The present invention relates to a power transmission project intelligent evaluation system which comprises a server which emits various commands and file information to the outside, several clients which receive the file information and carry out information exchange with the server, a transfer processing unit which receives and analyzes the file information and then sends an analysis result to each of the clients and multiple document storage units synchronously, and a document storage unit used for temporarily storing the file information and completing the information exchange with the server, the clients and the transfer processing unit. The system has the advantages that since the power transmission project intelligent evaluation system is formed by a conference server, a number of client devices, a transfer unit and the document storage unit, handshake interaction agreement is employed by each of the client devices and an electric whiteboard device and a file service device cluster, the data remote synchronous transmission is realized, and the safety of data communication is effectively protected.
