[0002] To enable the scientific formulation of production plans based on dynamic electricity market conditions, smart power plants have emerged. To ensure safe production, smart power plants must implement measures to prevent misoperation and avoid safety accidents caused by such errors.

[0003] Cloud computing is a model for providing computing resources and services via the internet. Cloud servers integrate computing resources, storage resources, and application services through virtualization technology and provide them to users via the internet. Users can acquire and release these resources at any time as needed, without having to worry about the underlying hardware and infrastructure.

[0004] Existing smart power plants use cloud computing for centralized management to prevent misoperation. However, for scenarios with high real-time requirements, placing the computation on cloud servers can cause negative impacts such as longer network latency, network congestion, and reduced service quality. In wireless application scenarios, there are also network outages, which affect related business applications. Furthermore, if the computation is performed on terminal devices, the computing power of terminal devices is generally lower and cannot be compared with cloud servers, resulting in reduced computing efficiency.

[0015] According to some embodiments of the present invention, the method further includes: if the network status changes from abnormal to normal, the anti-misoperation industrial control host sends the anti-misoperation list and the status of the electrical terminal to the integrated server; and switches the subject exercising the management authority from the anti-misoperation industrial control host to the edge agent device.

Attached Figure Description

They are used together with the embodiments of the present invention to explain the technical solutions of the present invention, and do not constitute a limitation on the technical solutions of the present invention.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] It should be understood that in the description of the embodiments of the present invention, "multiple" (or "amounts") means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first," "second," etc., are used in the description, they are only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0023] like Figure 1 , Figure 2 As shown, this embodiment of the invention provides an electrical error prevention proxy method, applied to an electrical error prevention proxy system in a smart power plant. The system includes an error prevention industrial control host, an edge proxy device, an integrated server, and an error prevention electrical terminal; the method includes: Step S100: Detect network status; If the network status changes from normal to abnormal, then step S400 is executed, switching the entity exercising management authority from the edge agent device to the anti-misoperation industrial control host; step S500, the anti-misoperation industrial control host detects the status of the anti-misoperation electrical terminal and issues an anti-misoperation command; wherein, the management authority is the authority to manage the anti-misoperation operation of the anti-misoperation electrical terminal; If the network status is normal, then proceed to step S200, where the edge agent device exercises management authority, detects the status of the anti-misoperation electrical terminal and issues an anti-misoperation command; step S300, where the edge agent device sends the status of the anti-misoperation electrical terminal to the anti-misoperation industrial control host.

[0024] For the management of anti-misoperation electrical terminals, the edge agent device is used to handle anti-misoperation under normal network conditions, reducing the latency of centralized processing by the integrated server. In addition, when managing the anti-misoperation electrical terminals, the edge agent device also sends the status of the anti-misoperation electrical terminals to the anti-misoperation industrial control host, enabling the anti-misoperation industrial control host to perform seamless anti-misoperation when the network is abnormal. When the network status is delayed, the anti-misoperation industrial control host takes over the management authority of the anti-misoperation electrical terminals, avoiding the security risks caused by the delay of anti-misoperation commands due to the edge agent device connecting to the network.

[0025] In one embodiment, the method of this embodiment is only applied to the third safety zone of a smart power plant. The third safety zone belongs to the production management zone and provides support for the production management of the power plant.

[0026] It should be noted that Security Zone 1 is a control zone with the highest security level, requiring real-time control, and all operations exchange information with the power grid dispatch in real time; Security Zone 2 is a non-control zone, mainly responsible for uploading information when the dispatch issues a call command.

[0027] In one embodiment, in steps S200 and S500, detecting the status of the anti-misoperation electrical terminal and issuing anti-misoperation instructions includes: Obtain operation requests from anti-misoperation electrical terminal equipment; Collect the status signals and electrical parameters of the corresponding anti-misoperation electrical terminal equipment according to the operation request; The system determines whether the operation request is a mistake based on the status signals and electrical parameters of the anti-misoperation electrical terminal equipment. If it is, a prompt indicating a mistake is issued; otherwise, an instruction to allow the operation request is sent, and the corresponding operation is executed.

[0028] In one embodiment, the anti-misoperation electrical terminal is a high-voltage switchgear, which includes: a circuit breaker for controlling the switching of circuits in the smart power plant; an isolating switch for isolating circuits in the smart power plant; a grounding switch for grounding circuits in the smart power plant; and voltage transformers and current transformers for detecting the voltage and current of circuits in the smart power plant, respectively. The status signals of the anti-misoperation electrical terminal equipment include: the circuit breaker's open / closed status, and the position signals of the isolating switch or grounding switch; the electrical parameters include: the voltage detected by the voltage transformer and the current detected by the current transformer.

[0029] It should be noted that high-voltage switchgear refers to electrical products used in power systems for power generation, transmission, distribution, power conversion and consumption, which play the roles of switching, control or protection, with voltage levels ranging from 3.6kV to 550kV.

[0030] In one embodiment, determining whether an operation request is a erroneous operation based on the status signal and electrical parameters of the anti-maloperation electrical terminal equipment includes: Determine whether the status of the subject corresponding to the operation request matches the operation request. If so, the operation request has been executed. If not, determine whether the subject corresponding to the operation request is energized based on the voltage detected by the voltage transformer and the current detected by the current transformer; if yes, determine that the operation request is an erroneous operation. If not, determine whether the verification operation request is compliant; if yes, determine that the operation request is not a mistake; if no, determine that the operation request is a mistake.

