Description
Technical Field
The invention relates to a substation reconstruction and extension configuration consistency comparison and verification method based on RCD, and belongs to the technical field of intelligent substations.
Background
The intelligent substation monitoring system is the basis of scheduling control and operation production of an intelligent power grid, and the data communication network shutdown is used as a link for information interaction and cooperative control between main stations and plays an important role in the intelligent substation monitoring system.
An IEC61850 intelligent Substation Configuration Description (SCD) file is an important tool for reflecting system configuration information of an intelligent substation, and mainly aims at information such as a primary system structure, intelligent equipment and communication configuration thereof in the substation. At present, the analysis, verification and comparison management and control of an SCD file by an intelligent substation are completed, including the management of primary equipment, but some teletransmission services, including teleoperation, information protection and the like, exist in the intelligent substation, but are not managed and controlled, and the services are completed by a data communication network shutdown.
In an intelligent substation, a telemechanical configuration description file (RCD) file describes a platform-independent table of remote information points. Taking the telecontrol service as an example, the RCD file contains all information to be transmitted by the plant station, including contents such as basic information, version information, combined signal information, telemetering forwarding information, remote signaling forwarding information, remote control forwarding information, remote adjusting forwarding information, and the like, in units of channels. Due to the fact that the information content of the remote transmission information point table needs to be repeatedly modified and verified in the process of construction, debugging, operation and maintenance, transformation and extension of the intelligent substation, more remote transmission information point table versions can be formed.
In engineering, the change information of the versions needs to be known, and the change difference of each version can be intuitively obtained in a convenient and rapid comparison mode. In order to reduce maintenance workload and improve maintenance efficiency and operation safety and reliability of a transformer substation, the invention provides a transformation, extension and configuration consistency comparison and verification method based on RCD.
The method is suitable for a mode of carrying out communication point alignment between the main station and the sub station, and in the process of reconstruction and extension of the transformer substation, after the part of the newly added and replaced signals are replaced, the main station and the sub station can carry out manual point alignment on the newly added and replaced signals, but the method is limited in that the equipment which is already running can not be stopped, so that the communication test of the main station and the sub station can only be processed by changing the part. Therefore, two problems are caused, on one hand, the change of the traditional point table may affect the configured points and needs to be checked and removed, on the other hand, after the configuration modification is carried out on the in-station library, a certain influence may be caused on remote transmission, the traditional manual point-aligning mode only considers the correctness of the remote transmission point table and does not consider the corresponding relation whether the remote transmission point table is consistent with the in-station information or not, and the matching is carried out only through characters or names, so that the risk exists. The method adopts two machines, namely an SCD file based on IEC61850 and an RCD file of the current national grid network machine four-unification four-standard, to automatically generate the association relationship of the files and compare the association relationship with the machines, so that the problem of communication point omission in the reconstruction and extension project is avoided.

5.2.1 if the address exists, comparing the signal IEC61850 path name with the corresponding A.scd model file signal address character string, and checking whether the address exists;
5.2.1.1, if the signal point exists, the signal point is the signal point in the original equipment, and the next step 5.2.1.3 is carried out;
5.2.1.2 if the point does not exist, indicating that the point is a newly added equipment signal point or an original equipment newly added point, and turning to the next step 5.2.1.3;
5.2.1.3 comparing the number of signals not searched for matching, if RCD _2 signal points are the same as RCD _1, it is judged as covering modification, if RCD _2 signal points are more than RCD _1, it is judged as covering modification of RCD _1 non-matching upper point number of signals and adding RCD _ 2-RCD _1 non-matching upper point number of signals, otherwise, it is judged as covering modification of RCD _2 non-matching upper point number of signals and deleting RCD _ 1-RCD _2 non-matching upper point number of signals, finally classifying and coloring the non-searched matching lines and outputting the comparison result to the comparison analysis report;
5.2.2 if the signal does not exist, judging that the signal in the RCD _2 file is a deleted equipment signal point or an nonexistent signal, classifying and coloring the signal, and outputting a comparison result to a comparison analysis report;
5.2.3 alignment of all forwarding point table signals in turn.
