[0062] Figure 3 This is a flow chart of a communication information detection method according to an embodiment of the present application.

[0063] S31, parsing the communication information of multiple communication layers to obtain parsing result information corresponding to each communication layer.

[0064] Specifically, the terminal equipment deployed in the substation for communication monitoring and data quality monitoring can obtain the communication messages of each communication layer of the substation through communication. In the embodiment of the present application, according to the fully digital intelligent substation architecture, the device layer includes the dispatching master station layer 210, the substation station control layer 220, the substation interval layer 230, and the substation interval layer 240, and the collected communication layers include the dispatching communication layer 211, the interval communication layer 221, and the process communication layer 231. The communication protocol adopted by the dispatching communication layer 211 is DL / T634.5104. The protocol adopted by the interval communication layer 221 is the IEC61850-MMS protocol. The protocol adopted by the process communication layer 231 is the IEC61850-SV protocol and the IEC61850-GOOSE protocol.

[0065] In the embodiment of the present application, the communication unified model, the IEC61850 standard modeling model is used as the communication model in the substation, which is applicable to the interval communication layer 221 and the process communication layer 231. The dispatching communication layer 211 adopts the DL / T634.5104 protocol as the communication point table model. The information point table of the dispatching point table model of the dispatching communication layer 211 is associated with the IEC61850 model to establish a substation communication information association model. In this embodiment, the association method uses the signal type + information point sequence number of the dispatching point table model of the dispatching communication layer 211 and the reference of the IEC61850 model to achieve the establishment of the substation communication information association model. The collected messages of each communication layer of the substation are parsed according to their corresponding communication protocols, and the messages of the interval communication layer 221 and the process communication layer 231 in the station are parsed into the measurement data or operation control instructions of the information point of the IEC61850 model, and the messages of the dispatching communication layer 211 are parsed into the measurement data or operation control instructions of the signal type + information point sequence number of the dispatching point table model. An information point refers to a communication record about a communication information. The information point table includes a plurality of information points.

The information point table model corresponds to the substation electrical information. The substation electrical information generally adopts the CIM electrical model, and the corresponding CIM electrical model can be associated with the type of information point table and the information point sequence number. There is no direct correspondence between the CIM electrical model and the IEC61850 model. It is necessary to perform information association analysis between the two through the association relationship established by the association model to obtain the analysis result information corresponding to the dispatching communication layer 211.

[0067] The interval communication layer 221 between the substation control layer 220 device and the substation interval layer 230 device usually adopts the IEC61850-MMS communication protocol. In the IEC61850-MMS communication of the interval communication layer 221, the measurement data is transmitted in the form of reports, and the transmission content is the report name, the serial number in the report and the corresponding measurement value. The association analysis between the communication transmission content and the information point is realized through the association relationship between the report name, content and signal point in the model, and the analysis result information corresponding to the interval communication layer 221 is obtained. The operation control instruction of the interval layer communication layer 221 directly transmits the information point reference, which can be directly associated with the corresponding information point of the model.

[0068] The process communication layer 231 between the substation bay layer 230 device and the substation process layer 240 device usually adopts the IEC61850-SV and IEC61850-GOOSE communication protocols. The IEC61850 information model is used inside the substation, and the information points are fully described as reference descriptions in the model; the communication layer transmission model is included in the information model. In the IEC61850-SV and IEC61850-GOOSE communications of the process communication layer 231, information transmission is carried out in a reporting manner, and the transmission content is the report name and the current value of all the information points in the report. The information point association is parsed through the association relationship between the registration name and the report information point in the model, and the parsing result information corresponding to the process communication layer 231 is obtained.

[0094] In one embodiment, the cross-layer detection result includes a cross-layer tracing detection result, and the one or more layer detection results are determined according to the parsing result information corresponding to each communication layer, including:

[0095] Determine, according to the parsing result information of the scheduling communication layer, the scheduling communication layer outbound uplink communication information belonging to the predetermined uplink mode in the scheduling communication layer;

[0096] Determine the interval communication layer outbound uplink communication information and the process communication layer outbound uplink communication information corresponding to the scheduling communication layer outbound uplink communication information;

[0097] The outbound communication information sent up by the scheduling communication layer, the outbound communication information sent up by the interval communication layer, and the outbound communication information sent up by the process communication layer are compared to determine the cross-level traceability detection result.

