Before starting the operation, the incoming line verification simulation rehearsal should be performed on the simulation diagram, and the operation can be carried out after it is correct. Therefore, in addition to the equipment that is consistent with the actual operation mode, the substation simulation screen also needs to have a simulation rehearsal function to prevent errors.

However, the present application can be implemented in many other ways different from the following description.

[0031] It should be noted that the terms "first", "second", "third", etc. in the claims, description and drawings of the present application are used to distinguish similar objects and are not used to describe a specific order or sequence. The data used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0032] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "set" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection. It can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] The present embodiment provides a substation operation and maintenance simulation anti-error operation system. The structure and working principle of the substation operation and maintenance simulation anti-error operation system of the present embodiment are described below using a specific embodiment. It should be noted that the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application. The following is a detailed introduction to what is involved in this application.

[0034] The substation simulation training system uses advanced computer technology and refers to the scene on site to simulate all operating equipment and systems in detail. The substation operation and maintenance simulation anti-error operation system is also a substation simulation (training) system, which can show the trainees all kinds of abnormalities or faults that occur in the power grid. These faults are often difficult for operators to encounter, and the traditional master-apprentice training method is difficult to achieve. Through repeated training of operators, their normal operation and accident handling capabilities are improved. The substation simulation training system can not only greatly improve the technical quality and work ability of operators, efficiently and safely train qualified substation operators, but also become a powerful tool for anti-accident measures.

[0035] There are many electrical equipment in the power system, which can usually be divided into primary electrical equipment and secondary electrical equipment. The primary equipment refers to the equipment that directly produces, transmits, distributes and uses electrical energy. They are interconnected to form the main electrical circuit of power generation, transmission and distribution.

[0036] Electrical primary equipment refers to electrical equipment that is directly used to produce, transform, transmit, guide, distribute and use electrical energy. Primary equipment is the on-site high-voltage equipment.

[0037] Electrical secondary equipment refers to low-voltage electrical equipment that monitors, controls, regulates, and protects the operation of primary equipment and provides operating conditions or production command signals to operators and maintenance personnel. With the intelligent management of power grids, the types of secondary equipment are increasing, and they tend to be integrated (primary equipment comes with secondary equipment when it leaves the factory).

[0038] Substation primary equipment: transformer, circuit breaker, disconnector, grounding switch, voltage transformer, current transformer, capacitor, reactor, wave trap, GIS combination electrical appliances, busbar, lightning arrester, coupling capacitor, transformer and other primary equipment and their operation control mechanism. Substation secondary equipment: control panel, simulation panel, central signal panel, protection and automatic device panel, telecontrol panel, AC / DC panel, meter panel, and other device group panel and their operation control mechanism.

[0039] The working principle of the five-prevention system is to simulate the rehearsal operation on the anti-error host before switching operation. The anti-error host makes a locking logic judgment for each simulated operation based on the pre-stored anti-error locking logic library and the current equipment position status, and generates the actual operation program based on the correct simulated operation content and transmits it to the computer key. The operator opens the corresponding coded lock in turn according to the operation content displayed by the computer key to operate the equipment. After all operations are completed, the computer key is sent back to keep the equipment status consistent with the equipment status on site.

[0040] The "five protections" in switching operations refer to preventing the switch from being pulled or closed by mistake; preventing the disconnector from being pulled or closed under load; preventing the grounding wire from being hung or the grounding disconnector from being closed under power; preventing the grounding wire from being closed under power or the grounding disconnector from being closed; and preventing entering the live interval by mistake.

[0041] The operation process of substation operation and maintenance at the work site can be divided into four links, namely, five-protection system operation, primary equipment switching operation, secondary equipment operation, and safety measures deployment. Errors in any link may lead to electrical misoperation, which will directly threaten the safety of people and power grid equipment.

