| 摘 要： | 瞬时无功功率理论在三相电路谐波和无功电流检测中得到了广泛的应用,该理论也适用于单相电路.对基于该理论的检测方法之一即构造两相电流分量的方法进行了详细的推导,针对现有方法中的不足进行改进,新增了单独的无功电流检测环节,并给出了准确获得各电流量的关键算法.在采用该检测方法的同时,将10个H桥级联的拓扑结构应用于单相APF,运用倍频载波移相调制技术和电流PI控制实现APF的功能.大量的仿真分析证明了提出的检测方法的正确性和有效性,APF接入系统后的仿真结果表明该装置能够很好地完成谐波及无功电流的补偿功能.

| Abstract: | The instantaneous reactive power theory has been widely used in harmonic and reactive current detection in three-phase system.It is also applicable for single-phase circuit.After a detailed analysis to the shortages in the existing method of constructing two-phase system based on the foregoing theory,some improvements were presented.A new channel for detecting reactive current was proposed and the key algorithm to obtain the important current components was presented too.With this detection method,the casca... |
