire (grounding switch) from being hung (closed) with power on", "preventing the circuit breaker from being closed with the grounding wire (grounding switch) on", and "preventing the circuit breaker from being accidentally entered with power on".

[0034] Optionally, the anti-error device of electrical equipment can effectively prevent misoperation, resulting in ground short circuit and equipment damage, and can also prevent operators from mistakenly entering the energized area, which is one of the important measures to ensure power safety. The five protections can be achieved through a series of technical means such as electrical interlocking, mechanical interlocking, program lock and microcomputer anti-error interlocking to improve the safety and reliability of the power system.

[0035] Step S102: Determine the target working state of the evaluation system of the portable substation based on the five-defense logic evaluation information.

[0036] In the technical solution provided in the above step S102 of the present invention, after obtaining the five-defense logic evaluation information, the target working state of the evaluation system of the portable substation at this time can be determined, wherein the target working state is used to characterize whether the evaluation system is in normal operation.

[0037] Optionally, Figure 2 is a schematic diagram of a five-defense logic evaluation system for a portable substation according to an embodiment of the present invention, such as Figure 2 As shown, the evaluation system includes: a main control board, a serial port cable and a serial port touch screen. The main control board is used to process the five-defense logic and control the screen display. The serial port cable has bidirectional data transmission and power supply functions. The serial port touch screen can be an input and output device and is a friendly human-computer interaction interface.

[0038] It should be noted that this is only a preferred implementation method for determining the target working state of the evaluation system of the portable substation, and does not specifically limit the process and method for determining the target working state of the evaluation system of the portable substation. As long as the method and process for determining the target working state of the evaluation system of the portable substation are based on the obtained five-defense logic evaluation information, they are within the protection scope of the present invention and will not be listed here.

[0039] Step S103, in response to the target working state being a normal operating state, selecting a target evaluation mode that matches the target working state from a plurality of evaluation modes of the evaluation system.

[0040] In the technical solution provided in the above step S103 of the present invention, after obtaining the target working state of the evaluation system, if the target working state of the evaluation system at this time is a normal operating state, it is necessary to select a target evaluation mode that matches the target working state from multiple evaluation modes of the evaluation system, wherein the target evaluation mode can be a mode that has been pre-set in the evaluation system, such as a practice mode, a sandbox mode, and an examination mode.

[0041] For example, based on the five-defense logic evaluation information obtained, it can be determined that the evaluation system at this time has been normally started and is in normal operation. Furthermore, from the multiple modes preset in the evaluation system, the target evaluation mode can be selected as the sandbox mode.

[0042] It should be noted that this is only a preferred implementation method for determining the target evaluation mode of the evaluation system, and does not specifically limit the process and method for determining the target evaluation mode of the evaluation system. As long as the evaluation system is in normal operation, the process and method for determining the target evaluation mode from the multiple evaluation modes of the evaluation system are within the protection scope of the present invention and will not be listed here.

[0043] Step S104, based on the target evaluation mode, the five-defense logic of the portable substation is evaluated to obtain the evaluation result.

[0044] In the technical solution provided in the above step S104 of the present invention, the five-defense logic of the portable substation can be evaluated according to the target evaluation mode obtained above to achieve the purpose of obtaining the evaluation result.

[0045] Optionally, the evaluation results are used to characterize the mastery of the five-defense logic by the target object of the portable substation. The target object may be an evaluation person of the portable substation, or a maintenance person of the portable substation, or a user, etc. It should be noted that only examples of the target object are given here.

[0046] For example, after selecting the sandbox mode as the target evaluation mode, the five-defense logic of the portable substation can be evaluated in this sandbox mode, and then the evaluation results can be obtained to further understand the learning status of the maintenance personnel of the portable substation on the five-defense logic related content.

[0047] In the above steps S101 to S104 of the present invention, the five-defense logic evaluation information of the portable substation is obtained, wherein the five-defense logic evaluation information is used to characterize the operating logic of the portable substation that needs to be evaluated; based on the five-defense logic evaluation information, the target working state of the evaluation system of the portable substation is determined, wherein the target working state is used to characterize whether the evaluation system is in a normal operating state; in response to the target working state being a normal operating state, a target evaluation mode that matches the target working state is selected from multiple evaluation modes of the evaluation system; based on the target evaluation mode, the five-defense logic of the portable substation is evaluated to obtain an evaluation result, wherein the evaluation result is used to characterize the mastery of the five-defense logic by the target object of the portable substation. That is to say, the embodiment of the present invention can first obtain the five-defense logic evaluation information of the portable substation, and then according to the five-defense logic evaluation information obtained above, it can determine the target working state used to characterize whether the evaluation system of the portable substation is in a normal operating state. If the target working state is a normal operating state, then the target evaluation mode that matches the target working state can be selected from the multiple evaluation modes of the evaluation system, and finally according to the target evaluation mode, the five-defense logic of the portable substation can be evaluated to achieve the purpose of obtaining the evaluation result. Considering that after determining the target working state of the evaluation system of the portable substation according to the five-defense logic evaluation information of the portable substation, when the target working state is a normal operating state, a target evaluation mode that matches the target working state can be selected, so that according to the target evaluation mode, the five-defense logic of the portable substation can be evaluated to obtain the evaluation result, thereby solving the technical problem that the five-defense logic of the portable substation cannot be effectively evaluated, and achieving the technical effect that the five-defense logic of the portable substation can be effectively evaluated.

