Problems solved by technology

However, the construction cost of the "3-1" ring network is also very high; the more complex the grid structure, the more difficult it is to operate and manage the line. Fault lines, the design of protection devices is also more complicated

Embodiment 1

[0027] exist Figure 4 Among them, the "four-circuit group" wiring structure includes four busbars, line tie switches, substation outlet switches and line section switches. Bus A and bus B are connected through tie switches K1 and K2, and bus C and bus D are connected. They are connected through tie switches K3 and K4, bus A and bus C are connected through tie switches K1 and K4, bus B and bus D are connected through tie switches K2 and K3; substation outlet switch KA and line section switch A1 Set in series on the connecting line between bus A and tie switch K1; substation outgoing switch KB and line section switch B1 are set in series on the connecting line between bus B and tie switch K2; substation outgoing switch KC and line section switch C1 are set in series On the connection line between bus C and tie switch K4; substation outlet switch KD and line section switch D1 are set in series on the connection line between bus D and tie switch K3; on the connection line between...

Embodiment 2

[0029] Take the connection line between tie switches K3 and K4 as an example, where two line segment switch positions are set in series, and the number of any line is not limited.

[0030] This wiring method can be extended to a "back" ring network, such as Figure 5 As shown, (1) Structural description: The wiring method can be an overhead line or a cable line for power supply. The line has four busbars for power supply. Generally, busbar A and busbar C come from the same substation, and busbar B and busbar D come from another substation. For particularly important loads, all four busbars can come from different substations to further improve the power supply of the line. power supply reliability. Such as figure 2 As shown, bus A and bus B are connected through tie switches K1 and K2, bus C and bus D are connected through tie switches K3 and K4, and bus A and bus C are connected through tie switches K1, K5, K8 and K4 Connection, bus B and bus D are connected through conta...

Abstract

The invention discloses a power distribution network connection wiring structure shaped like a Chinese character "hui". The structure mainly comprises the wiring mode that four "hui"-shaped structuresare connected into a group in an intersection way, "hui"-shaped wiring does not require additional assumption of reserve bus, each bus supplies power to the load under the normal situation, and the certain reserve capacity is only required to be reserved on the bus so that the construction cost can be greatly reduced, the number of the load transfer paths of the line is high and scheduling management is facilitated.

Description

technical field [0001] The invention relates to the technical field of distribution network wiring, in particular to a "back"-shaped connecting connection structure of a distribution network. Background technique [0002] The existing wiring methods of the distribution network often cannot satisfy the economical construction of the distribution network and the reliability of power supply at the same time. The wiring method of the distribution network with a relatively simple structure has low construction costs and the reliability of power supply is generally not high; the distribution network with a relatively complicated wiring method has high construction and maintenance costs, and the storage power equipment has not been fully utilized. , resulting in a waste of resources. [0003] Such as figure 1 As shown, the single radial connection is the most widely used in the distribution network. The distribution line of this connection method has only one incoming busbar. Its...
