摘　　要：本文首先介绍了DVR的原理、结构,然后分析了多种常用信息检测方法的原理和优缺点,包括快速准确识别扰动的各种坐标变换法,及用于相位获取的软件锁相法。接着对常见的补偿策略进行了归纳和比较,详细介绍了目前广泛应用的最小能量补偿及其改进算法。最后对动态电压恢复器理论和实验研究进行了探讨。In this paper, the principle and topology of dynamic voltage restorer（DVR） are presented at first; then the principle of information detection methods in common use and their advantages and defects are analyzed, including various coordinate transformation methods for fast and accurate disturb identification, and soft phase locking method for phase acquisition. The induction and comparison of familiar compensation strategies are carried out, especially discussing the widely used minimum energy compensation with its improvement. Finally the development trend of the theory and experimental research of DVR are described.
