Embodiment 1

[0021] This embodiment discloses a distribution network distributed self-healing system based on a split layered architecture. A set of split layered self-healing devices (also called "self-healing devices") installed in each power distribution room System") is a system that connects communication, information interaction and logic calculation to realize self-healing function. The split and layered self-healing device in the power distribution room is specifically composed of a self-healing common host and a branch sensing terminal. The self-healing common host communicates with the self-healing common host in the adjacent power distribution room to complete the self-healing logic calculation and For information transmission, the special optical fiber is used as the medium between the branch sensing terminal and the self-healing public host, and the proprietary protocol is used for point-to-point communication interaction to complete the information collection and function exec...

Embodiment 2

[0030] Based on the same purpose as the above-mentioned embodiments, this embodiment discloses a distribution network distributed self-healing device based on a split layered architecture, including:

[0031] A self-healing common host that directly collects the bus voltage, segment current, and segment switch in the power distribution room;

[0032] Sensing terminals located at the intervals of each branch to transmit the current to the self-healing public host in real time with SV messages, and transmit the switch, switch, ground knife, and chain information to the self-healing public host through GOOSE messages host, and perform corresponding operations according to the control instructions of the self-healing public host; the branch interval includes the incoming and outgoing line interval and the feeder interval;

[0033] Each of the self-healing public hosts is connected to the self-healing public hosts of two adjacent power distribution stations with two pairs of optica...

Abstract

The invention relates to the technical field of electric power system relay protection, and discloses a distribution network distributed self-healing system and device based on a split layered architecture, so as to reduce the workload and cost of construction, debugging, and operation and maintenance. The system includes: a self-healing subsystem configured with a split layered structure based on a single power distribution room, each of which includes branch intervals and self-healing common hosts; There is a sensing terminal to transmit the current to the self-healing public host in real time with SV messages, and transmit the switch, switch, ground knife, and chain information to the self-healing public host through GOOSE messages, and according to the self-healing public host The control commands execute the corresponding operations; each of the public hosts is healed, and two pairs of optical fibers are connected to the self-healing public hosts of two adjacent power distribution stations to achieve peer-to-peer communication, and the summary of the automation related to the self-healing protection of the power distribution room The information is uploaded to the dispatch system.

Description

technical field [0001] The invention relates to the technical field of electric power system relay protection, in particular to a distribution network distributed self-healing system and device based on a split layered architecture. Background technique [0002] How to continuously meet the power demand of large cities that continue to increase is an important topic for power supply companies. The construction of large-scale urban distribution networks at home and abroad emphasizes safe and reliable power supply, and the reliability of power supply is a key indicator that reflects the level of distribution network construction and operation management. Compared with the centralized self-healing control system, the intelligent distributed power distribution self-healing control system can quickly locate, isolate and recover distribution network faults without human intervention, minimize or avoid power supply interruptions for users, and greatly The reliability of power supp...
