【摘要】 本文首先讨论了谐波及无功电流传统检测方法的不足。根据自适应于扰对消的原理,提出了一种谐波及无功电流的自适应检测方法。设计并实现了基于该方法的检测系统,同时给出了实验结果,结果证实了文中所提出的方法的可行性。为有源电力滤波器、静止无功补偿器等动态补偿设备提供了一种谐波及无功电流实时检测的新方法。更多还原

【Abstract】 This paper first discusses limitations of the conventional detecting methods for the harmonic and reactive currents, Based on adaptive interference canceling theory, an adaptive detecting method for the harmonic and reactive currents is presented, A detecting system based on this method is developed, and test results are given which verify the feasibility of the method proposed by this paper, A new real time detecting method for harmonic and reactive currents is provided for the dynamic compensation equipments such as active power filter, static var compensator and so on.更多还原
