摘要
根据瞬时电压d-q分解法原理,利用Motorola DSP56F807研制出一台电压凹陷的检测装置,详细讨论了其硬件和软件的设计。在装置上完成对电压凹陷的检测,并通过选取不同截止频率的低通滤波器,达到不同的检测效果。实验结果证明该装置对电压凹陷的检测具有快速性和准确性。
Based on the instantaneous d-q transformation theory, a voltage sags detection device is developed by Motorola DSP56FS07. The hardware and software design are detailed. The detection of voltage sags is finished on the device. This paper designs a low-pass filter and analyses the results on the different cut-off frequencies. The results prove the device can detect sags quickly and accurately.
