摘要
针对传统的检测方法存在计算量大、瞬时性差等缺点,采用自适应噪声抵消技术(ANCT)进行谐波和基波无功电流检测,并根据检测原理设计出检测电路.由于该方法具有计算量小、实现容易的特点,从而避免了采用其他方法进行大量计算带来的延时问题.仿真结果表明,采用ANCT技术响应速度快、检测精度高、自适应能力强.
The traditional methods of harmonic detection have some disadvantages, such as the large calculation, instantaneous prolongation. To avoid those disadvantages, the method of harmonic and fundamental reactive current detection was adopted. It was also called adaptive noise canceling technology （ ANCT ） . Circuit was designed according to principle of harmonic detection. The method has the characters of brief calculation, easy realization and able to avoid delay caused by the large complexity of calculation. The simulation results show that this detection method which is based on ANCT technology has the faster dynamic response, the higher detecting precision and the better adaptive following detecting ability.
