| 摘 要： | 提出了一种在电网电流畸变情况下依然适用的、基于FFT,IIR滤波算法的电网电流基波分量的实时检测方法。并用MATLAB和devpp进行了验证。理论分析表明:即使在电网电流剧烈变化时,这种方法仍然可以正常工作。该方法已应用在电力系统功率因数调节仪的研制中,用于计算电流基波。调节仪使用芯片ATmege128进行数据处理。结果证明了该方法的有效性和在工业应用中的适用性。

| Abstract: | A new way to real time detect the fundamental component of line current is presented,which is based on the FFT and IIR filtering arithmetic and suitable to the case in which there could be aberration in the line current. It is validated by the tools ofMatLab and devpp. Theoretical analysis is carried out to prove the fact that the method also valid even if the line current is inchanging violently. This method is already used for developing the power factor regulator in power system, and for calculating thecurrent fundamental component.The MCUchipATmege128 is used for data processingofthisregulator.Thevalidityandusefulnessin industryapplications of the method have been demonstratedalready. |
