Embodiment Construction

[0043] The specific implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] The present invention focuses on 35kV power distribution technology, with single-phase and three-phase hybrid power distribution technology and distributed power generation technology as auxiliary and supplementary planning and design ideas, and defines the grid structure (grid wiring mode), power supply, voltage level, and substation construction. The remote area power supply mode includes the economic and social development level, population size, electricity demand, load characteristics, load density, resource status, residents' living habits and geographical environment, etc. The applicable conditions and scope of the remote area power supply mode affecting factors. For different remote areas, according to their regional economic and social development level, population size, electricity deman...

Abstract

The invention relates to a power system planning method suitable for power supply in a remote area. The power system planning method comprises the steps of: determining an influencing factor set of power system planning in the remote area; determining a 35kV power distribution building mode of power supply in the remote area, forming a power supply mode of the remote area and classifying; analyzing an applicable condition and an applicable range of the power supply mode of the remote area; and designing a power system engineering of the power supply mode of the remote area. On the basis of the conventional power system building mode, the power supply mode of the remote area is created, with the 35kV power distribution building as a main part, by combining with a single-phase and three-phase hybrid power distribution technology and a distributed power generation technology, the technical advantages of 35kV power distribution, single-phase and three-phase hybrid power distribution, distributed power generation and the like are fully developed and utilized; aiming at the influencing factor set of power system planning in the remote area, measures are adjusted according to local conditions, problems of difficulty in site selection, high cost, long construction period and the like in the power system building of the remote area are solved, and technical support and basis are provided for power system planning and building of the remote area.

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a power grid planning method suitable for power supply in remote areas. Background technique [0002] In my country, remote areas have remote geographical location, vast territory, inconvenient transportation, harsh natural environment in some areas, and relatively backward economic and social development levels. For a long time, the construction of regional power grids has been relatively lagging behind, with few power distribution points and long transmission and distribution distances. Under the current situation of rapid and stable economic growth, power grids in remote areas are not good in terms of transformation capacity, power supply quality, and management level. meet the needs. In addition, some remote areas are still without electricity, and there is a problem of power supply difficulties. [0003] When solving the problem of power supply in remote areas, the...
