摘要 多媒体技术应用于变电站自动化中可实现视频、音频信息的采集和远传 ,以满足变电站环境监控等功能需求 ,对变电站实现真正的无人值班具有重要意义。文中阐述了影响多媒体技术在变电站自动化中应用的 3个方面的因素 :视频传输、多通道输入的整合和经费限制 ;给出了变电站自动化中实现多媒体通信的两种典型实现模式 :点对多点实现模式和广域网络 (TCP/IP)实现模式 ,并进行了分析比较 ,指出广域网络 (TCP/IP) By applying multimedia technology to the substation automation can implement the acquisition and teletransmission of video and audio information to meet the needs of substation environment monitoring and so on, which is advantageous to realizing genuine unattended substation. Three factors are presented that are of influence on the application of multimedia technology to substation automation, which are video information transmission, the integration of multi-modality input and engineering funds. Two typical modes of communication between master station and substation are given and analyzed, one is the point-to-multipoint and the other is the wide area network (TCP/IP) mode. It is pointed out that the wide area network (TCP/IP) mode is the trend of technological development.
