| Abstract: |
| A control scheme used in hybrid active power filter to compensate both reactive power and harmonic is presented. By translating harmonic elimination into harmonic suppression,it adopts the pole placement control manner without static error for reactive power compensation and suitable harmonic suppression strategy for harmonic compensation. With strict mathematical foundation,the proposed method has strong robustness to the disturbances caused by load variation,parameter peturbations,and unmodel dynamics,and simplifies the harmonic detection. The principle is expounded,and simulations show its effectiveness and satisfying performance. This project is supported by Scientific and Technological Brainstorm Project of Guangdong Province(2004A10502001). |
