Abstract

In recent years, the power grid and its load structure has undergone great changes. Especially the interference of a large number of non-linear and impact loads have caused voltage waveform distortion, voltage fluctuations, and a series of power quality problems. Therefore, extensive attention has been paid on the research of power quality on-line monitoring device. This paper focuses on the power quality monitoring device hardware, and designs a MCU system, which is based on C8051F340, as the device's handle control core. Then on this basis, we design sensor unit, sampling trigger unit, analog-to-digital conversion unit etc, and actually make and weld PCB. As for software, under the Keil Vision4 development circumstances, the author uses C language to develop MCU's control, computing, communication, and other programs of lower computer. Actual test results has proved the design’s rationality, and the installation’s various functions and indexes can meet the requirements of power quality online monitoring.
