采用有源电力滤波器来抑制谐波是当前电力系统发展的一个重要趋势。由于电流检测控制环节决定了有源电力滤波器的补偿性能，所以本文着重研究了谐波电流检测这一问题。同时，对有源电力滤波器的主电路参数和控制电路进行了设计和仿真。 本文主要研究了基于瞬时无功功率理论的谐波电流检测方法。在此基础上提出了单相电路谐波和无功电流的实时检测方法。 所提出的检测方法用模拟电路加以实现，可对谐波电流、无功电流以及负序电流进行分别检测或综合检测。 使用MATLAB仿真软件对各种检测方法进行了仿真研究。
In this thesis, the Active Power Filter (APF) has been used to realize the harmonic suppression is an important developmental trend of current power system. Because the electric current detect block has decided the compensation capability of the APF. Then this thesis emphasizes the research of the question about the harmonic current detection. In the same time, making the design and simulation about the main electro circuit parameter and control circuit of the APF.The research is mainly about the harmonic current detection method that based on the instantaneous reactive power theory. And then put forward the real-time detection of the single-phase circuit and reactive current. The realized methode is the artificial circuit. It can detect respectively or synthetically the harmonic current, reactive current and negative-sequence current.The simulation tool MATLAB was used to study on the simulation.
