There is a great lag in the perception and control of network security risks in the substation operation and maintenance process. That is, there is a lack of real-time monitoring means, the scope of substation operation and maintenance security risk monitoring is too small, there is a lack of comprehensive analysis and assessment means of operation and maintenance security risks, and the dispatch master station lacks communication links to receive substation operation and maintenance security risk alarms and issue real-time commands to intercept operation and maintenance links.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0029] The monitoring, control, and data acquisition system in a substation is the core of the industrial control system, and its information security is related to the safe and stable operation of the entire industrial system.

[0030] Currently, during substation on-site operation and maintenance, the dispatch master station cannot conduct real-time network security monitoring of the substation operation and maintenance process, resulting in a significant lag in the perception and control of network security risks during substation operation and maintenance. The main problems are as follows: lack of real-time monitoring methods; insufficient scope of substation operation and maintenance security risk monitoring; lack of comprehensive analysis and assessment methods for operation and maintenance security risks; and lack of communication links at the dispatch master station to receive substation operation and maintenance security risk alarms and issue real-time commands to intercept operation and maintenance links.

[0031] To address the above problems, according to an embodiment of the present invention, a substation control system is provided. Figure 1 This is a schematic diagram of a substation control system provided according to an embodiment of the present invention, such as... Figure 1 As shown, the system includes: a dispatch master station 1, a server 2, substation equipment 3, a whitelist 4, a gateway 5, and a monitoring module 6. The dispatch master station 1 is signal-connected to the server 2. The dispatch master station 1 contains the whitelist 4, which is used to monitor the operation and maintenance status of the substation. The dispatch master station 1 includes: a centralized management platform 11 and an alarm module 12. The centralized management platform 11 and the alarm module 12 are signal-connected. The alarm module 12 reports abnormal operation and maintenance status to the centralized management platform 11 based on the whitelist 4. The dispatch master station 1 is equipped with a master control key 13, which is used to remotely disconnect the human-machine interaction link for substation operation and maintenance.

[0032] In this embodiment of the invention, a proactive protection approach is adopted for targets within the whitelist 4. This is achieved by setting up the whitelist 4 in the dispatch master station 1. The whitelist 4 is used to monitor the operation and maintenance of the substation. For example, a proactive defense system can be built based on the whitelist 4, establishing a whitelist protection strategy. The monitoring module 6 can monitor the substation equipment 3, and the dispatch master station 1 can judge the monitoring status of the substation equipment 3 by the monitoring module 6 based on the whitelist 4. For example, it can determine whether the current operation and maintenance uses a trustworthy program, data processing technology, etc., thereby achieving real-time monitoring based on the whitelist 4 during substation operation and maintenance, and conducting accurate and comprehensive security risk assessment and analysis. When the dispatch master station 1 detects a security risk, since the dispatch master station 1 is equipped with a centralized management platform 11 and an alarm module 12, and the centralized management platform 11 and the alarm module 12 are connected by a signal, the system will respond accordingly. Therefore, the alarm module 12 can feed back security risks (e.g., abnormal substation operation and maintenance situations) to the centralized management platform 11 based on the whitelist 4 and through the temporary wireless module to realize abnormal alarms. Then, the centralized management platform 11 can handle the current security risks. At the same time, the dispatch master station 1 is also equipped with a master control key 13, which is used to remotely disconnect the human-machine interaction link for substation operation and maintenance. Therefore, when a security risk or other abnormal situation occurs in the operation and maintenance of the substation, the master control key 13 can be used to directly issue real-time commands to intercept the operation and maintenance link, realize timely response and rapid handling of security risks or other abnormal situations, thereby establishing a human-machine security defense line in the substation, effectively ensuring the stability of substation operation and maintenance, and solving the technical problems of difficulty in real-time, accurate and large-scale security risk assessment and analysis for substation operation and maintenance, and difficulty in timely response to risk alarms.

[0033] Among them, the aforementioned monitoring module 6 can be a field monitoring module to ensure the real-time control of the system, and the gateway 5 can be a portable gateway. The portable gateway provides security functions such as two-factor authentication and authorized backup for operation and maintenance work, and takes the lead in realizing operation and maintenance security control in the industrial control field.

[0034] It should be noted that the aforementioned substation management and control system can be a substation management and control system based on whitelist operation and maintenance.

[0035] Figure 2 This is a schematic diagram of the position of the main control key 13 according to an embodiment of the present invention, wherein, Figure 2 The shaded area below represents the work surface of the visualization display terminal. By deploying the visualization display terminal, the main dispatch station 1 can report all command operations and abnormal action alarms during the operation and maintenance process to the centralized management platform, thereby achieving remote real-time monitoring at the operation level.

