Abstract

The invention discloses a method for delaminating and districting of a 10 KV medium voltage distribution network. The 10 KV medium voltage distribution network comprises a plurality of transformer substations, a plurality of switching stations and a plurality of power distribution stations; each transformer substation is connected with the switching stations, and each switching station is connected with the power distribution stations. The method comprises the following steps that firstly, a main distribution network structure is built according to the space layout between the transformer substations and the switching stations; secondly, a secondary distribution network mode is built according the number of the power distribution stations needing to be arranged within the power supply range of each switching station. The hierarchical structure and function location of the medium voltage distribution network are further refined and defined. On the basis of a power supply ability theoretical calculation method and a main transformer handshaking structure optimization model in a power supply module, a typical power supply handshaking model in a switch station power supply mode, the transformer substations and a binding character analysis mode are built, and specific configuration calculation is performed on the switching stations in a typical power supply mode.

Description

technical field

[0001] The invention relates to a power distribution network system, in particular to a method for layering and partitioning a 10KV medium-voltage distribution network. Background technique

[0002] With the increase of urban power load and the gradual expansion and upgrading of medium-voltage distribution network, the urban distribution network structure is becoming more and more complex. Therefore, effectively sorting out and standardizing the structure of the 10 kV distribution network structure is more and more important for improving the operation and management level of urban power grids. more significant meaning.

[0003] In most cities in my country, due to the unbalanced regional load development and the lack of unified and overall planning of the medium and low voltage distribution network structure, the 10 kV distribution network structure has always been in a complex and uneven state. This kind of operation state has hidden dangers both in terms ...

Embodiment Construction

[0049] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0050] The 10KV medium-voltage distribution network includes: multiple substations, multiple switching stations and multiple distribution stations; each of the above-mentioned substations is connected to multiple switching stations, and each switching station is connected to multiple distribution stations.

[0051] Such as figure 1 As shown, the backbone network, that is, the 10 kV backbone line from the low-voltage side of the 110 kV substation, mainly includes the incoming line of the switch station and a small number of 10 kV dedicated lines. The present invention is to construct the backbone network mainly based on the power supply mode of the switching station.

[0052] Such as figure 2 As shown, the secondary network mainly refers to the 10 kV network composed of the switch station and the outgoing line ...
