随着工业的发展，电力电子装置应用的日益广泛，电网中的谐波污染日趋严重，这严重威胁着电力系统的安全经济运行。为保证国民经济的可持续发展，对电网进行综合控制调控以保证供电质量，对于这方面的研究具有重要的意义。
在查阅了国内外大量有源电力滤波器相关资料的基础上，针对目前有源滤波器实时性不强，性价比不高等缺点，论文提出了基于模拟器件设计电力有源滤波器的思想。论文对有源滤波器的各种电流检测方法作了比较详细的介绍，并重点分析研究了瞬时无功功率法，并在此基础上设计了基于ip－iq算法的模拟式电力有源滤波器的谐波检测电路，以及其它相关电路如PWM控制电路、驱动及逆变主电路等。在Matlab/Simulink仿真环境下，对基于瞬时无功功率理论的电力有源滤波器进行了建模并进行了仿真分析，仿真试验结果说明论文所提出的模拟式电力有源滤波器设计思想的正确性和可行性。
采用该法设计的电力有源滤波器具有较好的动态特性和检测精度，并且它还具有开发成本低，体积小等优点，能很好的模块化、集成化。

Abstract
Along with the development of industry, the electronics and electric devices are used widely day after day, and the harmonic wave pollution in the electric network becomes worse and worse, therefore imperils the safe and economic running of electric system. To keep sustainable development of national economy，it has import significance for this research to integrated control of the electric network.
After referring to relative national and international information about active power filters，the author put forward the idea of designing of active power filter based on simulators because current active power filters have the disadvantages of low temporal activity and low price performance ratio. The paper introduced in details on all kinds of current determining methods of active power filters, and analyzed stress on the instantaneous reactive power method, the author also designed a harmonic wave determination current of the simulation active power filters of ip－iq calculation，and other relative circuits such as PWM controlling circuit, driving circuit, and inversion main circuit etc. Under the circumstance of Matlab/Simulink simulation， the author works on setting model and simulation analysis of active power filters based on instantaneous reactive power theory, the result showed the validity and feasibility of the designing idea of simulative active power filters mentioned in the paper. Active power filters designed by using the method has good dynamic properties and determining accuracy，and they also have the advantages of low developmental cost and small size, they also have good modularization and integration characters.
