The second relay protection information system may send the operation data response message to the first relay protection information system. The format of the operation data response message may be a message format of an existing communication protocol, which is not limited in this disclosure.
The operation data files can be divided into a plurality of types according to contents, and each operation data file can correspond to one relay protection data type. For example, the fault data corresponds to an operation data file, and the alarm data of the relay protection device corresponds to an operation data file. As long as each operation data file can describe clearly what type of relay protection data corresponds to, the present disclosure does not limit the specific content of each operation data file.

Fig. 3 shows a flowchart of a relay protection data transmission method between relay protection information systems according to an embodiment of the present disclosure. As shown in fig. 3, in one possible implementation, the method may further include:
and step S13, pre-configuring the format of the operation data request message corresponding to the relay protection data type.
The relay protection information system of the scheduling mechanism can pre-configure the format of the operation data request message corresponding to each relay protection data type according to the relay protection data type.
For example, the relay protection data may be divided into a plurality of types, such as fault data, relay protection device operation data, relay protection device setting value, relay protection device event data, relay protection device alarm data, relay protection device switching value displacement data, relay protection device switching value current state, relay protection device soft pressing plate displacement data, relay protection device soft pressing plate current state, and the like.

The operation data of the relay protection device may be operation data of one relay protection device, such as an operation report, when a primary equipment in the power grid fails. The action data of the relay protection device can comprise a plurality of event signals and a wave recording file.
The relay protection device setting value can be an action setting value arranged in the relay protection device and is matched with the protection logic to complete the relay protection function. A relay protection device may have multiple fixed values. For example, "overcurrent I-section outlet current constant".
The relay protection device event data may be an operation signal amount generated after the relay protection device is operated, for example, "differential outlet".
The relay protection device alarm information may refer to a semaphore that the relay protection device itself is abnormal. Such as "potential transformer pt (potential transformer) disconnection".
The switching value bit data of the relay protection device can be a signal value of switching value change acquired in the operation of the relay protection device. For example, "channel experiments are changed from closed to open".
The current state of the switching value of the relay protection device may be a semaphore of a current value of the switching value acquired during operation of the relay protection device. Such as "channel experiments".
The soft pressing plate displacement data of the relay protection device can be semaphore of state change of a soft pressing plate collected in the operation of the relay protection device. For example, "the press plate changes from throw-in to throw-out in the section of overflow 1".
The current state of the soft pressing plate of the relay protection device can be a semaphore of a current state value of the soft pressing plate collected in the operation of the relay protection device. For example, "over-flow 1 stage platen throw".
In one example, the existing transmission protocol IEC60870-5-103 can be expanded according to the relay protection data type, and the format of the corresponding operation data request message is configured. Taking the fault data as an example, the format of the operation data request message corresponding to the configuration fault data may be as follows:
Figure BDA0001838648870000081
the substation address, the retrieval data type, the starting time and the ending time in the format of the operation data request message are newly expanded fields, wherein the substation address refers to the address of the substation, and the two bytes are used for uniquely identifying the substation. And the retrieval data type is used for distinguishing the relay protection data type required to be requested. The starting time is used for indicating the starting time of the operation data request message which is required; the end time is used for indicating the end time that the operation data request message wants to request, namely the operation data request message wants to request the relay protection data between the start time and the end time.
For other fields, the transmission specification IEC60870-5-103 may be referred to, which is not described herein.
For other relay protection data types, the format of the corresponding operation data request message is configured, as long as the relay protection data to be requested can be clearly described, which is not limited in the present disclosure.
The data interaction between the relay protection information systems of different power grids can be realized by dividing the types of the relay protection data and pre-configuring the formats of the operation data request messages corresponding to the relay protection data types, and the formats of the operation data request messages are expanded on the basis of a transmission protocol IEC60870-5-103, so that the stability of data transmission between the relay protection information systems of different power grids is ensured.
As shown in fig. 3, in a possible implementation manner, the step S11 may include:
and step S111, acquiring the retrieval data type in the operation data request instruction.
And step S112, acquiring the format of the operation data request message matched with the retrieval data type.
Step S113, according to the operation data request instruction, filling the content in the format of the operation data request message, and generating the operation data request message.
And step S114, sending the operation data request message to a second relay protection information system.
In an example, the pre-configured format of the operation data request message corresponding to the relay protection data type may be stored in the first relay protection information system, for example, in a database, and used for being invoked when the operation data request message is generated.