[0042] Therefore, it is imperative to develop an integrated training simulation system to connect the substation operation and maintenance anti-misoperation five-prevention system training module with the research and development safety measures deployment device training module. The substation operation and maintenance simulation anti-misoperation system is highly integrated, and all training (rehearsal) modules are concentrated on one system. The training (rehearsal) personnel can directly conduct anti-misoperation training that is more in line with the on-site primary and secondary equipment operation scenarios, improve the training effect, and be more convenient.

[0043] The substation operation and maintenance simulation anti-error operation system provided in the embodiment of the present application requires first building a simulation operation screen for the primary and secondary equipment in the entire room.

[0044] According to the requirements of the simulation operation of the primary equipment in the whole room and the verified primary wiring diagram, the simulation screen is designed. The simulation screen needs to meet the full restoration of the primary wiring diagram, meet the availability of the equipment operation simulation, and be able to penetrate and connect with the primary and secondary equipment simulation tools.

[0045] After completing the construction of the simulated operation screens for primary and secondary equipment throughout the room, the five-defense training system and the deployment of safety measures are integrated into a whole.

[0046] Please see Figure 4 , Figure 4The schematic diagram of the equipment connection relationship of the substation operation and maintenance simulation anti-misoperation system provided in the embodiment of the present application can better understand the equipment connection relationship in the following content. In the training main control room, equipment such as the five-protection system workstation 401, the protection measurement and control acquisition device 403 (protection measurement and control device), and the equipment simulation operation screen 404 can be added. The primary and secondary equipment (such as pressure plates, etc.) in the relay protection room of the mixed simulation training room are modified and connected to the protection measurement and control device, and the protection measurement and control device receives the remote signals of the primary and secondary equipment. The protection measurement and control device is interfaced with the 402 monitoring host and the simulation screen, and the monitoring host collects the status information of the primary and secondary equipment through the protection measurement and control device. On this basis, electrical operation evaluation workstations, monitoring workstations, and data servers can also be added to improve the automated training system. The focus of this application is to protect the through-design structure of the five-protection workstation and the safety measures deployment device.

[0047] Safety measures deployment refers to the use of fences, shields, covers, boxes and other equipment to isolate the live body from the outside world, prevent the human body from touching or approaching the live body, so as to avoid accidents such as electric shock or arc injury. Shielding devices are divided into two types according to their use time: one is a permanent shielding device, such as the fence of the distribution device, the protective net of the busbar, etc.; the other is a temporary shielding device, usually referring to the temporary fence used in maintenance work. Shielding devices are mainly used on the movable parts of protective switching electrical appliances and high-voltage equipment. In order to prevent casualties, shielding safety measures should be used in conjunction with other safety measures.

[0048] The embodiment of the present application provides a substation operation and maintenance simulation error prevention operation system, including a simulated equipment operation screen simulating primary and secondary equipment of a substation, a protection and measurement control device that receives and sends simulated quantities of primary and secondary equipment through network communication, a monitoring host that monitors the analog quantities sent by each protection and measurement control device through network communication, a five-defense workstation for staff to rehearse various primary and secondary equipment operation data, and a safety measures deployment device. The equipment simulation operation screen is used to realize the operation simulation of the on-site equipment operation scene. The surface of the equipment simulation operation screen has an etched circuit. At each simulated equipment button, the etched circuit has a knob that turns on or off the equipment button. The safety measures deployment device includes holes set around the equipment on the equipment simulation operation screen, simulated fences set in the holes, and simulated enclosures set by the simulated fences. In the case where the display screen area is too large, the local circuit of the equipment switch can be simulated in the etched part, and then the circuit is connected by a wire.

