Abstract Fast cut back (FCB) technique plays an important role in power system black-start, and the detailed dynamic model of the FCB thermal unit is the fundamental of the FCB research. However, the current conventional thermal unit model cannot simulate the dynamics of FCB thermal unit accurately. Therefore, after analyzing the required techniques for the FCB function, this paper constructed thermal turbine model with a bypass system and prime mover model integrated a FCB function. After that, the complete dynamic model of FCB thermal units were built, including the turbine, prime mover, boiler, PSS, exciter and generator. A case study is undertaken based on the FCB thermal units in Taishan Power Plant through Matlab/Simulink software. The simulation results are consistent with field test results of the FCB thermal unit, which verify the proposed dynamic model. It can provide references to study FCB thermal units and other large bypass integrated units.
