基于LabVIEW的光伏微网实验系统设计

Design of photovoltaic microgrid system by LabVIEW

依据高校工程教育培养需求,搭建光伏微网实验硬件平台,采用LabVIEW、SQL Server为上位机软件平台,设计一套光伏微网实验系统。通过Modbus TCP通信协议实现硬件平台与LabVIEW上位机通信,使用ActiveX数据对象完成LabVIEW与数据库连接,增加用户权限管理完成不同用户实验设备和数据使用权限。实践证明实验系统为光伏微网研究提供可靠的数据支持,有较大的推广和实用价值,同时很好地满足高校工程教育需求和社会工程人才能力培养。

A laboratory-scale microgrid system was designed in this paper,according to the needs of engineering education.LabVIEW and SQL server were used as host computer software in the experimental system.The communication between hardware platform and LabVIEW host computer was realized by Modbus TCP communication protocol.The connection between LabVIEW and SQL was completed by using ActiveX data object.User rights management was added to complete different user's experimental equipment and data use rights.It is proved that the system provides reliable date support for the micro-grid research,which has great promotion and practical value.The system meets the needs of engineering education and social engineering talent training.
