摘 要：分析了有源濾波器與無源濾波器的工作原理，針對獨立小容量電網(wǎng)頻率波動范圍大、系統(tǒng)阻抗不可忽略且脈沖型諧波對系統(tǒng)影響大的特點，提出使用有源濾波器作為獨立小容量電網(wǎng)的濾波手段。Matlab仿真驗證了有源濾波器在獨立小容量系統(tǒng)諧波抑制中的正確性和有效性，選用柴油機作為小容量電源帶諧波負(fù)載進行實驗測量分析，結(jié)果表明有源濾波器作為小容量系統(tǒng)的濾波手段，能夠有效濾除諧波。

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