[0098] S31, the communication information of multiple communication layers is parsed to obtain the parsing result information corresponding to each communication layer. The communication layer can be used as a data identifier, sorted and incorporated into the information point update data, and form the information point update data with the communication layer identifier. The content of the sorted information point update data includes but is not limited to: information point type, information point model information, information point update communication layer identifier, information point update time, information point update value, etc. For example, the content of the information point update data includes: the information point type is remote signal, the information point model information is 61850Reference (such as CM3502LD0 / DevAlmGGIO1$ST$Alm1), the information update communication layer identifier is the substation control layer 220, the information point update time is 2024-8-5 15:01:23 356, and the information point update value is combined.

[0099] S32, according to the parsing result information of the scheduling communication layer, determine the outbound uplink communication information of the scheduling communication layer that belongs to the predetermined uplink mode in the scheduling communication layer. The outbound uplink communication information of the scheduling communication layer that belongs to the predetermined uplink mode in the scheduling communication layer includes the information point update data that belongs to the predetermined uplink mode in the scheduling communication layer. Among them, the predetermined uplink mode includes but is not limited to burst uplink and variable uplink. According to the parsing result information of the scheduling communication layer, determine the outbound uplink communication information of the scheduling communication layer that belongs to the burst uplink or variable uplink mode in the scheduling communication layer. Take the measurement value information sent by the scheduling communication layer in burst uplink or variable uplink mode as the monitoring object, and monitor the measurement value information sent by the scheduling communication layer in burst uplink or variable uplink mode. The communication message is parsed and processed at the dispatching communication layer. If it is found that the uploading method or the uploading reason is a measurement value of a burst uploading method or a variable uploading method, the update data of the corresponding information point measurement value uploading is sorted and obtained. The content of the sorted information point measurement value uploading update data includes the information point type, information point model information, information point update time, information point update value, etc. After monitoring the measurement value information uploaded by the dispatching communication layer in a burst uploading method or a variable uploading method, the sorted information point update data is checked in order from high to low in the communication layer within the station to determine the outbound uploading communication information of the interval communication layer and the outbound uploading communication information of the process communication layer corresponding to the outbound uploading communication information of the dispatching communication layer. The outbound uploading communication information of the dispatching communication layer, the outbound uploading communication information of the interval communication layer, and the outbound uploading communication information of the process communication layer are compared to determine the cross-level traceability detection result. When making a comparison, first retrieve the corresponding communication layer, then retrieve the corresponding data with the information point type and information point model information, and compare and check the information point update time and information point update value. The information point update time stamp should be consistent, and the information point update value should correspond. If the comparison and verification fails, record the corresponding information and related data, determine it as a cross-level traceability test result, and send the cross-level traceability test result to the user in S33. In addition, an alarm prompt can also be sent to the user.

[0100] In one embodiment, the parsing result information corresponding to each communication layer includes the measurement values ​​of one or more information points corresponding to each communication layer, and the cross-layer detection result includes the cross-layer measurement value detection result. The determining one or more layer detection results according to the parsing result information corresponding to each communication layer includes:

[0101] A cross-layer comparison test is performed on the measurement values ​​of one or more information points respectively corresponding to each communication layer to determine a cross-layer measurement value test result.

[0102] The measurement values ​​of one or more information points corresponding to each communication layer in the communication model are compared and detected across different communication layers. If the measurement values ​​of the same information point are found to be inconsistent in each communication layer, records and alarms are issued to determine the cross-layer measurement value detection results. The measurement values ​​of one or more information points in each communication layer may have a value conversion relationship according to the communication model. After the value conversion process, the measurement values ​​of the same information point in each communication layer should correspond.

[0103] In one embodiment, a cross-layer comparison test is performed on the measurement values ​​of one or more information points corresponding to each communication layer according to a certain time period to determine the cross-layer measurement value test result. The time period is settable.

