Electrical monitoring system and joint debugging method thereof

The invention discloses an electrical monitoring system and a joint debugging method thereof. The electrical monitoring system comprises a centralized control center, a first main network, a second main network and a plurality of substations, the centralized control center is in communication connection with the first main network and/or the second main network; the plurality of substations are in communication connection with the first main network and/or the second main network; the centralized control center is in communication connection with the plurality of substations through the first main network and/or the second main network; the centralized control center is used for monitoring the substations. By the adoption of the technical scheme, construction, debugging and operation can be carried out at the same time, normal operation of other substations is not affected while all debugging work that the substations to be updated and upgraded are connected to the monitoring background of the centralized con
