[0033] 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.

[0034] 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.

[0035] According to an embodiment of the present application, a system for preventing misoperation of a control element in a power grid is provided. Figure 1 is a schematic diagram of an anti-error protection system for control elements in a power grid according to the present application, such as Figure 1 As shown, the anti-error protection system 102 of the control element in the power grid includes: a plurality of anti-error interlocking devices 104 and a centralized control device 106 .

[0036] Multiple anti-error interlocking devices 104 are set one-to-one corresponding to multiple control elements that need to be interlocked in the power grid. The anti-error interlocking devices are used to collect current status information of the corresponding control elements, transmit the current status information to the centralized control device, and perform anti-error interlocking protection on the control elements based on the target control instructions transmitted from the centralized control device.

[0037] The above-mentioned interlocking control may refer to a certain association or dependency between the control elements in the power grid, and interlocking protection is required between the control elements to ensure the safety and stability of the power grid operation. For example, assuming that there are multiple circuit breakers and grounding switches in a substation, when a circuit needs to be maintained or troubleshooted, it is necessary to ensure that the grounding switch is opened while the circuit is disconnected to ensure the safety of the operator. At this time, the circuit breaker and the grounding switch need to be interlocked, that is, the circuit breaker can only be operated under specific conditions to prevent accidents caused by misoperation.

[0038] The above-mentioned control elements may refer to various switches, circuit breakers, isolating switches, grounding switches and other electrical elements used to control the operating status of the power system and circuit connections that need to be interlocked in the power grid. The control elements can open, close, connect and disconnect circuits in the power system as needed to ensure the safe and stable operation of the power grid. When the control element is a knife switch device, the knife switch device can control the on and off of the circuit according to the operating conditions and needs of the power grid to prevent short circuits or overloads and other faults. In the anti-error protection system, an anti-error interlocking device can be set to correspond to the knife switch device one by one. By collecting the current status information of the knife switch device and transmitting it to the centralized control device, remote monitoring and control of the knife switch device can be realized. When the centralized control device issues a target control instruction, the anti-error interlocking device will perform a protective operation on the knife switch device to ensure that it operates in the correct state and avoids power grid failures caused by misoperation. The specific type of control element can be determined according to actual needs and is not limited here.

[0039] The above-mentioned anti-error interlocking device may refer to a device used to implement interlocking control in the anti-error protection system of the control element in the power grid. It can collect the current state information of the control element and transmit it to the centralized control device, so as to perform anti-error interlocking protection on the control element according to the target control instruction sent by the centralized control device; for example, assuming that there are multiple switches and circuit breakers in a power grid that need to be interlocked, the anti-error interlocking device can be set one by one with each switch and circuit breaker. When the centralized control device receives the need to perform an operation on a certain switch or circuit breaker, the anti-error interlocking device will first collect the current state information of the control element, and then transmit it to the centralized control device. The centralized control device will determine whether the operation can be performed based on this information, and send the target control instruction to the anti-error interlocking device. The anti-error interlocking device then performs anti-error interlocking protection according to these instructions to ensure that no false action or wrong operation occurs during the operation.

[0040] The above-mentioned current status information may refer to the real-time status of the control element, which may include but is not limited to the switch status, current, voltage and other related information of the control element. For example, when the control element is a circuit breaker, the circuit breaker has two states: open and closed. The anti-error interlocking device can monitor the status of the circuit breaker in real time. If the circuit breaker is in the open or closed state, the anti-error interlocking device can collect this status information and transmit it to the centralized control device.

[0041] The above-mentioned target control instruction may refer to the target status information issued by the centralized control device, which is used to guide the anti-error interlocking device to perform anti-error interlocking protection on the control elements. When the centralized control device needs to operate certain control elements in the power grid, it can generate corresponding target control instructions. The anti-error interlocking device can determine whether to perform the operation based on the target control instruction. If there is a potential danger or the operation does not comply with safety regulations, the anti-error interlocking device will refuse to perform the operation, thereby avoiding accidents caused by incorrect operation.

