In order to reflect,evaluate and improve the domestic supercritical unit's ability of participating in grid frequency regulation under different load conditions,the mathematical models of these supercritical thermal power units under different loadconditions were established,according to the lumped parameter method.Thus,the change rules of key parameters of these units under varying load conditions were ob-tained.On this basis,the control system models which are suitable for supercritical units were built.The frequency regulation dynamic simulation under different load conditions was carried out by using Simulink of the Matlab software,which demonstrated the effectiveness of the supercritical unit load frequency mod-els.The results show that these models provide a platform which can improve and evaluate the unit's ability of participating in the grid frequency control under different load conditions.
