Abstract

Non-invasive fault monitoring and locating system due to the low installation and maintenance cost and non-invasive the use house has become an important development direction of load short-circuit fault identification and positioning. The paper constructs the overall architecture of non-invasive electricity safety monitoring systems and the test platform of the short circuit-faults, analyse short-circuit current feature, and proposes a non-invasive short-circuit fault identification and location algorithm based on short-circuit mutational current and direct component in the power supply network. This algorithm solves the key technical problems of short-circuit current criterion when breaker operates under the non-invasive fault monitoring architecture, and effectively identifies and locates the rough region of short-circuit fault for the power supply network. If the low voltage feeder circuit smart meter can transmit the fault massage to the main station, the algorithm can locate the fault precisely.
