| 摘 要： | 为了充分发挥固态切换开关(SSTS)容量大和动态电压恢复器(DVR)响应迅速的优点,本文通过一种结合单相dq变换和形态学滤波器的单相电压跌落检测方法精确检测单相电压暂降,在此基础上提出一种基于电压跌落等级划分与时序配合的DVR与SSTS协调控制方法,实现了DVR和SSTS的协调动作,保障了敏感负荷的持续高质量供电。基于Matlab/Simulink的仿真模型验证了该协调控制策略的正确性和有效性。

| Abstract: | In order to give full play to the large capacity of SSTS and the rapid response of DVR,a single-phase voltage sag detection method based on single-phase dq transform and morphological filter is presented in this paper.The DVR and the SSTS coordinated control method are combined with the DVR and the SSTS to achieve the coordinated action of the DVR and the SSTS,thus ensuring the continuous high quality power supply of the sensitive load.The simulation model based on Matlab/Simulink verifies the correctness and validity of the proposed control strategy. |
