Abstract

The invention discloses a distributed fault positioning system and method based on WIFI. The system comprises a plurality of wireless network modules and a plurality of wireless power distribution terminal modules. Each wireless power distribution terminal module comprises an input and output assembly, a wireless communication module, a communication management assembly, a data processing assembly, a signal controller and a message management assembly. The signal controller is in two-way connection with the input and output assembly, the message management assembly, the data processing assembly and the communication management assembly. The communication management assembly is connected with the wireless communication module and the data processing assembly. Electrical quantity information of the terminals is obtained in real time; a section with a fault is judged according to a calculation result; and an interval with the fault is automatically isolated by a control switch. The system and the method provided by the invention are applicable to the occasion on which an optical cable cannot be laid or the laying of the optical cable is difficult; communication is carried out in a wireless network mode, so distributed power distribution automatic fault processing is realized, and the problem that communication among power distribution terminals is difficult is solved.

Description

technical field [0001] The invention relates to the technical field of power system distribution automation, in particular to a WIFI-based distributed fault location system and method. Background technique [0002] In power supply enterprises, feeder automation (FA) is designed to improve the reliability of the system. It judges the fault current based on the measurement data collected by the distribution terminal (Feeder Terminal Unit, FTU), quickly isolates the fault and restores the non-fault zone. Power service, which can reduce the time to restore power to non-faulty areas from hours to minutes. [0003] Traditional FA solutions are based on a centralized architecture, which relies on a powerful control center with high-speed communication capabilities that can handle large amounts of data. This dependence may lead to single point failure problems. Moreover, with the increase of load and frequent changes of site topology, the traditional centralized master station grad...
