【摘要】 本课题主要研究电力电子负载侧谐波抑制解决方法，基本思想是装设谐波补偿装置。文中首先介绍了电网中存在的谐波问题、谐波的意义及研究现状，谐波的基本概念，同时就典型三相整流电路进行具体的分析。在谐波抑制方面，本文对当前研究的热点—串联和并联有源滤波器进行了理论分析，将电力有源滤波器控制分为两层结构，内层直接面向电力电子主回路，实现指令电流或是电压的跟踪。外层控制实现参考值的计算和直流电容电压控制。针对国内外大部分研究均集中在外层控制，而对于至关重要的内层跟踪控制研究甚少的情况，本文将SVPWM调制与无差拍控制技术引入有源滤波器内层跟踪控制中，对SVPWM调制与无差拍控制技术在有源滤波器中的应用进行了理论研究与仿真，仿真结果表明SVPWM调制与无差拍控制技术不但具有易于数字化的优点，而且在补偿性能和降低装置体积等方面均优于传统方法。在理论分析和仿真基础上，进一步分析了串联和并联电力有源滤波器的优缺点，并给出一种补偿功能较为完善的串并联混合型电力有源滤波器及其控制方法，通过仿真验证能很好弥补串联和并联有源滤波器各自缺点。更多还原

【Abstract】 This paper discussed the eliminated technique of the load humorous and power factor. A fund method is install a harmonic compensate equipment. At first this paper introduced the humorous problem in the electricity, and putting forward the nation of studying a harmonic meanings and the present condition. In the aspect of eliminated technique, this paper emphases to investigate the series active power filter and shunt series active power filter, dispart the series active power filter control into two-layer structure, the inner layer face the main loop to track the reference current or voltage. The outer layer computes the reference and keeps the capacitance voltage invariableness. Aim at the complexion of national research focus on the outer layer control, the paper introduce the Space Vector Pulse Width Modulate and deadbeat control into the active power filter’s inner layer control, and analyses its’ principium and simulate its’ controlled method. The result indicate the Space Vector Pulse Width Modulate and deadbeat control not only be prone to realize digital computer control, but also can excel the traditional method in the aspect of performance.In the base of analyses and simulation, discussed the shortcoming of the series active power filter and shunt series active power filter, and give the structure and control method of a integration of series and shunt active power filter, the simulation prove it can make up the shortcoming of the series active power filter and shunt series active power filter.更多还原
