Indirect power failure judgment method

The invention discloses an indirect power failure judgment method, which comprises the following steps: arranging acquisition terminals at each metering point in a power grid to collect power grid data, putting the collected power grid data into a metering automation system, and outputting real-time data after power grid monitoring analysis by the metering automation system. Power grid monitoring real-time data is subjected to main and distribution network topology linkage to accurately find a power failure position, a distribution network automatically contacts with an expert to judge a fault diagnosis method through modular design, and rapid power recovery work is achieved. The indirect power failure judgment method not only effectively integrates the alarm information of the main network, but also performs real-time monitoring on the power failure of the distribution network based on the real-time fault monitoring model of the distribution network line and the metering automation real-time monitoring data,
