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

Embodiment 1

[0034] This embodiment provides a 10kV distribution line demarcation switch setting management method, such as figure 1 shown, including the following steps:

[0035] S1: Obtain the parameters of the boundary switch equipment, and send the parameters of the boundary switch equipment to the management system. The equipment operation department completes the maintenance and management of the boundary switch equipment parameters, and designs a unified interface to input the boundary switch equipment parameters into the management system.

[0036] S2: The management system sets the boundary switch setting value of each boundary switch according to the setting principle and the parameters of each boundary switch device. The setting principle is to set the definite value of the demarcation switch according to the relevant regulations issued by the superior, according to the parameters of each demarcation switch equipment, and under the premise of satisfying the reliability and sens...

Embodiment 2

[0045] This embodiment provides a 10kV distribution line boundary switch setting management system, such as image 3 shown, including:

[0046] The parameter acquiring module is used to acquire the parameters of the boundary switch equipment, and send the parameters of the boundary switch equipment to the management system. The equipment operation department completes the maintenance and management of the boundary switch equipment parameters, and designs a unified interface to input the boundary switch equipment parameters into the management system.

[0047] The setting principle management module is used for the management system to set the boundary switch setting value of each boundary switch according to the setting principle and the parameters of each boundary switch equipment. The setting principle is to set the definite value of the demarcation switch according to the relevant regulations issued by the superior, according to the parameters of each demarcation switch equi...

Abstract

The invention provides a setting management method and system of a dividing switch of a 10kv distribution line. According to the method, the obtained dividing switch equipment parameters are sent to the management system; dividing switch fixed values are set by the management system according to the setting principle and all the dividing switch equipment parameters; after the dividing switches of the required dividing switch fixed value are confirmed, the setting calculation of the required dividing switch can be completed and required dividing switch setting lists can be automatically generated by the management system with no need for manual calculation, so that the method is high in work efficiency and low in error rate, the workload of power grid protecting professional setting staff is greatly reduced, the reliability and the standard degree of the dividing switch setting lists and the management process are increased; the dividing switch setting lists confirmed to be correct are filed in the management system after dividing switch checking, so that the dividing switch setting lists can be conveniently unified and consulted by all departments in the power system, the maintenance and the share of the dividing switch setting list protecting information among the different departments are benefited; and the unified standard management of the whole power equipment is benefited.

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. Outgoing switch protection trip. If the nature of the fault is permanent and the reclosing of the substation is unsuccessful, an accident in the medium-voltage user community...
