Design The Monitoring System Of Photovoltaic Plant Based On LabVIEW

Environmental parameters, photovoltaic cells and inverters parameters for real-time monitoring, not only beneficial to the entire 3k W photovoltaic power plants remain at high efficiency working condition, but also the operation and management of the photovoltaic power plant staff more convenient and intelligent of. In order to better achieve the above functions, the subject of the theoretical and practical aspects, discusses a technique based on virtual instrument highly versatile, cost-effective and easy to operate solar photovoltaic power plant monitoring system design.After using the full text of the overall framework of the overall structure of the total score,by the current domestic and international PV power plant development and monitoring system to do in-depth technical studies and adequate market research, discussion and basically established the overall design of the system, to be adopted architecture PC and the next crew combined with each other to explore the real-time monitoring program related operating parameters. Then a detailed analysis of the monitoring system hardware design, hardware based on ARM machines mainly lower six parameters acquisition module, acquisition circuit consists of sensors, control chips and other electronic components and parts, we need to meet the data acquisition, data processing, serial communication and data transfer functions. Then discuss the software design system software is mainly based PC monitoring platform programming environment and programming language of Lab VIEW, and be among its main function is to achieve real-time display monitored parameters, process the relevant monitoring data as well as the next crewcontrol and communicate with each other. Communication between the upper and lower computer using RS485 bus to RS232 serial communication bus.Finally, the article discusses the process of final production and commissioning of photovoltaic monitoring system, a series of problems encountered in debugging conducted in-depth analysis, we summarized the findings of this study, and for deficiencies and need to be perfected the system proposed recommendations for improvement and prospects.
