本文介绍了一种新的自适应陷波滤波（ANF）方法作为一个强大的工具，单相变流器接口DG系统的同步。该技术简单，能够提取谐波，跟踪幅值和频率变化，并提供电网信号的相位角。该方法适用于广泛的设备，如转换器接口的分布式发电（DG）单元，例如风力，光伏，燃料电池和微型涡轮机，以及有源电力滤波器和不间断电源。理论分析和性能的方法进行了评估，通过仿真和实验工作。
This paper introduces a new adaptive notch filtering (ANF) approach as a powerful tool for synchronization of the single-phase converter-interfaced DG systems. The technique is simple and capable of extracting harmonics, tracking the amplitude and frequency variations, and providing the phase angle of the grid signal. The methodology is applicable for a wide range of equipment like converter- interfaced distributed generation (DG) units, e.g. wind, photovoltaic, fuel cells and micro-turbines, and also in active power filters and uninterrupted power supplies. Theoretical analysis is presented and the performance of the method is evaluated through simulation and experimental work.
