Distribution system and power system

Abstract

The embodiment of the invention provides a distribution system and a power system. The distribution system comprises a three-phase transformer, a single-phase transformer and a flexible compensation device, wherein the three-phase primary side of the three-phase transformer is electrically connected with three high-voltage phase lines of a high-voltage bus respectively for outputting three-phase electric energy corresponding to phase voltage of the three high-voltage phase lines; the primary side of the single-phase transformer is electrically connected with the first high-voltage phase line and the second high-voltage phase line of the high-voltage bus for outputting single-phase electric energy corresponding to line voltage of the above two high-voltage phase lines; and one port of the flexible compensation device is electrically connected with the secondary side of the single-phase transformer, and the other port is electrically connected with the secondary side, capable of outputting electric energy corresponding to the phase voltage of the third high-voltage phase line, in the three-phase transformer. The distribution system and the power system have the advantages that the line loss is small; the power supply quality is high; the power supply reliability is high; power consumption demands by rural residents can be met; and the power consumption experience of the rural residents can be improved.

Description

technical field [0001] The invention relates to the technical field of electric power supply, in particular, to a power distribution system and a power system. Background technique [0002] With the rapid development of rural economy and the increase of rural electricity consumption, the normal operation of rural power grid is becoming more and more important. But as far as the rural power grid itself is concerned, there are still many technical problems to be solved. Among them, how to improve the quality and reliability of power supply in rural power grids is an extremely important issue. [0003] For now, in the prior art, rural power grids usually use scattered villages as units to install one or more transformers in places where residential areas are more concentrated, and conduct unified power distribution in a radial power supply manner. However, this power distribution method has disadvantages such as long transmission line radius, dispersed residential load points...

AI Technical Summary

Problems solved by technology
