动态电压恢复器补偿信号改进检测法

Improved Approach Based on Park-transform Used to Detect Compensating Signal of Dynamic Voltage Restorer

提出了一种基于派克变换的动态电压恢复器补偿信号的改进检测方法。该电压检测方法不需锁相环,具有较好的检测精度和动态响应速度。最后,通过Matlab仿真,验证了该电压检测方法的有效性,并对含有暂态分量的信号检测进行了仿真,表明该法对暂态分量的检测具有一定的功用。

An improved approach based on the Park-transform, which is used to detect compensating signal of dynamic voltage restorer, is presented in this paper. The new approach needs no phase locked loop （PLL）, and can achieve preferable precision and dynamic response velocity. The simulation result shows that the new approach can perform well in transient components detection.
