UPQC compensation detecting has characteristics of high precision and fast dynamic response. The article gave the solution in order to mitigate the influences of hardwire and calculation delay problems which existed in compensations detection used synchronous coordinate transformation without PLL. The accuracy has been improved by correcting the reference rotation angle in the matrix of synchronous coordinate transformation to compensate the delay coursed by hardwire circuit such as sampling. Meanwhile, state feedback was introduced to make up the calculation defect of low-pass filter in to speed up dynamic response. Finally, the simulation results verified that this solution applied in UPQC compensation detection is feasible and effective.