[0048] The above method of this embodiment is further introduced below.

[0049] As an optional implementation method, based on the target evaluation mode, the five-defense logic of the portable substation is evaluated to obtain an evaluation result, including: in response to the target evaluation mode being the sandbox mode, generating an operation instruction for the target device of the portable substation; based on the operation instruction, detecting the five-defense logic of the target device to obtain the detection result of the target device, wherein the detection result is used to characterize whether the logic in the target device complies with the five-defense logic; based on the detection result, determining the evaluation result.

[0050] In this embodiment, after obtaining the target evaluation mode, if the target evaluation mode is the sandbox mode at this time, an operation instruction of the target device of the portable substation can be generated, and then according to the operation instruction, the five-defense logic of the target device can be tested to obtain the detection result of the target device, and based on the detection result obtained at this time, the purpose of determining the evaluation result can be achieved. Among them, the target device can be a preset device, such as a switch, a knife switch, etc.

[0051] Optionally, when the target evaluation mode is the sandbox mode, the evaluation system receives a click operation from the user and can generate an operation instruction for the target device, wherein the click operation is an operation of clicking an electrical symbol of the target device. For example, in the sandbox mode, the user can simulate operating the device by clicking the electrical symbol of the device.

[0052] Optionally, in response to the detection result that the logic in the target device complies with the five-defense logic, the evaluation system can directly implement the operation contained in the target device, thereby updating the logical state of the target device and determining that the evaluation result has passed the evaluation. For example, after simulating the operation of the target device, if the operation complies with the five-defense logic, the system implements it and changes the state of the device.

[0053] Optionally, in response to the detection result that the logic in the target device does not comply with the five-defense logic, the evaluation system issues a warning in the form of a pop-up window, and displays which of the five-defenses is violated, and determines that the evaluation result at this time is failed. Figure 3 is a schematic diagram of a pop-up window warning according to an embodiment of the present invention, such as Figure 3 As shown, after simulating the operation of the target device, if this operation violates the five-defense logic, a warning is given in the form of a pop-up window, and it is pointed out which of the five defenses is violated. For example, a pop-up window pops up in the display interface and displays a warning message: "Disconnect under load!".

[0054] As an optional implementation method, based on the target evaluation mode, the five-defense logic of the portable substation is evaluated to obtain an evaluation result, including: in response to the target evaluation mode being the practice mode, calling the operation ticket of the portable substation to obtain the first operation task of the portable substation; executing the first operation task to obtain the first execution result of the portable substation, wherein the first execution result is used to characterize the execution status of the five-defense logic of the portable substation; based on the first execution result, determining the evaluation result.

[0055] In this embodiment, after obtaining the target evaluation mode, if the target evaluation mode is a practice mode, the operation ticket of the portable substation can be called first, and then the first operation task of the portable substation can be obtained, and then the first operation task can be executed to obtain the first execution result of the portable substation. Finally, based on the first execution result obtained, the purpose of obtaining the evaluation result is achieved.

[0056] Optionally, the first operation task is an operation task corresponding to relevant content in the called operation ticket, for example, Figure 4 is a schematic diagram of an operation task according to an embodiment of the present invention, such as Figure 4 As shown, the operation tasks may be: switching from the first busbar (1M) operation to the second busbar (2M) operation, switching from hot standby to cold standby, switching from cold standby to maintenance, switching from cold standby to maintenance, switching from 1M hot standby to 2M hot standby, switching from cold standby to hot standby, switching from maintenance to cold standby, and switching from maintenance to cold standby, etc. It should be noted that only the first operation task is exemplified here.

[0057] For example, users can first select an operation task, which is adapted from the typical operation ticket of the substation, including representative switching operations such as hot reversing busbar, cold reversing busbar and main transformer load transfer in the double busbar connection, and then execute the selected operation task, so that users can not only learn the five-protection logic, but also become familiar with the content and steps of the substation switch operation.

