The current dispatching master station browses substation-side data, and uses a power system remote browsing technology and conventional communication protocols (such as IEC101, IEC104, DISA and the like) to browse the data. The remote browsing technology of the power system does not use model data modeling at the station end, but relies on a graph G file of a browsed picture in a man-machine window, and meanwhile, picture data refreshing relies on a data mapping relation described in the G file. The definition of the browsing data is different from that of the remote control model used by the monitoring system in the transformer substation, and the data browsing use definition of the same measuring point information in different pictures is different. The definition of the same measuring point model in the station-side telecontrol model is unique, and the station-side needs to independently maintain a remote browsing model of the power system so as to store the association relation between the measuring point in the graph G file and the model in the monitoring system in the transformer substation. Because of the complex many-to-one relationship, when the functions of remote control, historical data query and the like are realized, the safety risk of operation is increased, and the complexity of the system and the workload of personnel maintenance are increased. When the conventional communication protocol is used for data browsing, the definition modeling is needed to be performed by referring to the station end model data, the graph and model information association is performed, the data point table, the protocol parameters and the like are agreed, and as the information sharing complexity caused by the deviation of understanding of different manufacturers on the same protocol and the difference of implementation details is high, the difference of station modeling information standards and the acceptance of substation information depend on transmission experiments, the station operation period is prolonged, and the working strength of operation and maintenance staff is increased.

Detailed Description
The invention will be further described with reference to specific examples.
The man-machine browsing window comprises a plurality of devices in the browsing picture content, each device manages a plurality of report control blocks, and each report control block is associated with from a few to hundreds of measuring points contained in the data set. The data displayed in the main station man-machine window browsing picture is the result of screening and matching from the TCP connection between 1 main station and a sub station, usually part of measuring points in the report control blocks under jurisdiction in a plurality of different devices, when the data browsing is carried out according to DL/T860 report service, all data in the current report control blocks are required to be transmitted, so that the browsing data of one browsing picture is a small amount of information (hundreds) selected from tens of thousands of measuring points, the transmission bandwidths of the sub station and the main station are occupied in a large amount, and the sub station transmits a large amount of useless measuring point information. With the increase of the number of devices contained in the human-computer window browsing screen of the master station, the more report control blocks are used, the more and more redundant information irrelevant to the current human-computer window data browsing is transmitted, and therefore, difficulties are brought to operation and maintenance work.
As shown in fig. 1-2, a DLT 860-based real-time data browsing method includes the steps of:
As shown in FIG. 3, in step 1, a centralized control master station man-machine builds a real-time data browsing model based on the SCD file and stores the model in a relational database. Analyzing the substation SCD file, completing model extraction of primary equipment and non-equipment quantity (such as protection information) used by a master station man-machine according to equipment asset numbers (namely object IDs) according to SCD model specifications, and unifying and correlating the primary equipment and the non-equipment quantity used in data interaction of the master station and the substation on the basis of IEC61970 and IEC61850 standards.
The primary station adopts the primary device and non-device quantity of the substation to select the measuring points, and uses reference description for the primary device and non-device quantity of the data interaction of the primary station and the substation. And storing the inclusion relation between the measuring points and the data set and the sequence of the measuring points under the jurisdiction of the measuring points and the data set.
The inclusion relationship between the measuring points and the data set is divided into 2 types: "telemetry station ID- > reference description", the stations are associated with reference descriptions in the dataset by station ID. The sequence of the measuring points and the measuring points governed by the data set is as follows: "reference description- > data set name and data set sub-sequence number", the measurement points are associated with the data set name and the data set sub-sequence number through the reference description, and because the "report service" in the IEC61850 standard is used when data interaction is performed based on DL/T860, the master station needs to store the association relationship between the "data set" and the "report control block" at the same time: "data set name- > report control block name", the data set associated with the master station measurement point is associated with the name of the substation report control block by the data set name, - > means. By the method, the real-time data browsing model construction of the master station and the substations is completed.
As shown in fig. 6, the association between the "data set" and the "report control block" is stored, and as shown in fig. 7, the association between the measurement point and the data set is stored.
