Abstract: The bottleneck between Intranets and control nets is an important problem for power plant control and management. Service gates based on OPC can be a solution to the problem. OPC, which is an open industry standard, can standardize the data communication in power plants and integrate Intranets and control nets. OPC service gates can be employed to transmit real-time data, to monitor system load and so on. Based on the analysis of Intranets and control nets, a scheme that utilizes OPC service gates is proposed with detailed explains of its key technology. OPC service gates can solve the problems including availability, real-time, security, network address translator(NAT) and so on.
