By combining multim edia technology and TCP/ IP based network technology with the substation autom ation,a new idea of substation multim edia automation system is proposed to realize digitized transm ission of m ultimedia information between master station and substation. The architecture and functions of the new substation multim edia automation system are explained.Two m ain technical problems about the system are analyzed,that is,camera selection and teletransm ission of the inform ation. A scheme for adding the function of multimedia information acquisition and transm ission to the existing substation autom ation system by adopting the multimedia RTU is also proposed.
