Existing master-substations have the defects of requiring power outage during one-key sequential control, being unable to perform interoperability debugging, and being unable to perform automatic calibration during one-key sequential control. The present invention first obtains a list of interval operation tickets to be verified, and sequentially summons the operation tickets that need to be summoned, including review, preview, and execution, and then summons the next unreviewed operation ticket of the current interval; and then repeats the above steps until all the operation tickets of the intervals have been verified. The present invention is mainly used to realize the automatic calibration operation of the master-substation one-key sequential control without power outage without expanding the functions of the master-substation.

Description

Technical Field

[0001] The invention relates to the field of power system automation, and in particular to a master-substation one-button sequential control non-power-off automatic calibration method and a calibration system thereof. Background Art

[0002] Substation one-button sequential control operation is a new mode of switching operation, which can effectively reduce the switching operation and power outage time, reduce economic losses and the probability of switching error operation. Substation one-button sequential control operation mode is divided into two types: substation local operation and master station remote operation. The substation local operation mode refers to the sequential control operation completed through the sequential control host interface deployed in the substation, and the master station remote operation mode refers to the sequential control operation completed by issuing instructions to the substation sequential control host through the master station system's sequential control function interface.

[0003] At present, the construction of the new generation of centralized control stations and the construction of one-button sequential control of substations are being promoted simultaneously. However, due to differences in construction scale, implementation cycle, and construction personnel, it is impossible to guarantee that both can meet the conditions for interoperability debugging before their respective construction and commissioning. Usually, before the construction of the one-button sequential control of the substation is completed, the debugging personnel only verify the local operation mode of the substation. Since the new generation of centralized control station system corresponding to the substation has not been completed, the verification of the remote operation mode of the master station cannot be carried out. After the construction of the new generation of centralized control station system is completed, the substations within its jurisdiction are all in energized operation, and it is impossible to carry out the interoperability debugging of the one-button sequential control function of the master and substations, and it is even more impossible to actually control the primary equipment such as switches and knife switches in the energized operation of the substation through the remote operation mode of the master station of the one-button sequential control.

[0004] Patent CN112698584B discloses a substation one-button sequential control simulation test method, device, equipment and medium, which mainly provides a method for verifying the local operation mode of the one-button sequential control substation by simulating the actual operating environment of the substation in a simulation test environment, but cannot solve the problem of interoperability debugging of the one-button sequential control function of the master and substations.

[0005] Patent CN117539220A discloses a one-button sequential control test system and method based on virtualization simulation. It mainly provides a method for simulating the plant-side interval layer equipment to interact with the substation one-button sequential control system, thereby verifying the local operation mode of the one-button sequential control substation. It also cannot solve the problem of interoperability debugging of the one-button sequential control function of the master and substation.

[0006] Patent CN116775224B discloses a one-button sequential control test system and test method, which mainly provides a method for verifying the local operation mode of a one-button sequential control substation by means of a virtual machine master platform and an equipment virtual machine. However, it still cannot solve the problem of interoperability debugging of the one-button sequential control function of the master and substations.

[0007] Patent CN117277552A discloses a smart grid one-button sequential control verification system and method, which mainly provides a method for verifying the remote operation mode of the one-button sequential control master station by using a centralized control master station, a data communication gateway, a monitoring host, an anti-error host and a one-button sequential control verification device. However, this method puts forward corresponding requirements for the extension protocol of the centralized control master station system, and requires that the centralized control master station system and the one-button sequential control verification device have the conditions for communication and interaction during debugging, which is difficult to achieve in practical applications. The main reason is that the centralized control master station system, as a standardized system-level product, cannot expand its functions at will. If there is any functional expansion, it must be tested by a professional testing agency. In addition, the substation debugging site does not have a physical communication channel between the centralized control master station system and the one-button sequential control verification device, so this method does not have broad promotion significance.

