摘  要:在数字化变电站中,面向通用对象变电站事件(GOOSE)报文被用于传输跳合闸命令和状态信息,它直接服务于保护测控装置,记录变电站实时的运行状态,报文的快速解码能及时的排查偶发性故障。在详细地分析IEC61850-GOOSE报文的结构后,考虑到报文传输的实时性要求,提出了GOOSE报文解码的FPGA设计方案。重点叙述解码模块中两个关键状态机的设计,应用Verilog硬件描述语言在QartusⅡ软件平台上实现了对解码模块的编写,最后通过对解码模块的功能仿真和在线调试验证了设计的合理性。In digital substation,general object oriented substation event (GOOSE) messages are used to transmit the switch command and status information. The messages are applied to protecting the measuring and control devices,and recording the real-time running state of the substation. The fast decoding to the messages can discover occasional malfunction. After analyz-ing the structure of IEC61850-GOOSE messages,the FPGA-based design scheme of GOOSE messages decoding is proposed by considering the real-time requirement of messages transmission. The design of two key state machines in decoding module is de-scribed emphatically. The compiling of decoding module was realized on Qartus Ⅱsoftware platform by using Verilog hardware description language. The rationality of this design was proved by function simulation of the decoding module and online debug-ging.
