The integration of large-scale wind power，photovoltaic and other renewable energy resources for the power system will greatly change the power supply characteristics，reducing the inertia of power system and threatening the stability of transient frequency. The virtual synchronous generator（VSG） technology can improve the inertia of renewable energy to promote the stability of transient frequency. In order to quantitatively describe the characteristics of transient frequency of VSG and enhance the control ability of VSG，the transient frequency model of VSG needs to be studied urgently. Based on the VSG control strategy of renewable energy，considering the inertial response，primary frequency regulation of renewable energy，the transient frequency model of VSG was established，and a Matlab/Simulink based simulation model was built to verify the validity of the established analytical model. Finally，the influence of different control parameters on the transient frequency of VSG was analyzed，and the effect of control parameters on the transient frequency of VSG was clarified，giving the guidance for system frequency stabilization.
