The Automation System Design Of Kaiping110kV Qilong Station Based On IEC61850

In power system, the current, the requirements of substation automation to more andmore high, for the convenience of the management of the substation IEDs and equipment theinterconnection of, you need an universal communication ways. IEC61850put forward akind of public communication standard equipment, through a series of standardized, make itsformed a standard output of the system, realize seamless connection.This paper introduces the research background, IEC61850situation at home and abroad,significance and contents, and expounds and analyses the IEC61850standard modelingprocess. And from IEC61850standard itself, analyses IEC61850in digitized substation therealization method, including substation layered structure system, far move communicationmode and equipment requirements, etc. At the same time the standard of the defects in thetransformer substation use and limitations to a certain extent explored.The110kV Kaiping QiLong digitized substation construction, for example, the specificimplementation of standard of IEC61850carried on the discussion and analysis.
