摘要
为消除三相不对称系统中传统检测方法对谐波电流检测造成的误差,在此基于对瞬时对称分量法研究的基础上,结合二阶广义积分原理,对瞬时对称分量法进行了改进,提出了一种能够在三相不对称系统中对谐波电流信号实现快速、准确检测的方法。实验结果表明,基于该检测方法的有源电力滤波器(APF)能够有效地检测和补偿三相不对称系统中的谐波电流。
The detective method of harmonic is very important for APF.In order to eliminate the harmonic detection er- ror caused by asymmetry of three-phase voltage, an improved harmonic current detective method is proposed.The pro- posed method is based on the research of the instantaneous symmetrical components combining with the second-order generalized integrator.The experimental results verify that the active power fdter（APF） based on the detective method,can effectively detect and compensate harmonic current in three-phase asymmetrical system, and improve current waveform.
