摘要:

动态电压恢复器被认为是目前解决电压骤降等电能质量问题的有效装置之一。目前DVR的控制策略包括前馈控制、补偿电压反馈控制和复合控制策略等。文中对DVR的基本结构和工作原理进行了介绍,阐述了电压跌落的检测方法,分析了动态电压恢复器(DVR)的3种控制策略,以及3种控制策略的优缺点,通过建立了DVR的数学模型,仿真分析验证了DVR的可行性和有效性。

关键词: 动态电压恢复器, 控制策略, 前馈控制, 复合控制

Abstract:

Dynamic voltage restorer is considered to be one of the effective means to solve power quality problems such as voltage sag.DVR control strategies include feedforward control,compensation voltage feedback control and composite control strategy.The basic structure and working principle of the DVR on the voltage drop detection methods are introduced,the dynamic voltage restorer (DVR) control strategy is analysed,and the advantages and disadvantages of the three control strategies are pointed out.A DVR mathematical model is established and simulation verifies the feasibility and effectiveness of the DVR.

Key words: dynamic voltage restorer;control strategy;feedforward control;composite control
