| 摘要: |
| 考虑动态电压恢复器(DVR)在不同的补偿方式下对装置的能量要求不同,针对如何实现DVR最小能量补偿进行研究,将电压补偿情况分为7种(5种为电压暂降情况,2种为电压突升情况),并根据每种情况的各自幅值、相角特点,计算DVR输出的补偿电压的幅值和相角,并给出最小能量补偿的依据.同时,在DVR传统结构上进行改进,以最新的三单相独立补偿取代传统的三相同时补偿,形成3个独立的充电电路、储能电容和输出补偿电路,提高了DVR的响应速度和精度,而且增加了抑制电压突升的功能.在Matlab/Simulink仿真软件下进行的单相电压跌落补偿试验,仿真结果显示,所提的补偿算法在不同电压突变情况下,均可对系统进行恰当的电压补偿,并能保证DVR消耗的能量最小. |

| Abstract: |
| For DVR (Dynamic Voltage Restorer)requires different energy under different compensation modes,the compensation with minimal energy consumption is studied.There are seven voltage compensa- tion conditions:five for voltage dips and two for voltage surges.The output voltage amplitude and phase angle of DVR are calculated for these conditions respectively according to their particular conditions of vol- tage amplitude and phase angle,and the basis of compensation with minimal energy consumption is given. The t... |
