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...

Embodiment Construction

[0032] This technology is suitable for the design and construction of 35kV substations in remote areas.

[0033] The method discloses a power distribution idea based on a 35kV substation, which is applicable to the construction field of small substations in remote areas. In order to determine the set of influencing factors for the construction of 35kV substations, this method forms different configuration construction modes according to the selection and layout of the main equipment of 35kV substations and 10kV distribution transformers; it summarizes and proposes typical distribution models for 35kV substations suitable for different application conditions The construction mode defines the applicable conditions and scope of application of the typical construction mode of 35kV substation power distribution; conducts power grid engineering design for the typical construction mode of 35kV substation power distribution. The 35kV substation power distribution construction mode of ...
