与公用事业网络同步是运行三相并网变流器的关键。如何在失真和不平衡的条件下快速准确地提取基本的正负序列是同步的一个挑战。在过去的几十年里，人们提出了许多锁相环和同步技术。在严重失真和不平衡条件下，它们大多在精度和动态响应之间进行权衡。本文提出了一种基于多重复系数滤波器的锁相环，其独特之处在于能准确、快速地从受污染的电网电压中提取正、负序分量，并能精确地估计谐波分量，在有源滤波器的选择性补偿中具有潜在的应用价值。该方法的另一个优点是在某些特定条件下可以灵活地简化其结构。MATLAB连续域仿真和基于32b定点TMS320F2812 DSP的离散域实验结果吻合良好，验证了所提方法的有效性。
Synchronization with the utility networks is crucial for operating three-phase grid-interfaced converters. A challenge of synchronization is how to fast and precisely extract the fundamental positive and negative sequences under the distorted and unbalanced conditions. Many phase-locked loop (PLL) and synchronization techniques have been presented in the past decades. Most of them make a tradeoff between the accuracy and dynamic response under severe distorted and unbalanced conditions. In this paper, a multiple-complex coefficient-filter-based PLL is presented, and its unique feature lies in the accurate and rapid extraction of the positive and negative sequence components from the polluted grid voltage, and the harmonic components can also be estimated precisely, which has the potential use for selective compensation in active filter applications. Another advantage of the proposed method is its flexibility for simplifying its structure in some specified conditions. Results of continuous-domain simulations in MATLAB and discrete-domain experiments based on a 32-b fixed-point TMS320F2812 DSP are in good agreement, which confirm the effectiveness of the proposed method.
