摘　　要：提出了在SCADA系统的主站局域网内也采用TCP/IP协议通信,使得具有SCADA系统的主站与子站之间利用上行数据和下行数据直接通信的构想。采用目前流行的组件对象模型(COM)技术,在SCADA系统的主站局域网中设计了TCP/IP协议单播的网络通信模块。经多次测试表明,其实时性完全满足目前电力系统的要求,且其数据完整性、纠错性比传统的UDP/IP广播传输方式有很大的提高。It is proposed to adopt TCP/IP protocol within local network of master station,which makes the direct communication of upward data and downward data possible between master station and slave stations of a SCADA system.Applying COM technology,a network communication module of TCP/IP protocol unicast in master station is designed.The tests show that its real-time performance meets the demands of present power systems completely and its data integrality and error-correction ability are improved greatly.