[0008] Patent CN116979682A discloses a method and device for automatic acceptance of substation one-key sequential control synchronization based on actual remote control. It mainly provides a method for verifying the data communication gateway, sequential control host, and measurement and control device in the one-key sequential control system of the substation by simulating the dispatching master station and the interval layer equipment using the one-key sequential control automatic acceptance device. Since this method uses a simulated master station to communicate with the one-key sequential control system to interact between the master and substation, and the simulated master station cannot completely replace the real centralized control master station, that is, the functional problems and configuration errors in the centralized control master station system cannot be reflected in the simulated master station, so this method is only suitable for verifying the correctness of the functions and configurations in the one-key sequential control system of the substation, and cannot verify the correctness of the one-key sequential control functions and configurations in the centralized control master station system. It has certain limitations and is significantly different from the method disclosed in the present invention.

[0009] In summary, there is a need for a one-key sequential control method and a non-power-off automatic calibration system for the master substation, which can realize one-key sequential control operation on the master substation without expanding functions and without power outage, so that the master substation can interoperate, debug and automatically calibrate. Summary of the invention

[0027] S27: The message monitoring and parsing software monitors and parses the access response message, determines and marks whether the current operation ticket has been accessed.

[0028] Further: in S23, the equipment initial state information refers to the remote signaling state information of the substation primary equipment corresponding to the operation ticket, and the remote signaling state information includes the opening / closing position of the primary equipment.

[0054] Example 1

[0055] Combination Figure 1-Figure 6 This embodiment describes a method for automatic calibration of a master-substation with one-key sequential control without power outage, including the following steps:

[0056] S1: Get the list of interval operation tickets to be checked;

[0057] like Figure 1 and Figure 2 As shown, in S1, the interval operation ticket list is formed by performing one-key sequential control verification of the master substation between the centralized control system and the substation according to the interval.

[0058] In S1, firstly, the verification preparation is carried out, that is, the debugging environment is set up, such as Figure 3 The specific steps are as follows:

[0059] S11: Disconnect the standby gateway and the sequential control host in the substation master and standby gateway from the station control layer network and connect them to an independent debugging network;

[0060] Specifically, it includes: building a debugging network isolated from the operating network environment, disconnecting the standby gateway and the sequential control host in the main and standby gateways from the operating network, and connecting them to an independent debugging network. The main gateway continues to operate in the operating network without being affected, and the protection device and the measurement and control device continue to operate normally with power on; thereby ensuring that the communication interaction behavior in the debugging network will not affect the station control layer network in the operating area and the main substation communication interaction between the main gateway and the dispatching master station system;

[0061] like Figure 4 As shown in the pre-debugging operation network architecture diagram, the dispatching master station system communicates with the main gateway machine and the backup gateway machine at the same time. The station sequential control host, protection device and measurement and control device communicate with the two gateway machines through the station control layer network. The newly added centralized control system does not establish master-substation communication interaction with the gateway machine.

[0062] like Figure 5 As shown in the debugging network architecture diagram, the debugging network is isolated from the station control layer network, the dispatching master station system maintains communication interaction with the main gateway machine, and the protection device and the measurement and control device maintain communication interaction with the main gateway machine through the station control layer network; the standby gateway machine and the sequential control host are connected to the debugging network, and the standby gateway machine communicates with the centralized control system through the newly added mirror switch. The message monitoring and parsing software is connected to the mirror network port of the mirror switch, and the protection and measurement and control devices virtualized by the interval layer device simulation software communicate with the standby gateway machine and the sequential control host within the station through the debugging network, and the message monitoring and parsing software communicates internally with the interval layer device simulation software.

[0063] like Figure 6 As shown in the post-debugging operation network architecture diagram, the centralized control system communicates with the main gateway machine and the backup gateway machine at the same time after the main substation one-touch sequential control and automatic verification without power outage. The dispatching master station system communicates with the main gateway machine and the backup gateway machine at the same time. The sequential control host, protection device and measurement and control device in the station communicate with the two gateway machines through the station control layer network.

