Doubly-fed virtual synchronous generator control method based on fast reactive power control and power angle compensation method

The invention relates to the technical field of doubly-fed motor control, in particular to a quick reactive power control and power angle compensation control method for a doubly-fed virtual synchronous machine. According to the decoupling scheme, a fast reactive power control strategy is adopted to eliminate the influence of active power disturbance on reactive power, and a power angle compensation strategy is adopted to eliminate the influence of reactive power reference value disturbance on active power. On the basis of designing an overall control strategy of the doubly-fed virtual synchronous machine, a small signal model of the doubly-fed virtual synchronous machine considering a reactive power control link is constructed. By analyzing the influence of the parameters of the PI controller in the reactive link on the stability of the power angle, rapid reactive control is designed. And setting power grid frequency disturbance and reactive power reference value disturbance working conditions for verificati
