Embodiment 1

[0063] In this embodiment, the distribution grid fault research and judgment platform is as follows: figure 1 As shown, it receives fault information from the existing 95598 system repair report, including fault information receiving module 1, fault equipment location module 2, fault information screening module 3, line topology analysis module 4, equipment operation information analysis module 5, line switch analysis Module 6, failure analysis display module 7;

[0064] The fault information receiving module 1 is used to receive and verify the fault information reported by the 95598 system;

[0065] The equipment positioning module 2 obtains the actual geographic location and account information of the source equipment related to the fault information through the existing power distribution production management system (PMS);

[0066] The fault information screening module 3 is used to screen the fault information after the equipment is located, and exclude the generated pla...

Embodiment 2

[0097] In this embodiment, the distribution grid fault research and judgment platform is as follows: image 3 What is shown is a change on the basis of Embodiment 1, except that it is the same as Embodiment 1 except that it receives fault information reported from the existing power consumption information collection system (CSM).

[0098] In this embodiment, the method for researching and judging the fault of the power grid is as follows: Figure 4 As shown, except that it is the same as the first embodiment, the difference is: (1) In step 2, since the unique code of the device already exists in the reported information, and there is no user number information to report, it is not necessary to obtain the information based on the user number For the low-voltage meter box or negative control device associated with the user, the distribution transformer, switch and negative control device are obtained as source equipment through the existing power distribution production managem...

Embodiment 3

[0100] In this embodiment, the distribution grid fault research and judgment platform is as follows: Figure 5 What is shown is a change based on the second embodiment, except that it is the same as the second embodiment except that it receives fault information reported from the existing distribution automation management system (DMS).

Abstract

The invention relates to a platform and a method for judging a fault of a match power grid and belongs to the technical field of power grid management. The platform comprises a fault information receiving module, a fault equipment positioning module, a fault information screening module, a line topological analysis module, an equipment operation information analysis module, a line switch analysis module and a fault analysis display module. The method comprises the following steps of: receiving fault information; acquiring source equipment information related to the fault information; screening the fault information to obtain a line topological structure and an equipment list; carrying out measurement analysis and judging whether equipment has a fault, executing the next step if yes, and finishing if no; detecting on-off information of a switch and judging whether a line fault exists; and determining the type, the position and the influence region of the fault and displaying the fault equipment and the information and the influence region thereof. According to the platform and the method, as soon as the reported fault information is received, the judgment can be automatically carried out in advance to obtain the accurate type, position and influence region of the fault so as to provide powerful basis for rush repair and management of the fault.

Description

technical field [0001] The invention relates to a platform and method capable of automatically researching and judging the location, type and scope of influence of a fault in a power distribution grid in advance as soon as the fault information is reported, and belongs to the technical field of power grid management. Background technique [0002] For a long time, when a fault occurs in the power distribution network, before entering the on-site emergency repair after the fault is reported, the fault information cannot be analyzed and the fault source and related equipment information can be accurately located. That is, the type of fault and the range of influence cannot be accurately judged in time. For example, the existing electric power users use the 95598 (State Grid Power Customer Service System) repair call of the power supply company to report for fault repairs, and the 95598 business acceptance personnel accept the repair reports, record the user repair information, ...
