Abstract:

动态电压恢复器(dynamicvoltagerestorer,DVR)的响应速度是衡量DVR特性的重要指标,锁相环和电压跌落检测算法则是决定其响应速度的2个关键因素,而电网电压畸变、跌落过程中发生的相位跳变和电压不平衡制约着锁相环和检测算法的快速性。该文结合最小方差(leasterrorsquares,LES)滤波器和改进对称分量法设计了新的软件锁相环和电压跌落检测算法,对这2种方法进行详细的理论推导,阐明各频次的正负序分量解耦的机理。在Matlab/Simulink中搭建仿真模型,与传统锁相环方法和电压跌落检测算法进行对比分析。最后,在电压跌落平台进行工业样机验证,结果表明所提方法可行有效,且具有较高的响应速度。