[0064] S12: Setting the communication parameters and communication point table of the standby gateway and the centralized control system; Setting the communication parameters of the standby gateway and the centralized control system, including the communication protocol type, IP address, subnet mask, port number, etc., and configuring the communication point table forwarded by the standby gateway to the centralized control system, including data point information such as telemetry, telecommunication, and remote control;

[0065] S13: Connect the standby gateway machine to the centralized control system through a mirror switch, and mirror the interactive network port of the standby gateway machine to ensure that the communication interaction messages between the standby gateway machine and the centralized control system are mirrored to the designated switch network port;

[0066] Specifically, it includes: adding a mirror switch between the backup gateway machine and the centralized control system, setting its network port mirroring parameters, and ensuring that the communication messages interacting between the backup gateway machine and the centralized control system can be mirrored to the designated network port.

[0067] S14: The standby gateway machine establishes a master-substation communication interaction with the centralized control system to ensure that all communication interaction messages can be monitored and analyzed by the message monitoring and analysis software from the mirror network port of the mirror switch;

[0068] S15: Simulate a virtual protection device and a virtual measurement and control device in the debugging network, import the device files into the virtual protection device and the virtual measurement and control device respectively, the virtual protection device and the virtual measurement and control device extract the telemetry, telesignaling and / or remote control information of each device by parsing the device files and complete the initialization; import the information point table or ICD (IED Capability Description) file of the protection and measurement and control device into the bay layer device simulation software and start the virtual protection device and the virtual measurement and control device;

[0069] In S15, the device file includes an information point table file or an ICD file.

[0070] Specifically include:

[0071] Use the bay layer device simulation software to simulate virtual protection devices and virtual measurement and control devices in the debugging network that are consistent with the parameters and communication behaviors of the protection devices and measurement and control devices in the running network. For the protection and measurement and control devices that use the conventional substation 103 communication protocol, import the 103 information point table file corresponding to each device; for the protection and measurement and control devices that use the smart substation MMS communication protocol, import the ICD file of each device and complete the initialization;

[0072] S16: importing the model file related to the one-key sequence control in the sequence control host into the message monitoring and parsing software and the bay layer device simulation software for parsing, and establishing the same one-key sequence control parameters in the message monitoring and parsing software and the bay layer device simulation software respectively;

[0073] Specifically, it includes: importing the model files such as the bay list, bay equipment status list, bay operation ticket list, and operation ticket in the sequence control host into the message monitoring and parsing software and the bay layer device simulation software, so that it can parse and extract the corresponding relationship between the bay equipment status and the switch and knife switch remote signal status, the corresponding relationship between each step in the operation ticket and the switch and knife switch remote control point, and the corresponding relationship between each remote control point and the remote signal, etc., and establishing the same one-key sequence control parameters in the message monitoring and parsing software and the bay layer device simulation software for use in the automatic verification process;

[0074] S17: The message monitoring and parsing software and the bay layer device simulation software perform real-time internal interaction during the automatic verification process, and set the configuration parameters of the internal interaction between the two, including IP address, subnet mask, port number, etc., wherein the message monitoring and parsing software serves as the client, and the bay layer device simulation software serves as the server, and sets the working modes of the two; the working modes include only operation ticket review and verification, operation ticket review and rehearsal review, and full process review; wherein the operation ticket review and rehearsal review mode refers to directly reviewing the next operation ticket without rehearsal and subsequent process verification after the operation ticket review is completed, the operation ticket review and rehearsal review mode refers to directly reviewing the next operation ticket without execution verification after the operation ticket review and rehearsal, and the full process verification mode refers to verifying the operation ticket review, rehearsal and execution;

[0075] S18: Check whether the communication interaction between each module is normal, ensure that the communication interaction between each system, device and software is normal, the master substation agrees whether to perform operation ticket preview and execution verification, and switch the working mode of the message monitoring and parsing software and the interval layer device simulation software; check to ensure that the master substation communication interaction between the centralized control system and the backup gateway machine is normal, including the monitoring function of the message monitoring and parsing software through the mirror network port of the mirror switch, the protection and measurement and control devices virtualized by the interval layer device simulation software and the backup gateway machine and the sequential control host are normal, the internal communication interaction between the message monitoring and parsing software and the interval layer device simulation software is normal, the master substation agrees whether to perform operation ticket preview and whether to perform the verification process of operation ticket execution, and switches the message monitoring and parsing software and the interval layer device simulation software to the corresponding working mode.

