The invention relates to a power grid monitoring system based on streaming media. The power grid monitoring system based on the streaming media comprises client sides, a central server, a plurality of sub-servers and a monitoring device. One client side sends a request for obtaining a real-time video stream to the central server. The central server searches for the sub-server where the real-time video stream is located, sends the address of the sub-server to the client side, and meanwhile sends a command for connection establishment to the sub-server. The sub-server packages the video stream obtained from the monitoring device and then sends the video stream to the client side. When other client sides simultaneously send the requests for obtaining the real-time video steam, the sub-servers forward the real-time video stream to the other client sides. According to the power grid monitoring system based on the streaming media, the technical problem that due to hardware limitation, the monitoring device can not meet the requests which are simultaneously sent by the multiple client sides and used for obtaining the video stream is solved.
