Abstract
First the paper expounds power quality problems in power grid. According to the characteristics of the steady state component and the transient component, DSP + ARM structure of electric power quality monitor system is designed. Then the paper mainly introduces the signal acquisition (DSP) part of hardware design: The hardware design includes the voltage signal acquisition, Antioxidant aliasing filter circuit design, A/D circuit design, phase-locked frequency circuit design; Finally power quality monitor system is applied in engineering field. Through a period of time to the monitoring data of test analysis found that new power quality monitor can be good to complete the design requirements, the desired effect for users to fully understand the site electrical energy environment provides scientific data.