[0036] Figure 3This is a schematic diagram of the main control key 13 provided according to an embodiment of the present invention. Figure 1 ,like Figure 3 As shown, in an optional embodiment, the main control key 13 includes: a key shell 1301 and a hollow strip 1302; an anti-misoperation rod 1303 is provided inside the hollow strip 1302, wherein the anti-misoperation rod 1303 includes: a spring 1303_1 and an electromagnetic plate 1303_2; one end of the spring 1303_1 is fixedly connected to the inner wall of the hollow strip 1302 away from the key shell 1301, and the other end of the spring 1303_1 is fixedly connected to the electromagnetic plate 1303_2; a limiting hole 1304 is provided on the side wall of the key shell 1301, wherein the limiting hole 1304 is used for one end of the electromagnetic plate 1303_2 to extend into the interior of the key shell 1301 through the limiting hole 1304; wherein the electromagnetic plate 1303_2 is electrically connected to the dispatch master station 1.

[0037] Since the main control key 13 can remotely disconnect the human-machine interaction link for substation operation and maintenance with one click, in order to ensure that the operation and maintenance process can proceed smoothly under normal working conditions without being affected by accidental touch of the main control key 13, the embodiment of the present invention is provided with the aforementioned hollow strip 1302 and anti-accidental touch rod 1303. Based on the above-mentioned arrangement of the spring 1303_1 and electromagnetic plate 1303_2 in the anti-accidental touch rod 1303, the electromagnetic plate 1303_2 can be pulled by electromagnetic polarity and / or spring force to change its position within the hollow strip 1302. At the same time, the embodiment of the present invention provides on the side wall of the button shell 1301 of the main control key 13 A limiting hole 1304 is provided, and the cross-section of the electromagnetic plate 1303_2 of the limiting hole 1304 is matched. That is, when the electromagnetic plate 1303_2 moves under the traction of electromagnetic polarity and / or spring force, it can just pass through the limiting hole 1304, so that the end of the electromagnetic plate 1303_2 away from the spring 1303_1 extends into the interior of the button shell 1301, thereby locking the main control key 13 and preventing it from being pressed, so as to avoid accidental touch of the main control key 13. This effectively ensures that the human-machine interaction chain is not easily blocked due to accidental touch during normal operation of the substation, and thus effectively ensures the stability of human-machine interaction under the condition of conforming to whitelist 4.

[0038] It should be noted that the number and arrangement of the aforementioned anti-accidental touch levers 1303 can be specifically set according to actual application needs.

[0039] As an optional embodiment, the anti-accidental touch rod 1303 includes: two horizontal anti-accidental touch rods and two vertical anti-accidental touch rods, wherein the energized / de-energized states of the horizontal and vertical anti-accidental touch rods are opposite; in the energized state, the electromagnetic plates in the two horizontal anti-accidental touch rods attract each other, and the electromagnetic plates in the two vertical anti-accidental touch rods repel each other; the springs in the horizontal anti-accidental touch rods are tension springs, and the springs in the vertical anti-accidental touch rods are compression springs.

[0040] Figure 4 This is a schematic diagram of the master control key 13 in a self-locking state according to an embodiment of the present invention. Figure 5 This is a schematic diagram of the main control key 13 in the self-locking state provided according to an embodiment of the present invention, as shown below. Figure 4 and Figure 5 As shown, the anti-misoperation rod 1303 in this embodiment of the invention can be arranged in a cross shape by two horizontal anti-misoperation rods and two vertical anti-misoperation rods. The energized / de-energized states of the horizontal and vertical anti-misoperation rods are opposite. Since the electromagnetic plate 1303_2 is electrically connected to the dispatching master station 1, the electromagnetic polarity between the electromagnetic plates in the horizontal and vertical anti-misoperation rods can be changed by changing the energized state of the horizontal and vertical anti-misoperation rods by the dispatching master station 1. This causes the opposing electromagnetic plates to exhibit an adsorption or repulsion state in the energized and de-energized states, so as to combine the elastic force of the springs in the horizontal and vertical anti-misoperation rods to change the position of the electromagnetic plates.

