Meshed connection smart distribution network system

Abstract

The invention discloses a meshed connection smart distribution network system comprising a plurality of transformation regions, a plurality of connection switches and a background expert system. The plurality of transformation regions are connected through the connection switches to form a mesh shape. All the transformation regions have access to a power grid and are in wireless communication connection with the background expert system. The meshed connection smart distribution network system reasonably distributes loads, enhances a system power supply capability, reduces loss, can control a voltage regulator and a three-phase unbalanced control device in a centralized way, eliminates harmonics, improves a power factor, and achieves a purpose of improving power supply quality.

Description

technical field [0001] The invention relates to an intelligent power distribution system, which belongs to the technical field of intelligent power utilization of smart grids. Background technique [0002] With the development of the rural economy, the low-voltage power grid has undergone the construction and transformation of the first and second phases of rural power grids, which basically meet the requirements of rural electricity consumption, but there are still: a single transformer power supply, low reliability, and the "hand in hand" structure in some areas The post-management level needs to be improved; the load forecasting method is simple, the accuracy of operation planning is low, and the response ability to emergencies is weak; the three-phase unbalanced load, unqualified terminal voltage, and the existence of reactive power and harmonics are serious; The accurate location, removal and self-healing ability of the fault point are poor; the equipment operation loss...
