In order to deal with the problem of frequency/voltage stability of power system with high proportion of wind power, the theoretical basis of virtual synchronous control is introduced. The mathematical models of Doubly-Fed Induction Generator (DFIG) and traditional synchronous machines are compared and analyzed. Based on the similarity of models, the electromotive force, power angle, and power transmission equations of Wind Turbine Virtual Synchronous Generator (WT-VSG) are deduced, whose change regulations are revealed. A virtual synchronous control strategy of wind turbine with damping coefficient is researched. The design of virtual synchronous control outer loop and current control inner loop is performed. In Matlab/Simulink, the simulation model of the WT-VSG is established. The whole process simulation of the inertia, damping, primary frequency control, and reactive power-voltage regulation of the WT-VSG is realized. The simulation results confirm the correctness of the theoretical analysis and the effectiveness of the control strategy.
