Problems solved by technology

[0005] For this reason, the technical problem to be solved by the present invention is that in the prior art, the demarcation switch adopts manual management and manual calculation in the demarcation switch definite value calculation and demarcation switch definite value list generation process, which has low work efficiency and high error rate , the demarcation switch definite value list is archived in paper documents, which is very inconvenient for statistical review, and is not conducive to the maintenance and sharing of demarcation switch definite value single protection information between different departments, thus a 10kV distribution line demarcation is proposed Switch setting management method and system

Abstract

The invention provides a management method and system for a boundary switch constant value of a 10kV distribution circuit. The method comprises the following steps: sending acquired device parameters of a boundary switch to a management system; setting the boundary switch constant value through the management system according to the setting principle and the device parameters of each boundary switch; determining the boundary switch of the required boundary switch constant value; calculating the required constant value of the boundary switch. According to the method and system, a list of required boundary switch constant values can be automatically generated through the management system without manual operation, so that the working efficiency is raised, the error rate is reduced, the workload of a special setting worker for power grid protection is greatly decreased, and the reliability and standardization of the boundary switch constant value list and the management process are improved; after the review of the boundary switch, the correct and confirmed boundary switch constant value list is filed through the management system, thus each department of a power system can count and access conveniently, the maintenance sharing of the protecting information of the boundary switch constant value list among different departments can be performed conveniently, and the unified standard management of the whole power grid device is realized.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a method and system for managing the fixed value of a boundary switch of a 10kV power distribution line. Background technique [0002] The rapid development of the national economy has greatly increased the social demand for electricity, the scale of the power grid has continued to expand, and the number of power grid equipment has increased. When a fault occurs inside the user connected to the 10kV distribution line T in the power grid, if the fault occurs in the incoming line section, or if the fault occurs inside the user incoming line switch but its protection action time limit does not cooperate with the protection of the substation outgoing line switch, it will cause substation failure. The outlet switch is protected from tripping. If the nature of the fault is permanent and the reclosing of the substation is unsuccessful, an accident in the medium-voltage u...