[0049] Please see Figure 2-1 and Figure 2-2 , Figure 2-1 and Figure 2-2 They are respectively a top view and a side view of the knob connection provided by the substation operation and maintenance simulation anti-misoperation system provided by the embodiment of the present application. Figure 1 and Figure 2-1 It can be seen that the knob is set on the device simulation operation screen, and the etching wire on the device operation simulation screen is connected to the nearby device by setting the knob and the etching wire. The etching wire has a knob for turning on or off the device button. The knob includes Figure 2-1 When the knob is turned, the connection state of the etched wire will change, which in turn affects the connection state between the device and the etched wire: When the conductive copper electrode is in Figure 2-1 When the conductive copper electrode is in the middle position, the etching copper wire is disconnected in the middle, causing the etching wire and the device to be disconnected. Even if the operator accidentally touches the device button at this time, it will not affect the normal operation; when the conductive copper electrode is in a horizontal state, the etching copper wire is turned on, and the device and the etching wire are also turned on. Therefore, the knob of this application can be used to control the on and off of the device, which reduces the accidental touch of the button of the simulated device, improves the safety of the trainees, and reduces the possibility of accidental touch. Figure 2-2 The shape of the knob as seen from the side of the device's simulated operation screen is clearly shown. For easy operation, the handle is provided with a protrusion, which makes it easier to rotate and correctly distinguish the direction of screwing.

[0050] Please combine Figure 1 , Figure 3 and Figure 5 Understand this part. Figure 3 This is a schematic diagram of a scenario of a safety measure deployment device for a substation operation and maintenance simulation anti-misoperation system provided by an embodiment of the present application. Figure 1 It is a schematic diagram of the equipment connection relationship of the safety measure deployment device provided by the substation operation and maintenance simulation anti-misoperation system provided in the embodiment of the present application. Figure 1 The entire structure is displayed on the equipment simulation operation screen, which not only includes the corresponding equipment on site, but also includes the connection relationship between the equipment, such as Figure 1 104, 105, these connection relationships are reflected by etching lines 103, 108 on the device simulation operation screen. The etching lines can reflect the positional relationship of the devices to some extent, so the positions of the devices to be enclosed and their holes 106, 107 can be determined according to the etching lines. Figure 3 It shows more concretely how the security measures deployment device is reflected on the equipment simulation operation screen in actual scenarios.

[0051] Preferably, the equipment simulation operation screen includes on-site wiring conditions of primary equipment and secondary equipment, and the wiring conditions are reflected by etching lines on the equipment simulation operation screen.

[0052] The position of the hole is determined by the distance between the device buttons (such as 101 and 102) located in the same row or column, for example, Figure 11011 and 1021 are buttons in the same row, and the distance between the dotted lines of 1011 and 1021 is the distance between the device buttons, and the position of the etching circuit is determined. Generally, it is possible to flexibly decide where the holes should be set according to the actual situation of the device connection on the simulated operation screen.

[0053] In this embodiment, the hole settings are displayed in an optimal manner. On the device simulation operation screen, the position of the hole is determined by the distance between the device buttons in the same row or column, and the position of the etching circuit, including: the hole position is the middle of two parallel etching circuits, or the hole position is the center of an inscribed circle drawn with a certain radius between two perpendicular etching circuits; wherein the certain radius is one quarter to one half of the distance between the device buttons in the same row or column. For details, please refer to Figure 5 , Figure 5 Schematic diagram of the hole positions of the substation operation and maintenance simulation anti-misoperation system provided in the embodiment of the present application. Among them, 1011 and 1021 are buttons in the same row. For example, the radius here is one-fourth of the distance between 1011 and 1021 and one-fourth of the length of the dotted line between 1011 and 1021 in the figure; 1081 and 1031 are two mutually perpendicular etching lines. The inscribed circle can be jointly determined based on the etching lines 1081 and 1031. Figure 5 The dotted circle in the figure, and the center of the circle is the optimal position of the hole determined here.

[0054] Specifically, the holes that should be set around the devices on the device simulation operation screen are: on the device simulation operation screen, there are some devices located in the same row and some devices located in the same column, and these devices usually contain operable knife switch buttons. In this embodiment, the distance between the knife switch buttons located in the same row or column can be obtained first, and the required radius is greater than one quarter of the distance and less than one half of the distance. This length can be used to draw an inscribed circle between two vertical etching lines as an aid, so that the center of the inscribed circle can be used to determine the best hole position to be set. Between two parallel etching lines, the best hole position is selected to be set in the middle of the two parallel etching lines. The above settings can prevent users from making erroneous operations on the enclosed area on the device simulation display screen.

