| 摘 要： | 提出了一种三相三线系统动态电压调节器(DVR)的单周控制模型,把单周控制技术应用于DVR的控制中。在对主电路分析的基础上,导出了DVR的单周控制模型,并对电压暂降、暂升等情况进行了仿真实验分析。结果表明,单周控制用于DVR有较好的控制补偿作用,并兼有控制电路简单、动态响应好、实现方便等特点。单周控制用于DVR是一种可行的方案。

| Abstract: | A new one-cycle control scheme is proposed for dynamic voltage regulator in three-phase three-wires system,in this paper. One-cycle control is first used to DVR. The control model is given based on the analysis of main power circuit. And then conditions with voltage sagging to 65% of normal voltage and a voltage jumping up to 135% of normal voltage are simulated. The simulation results show that DVR with one-cycle control has a good compensating and control performance for voltage alternation limit in 35%. One-cycle control DVR has better dynamic performance,simply-controlled circuit and more convenient realization way. One-cycle control DVR is a feasible control scheme.
