Abstract In 2002 IEC61850 series standard progressively promotion, IEC 61850 protocol to realize the digital substation equipment and equipment interoperability, interchangeability. Digital substation has changed the traditional substation integrated automation two equipment configuration mode, the use of photoelectric (current, voltage transformer and other intelligent device), a device to realize online detection, self diagnosis technique. Along with the digital substation in power system, the application and development of digital technology, reliability, real time, economy is able to reflect, also make digital substation in the full sense of the digital.
