A power distribution terminal operation and maintenance management system

Abstract

The invention relates to the field of electric power terminals, and especially relates to a power distribution terminal operation and maintenance management system. An existing distribution network communication network is used to realize operation and maintenance management of a distribution terminal. Through the utilization of a power distribution terminal management protocol, running state information of a power distribution terminal device and correlated analog quantity information are collected. According to a preset processing rule, processing is carried out on the device running states of different categories, and corresponding device state report forms are generated for device operation and maintenance personnel to carry out assessment on the states of the device in order that maintenance strategies can be determined. At the same time, as for distribution network reconstruction, capacity expansion and distribution terminal fixed value modification, etc., through the utilization of the distribution terminal operation and the maintenance management system, the operation and maintenance personnel can carry out fixed value setting on the power distribution terminal in the distance. On-site maintenance is avoided. The power distribution terminal operation and the maintenance management system are very time-saving and the practicality of a power distribution automation system can be raised.

Description

technical field [0001] The invention relates to the field of power terminals, in particular to a power distribution terminal operation and maintenance management system. Background technique [0002] As the number of power distribution equipment continues to increase, if the traditional "planned maintenance" and "in-place" maintenance are adopted for the operation status management and maintenance of power distribution equipment, the workload is huge and the effect is not obvious. If the operation failure of the distribution network equipment cannot be detected and eliminated in time, when a short circuit or ground fault occurs in the distribution network, the relevant faults will not be isolated correctly, which will lead to the expansion of the power outage and reduce the reliability of the power supply.

Problems solved by technology

[0002] As the number of power distribution equipment continues to increase, if the traditional "planned maintenance" and "in-place" maintenance are adopted for the operation status management and maintenance of power distribution equipment, the workload is huge and the effect is not obvious

If the operation failure of the distribution network equipment cannot be detected and eliminated in time, when a short circuit or ground fault occurs in the distribution network, the relevant faults will not be isolated correctly, which will lead to the expansion of the power outage and reduce the reliability of the power supply

[0003] The traditional method adopts the special maintenance software of the terminal manufacturer to maintain the terminal on the spot, and adopts its own custom protocol for maintenance. The disadvantage is that the development language is different, and most of them are stand-alone software on the Windows platform, resulting in poor application effect. ; and the function is relatively single, it does not have the function of terminal operation status analysis and statistics, and does not have the function of intelligent early warning

There are also terminal manufacturers developing remote comprehensive maintenance systems for distribution networks. Although there has been great progress compared with dedicated maintenance software, the functions are still limited to traditional parameter maintenance, program upgrades, and equipment statistics, which are relatively simple, and the communication protocol with the terminals is still IEC60870 -5 series, it is easy to be confused with the business data of the main station, which brings certain risks to the stability of the system
