Problems solved by technology

[0003] However, in the related technology, the monitoring of the operating status of the distribution station area mainly relies on the combination of power distribution terminals and electric meters, and it is impossible to achieve refined management. In particular, once a fault occurs in the line of the distribution station area, it cannot be accurately located. Failure to carry out emergency repairs in time, unable to guarantee the quality and reliability of power supply in the distribution station area

Embodiment 1

[0031] Example 1: Using mobile phone number as contact method

[0032] Extract the mobile phone number of the operation and maintenance personnel from the failure maintenance order, convert the editing of the failure maintenance order into a voice form of failure maintenance prompt information, dial the operation and maintenance personnel and broadcast the failure maintenance prompt information.

Embodiment 2

[0033] Example 2: Using mobile phone number as contact method

[0034] The mobile phone number of the operation and maintenance personnel is extracted from the failure maintenance order, the editing of the failure maintenance order is converted into the failure maintenance prompt message in the form of SMS, and the short message of the failure maintenance prompt information is sent to the operation maintenance personnel.

Embodiment 3

[0035] Example 3: Using email as contact method

[0036] Extract the email address of the operation and maintenance personnel from the failure maintenance order, convert the editing of the failure maintenance order into a failure maintenance prompt message in the form of an email, and send the failure maintenance prompt message to the mailbox of the operation and maintenance personnel.

[0037] The above three embodiments are only used to explain how to push fault maintenance prompt information to operation and maintenance personnel, rather than limiting the technical solution itself. The specific method of pushing fault maintenance prompt information can be adjusted according to design requirements.

[0038] Further, in order to track the progress of fault handling in time and realize closed-loop management, the method also includes: detecting whether the maintenance confirmation information sent by the operation and maintenance personnel is obtained, wherein the maintenance confirma...

Abstract

The invention discloses an operation state monitoring and fault control system for a low-voltage transformer district. The system comprises a plurality of line monitoring units which are used for acquiring the operating parameters of a line end meter box and a branch box, a topology information acquiring unit which is used for obtaining the topological structure information of the low-voltage transformer district, a processing unit which is used for detecting whether a line and equipment in the low-voltage transformer district are failed or not based on the obtained operating parameters and topological structure information and generating a fault repair list when a fault is determined, and a pushing unit which is used for pushing the fault repair prompt information to maintenance personnelbased on the fault repair list. Through the technical solution of the invention, the fine monitoring of the operating state of the low-voltage transformer district is realized, the fault is timely predicted and repaired, the fault response speed is improved, and the power supply quality and power supply reliability of the power distribution transformer district are ensured.

Description

Technical field [0001] The present invention relates to the technical field of power distribution, in particular to a low-voltage power distribution station area operating state monitoring and fault management and control system. Background technique [0002] The distribution station area serves as a single distribution transformer to the user's power supply area to realize electric energy distribution, continue to provide electricity to users, and ensure the normal use of electricity in an area. With the increase of various electrical equipment in life and work, the overall demand for electricity is also increasing, which undoubtedly increases the load on the distribution station area, which will inevitably appear under heavy load pressure or other factors. Faults, such as short circuits, leakages or equipment failures in the distribution station area, directly affect the power supply quality and reliability of the distribution station area. Therefore, it is particularly importa...
