主　　题：active power filter digital signal processing modeling compensation error 

摘      要：The growing problems of harmonic pollution on coal mine power lines caused by high-power DC drive systems has increased the use of active power *** analyzed compensation errors caused by the time lag in the detecting circuits of an active power filter based on DSP *** derived a mathematical model for the compensation error starting from the error estimation when a single distortion frequency is *** model was then extended to the case where multiple frequencies are present in the distortion.A formula for a general theory of compensation error with fixed load and fixed lag time is *** theoretical analysis and experimental results show that the delay time of an active power filter mainly arises from the sampling *** sampling frequencies introduce larger compensation errors in the active power filter reference current.
