摘要：
In order to solve the problem that the wind turbines do not initiatively participate in the frequency regulation of power grid, the capability of large-capacity DFIG-WT(DFIG-based Wind Turbine) using stored inertia energy of the rotor to participate in the frequency regulation of the power grid is evaluated. A control strategy of virtual inertia frequency regulation of wind turbine based on accessory torque is proposed, and its implementation principles and control strategies are stu-died respectively. A Bladed and MATLAB co-simulation system of large-capacity DFIG-WT is established, realizing the whole process dynamic simulation of virtual inertia frequency regulation. The field test is carried out on a MW class DFIG-WT by large capacity grid emulator for the first time, and the dynamic and technical characteristics of the virtual inertia frequency regulation are revealed. The simulative and experimental results support the theoretical analysis and verify the proposed control strategy. © 2018, Electric Power Automation Equipment Press. All right reserved.