[0058] As an optional implementation method, executing the first operation task to obtain the first execution result of the portable substation includes: based on the first operation task, using the evaluation system to generate prompt information of the first operation task; based on the prompt information, determining the first execution result.

[0059] In this embodiment, after the first operation task is obtained, the evaluation system can be used to generate prompt information of the first operation task, and then the purpose of determining the first execution result is achieved according to the prompt information.

[0060] Optionally, the prompt information is used to prompt a first target operation to be performed for the first operation task. The first target operation may be an operation of each step to be performed during the execution of the first operation task.

[0061] For example, in the practice mode, after selecting an operation task, the device status in the primary wiring diagram can be adjusted to the corresponding status preset for the operation task, and the screen will prompt the next operation to be performed.

[0062] As an optional implementation method, based on the target evaluation mode, the five-defense logic of the portable substation is evaluated to obtain an evaluation result, including: in response to the target evaluation mode being the test mode, generating a second operation task of the portable substation; executing the second operation task to obtain a second execution result of the portable substation, wherein the second execution result is used to characterize whether the second target operation to be performed by the second operation task complies with the five-defense logic; based on the second execution result, determining the evaluation result.

[0063] In this embodiment, if the target evaluation mode obtained is the test mode, a second operation task of the portable substation can be generated, and then the second operation task can be executed to obtain a second execution result of the portable substation. Based on the second execution result obtained above, the purpose of determining the evaluation result can be achieved.

[0064] Optionally, the second operation task can be the same task as the first operation task, for example, switching from the first bus (1M) operation to the second bus (2M) operation, from hot standby to cold standby, from cold standby to maintenance, from cold standby to maintenance, from 1M hot standby to 2M hot standby, from cold standby to hot standby, from maintenance to cold standby, and from maintenance to cold standby, etc.

[0065] Optionally, the second operation task may also be a task corresponding to the five-defense logic, such as opening the switch with load, closing the switch with load, closing the switch with power on, closing the switch with the switch on, and going to the wrong interval, etc. It should be noted that only an example is given here to illustrate the second operation task, and the name of the second operation task is not specifically limited.

[0066] Optionally, after obtaining the second execution result, if the second execution result is that the second target operation required to be executed for the second operation task complies with the five-prevention logic, then the evaluation result can be determined as having passed the evaluation; if the second execution result is that the second target operation required to be executed for the second operation task does not comply with the five-prevention logic, then the evaluation result can be determined as having failed the evaluation.

[0067] As an optional implementation method, executing a second operation task and obtaining a second execution result of the portable substation includes: obtaining an initial execution state of the second operation task, wherein the initial execution state is used to characterize that the second operation task is in a start execution state; based on the initial execution state, executing the second operation task and determining a target execution time of the second operation task; based on the target execution time, determining a target execution state of the second operation task, wherein the target execution state is used to characterize that the second operation task is in an execution completion state; based on the target execution state, determining a second execution result.

[0068] In this embodiment, an initial execution state used to characterize that the second operation task is in a starting execution state can be obtained first, and the second operation task can be executed according to the initial execution state, so that the target execution time of the second operation task can be determined. Then, according to the target execution time, the target execution state used to characterize that the second operation task is in an execution completion state at this time can be determined. Finally, according to the target execution state obtained above, the second execution result can be determined.

[0069] Optionally, the target execution time may be the time required to complete the execution of the second operation task, referred to as the execution time, for example, 4 minutes and 45 seconds. After the target execution time is obtained, the target execution time may be displayed on the interface using the evaluation system.

[0070] As an optional implementation method, an evaluation result is determined based on the second execution result, including: in response to the second execution result being that the second target operation does not comply with the five-defense logic, the number of operations of the second target operation is updated to obtain the target number of operations for the second operation task; based on the target number of operations, the evaluation result is determined.

[0071] In this embodiment, after obtaining the second execution result, if the second target operation does not comply with the five-defense logic, the operation times of the second target operation need to be updated, and the target operation times of the second operation task can be obtained, and then the evaluation result can be determined based on the target operation times.

[0072] Optionally, the number of operations may be the number of erroneous operations, referred to as the number of erroneous operations for short, and the target number of operations may be the updated number of erroneous operations, that is, the total number of erroneous operations, for example, 16.

[0073] For example, Figure 5 is a schematic diagram of a display interface of an examination mode according to an embodiment of the present invention, such as Figure 5 As shown, the total number of erroneous operations is 16, the time taken is 04:45, the number of erroneous operations of the load opening task is 5, the number of erroneous operations of the load closing task is 4, the number of erroneous operations of the live earthing switch task is 0, the number of erroneous operations of the earthing switch closing task is 6, and the number of erroneous operations of the wrong interval task is 1.

