Research On The Communication Of Fault Recording Data In IEC 61850 Information Models

In order to break through traditional power communication model, and to solve the problem of low communication rate, IEC 61850 is an international standard which is proposed by IEC TC57. The seamless communication of power system is based on the IEC 61850 Standard in the future. The development and main idea of the standard are introduced in this paper. The main technical features of network leveling, unified object-oriented modeling, data object self-description abstraction of communication service mapping tec. Are analyzed in detail. Aiming at the interconnection and inter working problems between IEC 61850IED and traditional device, the IEC 61850/MMS communication gateway based power telecontrol communication method is presented, the software architecture of IEC61850/MMS communication gateway is designed. Using of opnet, the validity and feasibility of the proposed models and methods have been proven.
