Embodiment Construction

[0026] Please check figure 1 with figure 2 , a distribution terminal defect diagnosis system, based on the DMS system 10 of the distribution network automation master station, the DMS system 10 can collect terminal 11 operating data and is an existing system, the diagnosis system 20 includes a system database 21, a data import module 22. Index calculation module 23 and intelligent analysis module 24; establish the defect measurement index of the power distribution terminal and set the standard value of the defect measurement index of the power distribution terminal; the data import module 22 is connected to the DMS system 10 by signal, so as to import the terminal 11. The operation data is stored in the system database 21. The index calculation module calls the terminal operation data of the system database 21 and calculates the actual value of the defect measurement index of the distribution network terminal, and checks whether the actual value exceeds the standard through t...

Abstract

The invention discloses a power distribution terminal defect diagnostic system and a power distribution terminal defect diagnostic method. A power distribution terminal defect measurement index is established, a measurement index standard value is set, and the power distribution terminal defect diagnostic system is established based on an existing DMS (Database Management System). The diagnostic system comprises a system database, a data importing module, an index calculation module and an intelligent analysis module, real-time data of the terminal is imported from the DMS through a data module and is stored in the system database, the index calculation module calls the data in the system database and calculates the actual value of the defect measurement index of the power distribution terminal according to the set time period, the intelligent analysis module inspects that whether the actual value exceeds the range of the standard value or not according to the actual value, so as to diagnose a suspicious defect terminal, form a defect terminal set, realize automatic monitoring of the power distribution terminal defects, reduce labor force for manual inspection, improve the management efficiency of the power distribution system and shorten the terminal defect eliminating period.

Description

technical field [0001] The invention relates to a system and method for diagnosing defects of a power distribution terminal. Background technique [0002] At present, the operation and maintenance management of power distribution terminals in China basically stays in the fault defect repair process after dispatchers or automation personnel find fault defects during use or inspection. This primary stage operation and maintenance mode is facing the current increasingly Complex power grids, especially the extremely large number of power distribution terminals, have the problems of heavy workload, low efficiency and long time consumption. Contents of the invention [0003] The invention provides a defect diagnosis system and method for a power distribution terminal, which overcomes the problems of heavy inspection workload, low efficiency and long time for eliminating defects in the background technology. [0004] One of the adopted technical schemes that the present inventio...
