Abstract

This paper details the design and implementation of a photovoltaic current - voltage (I-V) tracer. The I-V tracer employs a capacitive load controlled by a raspberry pi model 4B. The complete measurement system includes protections, capacitor charging/discharging power electronics and current, voltage, irradiance and temperature sensors. Results, which include maximum power point, open circuit voltage, short circuit current and module efficiency, are displayed on an LCD touch display. Detailed description of the required software and the graphical user interface is also presented. This measurement system is very useful for testing photovoltaic installations, allowing an immediate verification whether the panels fulfill with the specifications and detection of possible failures.

摘要

本文详细介绍了一种光伏电流-电压（I-V）跟踪器的设计与实现。该I-V跟踪器采用由树莓派4B型号控制的电容性负载。完整的测量系统包括保护装置、电容器充电/放电电力电子设备以及电流、电压、辐照度和温度传感器。测量结果，包括最大功率点、开路电压、短路电流和模块效率，会显示在液晶触摸显示屏上。文中还给出了所需软件和图形用户界面的详细描述。该测量系统对于测试光伏装置非常有用，能够立即验证面板是否符合规格，并检测可能出现的故障。
