Accurate measurement of power quality and rational analysis on the grid are the foundation of governance and compensation, it is also the key to solve power quality problem. This article designs one kind of power quality analyzer based on the FFT algorithm, take ARM+FPGA as the core of the hardware platform, uses the software and hardware coordination design, makes the system to be advantageous for the debugging and the revision. The system volume is small, low-power consumption. Through a low-voltage inverter system output voltage waveforms and harmonic measurement, the results showed that the system can be fast, high-precision, high-reliability to detect and analyze power quality.
