【摘要】 研究了电力系统中典型的谐波源。通过探讨串联型和并联型APF的工作原理，分析了它们对不同性质谐波源的补偿特性，并分别进行了仿真和实验研究，确定了它们各自适应的补偿对象。最后得出的结论能为工程应用中选择APF提供理论依据。更多还原

【Abstract】 The models of typical harmonic sources in powe r system are investigated By discussing the operation principles of the shunt a nd the series active power filters,their compensation characteristics to differe nt types of harmonic sources are analyzed For verification,a great number of si mulations and experiments are done and the results are compared On the basis of these,the suitable compensation objects and applicable range of different types of active power filters are determined The conclusions can provide considerabl e theoretical basis and practical guide for the engineering applications of acti ve power filters更多还原
