Abstract

Under the energy shortage situation, photovoltaic grid-connected power system has broad development prospects and practical value. Photovoltaic power generation system connected to the grid will bring out the problems of bi-directional metering of electric energy and the change of the power quality. In response to these problems, the bi-directional electric energy metering and power quality analyzer is developed in this paper. Based on three-phase electric energy measurement chip ATT7022 and MCU, the bi-directional electric energy metering is implemented, and the measurement of voltage frequency. According to the sampling frequency of real-time frequency of voltage signal, the good harmonic analysis function is realized.
