摘　　要：提出了在SCADA系统的主站局域网内 ,采用TCP/IP通信协议使主站与子站之间可利用上、下行数据直接通信 ;采用COM组件技术设计TCP/IP协议的单播通信模块的实时性已经多次测试证明完全满足目前电力系统的要求 ,且其数据完整性。This paper bring forward a constitution. That is to adopt TCP/IP protocol within local network of master station and make direct communication between master station and slave stations of SCADA system by using up data and down data. Author has designed network communication model of TCP/IP protocol unicast in master times, the real-time performance completely meet the demand of present power system and data integrality and correctlity is improved greatly comparing with traditional UDP/IP broadcast transmission mode.
