Embodiment Construction

[0058] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0059] The invention provides a distribution network fault processing method based on distributed intelligence, which mainly includes establishing a power supply restoration target suitable for distributed feeder automation; establishing a regional load evaluation model in combination with the magnitude of the load current and the importance of the load; setting an agent For the terminal, the depth-first traversal algorithm is used to establish the topology model of the area to be restored; a power supply restoration scheme based on distributed intelligence is proposed, including four parts: a single-connection switch power supply restoration scheme and a single-connection load shedding power supply restoration scheme. For its system frame,...

Abstract

The invention discloses a distribution network fault processing method and device based on distributed intelligence. The method comprises the steps of establishing a power restoration target applicable to a distributed feeder automation system by combining operation characteristics of the distributed feeder automation system; establishing a regional load evaluation model in consideration of the quantity of loads and the importance degree of load types; and establishing a topology model of the region to be restored by adopting depth-first traversal, and performing fault processing based on a single interconnection switch power restoration method and a single interconnection switch load shedding power restoration method to realize power restoration. The method can reduce the pressure of centralized control and information processing of the master station and realize a lean power restoration strategy of the multi-connection, multi-branch and multi-power distribution network.

Description

technical field [0001] The invention relates to a distribution network fault processing method and device based on distributed intelligence, and belongs to the technical field of power systems and automation thereof. Background technique [0002] Self-healing control is one of the remarkable features of smart distribution network, and distributed feeder automation (FA) technology is an effective means to realize self-healing control of smart distribution network. Distributed FA technology is classified according to the decision-making method, and can be divided into cooperative distributed FA and proxy distributed FA. The former is suitable for power distribution lines with sufficient spare power reserve capacity and simple wiring, while the latter can be applied to multi-connection and multi-branch , Power distribution network with complex structure. Distributed FA technology can be classified into regional slow-acting distributed FA and neighborhood fast-acting distribute...