[0031] In one embodiment, the operation request is "open isolation switch". Determining whether the status of the subject corresponding to the operation request meets the operation request specifically means determining whether the isolation switch is already in the open state.

[0032] In one embodiment, the operation request is "open the switch cabinet door", and determining whether the state of the subject corresponding to the operation request meets the operation request specifically means determining whether the switch cabinet door has been opened.

[0033] In one embodiment, determining whether the subject corresponding to the operation request is energized based on the voltage detected by the voltage transformer and the current detected by the current transformer specifically includes: If the voltage detected by the voltage transformer is greater than the preset voltage threshold, it is determined that the main body corresponding to the operation request is energized, and an instruction to prohibit operation of the isolating switch or grounding switch is sent. If the current detected by the current transformer is greater than the preset current threshold, it is determined that the main body corresponding to the operation request is energized, and a command to prohibit the tripping operation is sent to prevent the disconnector from tripping under load.

[0034] In one embodiment, determining whether a verification operation request is compliant includes: Obtain the preconditions for the operation request based on the operation request; Check each operation request sequentially to see if the preconditions are met; if not, determine the permission level of the initiator of the operation request; if the permission level is high, determine that the operation request is compliant; if not, determine that the operation request is non-compliant. If so, then the operation request is deemed compliant.

[0035] It is easy to understand that permission levels include low, medium, and high; when the permission level of the person initiating the operation request is high enough, the prerequisites that need to be met can be ignored.

[0036] In one embodiment, determining whether the preconditions for the operation request are met sequentially includes: Retrieve the rules for the operation request from the preset dynamic rule base; Based on the rules for executing the operation request, the preconditions for the operation request are obtained in sequence; Determine whether the preconditions for each operation request are met.

[0037] It integrates multi-source data such as voltage, current, and disconnector switch status to achieve automatic cross-system verification.

[0038] In one embodiment, the operation request is "switching". The rule for retrieving and executing this operation request is "circuit breaker → load-side isolating switch → power-side isolating switch". The preconditions for the operation request are "circuit breaker, load-side isolating switch, power-side isolating switch". The system sequentially checks whether the circuit breaker is in the open state, whether the load-side isolating switch is in the open state, and whether the power-side isolating switch is in the open state. If all are true, the preconditions for the operation request are met. It is easy to understand that the high-voltage switchgear includes load-side isolating switches and power-side isolating switches.

[0039] In one embodiment, the method further includes: after the anti-misoperation electrical terminal executes the operation corresponding to the operation request, it sends a completion instruction to the anti-misoperation industrial control host. Upon receiving the completion instruction from the anti-misoperation electrical terminal, the anti-misoperation industrial control host adds the sender of the operation request, the operation request, the operation corresponding to the operation request, and the timestamp corresponding to the operation as an anti-misoperation operation to the anti-misoperation operation list. The anti-misoperation operations are stored so that when the network is restored, the anti-misoperation operation list is sent to the integrated server for recording, allowing staff to manually verify them through the integrated server.

[0040] In one embodiment, the method further includes: if the network status changes from abnormal to normal, the anti-misoperation industrial control host sends the anti-misoperation list and the status of the electrical terminal to the integrated server; and switches the subject exercising management authority from the anti-misoperation industrial control host to the edge agent device.

[0041] It's easy to understand that when the network is normal, the management authority remains with the edge agent device. The edge agent device has better performance and computing power than the anti-misoperation industrial control host, and it connects to the anti-misoperation electrical terminal via the network. When an anomaly occurs, the management authority switches to the anti-misoperation industrial control host, which is wired to the anti-misoperation electrical terminal and is unaffected by network fluctuations. Furthermore, when the edge agent device manages the anti-misoperation electrical terminal, it continuously sends the terminal's status to the anti-misoperation industrial control host, which, lacking management authority, does not issue anti-misoperation commands.

[0042] like Figure 1 As shown, this embodiment of the invention also provides an electrical error prevention agent system, including: an error prevention industrial control host, an edge agent device, an integrated server, an error prevention electrical terminal, and an error prevention agent device; The error prevention agent device is connected to the error prevention industrial control host and the edge agent device respectively, and is used to execute the above-described method; The edge agent device is also connected to the integrated server and the anti-misoperation electrical terminal respectively. If the network status is normal, it is used to exercise management authority, detect the status of the anti-misoperation electrical terminal and issue anti-misoperation instructions, and send the status of the anti-misoperation electrical terminal to the anti-misoperation industrial control host. The anti-misoperation industrial control host is also connected to the integrated server and the anti-misoperation electrical terminal. If the network status is abnormal, it is used to exercise management authority, detect the status of the anti-misoperation electrical terminal, and issue anti-misoperation instructions.

[0043] like Figure 3 As shown, in one embodiment, the electrical error prevention agent system is independent of the existing devices within the edge computing area of ​​the smart power plant, encompassing both hardware and software. The hardware specifically includes: Hardware for preventing accidental operation (i.e.) Figure 3 The anti-misoperation business application layer constitutes the highest level of the anti-misoperation agent device, including the anti-misoperation business application 5G communication component and the anti-misoperation industrial control host module, which provides interfaces for human-computer interaction of various business data and management data; Communication interface hardware (i.e.) Figure 3 The communication interface layer integrates 5G wireless interfaces and RS-232 / 485 wired interfaces.
