A design method for power distribution of 35kv substation in remote areas

Abstract

The invention provides a design method for power distribution of a 35kV transformer substation in a remote region. The design method comprises the following steps that (1) the influence factor set of the design of the 35kV transformer substation is determined; (2) the model selection and configuration scheme of main equipment and the layout mode of the power distribution building of the 35kV transformer substation are determined; (3) the power distribution building mode of the 35kV transformer substation is formed; (4) the application condition and the application range of the power distribution building mode of the 35kV transformer substation are determined; and (5) the power distribution building mode of the 35kV transformer substation is subjected to power network engineering design. The design method for the power distribution of the 35kV transformer substation in the remote region provided by the invention solves the building problem of low and disperse load of the 35kV transformer substation in the remote region, the building mode of the 35kV transformer substation is specified, the resource optimization configuration is realized, and the power demand of power users in the remote region is met.

Description

technical field [0001] The invention belongs to the field of power distribution construction, and in particular relates to a design method for power distribution of 35kV substations in remote areas. Background technique [0002] In our country, some rural areas are geographically remote, economically developing slowly, the power load is small and scattered, and the grid power distribution is seriously insufficient. In remote rural areas and mountainous areas, a large amount of funds have been invested in the construction of conventional 35kV substations according to medium and long-term plans, but they face difficulties such as difficult site selection, high cost, and long construction period. Low, resulting in a lot of waste of resources. [0003] At present, there are two main ways to build 35kV substations in rural areas in remote areas. The first is to use standardized design to build conventional 35kV substations; the second is to build 35kV simple substations; but bot...

Problems solved by technology

In remote rural areas and mountainous areas, a large amount of funds have been invested in the construction of conventional 35kV substations according to medium and long-term plans, but they face difficulties such as difficult site selection, high cost, and long construction period. Low, causing a lot of waste of resources

[0003] At present, there are two main ways to build 35kV substations in rural areas in remote areas. The first is to use standardized design to build conventional 35kV substations; the second is to build 35kV simple substations; but both methods have insurmountable problems

The first method has difficulties in site selection, high cost, and long construction period. Due to the characteristics of small load and slow growth in remote areas, it is easy to cause a certain waste of resources, and its applicable area is limited and cannot meet special needs, such as emergency power supply; The two methods have problems such as inconsistent construction standards and unreliable power supply reliability.
