The invention discloses a power grid integrated information remote access method. The method includes allowing a local control center to transmit a power grid integrated information remote access service request to a remote control center, allowing the remote control center to make decisions according to the remote access service request and return image files to the local control center, and allowing the local control center to analyze the image files and transmit an image data service request to the remote control center; allowing the remote control center to query real-time data indexes in a power grid integrated information database according to the content of the image data service request, acquiring the power grid integrated information data according to the indexes, and transmitting the power grid integrated information data to the local control center after power grid integrated information combination; allowing the local control center to receive and display the power grid integrated information data. Thus, the share and exchange of the power grid integrated information of different control centers can be implemented, and the practicality level of power grid integrated information monitoring is raised effectively.