[0041] For example, when powered on, the electromagnetic plates inside the horizontal anti-mistouch levers attract each other, and the spring inside the horizontal anti-mistouch levers is a tension spring. At this time, the electromagnetic plates inside the two horizontal anti-mistouch levers will attract each other due to the magnetic attraction of their electrodes. That is, one end of the electromagnetic plate inside the horizontal anti-mistouch lever will extend into the button housing 1301, causing the main control key 13 to reach a self-locking state. When powered off, there is no longer a magnetic attraction between the electromagnetic plates inside the two horizontal anti-mistouch levers. Instead, they will be pushed back from inside the button housing 1301 into the hollow strip 1302 by the elastic force of the tension spring, completing the reset. At this time, the main control key 13 is no longer locked by the horizontal anti-mistouch levers. The movement principle of the vertical anti-mistouch lever is similar to that of the horizontal anti-mistouch lever, and will not be described further here.

[0042] The lengths of the spring 1303_1 and the electromagnetic plate 1303_2 need to satisfy the following: when one end of the electromagnetic plate 1303_2 extends into the button housing 1301, the other end of the electromagnetic plate 1303_2 is still outside the button housing 1301; when the electromagnetic plate 1303_2 retracts from the inside of the button housing 1301, the end of the electromagnetic plate 1303_2 away from the spring 1303_1 is outside the button housing 1301.

[0043] It should be noted that in this embodiment, the horizontal and vertical anti-misoperation levers are set to different on / off states, and the internal springs and electromagnetic plates are also of different types. This is to prevent the main control key 13 from being erroneously deactivated due to errors in changing the power supply state by changing the power supply state of the horizontal and vertical anti-misoperation levers separately. Alternatively, the on / off states of the horizontal and vertical anti-misoperation levers, as well as the internal springs and electromagnetic plates, can be uniformly set. For example, both the horizontal and vertical anti-misoperation levers can be set so that the electromagnetic plates attract each other when energized, and the internal springs are tension springs, etc.

[0044] It should be noted that the spring 1303_1 mentioned above can also be replaced by an electric push rod to control the movement of the electromagnetic plate 1303_2.

[0045] As an optional implementation, whitelist 4 uses TCP / IP as the transmission protocol and identifies network packets using a seven-tuple. Whitelist 4 uses TCP / IP as the transmission protocol for monitoring, control, and data acquisition systems, employing a seven-tuple method to reduce network attacks. This seven-tuple method consists of a bidirectional packet sequence of source MAC address, destination MAC address, source IP address, destination IP address, source port, destination port, and protocol type. Based on whitelist 4, trusted zones can be established to allow only trusted programs and data to run, proactively protecting whitelisted targets with the most effective protection methods. In substation on-site operation and maintenance, a proactive defense system based on whitelist technology can be built, establishing whitelist protection strategies and adding security protection functions to substation on-site operation and maintenance management.

[0046] It is worth noting that whitelist 4 must possess two attributes: First, its size must be controllable, as a list containing millions of records in a typical power system network would render transmission infeasible (uncontrollable); second, whitelist 4 must be stable, as frequent changes would require frequent updates, otherwise a large number of alarm messages would be generated. In the monitoring, control, and data acquisition system network, traffic is acquired, aggregated into connections, and then summarized into a list. A connection is any data packet containing the same seven-tuple, regardless of its source or destination. During the learning phase, an initial whitelist 4 list containing seven-tuples is obtained through analysis of the created list. After the whitelist 4 list is generated, it will be analyzed during the detection phase. All entries in the network that match the whitelist are considered legitimate, while those that do not match whitelist 4 generate alarms.

[0047] Figure 6 This is a schematic diagram of the main control key 13 provided according to an embodiment of the present invention. Figure 2 ,like Figure 6As shown, in an optional embodiment, the upper surface of the button housing 1301 is provided with a transparent hole 14 corresponding to the hollow strip 1302. A color-transmitting strip 15 is fixedly connected to the outside of the transparent hole 14, and a powder-filling mechanism 16 is fixedly connected to the inner wall of the transparent hole 14. The powder-filling mechanism 16, fixedly connected to the inner wall of the transparent hole 14, can change the color of the color-transmitting strip 15 when the alarm module 12 issues a safety alarm, thereby reminding the staff to press the main control button 13 in a timely manner.

[0048] Figure 7 This is a schematic diagram of the color-transparent strip 15 and the powder-pouring mechanism 16 provided according to an embodiment of the present invention, as shown below. Figure 7 As shown, in one optional embodiment, the translucent strip 15 includes: a translucent sheet 1501 and a submerged strip 1502; the submerged strip 1502 is fixed to the lower end of the translucent sheet 1501 and embedded in the button housing 1301. The translucent sheet 1501 and the submerged strip 1502 are hollow structures and remain connected. The interiors of the translucent sheet 1501 and the submerged strip 1502 are saturated with magnetic fluid 1503, and the submerged strip 1502 is made of opaque material. The translucent sheet 1501 is made of transparent material and can be configured as an arc-shaped structure, while the submerged strip 1502 is made of opaque material. Both the translucent sheet 1501 and the submerged strip 1502 are hollow structures and remain connected. Therefore, the magnetic fluid 1503 can flow inside the translucent sheet 1501 and the submerged strip 1502, and the color presented at the translucent sheet 1501 can be changed by the flow of the magnetic fluid 1503.