[0076] S2: reviewing the operation tickets to be checked in the interval operation ticket list;

[0077] like Figure 2 The specific flow chart of previewing, executing, calling and checking the operation ticket shown in FIG. 1 shows that in S2, calling the operation ticket specifically includes the following steps:

[0078] S21: The centralized control system selects an unchecked interval and issues a call command to the current interval operation ticket list to call the interval operation ticket list; the one-key sequential control check between the master and substation between the centralized control system and the substation is performed according to the interval, and the centralized control system selects the first unchecked interval from the interval list and issues a call command for the interval operation ticket list;

[0079] S22: After the sequence control host receives and analyzes the call command, it generates a call response message and sends it to the centralized control system; the call interval operation ticket list command is sent to the sequence control host via the mirror switch and the standby gateway, and the sequence control host responds and uploads the response result;

[0080] The command for calling the interval operation ticket list issued by the centralized control system is sent to the sequential control host via the mirror switch and the backup gateway. After the sequential control host receives and parses the command, it generates an interval operation ticket list response message, which is sent to the centralized control system via the backup gateway and the mirror switch.

[0081] S23: the message monitoring and parsing software monitors and parses the call response message, stores the current operation ticket list, and obtains the device initial state information corresponding to the operation ticket; the message monitoring and parsing software monitors and parses the operation ticket list, and transmits the device initial state information corresponding to the first unread operation ticket in the list to the bay layer device simulation software;

[0082] The message monitoring and parsing software monitors and parses the operation ticket list response message sent to the centralized control system through the mirror network port of the mirror switch, and stores the operation ticket list in the software memory. At the same time, the flag of whether each operation ticket in the list has been read is set as unread. Then, the first unread operation ticket is selected, and the corresponding device initial state information is found from the one-key sequential control parameters of the software, and the information is passed to the interval layer device simulation software through internal communication interaction.

[0083] Specifically, the message monitoring and parsing software monitors the communication interaction messages between the centralized control system and the standby gateway in real time. When the response frame of the call operation ticket list sent by the standby gateway is identified, the operation ticket content contained in the list is extracted, and the first unread operation ticket in the list is located. The initial state information of the equipment corresponding to the operation ticket is queried in combination with the one-key sequential control parameters established by itself, and the initial state information of the equipment is passed to the interval layer device simulation software;

[0084] In S23, the equipment initial state information refers to the remote signaling state information of the substation switches, circuit breakers and other primary equipment corresponding to the operation ticket, and the remote signaling state information includes the open / closed position of the switches, circuit breakers and other primary equipment.

[0085] S24: the bay layer device simulation software receives and analyzes the initial state information of the device, and sets the corresponding telesignaling state of the virtual protection and measurement and control device to meet the conditions for subsequent reading of the operation ticket;

[0086] Specifically, the bay layer device simulation software receives and analyzes the initial state information of the equipment transmitted by the message monitoring and analysis software, finds the corresponding relationship between the initial state of the equipment and the remote signal state of the switch and the knife switch from the one-key sequential control parameters of the software, extracts the remote signal state that each switch and the knife switch should reach, and sets the corresponding remote signal state of its own virtual protection and measurement and control device through the internal interface of the software to meet the conditions for the subsequent reading of the operation ticket, otherwise the operation of reading the operation ticket of the centralized control master station will fail due to the failure to meet the initial state of the equipment;

[0087] The bay layer device simulation software receives the remote control command and sets the remote signal state corresponding to the remote control to meet the execution conditions of the subsequent operation steps, specifically including:

[0088] After receiving the remote control commands of switches and knife switches issued by the sequence control host according to the order of the operation ticket steps, the bay layer device simulation software queries the remote signal point corresponding to the remote control command in its own virtual protection and measurement and control device, and sets the remote signal state to be achieved according to the remote control value to meet the execution conditions of the next step of the operation ticket executed by the sequence control host;

