A Method of Remote Interactive Control in Electricity SCADA System Based on Internet

摘要

Electricity SCADA system faces a series of complex requirements to be studied and analyzed carefully .This paper firstly investigates the importance of remote control interface on electricity SCADA system, then propose a new scheme for remote control based on Internet. This paper introduces the details of RCI status in SCADA system and general RCI structure. The remote control center's access process and software implement with IEC protocol is given. The web technology makes the system presenting data simply and being accessed at random location. Finally, this paper analyze the security in such a system based on Internet and discussed the security measures.
