IEC 61850 based substation communication network has greatly improved the interoperability and interchangeability of substation devices, but open and standard protocols have brought about security issues as well. In order to build a perfect substation information security system, IEC TC57 WG15 has developed the IEC 62351 standard. Based on the requirements of IEC 62351 standard, the protocol on secondary system inside the substation is transformed, the key technologies of the implementation process are studied, and a prototype system conforming to IEC 62351 standard is built. A comparison is made between the prototype system and the system without considering IEC 62351 standard. Points for attention in the process are given as a reference for engineering implementation of the IEC 62351 standard. ©, 2015 Automation of Electric Power Press. Source