[0104] In one embodiment, cross-layer comparison detection is performed on the measurement values ​​of one or more information points corresponding to each communication layer to determine the cross-layer measurement value detection result, including:

[0105] A delayed cross-layer comparison test is performed on the measurement values ​​of one or more information points corresponding to each communication layer to determine the cross-layer measurement value test results.

[0106] In order to avoid the short-term mismatch of data in each communication layer due to the communication process, a delayed cross-layer comparison test can be performed for the case where the measured values ​​of one or more information points found in the cross-layer comparison test do not correspond to the values ​​of the values ​​in different communication layers. Within the set delay time, if the mismatch of the measured values ​​of one or more information points in different communication layers is eliminated, it means that the mismatch of values ​​between different communication layers is caused by the communication process and is considered normal. The delay time of the delayed cross-layer comparison test can be set.

[0107] In one embodiment, the cross-layer detection result includes a cross-layer time interval detection result, and the same-layer detection result includes a same-layer time interval detection result. The one or more layer detection results are determined according to the parsing result information corresponding to each communication layer, including:

[0108] According to the analysis result information respectively corresponding to each communication layer, a cross-layer time interval detection result and / or a same-layer time interval detection result in which no data refresh occurs for more than a predetermined time interval is determined.

[0109] Here, the predetermined time interval can be set in advance or adjusted at any time. For example, periodic detection can be performed based on the predetermined time interval set in advance, and the cross-level time interval detection results and / or the same-level time interval detection results for which no data refresh occurs for more than the predetermined time interval are determined in each cycle. The predetermined time interval for periodic detection can be set according to the type of measurement value information point and / or the different communication layer protocol conditions. For another example, the predetermined time interval can be adjusted at any time according to the type of measurement value information point and / or the actual operation of the substation.

[0110] The analysis result information corresponding to each communication layer includes measurement value information points. The measurement value information points corresponding to each communication layer can be detected. If it is found that the time interval corresponding to the measurement value information point exceeds the predetermined time interval and the data is not refreshed, the cross-level time interval detection result and / or the same-level time interval detection result are determined, and recorded and alarmed.

[0111] In one embodiment, the parsing result information corresponding to each communication layer includes one or more operation control instructions corresponding to each communication layer, the cross-layer detection result includes a cross-layer control instruction detection result, and the same-layer detection result includes a same-layer control instruction detection result. The one or more layer detection results are determined according to the parsing result information corresponding to each communication layer, including:

[0112] An operation process comparison detection is performed on one or more operation control instructions corresponding to each communication layer to determine a cross-level control instruction detection result and / or a same-level control instruction detection result.

[0113] S31, the communication information of multiple communication layers is parsed to obtain the parsing result information corresponding to each communication layer. Here, the parsing result information corresponding to each communication layer includes the operation control instructions corresponding to each communication layer. The source of the operation control instruction may be a device at the dispatching master station layer, or it may be a device at the substation control layer. By detecting the operation control instructions in the dispatching communication layer and the interval communication layer, the source operation control instructions can be discovered in time, and the transmission and execution process of the operation control instructions in each communication layer and device layer can be detected in time. When the dispatching communication layer and the interval communication layer are detected and new commands are sent, the operation control instructions can be parsed and sorted for operation process monitoring. The parsed and sorted operation control instructions include but are not limited to the operation object information point type, operation control information point model information, operation control type, operation control step, operation control parameters, etc.

[0114] S32, performing operation process comparison detection on one or more operation control instructions corresponding to each communication layer, and determining a cross-layer control instruction detection result and / or a same-layer control instruction detection result.

[0115] Specifically, in the present embodiment, in the fully digital intelligent substation, the operation control instructions include but are not limited to the dispatching operation control instructions and the station control layer operation control instructions. Among them, the dispatching operation control instructions are transmitted through the dispatching communication layer, the interval communication layer, and the process communication layer in sequence. The dispatching communication layer is the IEC-60870-104 protocol remote control and remote adjustment instructions, the interval communication layer is the IEC61850-MMS control command, and the process layer is the IEC61850-GOOSE instruction. The station control layer operation control instructions are transmitted through the interval communication layer and the process communication layer in sequence. The interval communication layer is the IEC61850-MMS control command, and the process layer is the IEC61850-GOOSE instruction.