[0042] In an optional embodiment, in the anti-error protection system of the control elements in the power grid, multiple anti-error interlocking devices can be set in one-to-one correspondence with multiple control elements that need to be interlocked in the power grid, which can ensure that each control element has a corresponding anti-error interlocking device for monitoring and protection; the anti-error interlocking device collects the current status information of the corresponding control element, such as switch status, current, voltage and other information, and transmits this information to the centralized control device. The centralized control device can determine whether anti-error interlocking protection is needed based on the received current status information and preset anti-error rules, and send target control instructions to the corresponding anti-error interlocking device. The device can lock or unlock the control element according to this instruction to ensure that the control element cannot be operated under specific conditions to prevent accidents caused by misoperation. Through the above settings, the anti-misoperation interlocking device can timely monitor the status of the control element and take protective measures when necessary, effectively reducing the risks brought by misoperation and ensuring the safe and stable operation of power grid equipment and systems. In the anti-misoperation protection system, the present application sets up multiple anti-misoperation interlocking devices corresponding to multiple control elements that need to be interlocked control, which can realize the monitoring and protection of the relationship between these control elements and avoid the occurrence of power grid accidents due to misoperation or other reasons.

[0043] The centralized control device 106 is used to perform interlocking judgment on the received current status information, generate a target control instruction, and transmit the target control instruction to the corresponding anti-mistake interlocking device.

[0044] The above-mentioned centralized control device may refer to a processor or controller, which is used to monitor, control and coordinate each component in the entire anti-error protection system. It can receive the current status information corresponding to each component, perform logical judgment and interlocking control, generate target control instructions, and transmit the instructions to the corresponding anti-error interlocking device.

[0045] For example, in a substation's anti-error protection system, the centralized control device may be a console or a computer system, which may obtain status information of various components of the substation, such as circuit breakers, relays, transformers, etc., such as current, voltage, temperature and other data, through various anti-error interlocking devices. By analyzing these data, the centralized control device may determine the current operating status of the system and generate corresponding control instructions according to preset logical rules, such as allowing or prohibiting the closing of a circuit breaker. The centralized control device may be set according to actual needs, which is not limited here.

[0046] In an optional embodiment, in the anti-error protection system of the control elements in the power grid, the centralized control device can receive the current status information collected from each anti-error interlocking device, and then perform interlocking judgment based on the current status information, generate corresponding target control instructions, and finally transmit these instructions to the corresponding anti-error interlocking device. Specifically, the centralized control device can receive the status information from each anti-error interlocking device in real time. This information may include real-time data of parameters such as current, voltage, and temperature. The received data can be processed and analyzed, and interlocking logic or conditional judgment can be performed to generate target control instructions, and the generated target control instructions can be transmitted to the corresponding anti-error interlocking device, so that the anti-error interlocking device performs the corresponding control action. In this way, through the scheduling and management of the centralized control device, it is possible to effectively prevent misoperation and failures from occurring, and improve the safety and reliability of the power grid system.

Through the above-mentioned settings, the anti-error protection system realizes the automated processing of status information collection, interlocking judgment and control instruction generation of control elements in the power grid, effectively improving the automation degree and efficiency of the system, thereby solving the technical problems of low automation degree and efficiency of anti-error protection of control elements in the power grid in related technologies.

[0049] The above-mentioned status acquisition module may refer to a device or system for detecting the current position information of the control element. The status acquisition module may be a photographic device, a radar device or various sensors, etc. For example, the status acquisition module may be a position sensor for detecting the position of the knife switch device, such as the closed or open state. When the switch device is in the closed state, the status acquisition module may collect the information of the closed state; when the switch device is in the open state, the status acquisition module may collect the information of the open state. The status acquisition module may be determined according to actual needs and is not limited here.

By monitoring the position of the control element, the system can understand the state of the control element in real time, so as to take corresponding anti-error measures in time; the anti-error interlocking execution module can perform opening and closing lock operations based on the target control instruction to perform anti-error interlocking protection on the control element, and can accurately operate the control element according to the interlocking logic and rules set by the system to ensure that the interlocking protection function can be correctly executed under specific circumstances to prevent equipment damage or accidents caused by misoperation; the controller module connects the state acquisition module and the anti-error interlocking execution module, plays a role of coordination and control, the controller module can generate current state information according to the current position information transmitted by the state acquisition module, and transmit the target control instruction transmitted by the centralized control device to the anti-error interlocking execution module, which can realize the monitoring and control of the entire anti-error interlocking system to ensure the normal operation and safety of the system. The anti-error interlocking device ensures the safe and stable operation of the power grid system through functions such as state acquisition, execution of interlocking and control management.

[0051] Optionally, a magnetic material is provided on the control element; the state acquisition module includes: a magnetic sensor, used to collect magnetic field changes around the control element to obtain magnetic field change information; a signal processing unit, connected to the magnetic sensor, used to determine the position change of the control element based on the magnetic field change information to obtain current position information.

