The invention discloses an electric power equipment monitoring system. The electric power equipment monitoring system comprises a man-machine operation module, a central control module and a control command preview module; the man-machine operation module is used for users to input control commands, obtaining the identity authentication data of the users and transmitting the control commands and authenticated identity information to the central control module; the central control module is used for sending the control commands to the control command preview module, classifying the control commands according to the identity information corresponding to the control commands and storing the classified control commands; the central control module is also used for sending confirmed control commands to corresponding components according to results returned by the control command preview module; and the control command preview module is used for displaying the control commands in a simulation manner and confirming or cancelling the control commands. According to the electric power equipment monitoring system of the invention, the input of each control command carries identity information, so that the input of each command is traceable; each control command is required to be pre-viewed before the control command is confirmed to be outputted, and therefore, the error of the output of the control commands can be well avoided, and each control command has visibility.