When data interaction is based on IEC61850 standard, the reference description is contained in a data set as a unique expression of actual measurement information such as primary equipment and non-equipment quantity; and the model construction mode based on the IEC61970 standard has no characteristic values of data set and reference description. Therefore, the master station realizes the model association matching between IEC61970 and IEC61850 standards by increasing the reference description of the primary equipment and the non-equipment quantity and the inclusion relation between the measuring points and the data set and the sequence of the measuring points under the jurisdiction of the data set.
And 2, adopting a dynamic data set created by using a DL/T860 data set service for the data of the browsed pictures in the master station man-machine. And creating a dynamic data set containing different measuring point numbers and types according to the man-machine browsing requirement of the master station, and carrying out data interaction through the substation.
As shown in fig. 5. Dynamic datasets are classified into telemetry and telemetry classes 2. The single measuring point data in each dynamic data set consists of reference description, sequence number, measuring value and measuring state. The sequence number is different from the sequence of the measuring points under the jurisdiction of the data set of the measuring points in the original device, and refers to the sequence of the measuring points in the current dynamic data set. If the data set sub-sequence number of a certain measuring point in the device is "1", the sequence number in the dynamic data set generated in the man-machine window is "5".
The description of the equipment in the SCD file is that a device (an intelligent terminal or a merging unit) is used as a data exchange unit, and a master station is that a substation is used as a data exchange unit, wherein a single substation contains equipment information of a plurality of devices. As shown in fig. 8, in conventional data browsing, all interaction data of the main station and the sub station originate from the same TCP socket, the data displayed in the man-machine window is a result of screening and matching from the TCP sockets between 1 main station and sub station, and only a small number of measurement points are selected from the transmitted tens of thousands of measurement points, so that the conventional method brings redundant data, so that the method is adopted to process measurement information related to the current man-machine window browsing picture, thereby improving monitoring intensity, optimizing data identification and reducing network bandwidth.
Step 3, creating a communication unit based on the TCP socket by using a single master station man-machine window:
(1) The master station communication management module is used for receiving 1 or more data requests of the master station man-machine, forwarding the data requests to the substations, and simultaneously receiving data responses of the substations and feeding the data responses back to the corresponding master station man-machine. Therefore, the man-machine window establishes TCP connection with the master station communication management module, and data needed in the dynamic data set of the real-time data browse of the man-machine window is sent to the master station communication management module at the corresponding position in the corresponding data set of the sub-station, the association relation between the dynamic data set and the corresponding report control block of the sub-station and the command of enabling the sub-station to report the control block.
As shown in fig. 4, (2) master station communication management module distinguishes dependencies from substation communication links: "machine name of single master station man-machine window", "browse picture name", "man-machine window number". The master station communication management module takes a single master station man-machine window as a communication unit, as shown in fig. 9, establishes TCP connection with the substation according to the machine name, the browse picture name, the man-machine window number, the IP address, the port and the association relation between the master station and the substation, informs the substation of preparing data required by a dynamic data set, associates the dynamic data set with a report control block, enables the report control block, performs data interaction required by the dynamic data set, and forms feedback data.
(3) The master station communication management module acquires feedback data of the substation from the established TCP connection with the substation, and returns the feedback data through the established TCP socket between the master station man-machine and the master station communication management module;
and 4, after receiving the feedback data, the master station man-machine finds the corresponding master station man-machine through the machine name where the single master station man-machine window is located by the reference description, the required data and the sequence number in the feedback data, finds the corresponding man-machine window through the man-machine window number, and finds the corresponding browsing picture through the browsing picture name for real-time browsing.
According to the invention, the current man-machine window is used as a communication unit, the TCP connection is created, the dynamic data set only comprising monitoring picture measuring points is generated, the interactive content is only related to data which is needed in urgent need of current picture monitoring, the data which are not on the picture in the original permanent data set are not transmitted, the measurement number in the TCP connection of the newly-built man-machine window is reduced from thousands to tens of thousands, and the data interaction is efficient and concise.
The foregoing is only a preferred embodiment of the invention, it being noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the invention.
