Abstract

The invention discloses a composite grid structure with reliable power supply, and relates to the technical field of power distribution network grid structures and power distribution automation. The structure comprises a backbone network, a branch network and a power distribution switch monitoring terminal which are connected with one another, the backbone network is a double-petal type backbone network; the branch line network is a double-loop network which is composed of four power distribution rooms and comprises two branch loops. The number of the first-stage power distribution rooms in the four power distribution rooms is two; the number of the secondary power distribution rooms is two, the two branch loops are the same in structure and are respectively a first branch loop and a second branch loop, end points of the two branch loops at the side of each primary power distribution room are correspondingly connected with two sections of buses of one switching station in the backbonenetwork in a one-to-one correspondence manner, and the two secondary power distribution rooms are connected through a connection cable and operate in an open-loop manner; the power supply reliabilityof the distribution network is improved through the double-petal backbone network, the branch network of the double-loop network, the distribution switch monitoring terminal and the like.

Description

technical field [0001] The invention relates to the technical field of distribution network grid structure and distribution automation, in particular to a composite grid structure for reliable power supply. Background technique [0002] At present, the grid structure of the distribution network is various and the scale is getting larger and larger, but its performance and reliability need to be improved. [0003] Existing technical problems and thinking: [0004] How to solve the technical problem of improving the power supply reliability of the distribution network. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a composite grid structure with reliable power supply, which improves the reliability of the distribution network through the double-petal backbone network, the branch network of the double-ring network, and the monitoring terminal of the distribution switch. [0006] In order to solve the above-menti...
