【Abstract】 The circuit structure, the control method, the work principle and the system characteristics of the shunt active power filter system are discussed and analyzed, which are built into models and simulated by the Power System Toolbox of Matlab. The SAPF prototype can compensate harmonics and reactive well under varies load conditions, especially in the case of a distorted or unbalanced current of power supply. Simulation experimental results show this scheme has perfect harmonics compensation performance and has generalization of the proposed method. Active Power Filter (APF) is being considered as a potential candidate for solving harmonic problems in order to meet harmonic standards and guidelines.更多还原
