Distribution network automation system

Abstract

A distribution network automation system comprises a power distribution main station, power distribution substations and power distribution terminals. The power distribution main station is responsible for monitoring and managing global information and used for monitoring and acquiring data of a whole distribution network to complete fault handling within the whole network; the power distribution substations are used for managing distribution station terminal monitoring equipment such as switchgear cubicles for loop networks, switching stations for distribution networks and the like, acquiring, gathering and uploading signals of the power distribution terminals to the power distribution main station, and transmitting orders of the power distribution main station to the power distribution terminals; the power distribution terminals mainly used for acquiring data of primary equipment, controlling switchgears, detecting and recognizing faults and sending fault information to the power distribution substations and the power distribution main station. The distribution network automation system has the advantages that power supply reliability can be greatly improved, fault time can be greatly shortened, voltage quality can be greatly improved to provide optimal voltage for users, and labor intensity can be relieved for operators; management level of the whole power distribution system can be improved, working efficiency is improved, and user service level is improved.

Description

Technical field [0001] The invention relates to a distribution management system, in particular to a distribution network automation system. Background technique [0002] With the rapid development of the national economy and the deepening of reform and opening up, power users have increasingly higher requirements for power quality and power supply reliability. Voltage fluctuations and short-term power outages will cause huge losses. Therefore, it is necessary to realize distribution automation in the distribution network in combination with grid transformation, so as to improve the management level of the distribution network and provide uninterrupted high-quality power for the majority of power users. [0003] Distribution automation is a concept put forward by western developed countries in the 1970s, and has been fully developed in Japan, Europe and the United States. There have also been many attempts in China, but mainly in cities. For distribution automation, the "Distribu...

AI Technical Summary

Problems solved by technology

At present, most distribution network automation systems can also monitor the operation status of the distribution network and change the operation mode remotely when the distribution network is operating normally, and can detect failures in time. However, most of the current distribution network automation systems Lack of automatic controls

Even if a small number of distribution network automation systems have automatic control functions, the system is too complex and redundant, which makes the cost high and is not suitable for popularization and application
