Abstract The existing power quality monitoring devices are poor in versatility and compatibility, and are hard to upgrade. This article describes a intelligent power quality monitoring device based on IEC 61850. The device is compatible with digital and analog sampling,and achieves functions dispersedly. The device uses high-speed data bus for real-time data exchange between the plug-ins, and application functions are modularly, standardized and reusable, and management procedure is used to ensure that multiple boards work efficiently and orderly. The rotation vector method to improve the measurement accuracy of the frequency,and the optimized FFT algorithm based on hardware accelerator to ensure real-time large-scale data processing, and the improved wavelet denoising algorithm eliminates noise affect Effectively. Practice has proved that, the device meets the new demand for power quality monitoring in the context of digital and smart grid.
