Problems solved by technology
The monitoring system database needs to convert the four-remote signal into a format conforming to the 61850 communication format and then communicate with the secondary equipment according to the four-remote storage point table. The debugging level of engineering personnel is high; since the monitoring point table has no direct mapping relationship with the SCD, when the monitoring point table changes, the SCD and the device CID cannot be updated synchronously in time, which brings hidden dangers to the management of the data source version

specific Embodiment
[0037] Specific embodiment: take the generation and synchronization of a substation monitoring system point table as an example, the process is as follows: first generate a file named "test station.
[0038]Analyze the SCD file through the substation configuration language SCL, analyze the communication description part, and obtain the device name and device IP; analyze the substation description part, and obtain the primary equipment information such as voltage level, interval, switch switch, etc.; analysis The electronic device (IED) description part obtains secondary device information such as logical node LN and data basic attributes; parses the data type template class (DataTypeTemplate) part to obtain the basic attributes of all data units under the LN.
[0039] According to the 61850 data attribute path, associated data attribute path, attribute type, attribute length, and the domains of the primary equipment table, measurement table, logical node information table and p...

The invention discloses an SCD-based substation monitoring system data point table generation and synchronization method. The invention belongs to the field of power system automation. The method comprises the following specific steps: 1, a full-station SCD file is generated; 2, relation information is obtained and mapped to a monitoring system relation database, the monitoring system creates a real-time database according to the relation database, and a monitoring system data point table is generated by the real-time database; 3, the system configuration tool updates a real-time database of the monitoring system according to the change content, and automatically and synchronously updates the content related to the same change in the SCD file; 4, finally, CRC check is carried out on the CID file exported by the SCD to ensure version consistency. According to the method, data homology, one change and global synchronization are realized, SCD analysis, monitoring point table generation, SCD file synchronization and CID file consistency verification are completed in an automatic mode, the reliability of SCD file version management and control is improved, and the engineering debuggingefficiency of a transformer substation is effectively improved.
Description
technical field [0001] The invention belongs to the field of electric power system automation, in particular to the field of substation automation monitoring system, in particular to an SCD-based method for generating and synchronizing data point tables of the substation monitoring system. Background technique [0002] With the continuous development of substation automation technology, the SCD (Substation Configuration Description) model based on IEC 61850 is widely used in smart substations to describe the system configuration of the whole substation. Among them, the IEC61850 standard defines a set of object-oriented service description system, which describes the object language and modeling of the data, equipment, and data structure of the substation hierarchical organization. Due to the large differences in the storage format and data model construction of the substation monitoring system database and the SCD model file based on IEC61850, it is difficult to directly map...