[0089] S25: the centralized control system issues a review command to the current operation ticket whose telesignaling state corresponding to the initial state information of the equipment is successfully set; the centralized control system issues a command for the first unreviewed operation ticket in the call list; the centralized control system selects the first unreviewed operation ticket in the interval list and issues a review command;

[0090] S26: After the sequential control host receives and parses the access instruction, it generates a access response message and sends it to the centralized control system; the access operation ticket command is transmitted to the sequential control host via the mirror switch and the backup gateway, and the sequential control host responds and uploads the response result; after the sequential control host receives and parses the command, it generates a access operation ticket response message and sends it to the centralized control system via the backup gateway and the mirror switch;

[0091] S27: The message monitoring and parsing software monitors and parses the access response message, determines and marks whether the current operation ticket has been accessed. If the preview verification of the operation ticket is carried out, the master-substation one-key sequential control operation ticket preview verification step is entered, otherwise the message monitoring and parsing software transmits the equipment initial state information corresponding to the next un-accessed operation ticket in the interval to the interval layer device simulation software;

[0092] The message monitoring and parsing software monitors and parses the total result of successful execution, and determines that the execution of the operation ticket is completed, specifically including:

[0093] The message monitoring and parsing software monitors the communication interaction messages between the centralized control system and the standby gateway machine in real time. When the total result of the successful execution of the operation ticket sent by the standby gateway machine is identified, it is determined that all steps in the current operation ticket have been completed.

[0094] Specifically: the message monitoring and parsing software monitors and parses the response message of the end of the operation ticket review sent to the centralized control system via the mirror network port of the mirror switch, determines that the operation ticket review is completed, and sets the review flag corresponding to the operation ticket in the software memory to have been reviewed; if the working mode of the software is the operation ticket review and verification mode only, the message monitoring and parsing software passes the equipment initial state information corresponding to the next unreviewed operation ticket in the interval to the interval layer device simulation software, and waits for the centralized control system to review the next operation ticket. If the working mode of the software is the operation ticket review and rehearsal verification mode or the full process verification mode, wait for the centralized control system to perform the operation ticket rehearsal verification step;

[0095] After reviewing the operation ticket, the centralized control system sends the rehearsal command of the operation ticket to the sequential control host via the mirror switch and the backup gateway. After the sequential control host receives and parses the command, it starts the rehearsal operation and uploads the rehearsal result to the centralized control system via the backup gateway and the mirror switch. After all the steps of the operation ticket are rehearsed, the sequential control host sends a rehearsal end response.

[0096] S3: If the current operation ticket does not need to be rehearsed, jump to S5; if a rehearsal is required, the master station sends a rehearsal instruction, and the substation rehearses the current operation ticket and uploads the rehearsal instruction; the centralized control system sends the rehearsal command for the operation ticket, the sequence control host responds and starts the rehearsal operation and uploads the rehearsal result; the message monitoring and parsing software monitors and parses the rehearsal end response, and determines that the rehearsal of the operation ticket is over; if the execution of the operation ticket is to be verified, enter the master-substation one-key sequence control operation ticket execution verification step, otherwise the message monitoring and parsing software passes the equipment initial state information corresponding to the next unreviewed operation ticket in the interval to the interval layer device simulation software;

[0097] The message monitoring and parsing software monitors and parses the rehearsal end response message sent to the centralized control system via the mirror network port of the mirror switch, and determines that the rehearsal of the operation ticket has ended; if the working mode of the software is the operation ticket review and rehearsal verification mode, the message monitoring and parsing software passes the equipment initial state information corresponding to the next unreviewed operation ticket in the interval to the interval layer device simulation software, and waits for the centralized control system to review the next operation ticket. If the working mode of the software is the full-process verification mode, wait for the centralized control system to perform the operation ticket execution verification step;

[0098] S4: If the current operation ticket does not need to be executed, jump to S5; if it needs to be executed, the master station sends an execution instruction, and the slave station executes the current operation ticket and uploads the execution instruction;

[0099] In S3 and S4, whether the current operation ticket is previewed and / or executed is determined according to the preset working mode of the operation ticket and / or the verification instructions of the sequential control master station; the preset working mode includes a review-only verification mode, a preview verification mode and a full-process verification mode; the verification instructions include a review-only verification instruction, a preview verification instruction and a full-process verification instruction.

