| 摘 要： | 提出了区域型动态电压补偿器(Dynamic Voltage Restorer,DVR)的设计思想,介绍了该DVR的主电路拓扑、电压跌落检测算法、参考电压计算方法和脉冲调制方法。基于目标变电站及馈线下不同负荷类型,根据不同负荷类型对电压暂降的敏感性,提出了确定区域补偿型DVR接入位置的馈线选择原则,以某变电站为例说明了具体的选线方法。仿真分析了不同故障类型下DVR的补偿效果,验证了其设计的有效性和合理性。

| Abstract: | This paper proposes the designing of regional compensation Dynamic Voltage Restorer(DVR), and the topology of main circuit, the detection algorithm for voltage sag, the calculation method of reference voltage and pulse modulation method are introduced. Based on the different load types of the target substation and the sensitivity to voltage sags, the principle of the selection location of compensation line for regional compensation DVR is proposed, and the realization of substation line selection method is illustrated by taking a substation as an example. The compensation effect of the DVR under different fault types are simulated, and the validity and rationality of the designing are verified. |
