A 10kv Distribution Network Line Inverting Method

Abstract

The invention discloses a 10kV distribution network line reversing method, comprising the following steps: 1) collecting the characteristic parameters of each 10kV line in the 10kV distribution network in the jurisdiction, and establishing a database; 2) monitoring each 10kV line in the 10kV distribution network 10kV line operation status, when one of the 10kV line A triggers the switching condition, enter step 3) select the 10kV line B after switching; 3), first screen all 10kV lines that have a contact relationship with 10kV line A to meet the necessary Conditional 10kV lines; multiple 10kV lines that meet the necessary conditions are scored according to non-essential conditions, the sum of the scores is arranged from high to low, and the line with the highest score is selected as the 10kV line B after switching; 4), the 10kV Part / load on line A reversed to 10kV line B. The present invention effectively avoids the existing problem that a new line is generated after performing reverse operation through manual experience judgment.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a circuit reversing method for a 10kV distribution network. Background technique [0002] Grid mode change is a common adjustment measure, and it is widely used in fault handling and dealing with seasonal risks. Temporary adjustments are made by changing the reverse mode to ensure reliable operation of the grid. [0003] The change of the existing switching method only considers the interconnection between the same voltage levels, and does not fully consider the relationship with its superior power supply, relay protection, phase sequence, actual site conditions, etc., and the connection between each line The relationship requires artificial memory, and there are incomplete and inaccurate situations. Solving one problem often leads to the emergence of another causal problem. In order to solve the new problem, the method must be changed again, resulting in the ...

[0003] The change of the existing switching method only considers the interconnection between the same voltage levels, and does not fully consider the relationship with its superior power supply, relay protection, phase sequence, actual site conditions, etc., and the connection between each line The relationship requires artificial memory, and there are incomplete and inaccurate situations. Solving one problem often leads to the emergence of another causal problem. In order to solve the new problem, the method must be changed again, resulting in the workload of the on-duty and on-site operators. Increase, seriously increase the risk of power grid operation

Some on-site actual conditions cannot be obtained from the data and lack of comprehensive consideration during implementation. They can only be judged through actual on-site operations, and there is a lack of simulation to prevent misoperations before implementing changes.
