In the field of power system automation, the IEC61850 standard is the only global universal standard, and the standard realizes the engineering operation standardization of the intelligent substation, so that the engineering implementation of the intelligent substation becomes standard, uniform and transparent. However, some smart devices that do not meet the IEC61850 communication standard still exist, and protocol conversion is performed through an IEC61850 protocol converter to realize the IEC61850 communication standard. As disclosed in the chinese patent application "a protocol converter for substation automation system" (published patent number CN104023026a, 2014.09.03), the technical solution of converting data of different communication protocols generated by intelligent devices of non-IEC 61850 communication standard into IEC 61850-based data is realized.
