Summary:In this article, we introduce a set of online power quality monitor who is based on DSP (Digital Signal Processor). The monitor makes full use of DSP chip's strong operation capability. It can monitor power quality online, display real-time measure data and save super scalar data, which can provide accurate data to power quality evaluation and improvement. On the hardware side, the system takes DSP and CPLD as core of power parameter detection circuit, and complex programmable logic device (CPLD) and phase-locked loop (PLL) as synchronous sampling circuit, TO the software, designed relative software arithmetic. At the same time, the main program of electric power parameter detection was introduced. Experiments show the proposed system is of fast response, high accuracy, and real-time processing.
