摘要
以“负载电流为周期电流时,负载电流与负载基波有功电流差的绝对值在一个周期内的积分值最小”为检测原理,提出了一种基于迭代算法的有源电力滤波器单相电路谐波电流检测方法。该方法能够快速跟踪负载基波有功电流幅值,特别是当负载电流发生突然变化时。
Using “when load current is periodic function,the integral value in a period for ahsolute value of load current subtracting fundamental active current is the least” as detecting principle, a detecting approach of harmonic current in single-phase circuit based on fast iterative algorithm in active power filter was proposed. It is capable of fast tracking load fundamental active current maximum value aad especially the maximum value when load current takes a abrupt change. The correctness of the method was verified by theoretical analysis and simulation research. This project is supported by High-tech Item of Jiangsu Province（ No. GB2004024） and Dedicated fund for Higher Intellectuals of Jiangsu University （ No. 1283000064 ）.
