Simulation Of All-Digital Protection Systems And Reseach Of The Evaluation Platform

With the application of Non-Conventional Instrument Transformers, the publishing of IEC 61850 and the technical maturity of the intelligent breaker, it is inevitable for protection systems to transform from conventional protection systems to all-digital protection systems. Since the application of the Non-Conventional Instrument Transformer and the Optic-Fibercommunication network are the distinct characteristics of all-digital protection systems, this thesis will focus on the influence of these two key technologies on all-digital protection systems by using an evaluation platform.First, the thesis introduces an open, integrative simulation system of microprocessor-based protection, which integrates the fault simulation system, the protection simulation system and the protection evaluation system in a complete system by using MATLAB. It realizes synchronous running of fault transient calculation and simulation procedure of microprocessor-based protection, when the former is based on ATP and the latter is based on...