[0049] As an optional embodiment, the magnetic fluid 1503 is a mixture of colored magnetic powder and water, wherein the colored magnetic powder is magnetic powder with a surface coated with a water-insoluble colored paint. Since the magnetic fluid 1503 is a mixture of colored magnetic powder and water, combined with the arc-shaped structure of the transparent sheet 1501, the colored magnetic powder will deposit at the submerged strip 1502 under normal conditions, while the transparent sheet 1501 contains water. Because the submerged strip 1502 is opaque, under normal conditions, the transparent strip 15 will only appear transparent. Under abnormal conditions (e.g., when the alarm module 12 issues an alarm), the colored magnetic powder disperses from the submerged strip 1502 to the transparent sheet 1501, changing the color of the transparent sheet 1501 to indicate that the self-locking state of the main control key 13 has been released and it can be pressed. Furthermore, the submerged strip 1502 does not easily affect the color dispersion of the colored magnetic powder at the transparent sheet 1501.

[0050] Figure 8 This is a schematic diagram of the powder-pouring mechanism 16 in its working state according to an embodiment of the present invention, as shown below. Figure 8As shown, in an optional embodiment, the powder preparation mechanism 16 is located below the color-transmitting sheet 1501. The powder preparation mechanism 16 includes: an electric push rod 1601, a liquid exchange bladder 1602, and a liquid guide tube 1603. The fixed end of the electric push rod 1601 is fixedly connected to the color-absorbing strip 1502, and the extended end of the electric push rod 1601 is in contact with the surface of the liquid exchange bladder 1602. One end of the liquid guide tube 1603 is connected to the color-absorbing strip 1502, and the other end of the liquid guide tube 1603 is connected to the liquid exchange bladder 1602.

[0051] In this embodiment, the powder-dispersing mechanism 16 can be used to disperse colored magnetic powder from the sinking strip 1502 to the transparent sheet 1501. For example, when it is necessary to change the color of the transparent sheet 1501, the extension end of the electric push rod 1601 continuously extends and shortens to squeeze the liquid exchange bladder 1602. The magnetic liquid in the liquid exchange bladder 1602 is sprayed into the sinking strip 1502 through the liquid guide tube 1603 and disperses the colored magnetic powder deposited in the sinking strip 1502, so that the colored magnetic powder is dispersed to the transparent sheet 1501, and the transparent sheet 1501 shows obvious color change.

[0052] The water-insoluble colored coating sprayed onto the surface of the colored magnetic powder can be a bright color such as red or yellow to ensure that the color change of the transparent film 1501 is sufficiently noticeable and serves as a reminder to staff.

[0053] Figure 9 This is a schematic diagram of the fluid exchange bag 1602 provided according to an embodiment of the present invention, as shown below. Figure 9 As shown, in an optional embodiment, the fluid exchange bag 1602 includes: two breathing hemispheres 1602_1, and a positioning layer 1602_2 fixedly connected between the two breathing hemispheres; the connection point between the liquid guide tube 1603 and the fluid exchange bag 1602 is located in the positioning layer 1602_2. The breathing hemispheres 1602_1 are elastically sealed structures, while the positioning layer 1602_2 is a rigid structure. This configuration ensures that the electric push rod 1601 can effectively compress the fluid exchange bag 1602, causing the breathing hemispheres 1602_1 of the fluid exchange bag 1602 to undergo breathing-like deformation, promoting the flow of the magnetic fluid 1503 inside the color-transmitting sheet 1501 and the color-sediment strip 1502. During this process, the positioning layer 1602_2 can fix the positions of the two breathing hemispheres 1602_1 and the inlet of the liquid guide tube 1603.

[0054] In summary, the substation management and control system provided in this embodiment proactively implements defense by establishing trusted zones that allow only trusted programs and data to run. It uses the most effective protection methods to proactively protect the targets in whitelist 4. During substation on-site operation and maintenance, a proactive defense system is built based on whitelist technology, establishing whitelist protection strategies to add security protection functions to substation on-site operation and maintenance management. During substation on-site operation and maintenance, alarms are sent to the dispatch master station 1 for network security risks, enabling real-time blocking of security risks during substation operation and maintenance.
