| Abstract: | Aiming at the power energy quality problem of customer side due to voltage sag,adoptsdynamic voltage restorer(DVR)to restore the voltage. In order to improve the compensation effect, puts forward the PID control strategy based on DVR instantaneous reactive power dq transformdetection algorithm,and makes simulation in Matlab. The result shows that this control strategy hasclear principle,small calculation,improves the dynamic characteristic of DVR,can effectivelycompensating voltage sag. |
