In recent years, smart grid covers the contents of raising science and technology of power grid, improving the reliability of power supply, promoting energy conservation and emissions reduction, and promoting new energy uti-lization efficiency.It has become the mainstream direction of change and development in today's world power system. Under this background, higher request for the development of device status online monitoring and condition assessment are also put forward.Communication networks acting as a bridge which connects all key areas in the smart grid frame. Its performance will directly affect the security and reliability of the whole system.This paper analyzes the problems and the development trend, which exist in the substation equipment condition monitoring system, and introduces the development status and main content of the IEC 61850, as well as analyzes and compares to the Ethernet network mode.Finally, it analyzes and presents several seamless communication schemes.
