摘要：
Due to electromechanical scale control characteristics of wind turbine and virtual synchronous generator(VSG) control that simulates operation of synchronous generator，there is the problem of electromechanical dynamic stability in the grid-connected system of grid-forming permanent-magnet synchronous generator(PMSG)-based wind turbine．The electromechanical scale analysis model of the system was established，and two oscillation modes that affected the system stability and dominant control links were extracted through eigenvalue and participation factor analysis．The path for each control link on the system mode damping and the influence law of control parameters for two modes were studied through the damping torque analysis method．It is found that for oscillation mode 1，the grid-side terminal voltage control branch provides negative damping，which is greatly affected by the terminal voltage control parameters and is less affected by the system power level．For oscillation mode 2，the speed control，the pitch angle compensation control and the pitch angle control affect the total damping of the system by affecting the damping of the corresponding path，and the influence of power level on the total damping is strongly related to the proportional coefficient of the pitch angle control. © 2024 Huazhong University of Science and Technology.
