Embodiment 1

[0024] The feeder topology decentralized configuration method based on the switch adjacency relationship in the present invention is specifically: define the topology information dispersedly stored with the switch / switch group covered by each power distribution terminal as the basic unit as the topology slice information, and the topology information adopts The switch adjacency relationship expressed in the adjacency IP mode is configured. The line nodes, bus nodes, power supply nodes and load nodes in the topology structure are automatically generated through configuration information as implicit information. The topology information of the entire or part of the feeder is synthesized from the topological slice information of the electrical terminal.

[0025] Wherein, the topology piece information includes topology piece type, switch type and switch adjacency relationship; as figure 1 As shown, the topology slice type is divided into single switch ( figure 1 a), the same bus...

Abstract

The invention relates to the field of intelligent distributed feeder automation, in particular to a switch adjacency relationship-based disperse configuration method of a feeder topology. The method specifically comprises the steps as follows: dispersedly stored topology information employing a switch/switch group covered by each power distribution terminal as a basic unit is defined as topology piece information; the topology piece information is configured by a switch adjacency relationship represented by an adjacency IP mode; a line node, a bus node, a power supply node and a load node in a topological structure are automatically generated as implicit information through configuration information; and an intelligent distributed feeder automation system synthesizes required topology information of an overall or partial feeder by collecting the topology piece information which is dispersedly stored on each power distribution terminal through peer-to-peer communication. Building of the topological structure is achieved through information interaction between the power distribution terminals; the switch adjacency relationship-based disperse configuration method of the feeder topology has the advantages of high maintenance efficiency, a high collection speed and a small involved range; and a foundation is laid for automatic generation of a power supply recovery scheme of the intelligent distributed feeder automation system of a multi-contact power distribution network.

Description

technical field [0001] The invention relates to the field of intelligent distributed feeder automation, in particular to a feeder topology decentralized configuration method based on switch adjacency relationship. Background technique [0002] The fault recovery problem of intelligent distributed feeder automation refers to that after a power outage occurs in the distribution network, the distribution terminal realizes fault location and fault isolation independently of the main power distribution station through peer-to-peer communication, and independently realizes the recovery of non-fault outage areas. Power restored. When multiple contact switches cooperate to restore power supply, in order to avoid overload due to uneven load distribution, and to ensure that each power supply point has sufficient reserve capacity when the system fails again, when the power supply is restored after the distribution network fails, The principle of load balancing must be fully considered...