The first communication device of the first relay protection information system receives the operation data request instruction and can analyze the retrieval data type requested by the operation data request instruction. The first communication device may search the stored format of the operation data request message according to the retrieval data type, and obtain the format of the operation data request message matching the retrieval data type, for example, the retrieval data type is fault data, and may search the database according to the fault data, and obtain the format of the operation data request message matching the fault data.
Taking the format of the operation data request message corresponding to the configured fault data as an example, the ASDU address, the substation address, the start time, and the end time in the operation data request message format corresponding to the fault data can be completely filled according to the time period (start time and end time) requested in the operation data request instruction, the requested substation address, the address of the relay protection device, and the like, and after the completion of the filling, the operation data request message of the fault data can be generated, and the operation data request message can be sent to the second relay protection information system to request the fault data from the second relay protection information system.
In a possible implementation manner, the format of the operation data file of the second relay protection information system may be a self-description file format, for example, an XML format. The operation data file may include relay protection data description information.
Because the types of the relay protection data are more and cannot be described uniformly, the operation data file can be selected to correspond to the types of the relay protection data, and by taking the types of the relay protection data as an example, the operation data file corresponding to fault data, relay protection device action data, relay protection device setting values, relay protection device event data, relay protection device alarm data, relay protection device switching value variation bit data, relay protection device switching value current state, relay protection device soft pressing plate displacement data and relay protection device soft pressing plate current state can be set.
In one example, each type of relay protection data can be abstractly described and decomposed into a structure of attributes and values, and each attribute is used as a label by using the capability of a self-description file format, so that the self-description of each type of operation data file is realized. Taking the self-description file format as an XML format and the relay protection data type as fault data as an example, the relay protection data description information included in the operation data file of the fault data may be:
Figure BDA0001838648870000101
Figure BDA0001838648870000111
the above is merely an example of the relay protection data description information included in the operation data file of the fault data, and the disclosure is not limited thereto.
For the relay protection data description information included in the operation data file corresponding to other relay protection data types, the relay protection data description information may describe the clearly corresponding relay protection data, and the disclosure does not limit this.
By configuring corresponding operation data files for different relay protection data types and utilizing the capability of extracting data attributes from the description files, data interaction between relay protection information systems of different power grids can cover various relay protection data, and an operation data response message can be generated as long as the operation data files are filled, so that integration of the relay protection data is more efficient, and the timeliness of the data interaction between the relay protection information systems of different power grids is further improved.
Fig. 4 shows a flowchart of a relay protection data transmission method between relay protection information systems according to an embodiment of the present disclosure. The method can be applied to a second relay protection information system, which can be a relay protection information system responding to an operation data request message (providing relay protection data). As shown in fig. 1, the method may include:
step S21, receiving an operation data request message sent by a first relay protection information system; the operation data request message comprises a retrieval data type.
Step S22, according to the retrieval data type, sending an operation data response message to a first relay protection information system; the operation data response message comprises an operation data file of the second relay protection information system.
As shown in fig. 2, the second relay protection information system may include a second communication device, the second communication device of the second relay protection information system may receive the operation data request packet sent by the first relay protection information system and forward the operation data request packet to the application device, the application device may analyze the retrieval data type included in the operation data request packet, may summarize the relay protection data matching the retrieval data type, and may transmit the summarized relay protection data matching the retrieval data type to the second communication device in a file form, and the second communication device may generate an operation data response packet from an operation data file matching the retrieval data type, for example, include the operation data file in the operation data response packet. The format of the operation data response message is not limited in the present disclosure.
The second communication device may send the operation data response message to the first relay protection information system.

In a possible implementation manner, the format of the operation data file of the second relay protection information system may be a self-description file format, and the operation data file includes relay protection data description information.
Fig. 5 shows a flowchart of step S22 according to an embodiment of the present disclosure. As shown in fig. 5, in one possible implementation, step S22 may include:
and step S221, acquiring an operation data file matched with the retrieval data type and relay protection data matched with the retrieval data type according to the retrieval data type in the operation data request message.
The application device of the second relay protection information system can search a database according to the retrieval data type in the operation data request message, and obtain an operation data file matched with the retrieval data type.