[0074] For another example, the test mode is similar to the practice mode, but there will be no operation prompts on the screen, and users need to complete the switching operation task based on their own knowledge and experience. If the operation violates the five-defense logic, the system will no longer pop up a window prompt, but will record the number of wrong operations. When the user completes the operation task, the system will display the time taken for the operation and the number of various wrong operations on the settlement page.

[0075] As an optional implementation method, determining the evaluation result based on the target number of operations includes: evaluating the second execution result based on the target number of operations to obtain an evaluation score for the second execution result; and determining the evaluation result based on the evaluation score.

[0076] In this embodiment, after obtaining the target number of operations, the second execution result can be evaluated to obtain the evaluation score of the second execution result, and the final evaluation result can be determined by using the evaluation score. The evaluation score can be determined according to the target number of operations and the target execution time. For example, Figure 5 As shown, the examiner can score the student's test based on this, thus achieving the purpose of obtaining the assessment results.

[0077] In this embodiment, the five-defense logic evaluation information of the portable substation can be obtained first, and then based on the five-defense logic evaluation information obtained above, the target working state used to characterize whether the evaluation system of the portable substation is in a normal operating state can be determined. If the target working state is a normal operating state, a target evaluation mode that matches the target working state can be selected from multiple evaluation modes of the evaluation system. Finally, according to the target evaluation mode, the five-defense logic of the portable substation can be evaluated to achieve the purpose of obtaining the evaluation result. Considering that after determining the target working state of the evaluation system of the portable substation according to the five-defense logic evaluation information of the portable substation, when the target working state is a normal operating state, a target evaluation mode that matches the target working state can be selected, so that according to the target evaluation mode, the five-defense logic of the portable substation can be evaluated to obtain the evaluation result, thereby solving the technical problem that the five-defense logic of the portable substation cannot be effectively evaluated, and achieving the technical effect that the five-defense logic of the portable substation can be effectively evaluated.

[0078] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0079] The five-defense system is an important device for preventing misoperation in a substation. Any normal switching operation must be simulated and judged by the five-defense system, so as to effectively prevent human misoperation and power grid accidents. It is crucial to the safe operation of the substation and even the stability and reliability of the power grid. The five-defense logic of the substation is realized through a microcomputer anti-misoperation locking device, which displays the electrical connection relationship and real-time status of each power equipment with a primary wiring diagram of the entire station.

[0080] At present, each switching operation of a portable substation must be verified on a five-protection machine before it can be carried out. Therefore, each operator of a portable substation must understand the five-protection logic and master the operation of the five-protection machine. However, conducting evaluation exercises on the five-protection machine will not only affect the normal operating tasks of the portable substation, but may also have unpredictable consequences on the five-protection locking system and even electrical equipment in the station, resulting in technical problems that make it impossible to effectively evaluate the five-protection logic of the portable substation.

[0081] Therefore, in order to solve the above problems, the present invention proposes a five-defense logic evaluation method for a portable substation, which can first obtain the five-defense logic evaluation information of the portable substation, and then determine the target working state used to characterize whether the evaluation system of the portable substation is in a normal operating state according to the five-defense logic evaluation information obtained above. If the target working state is a normal operating state, a target evaluation mode that matches the target working state can be selected from multiple evaluation modes of the evaluation system, and finally, according to the target evaluation mode, the five-defense logic of the portable substation can be evaluated to achieve the purpose of obtaining the evaluation result. Considering that after determining the target working state of the evaluation system of the portable substation according to the five-defense logic evaluation information of the portable substation, when the target working state is a normal operating state, a target evaluation mode that matches the target working state can be selected, so that according to the target evaluation mode, the five-defense logic of the portable substation is evaluated to obtain the evaluation result, thereby solving the technical problem that the five-defense logic of the portable substation cannot be effectively evaluated, and achieving the technical effect that the five-defense logic of the portable substation can be effectively evaluated.

[0082] In this embodiment, a training device that integrates the five-protection logic of various primary equipment in a typical substation can be proposed. The device is used for substation operators to deeply learn the relevant knowledge of the five-protection logic of each primary equipment in various states. It can simulate the separation and connection state of the primary equipment and the judgment results of the relevant locking logic, and display the judgment results.

