| Popis: | The function real-time of substation automation system based on IEC61850 depends on the distribution mode of logical nodes, the processing speed of logical nodes and the communication delay between logical nodes.The realization principles of functions free distribution are introduced based on IEC61850, take bus protection function and distributed interlock function examples, the functions are deposed into the connection diagram of logical nodes and their communication events are introduced in great detail. The simulation models of D2 substation which has unified network or two-tier network are established with OPNET. The communication events of bus bar protection function and distributed interlock function are simulated and analyzed based on this mode. The rationality of distribution mode of systems functions is quantitative analyzed which provide guidance to improve the real-time performance of systems functions and network structure. |
