摘要: The ip-iq detection method based on instantaneous inactive power theory has been applied widely in active filter because of its good real-time. But it needs large computation, and three-phase currents are processed as integrity, thus calculation accuracy can't be ensured. Based adaptive interference canceling theory, this paper presents a new ad- aptive for harmonic current, is continuously regulated closed-loop system, operating characteristics almost independent the parameter variations elements, performs better than that traditional theory. At last provides simulation including detecting cir-cuit which proved design feasible correct.
