Abstract

The invention discloses an automatic electric power fault detection device. A current transformer and a voltage transformer are installed in an electric power circuit. The output end of the current transformer and the output end of the voltage transformer are connected with the input end of a power grid fault analysis device through an analog-to-digital conversion device. The output end of the power grid fault analysis device is connected with the input end of a server. The output end of the server is connected with a fault diagnosis module. The current transformer and the voltage transformer are used for detecting current simulation signals and voltage simulation signals of the electric power circuit, converting the current simulation signals and the voltage simulation signals into current digital signals and voltage simulation signals and inputting the current digital signals and the voltage simulation signals into a power grid fault analysis device. The power grid fault analysis device carries out comparison analysis on the input current digital signals and the input voltage simulation signals with standard signals stored in a system so as to determine fault signals. The server is used for receiving the fault signals so as to position fault points and carry out fault diagnosis through the fault diagnosis module.

Description

technical field [0001] The invention relates to an automatic power failure detection device. Background technique [0002] With the rapid expansion of the power transmission line network, the working conditions of the power system become more complex, and the impact response generated in actual operation often causes huge damage to the power grid, and even affects the stable operation of the power grid.
