Embodiment Construction

[0015] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0016] A method for changing the master station number based on the frequent change of the distribution automation station number, such as figure 1 shown, including the following steps:

[0017] Step 1. Check the front-end remote signaling definition table to determine whether there is data in the front-end remote signaling definition table of the master station. If there is no data, it means that the station has not been modified and no data maintenance is required; After modification, go to step 2;

[0018] Step 2. After confirming that the main station has been transformed, check whether the data information in the pre-remote signal definition table contains the substation information. If it contains the substation information, enter the SCADA / external equipment / protection node table, delete redundant information, and Change the ID number of t...

Abstract

The present invention relates to a method for changing the number of a main station based on frequent changes of the station number of distribution automation. Its technical features include the following steps: Step 1. Check the pre-remote signal definition table to determine the pre-remote signal definition table of the master station Whether there is data in; Step 2. After confirming that the main station has been transformed, check whether the data information in the pre-remote signal definition table contains the sub-station information; Step 3. Replace the original station number in the protection name with the new station number; Step 4. Change the name of the switch, change the combined device domain to the new refresh station number modified in the SCADA / outside equipment / switch station table in step 2, and change the feeder domain to which it belongs according to the layout of the distribution network; step 5, enter fes / channel table and fes / Distribution network communication terminal table, change the channel name and terminal name according to the new refresh station number. The invention can ensure that the system accurately presents various information to the dispatching staff, helping them to accurately analyze the state of the power grid.

Description

technical field [0001] The invention belongs to the technical field of power distribution automation, and relates to a method for changing the number of a main station of power distribution automation, in particular to a method for changing the number of a main station based on frequent changes of station numbers of power distribution automation. Background technique [0002] Distribution automation has entered the stage of in-depth practical application, and the deployment of graphics, models, and DA strategies have been completed and entered a mature stage. However, due to the particularity of the distribution network, some terminals have been switched to other lines, and in order to standardize management, Its station number needs to be changed. For the station terminal, it is sufficient to refresh the number. But for the distribution automation system of the main station, changing a terminal is not only to change its name on the graph, but also involves model data. , cha...
