摘要
比较目前电能质量检测仪器的优缺点,设计了基于虚拟仪器技术的电能质量监测系统。针对谐波检测中动态扰动的存在,采用了一种给予小波补偿的FFT算法来提高测量精度,同时运用LabVIEW中的DataSocket控件实现网络通信功能。通过仿真及实测验证了该系统的可行性。
In this paper, power quality monitoring system based on virtual instrument is designed after comparing several power quality monitoring instruments. A new FFT algorithm based on the wavelet transform reconstruction is used to reduce the errors caused by unstable disturbances. And network communication is achieved with Data-Socket controller. Simulation and application show that this system is reasonable and has good accuracy.