[0116] After parsing the messages of each communication layer during the transmission of the operation control instruction, one or more operation control instructions corresponding to each communication layer are obtained. The data content of the operation control instruction includes the communication layer identification, the operation control instruction type, the operation control information point communication model information, the operation object information point type, and the operation control step.

[0117] Operation control instructions include two types: selection control and direct control. In the selection control mode, you first select and then execute. After the selection, you can execute or cancel. In the direct control mode, you can directly execute the control.

[0118] In the selection control mode, the complete path of the dispatching operation control command is as follows. Select: Dispatching communication layer operation control selection command -> Substation interval communication layer operation control selection command -> Substation interval communication layer operation control selection return -> Dispatching communication layer operation control return. Execute: Dispatching communication layer operation control execution command -> Substation interval communication layer operation control execution command -> Substation process communication layer operation control command -> Substation interval communication layer operation control execution return -> Dispatching communication layer operation execution return. Cancel: Dispatching communication layer operation control cancel command -> Substation interval communication layer operation control cancel command -> Substation interval communication layer operation control cancel return -> Dispatching communication layer operation cancel return.

[0119] In the selected control mode, the complete path of the substation station control layer operation control command is as follows. Select: Substation interval communication layer operation control selection command -> Substation interval communication layer operation control selection return. Execute: Substation interval communication layer operation control execution command -> Substation process communication layer operation control command -> Substation interval communication layer operation control execution return. Cancel: Substation interval communication layer operation control cancel command -> Substation interval communication layer operation control cancel return.

[0120] In direct control mode, the complete path of the dispatching operation control command is as follows: Execution: Dispatching communication layer operation control execution command -> Substation interval communication layer operation control execution command -> Substation process communication layer operation control command -> Substation interval communication layer operation control execution return -> Dispatching communication layer operation execution return.

[0121] In direct control mode, the complete path of substation station control layer operation control instructions is as follows: Execution: Dispatching communication layer operation control execution instruction -> Substation interval communication layer operation control execution instruction -> Substation process communication layer operation control instruction -> Substation interval communication layer operation control execution return -> Dispatching communication layer operation execution return

[0122] Perform a comparative test on the operation process of one or more operation control instructions corresponding to each communication layer to determine the cross-level control instruction test results and / or the same-level control instruction test results. The operation control instruction transmission process can be path-checked according to the above-mentioned subdivided command path, and check whether the operation object information point type, operation control type, and operation control steps in the operation control instruction transmission process are consistent. If the operation object information point type, operation control type, and operation control step in the operation control instruction transmission process are inconsistent, it is an operation control error, which is recorded and an alarm is issued. If the path is interrupted or a path error occurs during the transmission process, it is an operation control failure, which is recorded and an alarm is issued.

[0123] In one embodiment, the parsing result information corresponding to each communication layer includes analog measurement values ​​of one or more information points corresponding to each communication layer, the cross-layer detection result includes a cross-layer analog measurement value detection result, and the same-layer detection result includes a same-layer analog measurement value detection result. The one or more layer detection results are determined according to the parsing result information corresponding to each communication layer, including:

[0124] Comparative detection is performed on the analog measurement values ​​of one or more information points respectively corresponding to each communication layer to determine the cross-layer analog measurement value detection result and / or the same-layer analog measurement value detection result.

[0125] In the field of power system communication, there are two types of information point analog measurement values ​​and digital measurement values. For example, the switch position and other state quantities are digital measurement values ​​of information points. Current value, voltage value, electricity value, etc. are analog measurement values ​​of information points.

[0126] The manner of performing comparative detection on the analog measurement values ​​of one or more information points respectively corresponding to each communication layer includes, but is not limited to, mutation comparative detection, restriction comparative detection, etc. The following will respectively describe them.

