摘要 目前随着电力电子技术的发展，越来越多的电力电子装置被制造和应用到电力系统的运行中去。由于大量电力电子设备以及其他非线性负载的接入，导致了电网中混有大量的谐波和间谐波，这些谐波给电力系统带来了严重的污染，并由此产生了一系列电能质量问题，严重危害了用电设备和通信系统的稳定运行，而各种敏感负载对电网的供电质量又提出了更高的要求。因而了解谐波产生的机理，研究和清除供配电系统中的高次谐波，对改善供电质量，确保电力系统安全，经济运行都有着十分重要的意义。
首先，论文论述了课题研究的背景，然后又对电能质量的基本概念及标准作了说明，并介绍了电能质量与电力系统谐波之间的关系。
其次，论文在电力系统谐波检测方面介绍了国内外常见的谐波检测方法，并着重介绍了基于瞬时无功功率的谐波检测方法。并依据他们各自性能的特点，分析了在电力系统谐波检测中集中方法的适用范围及优缺点。
然后，论文讨论了电力系统谐波常用的抑制方法：即基于改造谐波源本身的谐波抑制方法（主动治理）和基于谐波补偿装置功能的谐波抑制方法（被动治理），并对每种方法所采用的具体措施作了详细的探讨。并以并联型有源电力滤波器为例，采用瞬时无功功率理论的ip-iq算法，并借助MATLAB进行了仿真模型，并最后给出仿真结果，验证了该方法的有效性和结论的正确性。

The Study of Power Quality Control Technology
Abstract With the current development of power electronics technology, more and more power electronic devices are manufactured and applied to the operation of power systems go. Due to a large number of power electronic equipment and other non-linear load access, resulting in a large number of mixed grid harmonics and inter-harmonics, these harmonics to the power system caused serious pollution, and thus produced a series of energy quality problems, serious harm to the stable operation of electrical equipment and communications systems, and a variety of sensitive loads and for the quality of power supply put forward higher requirements. Thus understanding the mechanism of harmonic generation, supply and distribution system research and clear the higher harmonics, to improve the quality of power supply, ensure that the power system security and economic operation have a very important significance.
The paper first discusses the research background, then the basic concepts and standards of power quality are described and describes the relationship between power quality and power system harmonics.
The second part of the thesis in harmonic detection of power system are introduced the common method of harmonic detection ，and focuses on the harmonic detection method based on instantaneous reactive power. And based on their respective performance characteristics, analyzes focused on the power system harmonic detection method and scope advantages and disadvantages.
The third part of the thesis mainly discusses the power system harmonic suppression method based on commonly used: Transformation of harmonic source method for harmonic suppression (active management) and based on the harmonic compensation device function method for harmonic suppression (passive management) two kinds of main methods, and for each method are only some specific measures are introduced in detail. And case study of shunt active power filter, by using the ip-iq algorithm instantaneous reactive power theory, and with the MATLAB simulation model，the simulation results are given to verify the validity and correctness of the conclusions of the method.
