| Abstract: | Considering limitations of the passive power filter (PPF), a reform method of PPF for low voltage power grid was presented. On the basis of installed PPF, connecting active power filter to PPF by small inductor, a hybrid active power filter was designed. The selection of harmonic inspection and control method for active filter and certainty of last added compensation capacity and quality factor were expounded. The experiment and simulation results show that the reform method can damp harmonic resonance and improve the filtering effect. |