[0127] 1) Mutation comparison detection.

[0128] Specifically, after parsing and obtaining the analog measurement values ​​of one or more information points corresponding to each communication layer, the set first threshold value for mutation comparison detection and the second threshold value for mutation comparison detection are obtained according to the information point model related information, and the current data of the analog measurement values ​​of one or more information points and the last updated data are calculated to obtain the analog measurement mutation values ​​of one or more information points. The analog measurement mutation values ​​of one or more information points are compared with the set first threshold value for mutation comparison detection and the second threshold value for mutation comparison detection. If the analog measurement mutation values ​​of one or more information points exceed the set first threshold value for mutation comparison detection or the second threshold value for mutation comparison detection, it is determined that a numerical mutation occurs, that is, the cross-level analog measurement value detection result and / or the same-level analog measurement value detection result are determined. If the mutation value does not exceed the set threshold value, it is determined that there is no abnormality. After the determination is completed, the update data of the information point is updated.

[0129] The first threshold of the mutation comparison detection can be set according to the rated value of the measurement data and a certain ratio.

[0130] Specifically, in this embodiment, the first threshold for mutation comparison detection is set for the substation telemetry information and the remote pulse information in proportion. For example, the first threshold for mutation comparison detection of telemetry information is set to 5% of the rated value of the measurement data, and the first threshold for mutation comparison detection of remote pulse information is set to 2% of the rated capacity of the transformer.

[0131] The second threshold value for mutation comparison detection can be set as an absolute value according to the actual operation status of the measurement data.

[0132] Specifically, in this embodiment, the substation telemetry information is further subdivided into current value, voltage value, and power value, and the second threshold for mutation comparison detection is set in sequence. The remote pulse information is further subdivided into electricity value and power value. The second threshold for mutation comparison detection of the telemetered current value can be set to a value corresponding to the primary value 100A. The second threshold for mutation comparison detection of the telemetered voltage value can be set to a value corresponding to the primary value 500V. The second threshold for mutation comparison detection of the telemetered power value can be set to a value corresponding to the primary value 1000W / VA. The second threshold for mutation comparison detection of the remote pulse electricity value can be set to a value corresponding to the primary value 1000W.h / VA.h. The second threshold for mutation comparison detection of the remote pulse power value can be set to a value corresponding to the primary value 1000W / VA.

[0133] 2) Limit contrast testing.

[0134] Comparative detection is performed on the analog measurement values ​​of one or more information points respectively corresponding to each communication layer to determine the cross-layer analog measurement value detection result and / or the same-layer analog measurement value detection result.

[0135] Here, a corresponding limit contrast detection threshold value may be set for the analog measurement value of one or more information points, and the limit contrast detection threshold value may be an upper limit value or a lower limit value. The limit contrast detection threshold value may be set based on the rated value of the analog measurement value of one or more information points, or may be set based on the rated value of the analog measurement value of one or more information points according to a certain percentage ratio.

[0136] The analog measurement values ​​of one or more information points corresponding to each communication layer are compared with the limit comparison detection threshold to determine the cross-level analog measurement value detection result and / or the same-level analog measurement value detection result. If the analog measurement value of one or more information points exceeds the limit comparison detection threshold, it is recorded and an alarm is issued, that is, the cross-level analog measurement value detection result and / or the same-level analog measurement value detection result are determined.

[0137] In one embodiment, the parsing result information corresponding to each communication layer includes the measurement status of one or more information points corresponding to each communication layer, the cross-layer detection result includes the cross-layer measurement status detection result, and the same-layer detection result includes the same-layer measurement status detection result. The one or more layer detection results are determined according to the parsing result information corresponding to each communication layer, including:

[0138] A displacement detection is performed on the measurement status of one or more information points respectively corresponding to each communication layer to determine a cross-layer measurement status detection result and / or a same-layer measurement status detection result.

