Abstract

The invention discloses a distribution network automatic monitoring method and system. The method includes: multiple monitoring networks are wirelessly connected to routers through APN communication dedicated lines, wherein the routers are connected to a distribution monitoring management platform; Measure the load current of each phase at each monitoring point on the overhead line of the distribution network, and upload the measurement results to the distribution monitoring and management platform; Determine the scale of the distributed power supply, and judge whether the distribution network is a microgrid according to the scale of the distributed power supply; Networking form: the power distribution monitoring and management platform accesses or controls each monitoring terminal of the distribution network. According to the distribution network automatic monitoring method proposed by the present invention, it can satisfy the reasonable scheduling of different distributed power sources, and improves the optimization scheduling efficiency.

Description

technical field [0001] The invention relates to the technical field of automatic power distribution, in particular to a distribution network automatic monitoring method and system. Background technique [0002] In addition to the substations in my country's distribution network, there is no current and voltage measuring device installed on the line, and the operating status of each line and the main transformer is unknown. Network operation mode, balanced line load, optimal line flow, prolonging the service life of equipment, have a very important impact on equipment life cycle management and other issues. [0003] In order to improve the power supply reliability of the power distribution system, the distribution network frame has begun to adopt a ring network structure. Under the ring network structure, it is difficult to set the protection value of the substation feeder line and the distribution network main line protection, which are mainly protected by overcurrent protect...
