Abstract: This paper proposes an effective control method for the wind power grid connected transient energy disturbance under impact load. The wavelet transform is used to decompose the collected wind power grid-connected transient voltage signal and the disturbance time of the signal is determined. The detection of the wind power grid-connected transient energy disturbance is completed. The mathematical model of DSTATCOM is constructed to complete the independent control of active and reactive currents for the wind power disturbance,and achieve the reactive power compensation. The power system stabilizer（PSS）is installed in the automatic voltage regulator（AVR）of the synchronous generator（SG）in the grid-connected system to improve the damping and stability of wind power grid connection. The test results show that under different signal-tonoise ratio conditions,the tracking error of PI controller of the proposed method is small with no more than 0.5,which has good tracking performance and immunity. Under two shock loads of6 000 MV·A and 7 000 MV·A,the control of grid-connected transient power disturbance of wind power is effectively realized under different shock loads,which further improves the power quality.
