Energy is the cornerstone of the existence and development of modern society. The energy consumption continues to increase, and the ensuing environmental pollution and increasing lack of traditional energy sources have also become the world's most concerned issues. The emergence of new energy has eased the current unfavorable situation. Among them, distributed photovoltaic (PV) power generation has been favored because of its abundant resources and no geographical restrictions. However, due to the scattered construction of solar PV power stations, it is not easy to manage. Therefore, research and development of PV remote monitoring systems for unified monitoring and management of PV power stations. In addition, the problem of solar cell output efficiency is also an important reason that restricts the utilization of solar energy. Improving the output efficiency of the battery based on the existing solar cell conversion efficiency is also a focus of current research. Based on the above background, the research content of this article is the network communication monitoring system for distributed PV power generation systems. This article first conducts the overall design of the PV remote monitoring system, constructs the system's distributed design structure, and divides the underlying hardware part of the system into control modules and transmission. According to the application requirements, the STM32 series single-chip microcomputer is selected as the controller of the system control module and the transmission module. The hardware circuit design and software process implementation of the system are studied to realize the data collection, MPPT control, and remote data transmission of the photovoltaic system. Features: Finally, through experimental simulation, it was verified that the light intensity increased from 600 to 800 W/m², and the output current of the inverter increased accordingly. The output current of the distributed PV power generation system was directly proportional to the change of the light intensity. The designed system is feasible.

分布式光伏发电系统网络通信监控系统

能源是现代社会存在和发展的基石。能源消耗不断增加，随之而来的环境污染和传统能源日益缺乏也成为世界最关心的问题。新能源的出现缓解了当前的不利局面。其中，分布式光伏（PV）发电因其资源丰富、不受地域限制而受到青睐。但是，由于太阳能光伏电站建设分散，管理起来并不容易。因此，研发光伏远程监控系统，对光伏电站进行统一监控和管理。此外，太阳能电池的输出效率问题也是制约太阳能利用的重要原因。在现有太阳能电池转换效率的基础上提高电池的输出效率也是当前研究的重点。基于以上背景，本文的研究内容是分布式光伏发电系统的网络通信监控系统。本文首先对光伏远程监控系统进行了整体设计，构建了系统的分布式设计结构，将系统底层硬件部分分为控制模块和传输部分。根据应用需求，选择STM32系列单片机作为系统控制模块和传输模块的控制器。研究了系统的硬件电路设计和软件过程实现，实现了数据采集、MPPT控制、以及光伏系统的远程数据传输。特点：最后通过实验模拟，验证光强从600增加到800W/m²，逆变器的输出电流相应增加。分布式光伏发电系统的输出电流与光照强度的变化成正比。所设计的系统是可行的。
