[0040] The following is further explained in detail through specific implementation methods.

[0041] like Figure 1 As shown, the present application provides a twin system operation tracking method, comprising:

[0042] S100, obtaining the current device status of the unit and the basic device status of all devices in the digital twin system, and comparing the basic device status of all devices in the digital twin system with the current device status of the unit to obtain a list of devices to be initialized;

[0044] S300, obtaining a DCS log, parsing an operation log in the DCS log to generate a sample in a preset format;

[0045] S400. Generate an operation sequence based on the sample, and perform simulation operations on all devices of the initialized digital twin system according to the operation sequence.

[0046] In one embodiment, the historical data of the unit is parsed and reconstructed to achieve the playback of the unit's transient process to the operator station. The playback content includes the equipment status, relevant parameter changes, logs and alarms in the screen, which can fully reproduce the state of the unit's human-machine interface at the transient moment. Relying on the unit's operating data for many years, the operating data can be divided into different scenes according to the timeline. The operating personnel can 100% reproduce the state of the unit at the corresponding moment by selecting the corresponding scene. It is closer to the actual situation than the working conditions simulated by the simulator. The transient process is comprehensively analyzed to summarize experience feedback, provide improvement directions, and then carry out training to improve the operating personnel's ability to handle abnormal transient and accident conditions, so as to achieve the purpose of improving the safe and stable operation of the unit. It can also assist in the analysis of the cause of the event and improve the efficiency of the analysis of the cause of the unit accident.

[0047] In some embodiments, step S100 is to make the current device state of the unit consistent with all device states in the digital twin system, so that the operation process under the same state can be fully reproduced. Optionally, the device state (device state, referred to as DSTA) in the DCS system is divided into 9 categories: fully open (open / close), fully closed (stop / open), opening, closing, intermediate position, open fault, close fault, intermediate position fault, other faults; the basic device state (basic device state, referred to as BSTA) is divided into 4 categories: fully open (open / close), fully closed (stop / open), intermediate position, fault. The relationship between the two is shown in the following table:

[0048]

[0049]

[0050] The equipment status code stored in the ADACS_N system database is the "basic equipment status code". The computing server of the digital twin system also calculates the equipment BSTA. By traversing all the equipment in the digital twin system, obtaining the BSTA and comparing it with the equipment status of the unit at the current moment, the list of equipment to be initialized can be obtained. The BSTA of the unit equipment is the initial target state that each device in the simulation model wants to achieve.

[0051] In some embodiments, after obtaining the list of initialized devices, all devices of the digital twin system can be initialized according to the list to ensure that the status of the device is consistent with the basic status of the unit before the operation command is executed. Optionally, the operation objects can be divided into 11 categories: AIR_OP_DAMPER, BINARY_ACTUATOR, BLOCK_VALVE, BLOCK_STP_VALVE, SOL_VALVE_FO, SOL_VALVE_FC, LOOP_CONTROL, LOOP_VALVE_FO, LOOP_VALVE_FC, SELECTOR, MULTI_COMMANDS. In order to simplify the model, the initialization objects are abstracted into 3 categories, namely ordinary switch devices, regulating valves, and group control switches and selectors, as shown in the following table:

[0052]

[0053]

[0054] In some embodiments, when the operation type is a common switch type device, the device status initialization processing method is:

[0055] Sending a manual command to a common switch type device to switch the common switch type device to a manual state;

[0056] Based on the initial target state of the common switch type device, a corresponding operation instruction is sent to the common switch type device so that the common switch type device reaches the initial target state;

[0057] When the common switch type device reaches the initial target state, the common switch type device is switched to the automatic state.

[0058] In one embodiment, for common switch-type devices, the manual / automatic status of each PO in the digital twin system is remembered before initialization, and then the CIN_5 command is sent to switch all POs to the manual state. At this time, the device can be controlled by external operation commands. According to the target state, the CIN_1 or CIN_2 command is sent to turn on or off the device, and finally the device whose initial state is automatic is switched back to the automatic state.

[0059] In some embodiments, when the operation type is a regulating valve, the initialization processing method of the device state is:

[0060] Sending an output regulation command to the regulating valve to switch the regulating valve to an open-loop regulation state;

[0061] Based on the initial target state of the regulating valve, a corresponding regulating instruction is sent to the device so that the regulating valve reaches the initial target state, wherein when the regulating valve is a switch valve, the initial target state is open or closed, and when the regulating valve is a valve with a valve opening, the initial target state is a target valve position;

[0062] When the control valve reaches the initial target state, the control valve is switched to the closed-loop control state.

[0063] In one embodiment, for the regulating valve, according to the ADACS_N system historical data storage mechanism, it is divided into two categories: regulating valves with target valve positions and regulating valves with only switch status. Before initializing the regulating valve, remember the open / closed-loop regulation status of each PO of the prototype, and send the CIN_8 command to switch all POs to the open-loop regulation state. For the regulating valve with only the switch status, adjust the valve position to 0 or 100; for the regulating valve with the target valve position, adjust the valve position to the target valve position, and then the simulation model calculates the set value input of the PID in the closed-loop regulation mode through the target valve position to avoid disturbance of the PID module when the regulating valve is switched back to the closed-loop regulation mode. Finally, the device whose initial state of the prototype is closed-loop regulation is switched back to the closed-loop regulation state.

[0064] In some embodiments, when the operation type is a group control switch or a selector, the initialization processing method of the device state is:

[0065] The group control switch or selector is initialized based on a preset configuration file, wherein the configuration file includes an operation object, an operation type, a precondition, and a postcondition.

