摘要
配电系统电压跌落时,动态电压恢复器(DVR)可以维持敏感负荷侧的电压稳定。介绍了级联动态电压恢复器(IDVR)的结构,在分析比较DVR和IDVR补偿策略的基础上,提出了一种新的最优容量选择方法,并通过仿真实验,证明该方法在跌落系数相同的情况下可大大减少IDVR系统容量,具有很高的实用性和可行性。
In distribution systems,the voltage stability at voltage-sensitive load side can be maintained by dynamic voltage restorer(DVR) while voltage sags occurs.It presents the structure of interline voltage restorer(IDVR),and compares the compensation strategy of DVR and IDVR,and designs strategy for optimizing the total rating of an interline dynamic voltage restorer (IDVR).Simulation is proceeded to verify the method,at the same simulation of sag factor,the total rating of IDVR is greatly reduced.The simulation result show the practicability and feasibility of this strategy.
