【摘要】 本文结合韶关冶炼厂2002年技改项目——韶冶工业电谐波治理工程，针对韶关冶炼厂供电系统的现状，利用原有的谐波监测、分析装置的分析结果，对我厂电网谐波进行综合治理。 论文首先介绍了谐波的基本概念、谐波的产生及其危害，阐述了谐波问题研究的必要性，并扼要介绍谐波抑制的方法；然后介绍了谐波分析法的基本原理，并对各种方法进行了比较；此外还介绍了谐波滤波的几种方法及其工作原理，并着重介绍了具有良好性能和应用前景的混合型有源滤波器的工作原理。 在此基础上，论文介绍了韶冶工业电谐波治理工程系统的硬件、软件设计，以及研制过程中的关键技术。利用该系统，对韶关冶炼厂电网的谐波进行了治理，通过实际投运结果表明：该系统滤波效果明显，具有良好的经济效益。更多还原

【Abstract】 The paper is concerned with the important project of Shaoguan smelting factory in 2002 - the power net harmonics elimination in Shaoguan smelting factory .According to the results obtained by the harmonics measurement device and the actuality analysis of the power net in our factory, we have taken appropriate measures to eliminate the harmonics.Firstly, this paper introduces the concept of harmonics and its harm to power grid. And it also demonstrates the necessity of eliminate harmonics, and briefly introduces several methods to eliminate harmonics.Secondly, it recommends the fundamental theories of harmonic analysis and the difference between those methods. And then introduces several methods of eliminating harmonics, and emphatically introduces the working principle of HAPF(Hybrid Active Power Filter) which have excellent performance and good application foreground.Finally this paper illustrates the key techniques used in the development of the system and the application results of the project, combining with the development of HAPF. The application results used in the power net shows that the system is very effective in eliminating harmonics and has achieved good economical results.更多还原
