Abstract: Analysis was made to the working principles of active power filter and reactive power filter. Aiming at features that the independent small capacity power network had large frequency fluctuation, the system impedance couldn’t be neglected and the pulse harmonics had large impacts on the system, this paper raised taking the active power filter as filtering measures for independent small capacity network. Matlab software simulation has verified the correctness and validity of active power filter in harmonic suppression of independent small capacity system. The diesel engine was selected as small capacity power with harmonic load to carry out experimental measurement analysis. The result shows that the active power filter as filtering measures for small capacity system can effectively filter out harmonic waves.
Key words: independent small capacity power network; harmonic suppression; reactive power filter; active power filter
