The Research And Development Of Distributed Photovoltaic Power Station Monitoring And Energy Efficiency Analysis System

Energy shortage and environmental pollution are becoming more and more serious, which has promoted the development and utilization of renewable clean energy. Due to the considerable economic benefits and environmental benefits of solar photovoltaic power generation, the solar energy industry has ushered in new opportunities for development in recent years. Our country is rich in solar energy resources, but due to environmental pollution and energy issues need to be resolved, the state is gradually increasing its investment in the construction of photovoltaic power plants. Photovoltaic power plants are divided into two kinds of centralized photovoltaic power plants and distributed photovoltaic power plants, in recent years, the proportion of distributed photovoltaic power plants gradually increased. In order to ensure the safe and efficient operation of the distributed photovoltaic power plant and the need to control the power grid, the power of the photovoltaic power station and the power of the various devices are required.On the basis of in-depth study on the monitoring technology and energy efficiency analysis of photovoltaic power plant, the paper presents the system structure and implementation scheme of distributed photovoltaic power station monitoring and energy efficiency analysis system. The whole system is divided into three levels:data acquisition layer, data processing and transmission layer, data display and analysis layer. Data acquisition layer uses DTU GPRS module to collect data and analyze the heterogeneous data. Data processing and transport layer uses WebService technology to achieve real-time equipment status and power generation data processing and transmission. Data display and analysis layer is used for power generation efficiency calculation model for power plant. Finally, the development of distributed photovoltaic power station and energy efficiency analysis system based on SSH framework is completed by using the information fusion technology.In this paper, the software system has the functions of real-time data acquisition, production and operation management, real-time monitoring of equipment, historical data analysis and power generation efficiency calculation and analysis. At present, has been in Xinjiang. Tianjin and other places on the line running. The practical application shows that the system can provide a great help to the intelligent management and maintenance of the power plant. It can improve the operation efficiency of power plant operation and maintenance management.
