论文摘要
提出了一个能够显示住宅电压信号的相关功率质量数据的简单且廉价的系统，并基于Arduino，Python和Kivy。建议调整用于采样的电压信号的电路。该系统的软件允许使用任何能够以2000000 baud速率串行通信的设备传输数据，尽管建议使用基于Arduino Nano R3的Arduino Nano/Uno板。该软件绘制数据中数据中包含的最后6个周期默认情况下，但让我们分析任何数量的周期。它提供了RMS电压，峰值电压和审查循环的总谐波失真，直至第25个谐波。该软件还能够计算所研究周期的快速傅立叶变换，并返回相应的图。显示了委内瑞拉Maracaibo捕获的数据样本。
A simple and inexpensive system capable of displaying relevant power quality data of a residential voltage signal is presented, and it is based on Arduino, Python and Kivy. A circuit for adjusting the voltage signal for sampling is suggested. The software of the system allows the transmission of data with any device capable of serial communication at a 2000000 Baud rate, although an Arduino NANO/UNO board is recommended A board based on an Arduino NANO R3 was used. The software plots the last 6 cycles contained in the data by default, but lets analyze any amount of cycles. It provides the RMS voltage, the peak voltage and the total harmonic distortion of the scrutinized cycles, up to the 25th harmonic. The software is also capable of calculating the fast Fourier transform of the studied cycles, and returning the corresponding plot. A sample of data captured at Maracaibo, Venezuela is shown.
