Measurement and Control Platform of Micro Grid PV System Based on Cloud Monitoring Technology

为满足在线检测微电网光伏系统运行参数和大数据视野下的数据分析的需求,搭建了基于云监控技术的微电网光伏系统测控平台。该平台在不改变传统逆变器电路的情况下,加装了Wi Fi模块,运行自主设计的通信协议(包括Wi Fi模块与云服务器的通信协议、Wi Fi模块与逆变器的485通信协议),使逆变器、云服务器和移动设备之间可协同工作。实例验证发现,利用该平台,可实现云服务器对光伏系统运行状态参数的收集,并能支持手机移动端APP对相关参数的实时查询和控制指令的下达。结果显示,该平台可以有效监控光伏系统的工作状态,具有较好的工程实用性。

In order to meet the needs of online detection for the running parameters of micro grid photovoltaic system and performing data analysis in the view of big data, a micro grid photovoltaic system measurement and control platform based on cloud monitoring technology was built. The platform was attached a WiFi module without changing the circuit of classical in- vertor, and run self designed communication protocols, in which the communication protocol between the WiFi module and the cloud server together with the 485 communication protocol between the WiFi module and the invertor were included, that enable the inverter, cloud server and mobile devices to work together. Finally, it was verified by the experiment sample that the platform could be engaged to collect running parameters of the photovohaic system, and support real-time query for the relative parameters and control instructions which were issued by a mobile app. The results indicated that the platform could effectively monitor the working status of the PV system, and had a good practicability in engineering.
