One kind of the grid with a single relatively short-circuit fault location method

The present invention discloses a single relatively short-circuit fault location method comprising: a step of: setting a single grid is relatively short-circuit failure criterion; Step two: real-time monitoring with a single occurrence of the grid is relatively short-circuit fault; step three: when they find a single relatively short-circuit fault occurs with the grid, the host alarm monitoring, fault location and start the function modules, and each smart meter communication, and communication based on the results of smart meter positioning possible short-circuit fault location. Step four: the staff at the scene confirmed the fault location. The present invention is not only single-phase short circuit fault occurs with the power grid in real time alarm and electric energy by reusing short circuit fault location table, the statistics ultimately short-circuited the power grid frequency, time of occurrence, the short-circuit location. The present invention will provide technical support and security risks, accident analysis and other electrical safety action advanced services.