[0083] Optionally, the device can achieve the following goals: the device is not connected to the actual electrical equipment and the anti-mistake locking device, but abstracts the station equipment to be simulated into a primary wiring diagram, and judges the locking relationship between the devices through the built-in five-protection logic table. If the input operation does not conform to the five-protection logic, the operation will not be performed and a warning will be given; in order to facilitate experts and lecturers to carry it with them for on-site training, the device must be light enough, and the size and weight should not be greater than a laptop. And it can be powered by batteries so that training can be carried out anytime and anywhere indoors and outdoors; the device should reserve an external communication interface to connect various extended peripherals, such as simulated electrical equipment, five-protection keys, etc., to realize the five-protection logic outside the screen, and deepen the trainees' understanding of the anti-mistake locking operation; the device should reserve a program download interface to upgrade and maintain the built-in software later, and can also realize personalized customization functions by replacing the software without changing the hardware.

[0084] In this embodiment, the training device may be a device constructed by an evaluation system, wherein, as described above, Figure 2 As shown, the evaluation system includes: a main control board, a serial port cable and a serial port touch screen. The main control board is used to process the five-defense logic and control the screen display. The serial port cable has bidirectional data transmission and power supply functions. The serial port touch screen can be an input and output device and is a friendly human-computer interaction interface.

[0085] Optionally, the device uses an integrated serial touch screen as an input and output device, and all operations are implemented through the touch screen, with a friendly human-computer interaction interface. Through the development tools supporting the serial screen, the image display and touch feedback functions can be easily realized, greatly shortening the development time. After the user touches a specific area on the screen, the serial screen will upload the touch information to the single-chip microcomputer on the main control board through the serial interface. The single-chip microcomputer analyzes and processes the input information in combination with the current state of the system, and then controls the display content of the screen through the serial interface. The serial touch screen and the single-chip microcomputer main control board constitute a simple and efficient embedded system. The serial screen is equivalent to the computer display, and the single-chip microcomputer integrates the components of the computer motherboard such as the central processing unit (CPU), memory, program / data storage, and input and output (IO) ports.

[0086] In this embodiment, a typical substation with 110kV double busbar connection is taken as the basis, and the five-defense logic of all primary equipment such as switches and circuit breakers in the substation is demonstrated through the primary wiring in the typical substation model. On this basis, three modes different from the previous five-defense computers, namely "sandbox mode", "practice mode" and "exam mode", are developed specifically for the training needs of the five-defense.

[0087] Optionally, in the sandbox mode, the user can simulate the operation of the device by clicking on the electrical symbol of the device. If this operation complies with the five-defense logic, the system will implement it and change the status of the device. Figure 3 As shown, after simulating the operation of the target device, if this operation violates the five-defense logic, a warning will be given in the form of a pop-up window, and it will be pointed out which specific one of the five defenses has been violated.

[0088] Optionally, the practice mode is similar to the exam mode, where the user can first select an operation task, e.g. Figure 4 As shown, these operation tasks are adapted from typical operation tickets of substations, including representative switching operations such as hot busbar reversing, cold busbar reversing and main transformer load transfer in double busbar connection, and then executing the selected operation tasks, so that users can not only learn the five-defense logic, but also become familiar with the content and steps of substation switch operation.

[0089] For example, in the practice mode, after selecting an operation task, the device status in the primary wiring diagram can be adjusted to the corresponding status preset for the operation task, and the screen will prompt the next operation to be performed.

[0090] Optionally, the test mode is similar to the practice mode, but there will be no operation prompts on the screen, and the user needs to complete the switching operation task based on his or her own knowledge and experience. If the operation violates the five-defense logic, the system will no longer pop up a window prompt, but will record the number of wrong operations. When the user completes the operation task, the system will display the time taken for the operation and the number of various wrong operations on the settlement page, such as Figure 5 As shown, the examiner can use this to mark the student's exam.

[0091] In this embodiment, the five-defense logic evaluation information of the portable substation can be obtained first, and then based on the five-defense logic evaluation information obtained above, the target working state used to characterize whether the evaluation system of the portable substation is in a normal operating state can be determined. If the target working state is a normal operating state, a target evaluation mode that matches the target working state can be selected from multiple evaluation modes of the evaluation system. Finally, according to the target evaluation mode, the five-defense logic of the portable substation can be evaluated to achieve the purpose of obtaining the evaluation result. Considering that after determining the target working state of the evaluation system of the portable substation according to the five-defense logic evaluation information of the portable substation, when the target working state is a normal operating state, a target evaluation mode that matches the target working state can be selected, so that according to the target evaluation mode, the five-defense logic of the portable substation can be evaluated to obtain the evaluation result, thereby solving the technical problem that the five-defense logic of the portable substation cannot be effectively evaluated, and achieving the technical effect that the five-defense logic of the portable substation can be effectively evaluated.
