摘要：
The effect of the delay time on the reference signal for compensation due to the data acquisition and digital signal processing is examined. The time delay will cause incorrect compensation and unwanted remaining non-active power after compensation. A theoretical evaluation is done on the negative effect on compensation due to a single frequency distortion. This evaluation is expanded to handle multiple harmonic distortion to calculate the total theoretical ineffectivity of compensation for a specific load due the a specific time delay. Finally, the theoretical evaluations are validated by means of experimental results.
