摘要
对谐波电流快速检测和跟踪的能力是有源电力滤波器补偿性能好坏的关键,为了能快速有效的检测出三相四线制系统中的谐波电流,本文在介绍传统FBD法的理论原理的基础上提出了一种改进的FBD法。它是将传统的FBD法经过一次线性变换,减少了其间的矩阵运算。该方法不受系统电压畸变的影响,可以明显减少原方法的计算量。理论分析和仿真以及实验结果证实了该方法的正确性和优越性。
This paper issues a kind of improved FBD.method based on traditional FBD method in order to detect harmonic current rapidly and efficiently in three phases four wires system because the ability of harmonic current detection and compensation is the key parameter of the Active Power Filter（APF）. The method is improved by a linear transformation so that matrix operation is reduced. The new method is influenced little by voltage distortion. The analysis, simulation and experiment have proved the correctness and its priority.
