|
摘要
有源电力滤波器(Active Power Filter—APF)可以对电网和负载的谐波和无功电流进行综合的补偿,因此成为解决无功和谐波的重要手段之一而受到关注。在有源电力滤波器的实现过程中如何实时准确的检测谐波和无功电流,以及如何得到最好的控制策略,成为了这一领域的研究热点。
本文首先对谐波产生的原因及其造成的危害做了概括性的论述和总结,继而对传统的瞬时无功功率理论的产生和基本原理做出了详细的论述,在此基础之上,通过对有源电力滤波器的工作原理工作特性的分析,提出了通过电压反馈技术实现谐波和无功电流检测方法。
本文对这一检测方法的基本原理和理论推导做了详细的阐述,并通过仿真和实验将电压反馈技术的谐波和无功电流检测方法,与瞬时无功功率理论在有源电力滤波器中的应用进行了对比。
结果表明电压反馈技术的谐波和无功电流检测方法检测谐波和无功电流,可以得到与瞬时无功功率理论同样的计算结果,但更加简单、无延时,这一结果奠定了该方法在实际应用中的基础。
在文章中还对这种算法的实现方法进行了论述,并使用TI公司的DSP2407作为控制器进行软件的编程,同时进行了主电路,检测电路,驱动电路等硬件的设计实现。
Active Power Filter-APF can compensate the harmonic wave and reactive current that is from power network and load. So APF has become one of important method to solve the harmonic wave and reactive current problem, and a lot of country have attend it’s development. To realize the compensation of harmonic wave and reactive current with APF, the research hot point is how to detect harmonic wave and reactive current quickly and accurately, and to use good control method.
First of all, This thesis analyze the reason of harmonic wave producing, and introduce the instantaneous reactive power theory. After analyze the APF working principle, the thesis bring up a way to detect harmonic wave and reactive current that is use voltage feedback to detect harmonic wave and reactive current.
There is the introducing of basic principle of the detecting way in this thesis. Through simulation we can know it have the same calculation result with that be counted by instantaneous reactive power theory, But it is so simple and quick, that can be use as a real time arithmetic.
It is more suitable to realize the APF system. The thesis also designed and realized the hardware and software of APF with DSP2407.
