Embodiment

[0018] The topology analysis method used for the detection of residential power distribution lines, the following steps are performed in sequence:

[0019] A. Establish a model of the distribution network structure in the database, which includes line voltage, current, switch, line, and load data;

[0020] B. Input the initial state data of the model when the model is established;

[0021] C. The process of topology analysis, comparing and analyzing the data in the real-time data database;

[0022] D. When the change between the data in the power grid and the data collected last time exceeds the set value, the system will search for a corresponding processing plan from the database.

[0023] Wherein, the switches, lines and loads in step A are connected through nodes.

[0024] The processing solution in step D includes: displaying the location of the fault point in the line, listing the name of the line switch that needs to be opened and the name of the tie switch that needs...

Abstract

The invention discloses a topology analysis method for community distribution line detection, which successively comprises the following steps: establishing a model of a distribution network structurein a database, wherein the model includes a line voltage, a current, a switch, a line, and load data; inputting the initial state data of the model during the establishment; in the process of topology analysis, comparing and analyzing the data in a real-time data database; when a change of the data in a power grid relative to the data acquired last time exceeds a set value, searching for, by a system, a corresponding solution in the database. The method solves the lack of automatic processing when replacing remote distribution control by local distribution control in the prior art. When used,the topology analysis method for community distribution line detection provides an automatic topology analysis method during local distribution control, and provides the optimal solution when a faultoccurs, thereby increasing the response speed and finding and processing the faults in time.

Description

technical field [0001] The invention relates to community power distribution, in particular to a topology analysis method for detecting community power distribution lines. Background technique [0002] With the introduction of the smart grid concept, advanced power distribution technology and user-side requirements are gradually being paid attention to. Remote control has good flexibility because it provides a visual interface for the staff and combines automatic control and manual intervention during fault handling. However, the existing remote power distribution control method has a slow response speed and does not handle faults in time. Contents of the invention [0003] The present invention solves the problem of lack of automatic processing when local power distribution control is used to replace remote power distribution control in the prior art, and provides a topology analysis method for community power distribution line detection, which provides automation when lo...
