This paper analyzed and researched the performance and principle of DSTATCOM in distribution network. Detecting means and control method of DSTATCOM were key point of this paper. The paper determined the detecting means of improved d-q transformation theory of vector control based on instantaneous reactive power and adopted a novel strategy Based on the prediction table of double variahle. Moreover, the simulation of DSTATCOM was presented with MATLAB. The simulating results proved that the DSTATCOM mentioned in the paper can realize dynamic reactive power compensation efficiently.