[0100] After the operation ticket preview is completed, the centralized control system sends the operation ticket execution command to the sequential control host via the mirror switch and the backup gateway. The sequential control host receives and parses the command and starts the execution operation. It sends the remote control command to the bay layer device simulation software in sequence according to the operation steps in the operation ticket.

[0101] The bay layer device simulation software receives the remote control command sent by the sequence control host, searches for the correspondence between the received remote control point and the remote signal from the one-key sequence control parameters of the software, and sets the remote signal state corresponding to the remote control to the corresponding state to meet the execution conditions of the next operation step, otherwise the next operation step will fail due to the failure to meet the pre-execution conditions;

[0102] The centralized control system issues the execution command of the operation ticket, and the control host responds and starts the execution operation, and issues the remote control command in sequence according to the operation steps in the operation ticket; the bay layer device simulation software receives the remote control command and sets the remote signal state corresponding to the remote control to meet the execution conditions of the subsequent operation steps;

[0103] After all the operation steps in the operation ticket are executed, the sequential control host generates the total result of the successful execution of the operation ticket and sends it to the centralized control system through the backup gateway machine and the mirror switch;

[0104] The message monitoring and parsing software monitors and parses the successful execution total result message sent to the centralized control system via the mirrored network port of the mirrored switch, and determines that the execution of the operation ticket is completed;

[0105] S5: Call the next unread operation ticket in the current interval;

[0106] S6: Determine whether all operation tickets of the current interval have been verified; if not, repeat S5; if all operation tickets of the interval have been verified, the centralized control system starts the verification of the next unverified interval in the interval list;

[0107] S7: Determine whether all interval operation tickets have been verified; if not, repeat S2; if completed, the verification ends.

[0108] Example 2

[0109] This embodiment is described in conjunction with Example 1. This embodiment discloses a master-substation one-key sequential control non-stop automatic calibration system, including a main gateway machine, a standby gateway machine, a dispatching master station system, a centralized control system, a sequential control host, a protection device, a measurement and control device, a mirror switch, an interval layer device simulation software and a message monitoring and analysis software.

[0110] The main gateway machine communicates with the dispatching master station system to interact with the main substation; the protection device and the measurement and control device communicate with the main gateway machine through the station control layer network;

[0111] The standby gateway machine communicates with the centralized control system through the mirror switch to perform master-substation communication. The message monitoring and parsing software is connected to the mirror network port of the mirror switch. The interval layer device simulation software communicates with the standby gateway machine and the sequential control host through the debugging network. The message monitoring and parsing software communicates internally with the interval layer device simulation software.

[0112] The spacing layer device simulation software simulates a virtual protection device and a virtual measurement and control device in the debugging network. The parameters and communication behavior of the virtual protection device are consistent with those of the protection device in the operating network, and the parameters and communication behavior of the virtual measurement and control device are consistent with those of the measurement and control device in the operating network.

[0113] In this embodiment, the system and method shown can be implemented in other ways. For example, the main gateway machine or the newly added replacement gateway machine is used to access the debugging network with the sequential control host for verification, or the function is directly expanded on the gateway machine to enable it to have the message monitoring and parsing functions for verification, or the mirror forwarding of the message is realized by modifying the mirror configuration on the original main substation communication switch for verification, or a certain number of real protection, measurement and control devices or other tester devices with similar functions are used to replace the interval layer device simulation software for verification, or a device or tester device with message monitoring and parsing functions is used to replace the message monitoring and parsing software for verification, etc. Various modifications to this embodiment are very easy for professionals in this field, and the general principles defined in this embodiment can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown in this article, but will conform to the widest range consistent with the principles and novel features disclosed in the present invention.
