Abstract

The invention provides an integrated intelligent ring main unit system, an intelligent power distribution network and a fault positioning method. The intelligent power distribution network comprises the intelligent ring main unit system. Each interval unit of the system is provided with an independent DTU. Primary equipment and secondary equipment are integrally mounted; the DTUs can perform information interaction with the adjacent DTUs and a power distribution main station. The feeder line section where fault current is detected and the fault current is not detected at the downstream is a fault section; and rapid fault isolation is realized through tripping of a circuit breaker, fault recovery at the upstream of the fault section is realized through reclosing of the circuit breaker, andfault recovery at the downstream of the fault section is realized through closing of an interconnection switch. The method is suitable for quick fault positioning, fault isolation and fault recovery of the intelligent power distribution network with a high power supply capacity grid frame, realizes a quick self-healing function of the intelligent power distribution network, and improves the powersupply quality and the power supply reliability.

Description

technical field [0001] The invention relates to the technical field of a ring network cabinet and an intelligent distribution network, in particular to an integrated intelligent ring network cabinet system suitable for a smart grid, an intelligent distribution network and a fault location method. Background technique [0002] With the continuous improvement of people's quality of life and the continuous improvement of the demand for power supply reliability, the smart grid has developed rapidly. The smart distribution network is directly oriented to users, has a complex structure, and has a high failure rate, which is the main link that affects the reliability of power grid power supply. In order to give full play to the advantages of the smart distribution network and improve the reliability of power supply, it is urgent to upgrade the distribution network equipment. The ring main unit is the key equipment of the distribution network, and its performance directly affects t...
