Study of Input Voltage Anti-Disturbance Control of Matrix Converter Fed Induction Motor Drive System
Author(s): 
Pages: 47-52
Year: Issue:  10
Journal: Transactions of China Electrotechnical Society

Keyword:  矩阵式变换器输入电压跌落不平衡过调制;
Abstract: 详细分析了输入侧电压扰动(包括瞬时电压跌落、三相不平衡等)对矩阵式变换器驱动异步电机调速系统性能的影响,包括电机电压波动和电机转速跌落.提出了一种抑制输入电压扰动的控制策略,采用空间矢量过调制技术,扩大了系统的运行范围.仿真分析和实验结果表明,提出的抑制输入电压扰动的控制策略在输入电压跌落和不平衡两种情况下,均可有效地补偿矩阵式变换器输出电压,维持电机转速的恒定.从而增强了系统的抗扰动能力,提高了...
