摘要
根据离散傅立叶变换原理,计算出基波有功电流幅值,从而计算出需要补偿的谐波和无功电流。该方法具有计算量非常小、实时性好、检测精度高等特点,是一种具有应用前景的有源电力滤波器单相电路谐波电流实时检测方法。
According to DFT principle,the fundamental active current maximum value can be calculated and the compensation harmonic and reactive currents can also be calculated,it has the characteristics of very little calculation capacity,nice real time performance and high measurement precision and so on. It is a real-time detection method for single-phase harmonic and reactive currents in active power filter to have applying outlook.