[0066] In one embodiment, the initialization of the group control switch (KG) and the selector (KC) is generally used for switching between columns of devices that serve as backup for each other, and KC and KG are not initialized separately. Since some devices have some signal locks when turning on / off, it is necessary to release the lock signals through KC and KG to operate the devices. For this situation, a configuration file is designed to handle such POs containing complex logic. The configuration file contains the operation object, operation type, preconditions and postconditions. The initialization program first operates the corresponding object according to the preconditions; then performs predefined operations on the operation object; and finally operates the corresponding object according to the postconditions. The configuration file style is shown in the following table:

[0067]

[0068] In some embodiments, in step S300, the DCS log can be obtained online or offline. Optionally, the DCS log can be stored in a tape drive. As a traditional data storage device, the tape drive has the advantages of low storage cost, not easy to be infected by viruses, and not easy to damage data. It is suitable for long-term storage of large amounts of infrequently accessed data. Therefore, it is widely used in nuclear power plant DCS systems to store historical data. The log history data of a nuclear power plant is usually stored on a daily basis. At 00:00:00 every day, the operation log of the previous day is automatically written into a text file and named with the date. The required log history data can be retrieved through the file name. In addition, real-time logs can also be exported by users authorized by the nuclear power plant using specific interfaces or tools. After the unit log is exported, it is stored in the data center where the digital twin is running.

[0069] In some embodiments, the DCS log includes multiple logs. Specifically, the DCS log can be divided into the following types according to their functions:

[0070] Equipment status log: The equipment status log is used to record status information related to process system equipment.

[0071] Tagout log: The tagout log stores information related to tagout operations, including the tagout and de-tagout status of the equipment, the type of tagout, the isolation tag number, isolation ticket number, work ticket number, etc.

[0072] Shift handover log: stores operator login information and shift handover information.

[0073] Alarm log: The alarm log records the information of alarm generation and recovery, alarm suppression generation events, alarm suppression recovery events, alarm storage and alarm confirmation.

[0074] Procedure log: The procedure log records information related to procedure operations.

[0075] Operation log: used to record the operator's operation information, including variable force, parameter modification (such as alarm limit), manual server switching operation, manual shutdown request operation, archiving request, equipment start and stop, reset, and parameter setting operation information.

[0076] System log: stores DCS system log, including instrumentation system information, first and second layer equipment status and fault information, such as communication network, server switching and other equipment status information, system exit information, external clock invalid information, etc.

[0077] Temporary variable log: The variable temporary monitoring log stores the occurrence and recovery of alarms temporarily defined online by the operator.

[0078] Among them, the DCS log contains information such as timestamp, object name (KKS code), object description, log type, log description, operator station number, operator login account, etc. The operation log in the DCS log can be filtered out by log type, and the event time and operation type can be determined according to the timestamp and operation description. Then, the operation log of the selected time period is parsed and saved as a sample.

[0079] In some embodiments, the sample in the preset format is a sample that at least includes the time when the crew operation event occurs, the object name of the operation object, the description of the operation object, the operation type description, the operator login account and the operation command position number.

[0080] In one embodiment, the time when the unit operation event occurs is represented by a 13-bit timestamp, the object name of the operation object is the KKS code of the operation object, and the operation command bit number represents the number corresponding to the specific operation command, for example, for a valve, 1 represents an open command, and 2 represents a close command; for a selector, 3 represents MODE1, and 4 represents MODE2. By setting the sample to a specific format, the embodiment of the present application can parse the required content in the sample.

[0081] In some embodiments, step S400 specifically includes:

[0082] The timestamp corresponding to the first operation object in the sample is used as the starting time, the time interval of each operation is calculated, and the operation sequence is generated based on the time interval and the sample;

[0083] Generate operation commands based on the operation sequence, and perform simulation operations on all devices of the initialized digital twin system based on the operation commands.

[0084] In one embodiment, after the operation tracking starts, the timestamp corresponding to the first operation object in the corresponding operation log sample is defined as the start time, the time interval of each operation is calculated, and the operation sequence is generated. Through the external interface (redisrworker) provided by the twin simulation model, the values ​​of the first and second layer command interface variables are modified in sequence according to the operation sequence, realizing automatic control of the device.

[0085] In some embodiments, the method further comprises:

[0086] The device state feedback value after the simulation operation is obtained, and the device state feedback value after the simulation operation is compared with the actual state of each operation object to obtain a simulation evaluation result.

[0087] In one embodiment, after the operation command is issued, the device status feedback value is obtained. The BSTA value can not only determine whether the operation command is executed successfully, but also compare whether the status of the operation object is consistent with the unit.

[0088] In addition, the present application also provides a twin system operation tracking device, such as Figure 2 As shown, the twin system operation tracking device includes a log parsing module 11, a list acquisition module 12, an initialization module 13 and a solution running module 14.

[0089] The list acquisition module 11 is used to obtain the current equipment status of the unit and the basic equipment status of all equipment in the digital twin system, and compare the basic equipment status of all equipment in the digital twin system with the current equipment status of the unit to obtain a list of equipment to be initialized.

[0090] The initialization module 12 is used to initialize the basic status of all devices in the digital twin system based on the list of devices to be initialized.

[0091] The log parsing module 13 is used to obtain the DCS log and parse the operation log in the DCS log to generate a sample in a preset format.

[0092] The simulation module 14 is used to generate an operation sequence based on the sample, and perform simulation operations on all devices of the initialized digital twin system according to the operation sequence.
