Power system planning method suitable for power supply in remote area

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 specifically relates to a grid planning method suitable for power supply in remote areas. Background technique [0002] In our country, remote areas are geographically remote, vast, inconvenient in transportation, bad natural environments in some areas, and relatively backward economic and social development. For a long time, the construction of its regional power grid has been relatively lagging, with fewer power sources, and long transmission and distribution distances. Under the current situation of rapid and stable economic growth, power grids in remote areas cannot be better in terms of substation capacity, power supply quality, and management level. To meet demand. In addition, some remote areas are still in a state of no electricity so far, and there is a problem of power supply difficulties. [0003] When solving power supply problems in remote areas, there are currently two methods commonly u...
