Application Abstract: This topic involves the key technology of power system component modeling and simulation,which is an important part of the key technical standard system of UHV AC-DC hybrid power grid operation,and provides data model basis and technical means for power grid operation analysis.The six standards included in the project provide model basis and data reserve for the research of other projects from three aspects:Component Modeling and parameter measurement(including DC,generator excitation and speed regulation),equipment model parameter and operation data management,simulation technology and test specification(including real-time digital simulation and digital analog hybrid simulation).Among them,six standards are:Standard 1:technical guidelines for electromechanical transient simulation modeling of DC transmission system;standard 2:guidelines for excitation system modeling of synchronous generator;standard 3:guidelines for measurement and modeling of parameters of speed governing system of synchronous generator;standard 4:Specifications for model parameters and operation mode data of power grid equipment;standard 5:technical specifications for real-time digital simulation of power system;standard 6:direct Specification for modeling and test of mixed simulation of flow engineering.
