谐波电能提取利用技术的研究

Researches on Technique and Using of Extracting Harmonic Energy

研究了一种基于基波磁通补偿方法与调谐滤波技术相结合滤除并提取矿区电网中谐波电能的技术,并对其进行了理论推导。利用MATLAB建立了三相桥式整流电路仿真模型,对其稳态电路进行了仿真研究,并与传统滤波效果进行对比,证明了该理论的正确性。

A technique of extracting and using harmonic energy in power grid of coal mine area based on the principle of fundamental magnetic flux compensation and tuning filter technology is studied and analyzed. On top of this principle, the three-phase bridge rectification circuit is established, and steady-state characteristics are simulated and analyzed by MATLAB in the paper, comlared with the effects of the conventional filter harmonic, the principle is correct.
