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.