[0052] In an optional embodiment, in the anti-error protection system of the control element in the power grid, a magnetic material can be provided on the control element, so that the position of the control element can be accurately obtained. Specifically, by providing the magnetic material on the control element, the magnetic field change around the control element can be collected by a magnetic sensor, thereby obtaining the position information of the control element; the state acquisition module can include a magnetic sensor and a signal processing unit, and the magnetic sensor can be used to collect the magnetic field change around the control element and transmit the magnetic field change information to the signal processing unit; the signal processing unit is connected to the magnetic sensor, and can determine the position change of the control element by processing and analyzing the magnetic field change information, and finally obtain the current position information. Through the above design, the system can monitor the position of the control element in real time to ensure that it is operated in the correct position, thereby avoiding safety problems caused by misoperation; at the same time, by using the combination of magnetic material and magnetic sensor, high-precision monitoring of the position of the control element can be achieved. In particular, accurate collection of the current position information of the control element in a dark environment can be achieved, thereby improving the accuracy and stability of the system, thereby effectively ensuring the safe operation of the power grid equipment.

[0053] Optionally, the anti-error interlock execution module includes: a transparent cover plate covering the control element, a magnetic attraction component being provided at one end of the transparent cover plate, wherein the transparent cover plate is used to perform anti-error protection on the control element when it is in a closed state, and allows the user to perform control operations on the control element when it is in an open state; a relay, used to attract or disconnect the magnetic attraction component to control the transparent cover plate to be in a closed state or an open state; and a driving unit, connected to the relay, for controlling the relay to attract or disconnect the magnetic attraction component based on a target control instruction.

[0054] In an optional embodiment, in the anti-error protection system of the control element in the power grid, the anti-error interlock execution module can be used to prevent misoperation in the anti-error protection system of the control element in the power grid, and the anti-error interlock execution module may include a transparent cover, a relay and a drive unit, wherein the transparent cover can cover the control element, and a magnetic suction component is provided at one end of the transparent cover to control the opening and closing state of the transparent cover by magnetic attraction.

When the user needs to unlock the anti-error interlocking device, the system only needs to press the unlocking button to trigger the system to collect the current status information and generate a target control instruction; the indicator light may be a device for displaying the open / closed locking state of the anti-error interlocking device. Based on the generated target control instruction, the indicator light will notify the user of the current open / closed locking state with different light display states. By observing the state of the indicator light, the user can intuitively understand the operation of the anti-error interlocking device, thereby ensuring the correct operation of the device.

Through the cooperation of the above-mentioned devices, the system can achieve a more intelligent and intuitive operation mode, thereby improving the reliability and stability of the device.

[0059] The following is an explanation of an optional application scenario of the anti-error protection system for control elements in the power grid proposed in the present application: In order to ensure the stable and reliable operation of the primary and secondary equipment of the substation, the station power supply system usually adopts a ring network power supply design. The advantage of this design is that when the main power supply circuit fails, it can be switched to the backup power supply through the electrical operation of the staff to maintain continuous power supply. However, during the power supply process, it is strictly forbidden to close the main power supply and the backup power supply to avoid the substation power supply voltage loss. However, since the main power switch and the backup power switch are usually not in the same panel cabinet, and there is a lack of an interlocking mechanism between the main power switch and the backup power switch, this increases the risk of misoperation during operation and accidental contact in daily work. Therefore, it is necessary to use technical means to prevent misoperation and make the station ring network power supply system run in parallel; currently The microcomputer anti-error locking system has been widely used as a technology to prevent electrical misoperation during the switching operation of the substation. However, the system mainly focuses on the prevention of errors in the primary equipment on the high-voltage side, and the means for preventing errors in the operation of secondary equipment such as the station ring network power switch are still insufficient. If the station ring network power is closed, it may cause the station power supply of the entire substation to lose voltage, thereby causing a more serious power grid accident; the present application proposes an anti-error device and method for interlocking the operation of the ring network power system switch, which can be an anti-error protection system for the control elements in the above-mentioned power grid. This system has more effective operation interlocking and anti-error functions to improve the overall safety and reliability of the substation. This system can fill the gap in the existing anti-error technology in the station ring network power management and ensure the safety and stability of the substation under various operating conditions.