[0055] After the holes are set, a simulated fence rod can be inserted into the holes according to the requirements of security measures. The simulated fence rod set in the holes includes a hard rod-shaped object inserted into the holes and matching the specifications of the holes.

[0056] Exemplarily, the hole can be a circular hole, or any other shape required by experience, and the cross-sectional shape of the corresponding hard rod-shaped object is also corresponding thereto. The hard rod-shaped object can be a wooden stick, a special simulated fence rod, or other strip-shaped object that can be inserted into the hole and has a certain hardness. These simulated fence rods are mainly used to schematically separate the enclosed equipment from the external space to prevent unauthorized personnel from approaching the equipment. However, only setting holes and fence rods is not effective enough in actual protection. Therefore, on this basis, some soft strips can be fixed on the simulated fence rods to enhance protection.

[0057] The simulated fence set up by the simulated fence rod includes the simulated fence rod, the hole and the fence formed on the simulated fence rod by using a soft belt.

[0058] In the simulation system, the soft belt-like object can be a rope, a cloth belt, a ribbon, or a special simulated fence. The specific material can be obtained locally or selected according to needs, and this application does not limit this.

[0059] The safety measures deployment device includes a signboard set on the simulated enclosure. On the basis of the above protection facilities, a corresponding small signboard can be set on the connected simulated enclosure to clearly and directly reflect the content to be announced on the signboard, so as to better achieve the purpose of safety protection.

[0060] Through the above steps, the setting of the safety measures deployment device in the substation operation and maintenance simulation anti-error operation system is completed. The above embodiment combines the five-defense system with the safety measures deployment device. By setting holes on the simulation operation screen, the purpose of simulating the safety measures deployment device is achieved, and the existing substation operation and maintenance simulation anti-error operation system is improved.

[0061] According to the steps mentioned above, the on-site substation operation and maintenance operation process must also integrate the five-defense system operation, the deployment of safety measures, the primary equipment switching operation, and the secondary equipment startup and shutdown operation.

[0062] Preferably, the data transmitted in the connection between the monitoring host and the protection and measurement control device and the equipment simulation operation screen includes the collected status information of the primary and secondary equipment.

[0063] The five-defense workstation is installed with five-defense operating system software and communication software, and simulates the training mode workflow: simulation, printing, subpoena, primary and secondary equipment operation, feedback, security measures deployment, data maintenance, etc. The platform is based on the server, and all operating status information is converted into analog quantity through electrical quantity and transmitted back to the server, and used as the information display terminal at the monitoring workstation.

[0064] According to the substation operation and maintenance simulation anti-misoperation system provided by the above embodiment of the present application, the safety measure deployment device is integrated with the five-prevention operation system, so that the functions and data display of the substation operation and maintenance professional anti-electrical misoperation system are more complete and its intelligence and integration level are improved, so as to efficiently achieve the effects of practical training and simulation rehearsal.

[0065] It should be noted that, although several structures, components or units for realizing related functions are mentioned in the above detailed description, such division is not mandatory. In fact, according to the specific implementation of the present application, the features and functions of two or more structures, components or units described above can be concretized in one structure, component or unit. Conversely, the features and functions of one structure, component or unit described above can be further divided into multiple components, structures or units to be concretized.

[0066] In addition, although the components and the installation methods of the components or devices in the present application are described in a specific order in the drawings, this does not require or imply that the components or devices must be designed according to the specific components or the installation methods of the components, or that all the components shown must be included to achieve the desired results. Additionally or alternatively, some components can be omitted, multiple components can be combined into one component to achieve corresponding functions, and / or one component can be decomposed into multiple components to achieve corresponding functions, etc.

[0067] Although the present application is disclosed as above in the form of a preferred embodiment, it is not intended to limit the present application. Any technical personnel in this field may make possible changes and modifications without departing from the spirit and scope of the present application. Therefore, the scope of protection of the present application shall be based on the scope defined by the claims of the present application.
