Power supply mode selection method of area without electricity supply based on load distance and load characteristic

Abstract

The invention relates to a power supply mode selection method of an area without electricity supply based on a load distance and a load characteristic. Based on a survey of a present situation of the area without electricity supply, an appropriate power supply mode is provided. Each mode lists each characteristics and a suitable scope. The method is characterized by: measuring and calculating load and line power supply distances of the area without electricity supply; calculating and determining whether the distances satisfy a load distance requirement; determining the corresponding power supply mode according to the load and the load characteristic. By using the method, a set of selection process of the power supply modes of the area without electricity supply can be established. A selection difficulty of the power supply modes of the area without electricity supply can be substantially reduced. A feasible scientific technology which can solve a power supply problem of the area without electricity supply can be provided. In the invention, the method is combined with the actual area without electricity supply. The area without electricity supply and a power distribution network of the adjacent power supply area can be deeply analyzed. A bottleneck of implementing power grid extension power supply can be found and a power supply problem of the area without electricity supply can be effectively solved.

Description

Technical field: [0001] The invention relates to the field of distribution network planning, and specifically designs a method for selecting a power supply mode in a non-electric area based on load distance and load characteristics. Background technique: [0002] At present, in some remote plateau agricultural and pastoral areas with inconvenient transportation and scattered ethnic minorities, the problem of electricity consumption has not been fundamentally resolved. On the other hand, due to the ecological immigration, farm adjustment projects and small town construction organized by the government in recent years, some new households without electricity have been added; New households without electricity have been re-formed. In order to solve the problem of power supply in areas without electricity, many areas blindly implement power grid extension power supply, which not only caused a lot of waste of investment in grid construction, but also failed to effectively guaran...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned power supply problems in the vast areas without electricity mainly rely on the extension of the power grid or the household photovoltaic power supply mode to temporarily solve the power consumption problem. However, the existing solutions generally have a large blindness and always lack a scientific method The method of power supply mode selection will be a major bottleneck that seriously restricts the power supply problem in areas without electricity. It is urgent to invent a scientific, reasonable and operable method to effectively solve the power supply problem in areas without electricity
