摘　　要：基于IEC61850面向对象进行变电站馈线微机保护建模,根据馈线配置的保护方式和所要完成的功能进行功能分解,再逐步合成建立保护信息模型、信息交换模型,合理地选择智能电子设备IED的配置。以FPGA为处理器实现保护功能。FPGA的并行性、流水线和有限状态机设计思想,可以使整个逻辑电路更为合理、稳定。FPGA用于实现物理层通信芯片和网络协议互连的粘合逻辑,将通信和网络功能合并到同一设备中,具备较好的互操作性。并用Quartus Ⅱ进行保护功能仿真。An object-oriented model for substation feeder digital protection is established based on IEC61850. Functions are decomposed according to the feeder protection methods and functions to be accomplished. Then the fimetions are gradually synthesized to establish the protection information model and infonnation exchanging model, and choose a reasonable configuration for intelligent electronic device. The protection functions are realized using an FPGA processor. Parallelism, pipelining, and finite state machine design of FPGA can make the whole logic more reasonable and stable. FPGA is used to implement the glue logic of physical layer communication chip and network protocols interconnect. Functions of communications and network will be merged into the same device with a better interoperability. The protection functions are simulated using Quartus Ⅱ.