[0060] At present, the measures for preventing loop power supply in substations mainly rely on hanging identification plates on power switches or mechanical locks with single functions to prevent operators from operating them at will. However, although this locking method has a certain locking capability, it lacks an interlocking mechanism with other power switches, making it difficult to effectively control the power transmission operation process. This protective measure has obvious safety hazards. Due to the lack of mandatory interlocking functions, these existing measures fail to effectively prevent potential risks in the loop power supply process, which may lead to system failures or safety accidents.

In terms of implementation standards, it can be implemented in accordance with the current standards and can be determined according to actual needs, which is not limited here.

[0062] The physical network smart lock can be the above-mentioned anti-misinterlocking device.

[0077] The present application provides an anti-error device and method for interlocking the switch operation of a ring network power supply system. Aiming at the potential safety hazard of mistaken ring closing operation when operating the ring network power switch, the system effectively solves the safety risk of mistaken ring closing operation of the station-use ring network power supply system of the substation through technical means. The existing prompt locking method of the station-use ring network power switch is relatively insufficient in applicability, flexibility and anti-error measures for operators. In view of this, the ring network power switch operation interlocking system provided by the present application is equipped with a physical network smart lock with equipment forced locking, equipment status perception, and wireless communication; it is equipped with an interlocking anti-error system that can centrally monitor the equipment status, define the equipment operation interlocking logic, and make operation judgments based on the real-time location of the equipment. The proposed ring network power system switch operation interlocking anti-error device and method, the system configuration can include the ring network power system switch interlocking anti-error software, which can be the above-mentioned centralized control device, and the Internet of Things smart lock; on the basis of traditional anti-error, this system can adopt C / S architecture, the server-side operation interlocking anti-error system software, each station uses the ring network power switch to install the Internet of Things smart lock, and the Internet of Things smart lock acts as a client to interact with the server in real-time business data through the Internet of Things communication protocol. Among them, the ring network power system switch operation interlocking anti-error software runs on the ring network power management host, is responsible for communicating with each Internet of Things smart lock through the Internet of Things wireless communication protocol, obtains the real-time status of the power switch, and performs anti-error judgment on the request unlocking behavior of the Internet of Things smart lock according to the real-time status of the interlocked power switch; the Internet of Things smart lock is installed on each power switch, and the switch operation is forcibly locked, and the unlocking operation can only be performed after the interlocking anti-error judgment is passed.

[0078] The system proposed in this application is configured with a system software that can perform interlocking logic and error prevention of station ring network power switch operation, and an intelligent lock for Internet of Things communication, so as to logically associate the station ring network power switch state with the state of the relevant equipment in the interlocking rule, and use the error prevention rule of first performing interlocking judgment and then unlocking to avoid the operational risk of station ring network power supply closing to a great extent. The system realizes the prevention of the operational risk of station ring network power switch closing by configuring the operation interlocking and error prevention system software and the Internet of Things intelligent lock. The Internet of Things intelligent lock is mainly used to force the power switch to be locked. Only after the logical judgment of the operation interlocking and error prevention system is passed, can the Internet of Things intelligent lock be unlocked and the device can be operated. The intelligent lock can have the functions of status display, status upload and status collection. In the operation interlocking and error prevention system, the Internet of Things intelligent lock can be used to force the ring network power switch to be locked, and to collect the status signal, and can upload the status information of the ring network power switch to the operation interlocking and error prevention system.

[0079] The operation interlocking and anti-error system software proposed in the present application can obtain the status of the power switch device in real time by communicating with the Internet of Things smart lock, realize real-time monitoring of the power switch status, and make anti-error judgments based on the real-time status of the power switch and the interlocking and anti-error rules.

[0080] The IoT smart lock can be composed of five modules: power module, status acquisition module, magnetic sensing element, decision control module, unlocking operation and indication module. The magnetic sensor installed on the power switch is combined with the magnet to detect the state of the switch using the change of the magnetic field. After the magnetic sensor detects the change of the magnetic field, it converts it into an electrical signal. The data processing unit determines the actual state of the switch based on these signals and feeds the results back to the status acquisition module. This technology can monitor the power switch state with high precision and contactless, has strong adaptability to the environment, and improves the monitoring accuracy and reliability of the power switch equipment.

Specifically, a corresponding interlocking strategy can be formulated according to the actual situation and needs of the power grid system. The interlocking strategy can include logical judgment, conditional restrictions, priority settings, etc. to ensure that the operation of the control element will not cause misoperation or accidents; the control element can be interlocked according to the current state information and the interlocking strategy.
