Method and system for updating information of power distribution automation graph-model interaction point table
Technical Field
The invention relates to the field of distribution automation, in particular to a method and a system for updating information of a distribution automation graph-model interaction point table.
Background
In order to ensure that a regulation and control operator can accurately and comprehensively monitor real-time operation information of a power grid such as remote signaling and remote measuring of a power distribution station and implement safe and reliable remote control operation on monitoring equipment in the station after the power distribution terminal access work of a power distribution automation system is completed, a mode of carrying out point-by-point actual transmission on a power distribution terminal telecontrol information point table is generally adopted in the process of developing the power distribution terminal access system of each stage of the power distribution automation system so as to verify the working correctness of each link from a main station system to the power distribution terminal.
The GIS system is used as a source of graph model information of the distribution automation system, upgrading and reconstruction can be carried out according to the management requirements of a distribution network, the ID of the graph model after upgrading is different from that of the graph model in the distribution automation system, therefore, after a new graph model of the GIS system is introduced into a master station system, the incidence relation of an original graph model library is rebuilt, in the actual work, the graph model and the distribution equipment complete the work through the close incidence relation, because the line and the graph model are in one-to-one correspondence, when the line changes, the graph model can change along with the line, so that the incidence relation between the graph model and the distribution equipment changes, and the configuration and verification of the incidence relation between the new graph model and the distribution equipment are particularly important. Conventionally, for such a situation, all distribution stations already in operation need to be re-geared to ensure consistency of the drawing library, which results in a significant increase in workload for the relevant workers and also involves a large number of power outages, thereby risking quality service.
Therefore, it is necessary to provide a method and a system for updating the information of the distribution automation graph-model interaction point table, which can make full use of the original results of the operation management work of the distribution automation system, do not affect the normal operation of the system, do not need to transmit field devices one by one, and can accurately verify each 'three remote' point, thereby ensuring the smooth transition between the graph-model library in the new distribution automation system and the old distribution automation system.

Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
Example 1
Referring to fig. 1, the present embodiment provides a method for updating information of a distribution automation graph-model interaction point table, including the following steps:
copying data of the old distribution automation system to a new distribution automation system, and performing associated configuration on the new distribution automation system according to a new template;
the new distribution automation system and the old distribution automation system are connected into the same simulation terminal, and the simulation terminal, the new distribution automation system and the old distribution automation system carry out remote control, remote measurement and remote signaling data transmission;
monitoring remote control information, remote measurement information and remote signaling information transmitted between the simulation terminal and the new distribution automation system and between the simulation terminal and the old distribution automation system, verifying the correctness of all data transmitted by the new distribution automation system and the simulation terminal by taking all data transmitted by the old distribution automation system and the simulation terminal as a reference, and when the verification is wrong, positioning the wrong position and indicating a user to modify the new distribution automation system until the two are completely consistent.
Specifically, for example, when a certain in-service device is used, firstly, data of an old distribution automation system is copied to a new distribution automation system, then, a new graph model of the GIS system is imported into the new distribution automation system, and the new distribution automation system re-associates and configures the distribution devices in the library according to the new graph model of the GIS system. And then, the old distribution automation system and the new distribution automation system are accessed into the same simulation terminal.
Specifically, telemetering simulation test data and remote signaling simulation test data of the same point are sent to a new distribution automation system and an old distribution automation system through a simulation terminal, wherein the telemetering simulation test data covers all remote measuring points in a system station, and the remote signaling simulation test data covers all remote signaling points in the system station. Then, a remote measuring point table and a section information table thereof, a remote signaling point table and an alarm event data table are derived from a dispatcher interface of the new distribution automation system, and all the derived information and data are processed into a file in a standard format to be compared by an event processing module of the new distribution automation system according to the standard and the requirement of transmission comparison, preferably, the file is in a format of 'CSV', and the file comprises all the remote measuring information and the remote signaling information which need to be verified and are contained in the new distribution automation system. And exporting the files in the standard format to be compared of the old power distribution automation in the same way.
Further, the data comparison module acquires the files in the standard format to be compared in the new distribution automation system and the files in the standard format to be compared in the old distribution automation system through the telecontrol channel, and presents all the information contained in the files in the standard formats of the two parties in a visual interface according to the order of the point numbers of the information contained in the files in the standard formats of the two parties. It should be noted that the telecontrol channel is a communication channel connecting the new distribution automation system and the simulation terminal, and the old distribution automation system and the simulation terminal.
And then, the data comparison module automatically judges the correctness of the information of the new distribution automation system by taking the information of the old distribution automation system presented in the visual interface as a reference, specifically, the verified information content comprises a telemetering point number, a telemetering coefficient, a telemetering description, a telemetering point number, a telemetering description and a telemetering alarm type, if an error occurs, the data comparison module gives an error prompt on the visual interface, locates an error point, and then instructs a user to correct the error point so as to ensure that the telemetering information of the new distribution automation system is completely consistent with the telemetering information and the telemetering information of the old distribution automation system, and generates detailed comparison information into logs in an EXCEL form for storage after all information is compared and compared.
In addition, before comparing the new distribution automation system with the old distribution automation system, the respective remote control sequence is confirmed, then the respective remote control sequence operation table is edited and printed out, and the remote control instruction is issued to the corresponding control point of the simulation terminal in the respective remote control interface according to the sequence of the respective remote control sequence operation table, and the message monitoring module in the data comparison function module monitors and records the remote control instruction of the new distribution automation system and the old distribution automation system through the switch mirror interface.
And then the message monitoring module sends the result to the message analysis module, the message analysis module stores the remote control instruction, the remote control instruction is analyzed to obtain specific message data, the specific message data is analyzed into a plaintext event, the specific information of the two parties is compared by the data comparison module, the comparison result is displayed in a visual interface, and when the comparison result is wrong, a user can correct the error point in the new distribution automation system according to the comparison result so as to ensure that the remote control information of the new distribution automation system is completely consistent with the remote control information of the old distribution automation system.
It should be noted that when the above-mentioned remote measurement information, remote signaling information, and remote control information, that is, "three remote" information comparison is performed, the normal operation of the old distribution automation system is not affected, and the manpower and material resources in the actual operation are saved.
Further, the staff selects the spare interval to check the information of the power transmission and distribution terminal on site. Specifically, the spare intervals are controlled by remote signals at the power distribution terminals. Alternatively, the standby interval on-board power distribution terminal information may also be controlled by an on-site signal. It should be noted that the remote signal refers to a command for controlling the standby interval, which is sent by the new distribution terminal and the old distribution terminal; in-situ signaling refers to the operation of a spare interval by a worker at the on-site distribution equipment. It is worth pointing out that in practical cases the standby interval is a standby switch that is already set up in relation to the user but is not wired to the user, so controlling the standby interval does not affect the normal user supply.
And after the 'three remote' information in the new distribution automation system is completely consistent with the 'three remote' information in the old distribution automation system, switching the front channel of the old distribution automation system to the new distribution automation system to complete the updating of the graph-model interaction point table information.