[0139] S31, the communication information of multiple communication layers is parsed, and the parsing result information corresponding to each communication layer can be obtained. The displacement state and displacement time of the corresponding information point are obtained according to the communication model. The displacement time can be standardized into time stamp information in a unified format. The displacement time has different time formats in different communication protocols, some of which use UTC time stamp, some use year-month-day-hour-minute-second character string or numerical value, and some use incomplete year+month-day-hour-minute-second character string or numerical value. The displacement time can be standardized to obtain time stamp information in a unified format. The unified format can use UTC time stamp or year-month-day-hour-minute-second numerical information, with complete content and concise storage. The displacement state can be standardized into a dual-position state. In addition, for the synthetic dual-position signal, it is necessary to obtain the state of another synthetic signal source for processing. The information point state displacement information with time stamp after standardization is classified according to the communication model information point, and sorted according to the time stamp order to form a specific information point state displacement sequence.

[0140] S32, performing displacement detection on the measurement status of one or more information points corresponding to each communication layer, and determining a cross-layer measurement status detection result and / or a same-layer measurement status detection result.

[0141] The methods of displacement detection include but are not limited to: intermediate state monitoring, abnormal state monitoring, jitter monitoring, etc.

[0142] The measurement status of one or more information points can be a single-position signal, a dual-position signal, or a composite dual-position signal. A single-position signal refers to a state signal that obtains the current state of a switch by collecting the open position or closed position state of the switch. A dual-position signal refers to a state signal that obtains the current state of a switch by collecting the open position and closed position states of the switch at the same time. A composite dual-position signal refers to an artificial synthesis of the closed position state and open position state of the switch collected in the form of a single-position signal into a dual-position signal.

[0143] For example, during the switch state change process of the dual-position signal, due to the asynchronous change of the open position and the closed position state, an intermediate state will appear in the change process, which is called the intermediate state. Intermediate state monitoring is used to monitor the intermediate state of the dual-position signal change. Intermediate state monitoring only needs to select the last three state change information, and intercept the last three state changes from the information point state change sequence as the data segment of the change monitoring module. The intermediate state monitors the intermediate state of the dual-position signal change process, determines the cross-level measurement state detection results and / or the same-level measurement state detection results, and gives prompts and records after discovery, but does not treat it as an abnormality and does not alarm.

[0144] For another example, the open position state and the closed position state of the dual-position signal should be opposite. When the switch is in the closed state, the corresponding open position and closed position states are open and closed respectively. When the switch is in the open state, the corresponding open position and closed position states are closed and open respectively. If the dual-position signals of a switch are in the open state at the same time, it is called "double open". If the dual-position signals of a switch are in the closed state at the same time, it is called "double closed". Both the "double open" and "double closed" states are abnormal states, called abnormal states. Abnormal state monitoring only needs to select the last three state change information, and intercept the last three state changes from the information point state change sequence as the data segment of the change monitoring module. Abnormal state monitoring is used to monitor the abnormal state of the dual-position signal. When a non-intermediate double open or double closed state occurs during the dual-position signal change process, it is determined that an abnormal state has occurred, recorded and alarmed, and the cross-level measurement state detection results and / or the same-level measurement state detection results are determined.

[0145] For another example, jitter monitoring is used to monitor the repeated changes of status signals in a short period of time. Jitter monitoring is judged by time period, and the information point state change sequence segment is intercepted by time period. In this embodiment, the information point state change sequence within the last 5 minutes is intercepted as the data segment for change monitoring. Jitter monitoring monitors the repeated changes of status signals in a short period of time. In this embodiment, the number of changes within 3 minutes is used for judgment. If the number of changes exceeds 5 times, it is determined that jitter occurs, recorded and alarmed, and the cross-level measurement status detection results and / or the same-level measurement status detection results are determined.

[0146] The displacement detection is performed on the measurement status of one or more information points corresponding to each communication layer, and the information point state displacement sequence after standard serialization is used as the processing object. However, if the entire information point state displacement sequence is used as the processing object, it will cause redundant calculation problems and affect the real-time performance of data processing. To solve this problem, when performing displacement detection processing, the information point state displacement sequence segments required by each requirement are first selected for processing according to the specific displacement monitoring requirements, which can reduce redundant calculations and improve the real-time performance of data processing.
