试论动态电压恢复器控制方法的改进

The Improvement of the Controlling Means for DVR

随着现代工业技术的发展，电网结构也变的日益复杂。许多的电力敏感设备被应用于生产，这些设备对用电质量的要求高，新的电能质量问题随之而来。文章主要介绍了DVR的主电路结构和工作原理，优化了传统的补偿策略，提出了基于干扰电压前馈校正的改进控制方法。

As the development of modern technology,the electric network frame has become more and more complex. A lot of sensitive electrical power units which are strict to power quality are applied in industry. Then follow the new power quality problem. This paper mostly introduces the main circuit frame and operational principle of DVR, optimizes the traditional compensation strategy, and puts forward the modified controlling means base on disturbance voltage feed forward emendation.
