摘要
提出了一种从电力系统信号中提取基波的计算方法．分析了全周波富氏算法的特性、频率波动对富氏算法的影响及抑制富氏算法“泄漏”效应的数学方法，并用补偿法对计算结果进行修正，有效地提高了系统的响应速度和计算精度。
This paper presents a computing method of extracting fundamental wave from electrical POwer system's signal. It analyzes the characteristic of full cycle Fourier algorithm. The influence on Fourier algorithm because of frequency flutter and the mathematical method of suppressing leakage effect. Moreover, it uses compensation method to correct the computing results and increases the system's response speed and computing precision effectively.
