Description

technical field [0001] The invention belongs to the monitoring technology of solar photovoltaic power grid, and in particular relates to a solar photovoltaic monitoring system based on the Internet of Things. Background technique [0002] The Internet of Things, an important part of the new generation of information technology, is also an important stage of development in the "informationization" era. It is widely used in the fusion of networks through communication perception technologies such as intelligent perception, identification technology and general computing. The Internet of Things architecture can be divided into three layers: perception layer, network layer and application layer. Through the combination of sensors and intelligent processing, the use of various intelligent technologies such as cloud computing and pattern recognition can expand its application fields and meet the needs of different users. [0003] Solar energy is an extremely abundant, clean and n...

Problems solved by technology

At present, solar photovoltaic systems are being vigorously developed all over the world, but due to the characteristics of fluctuations, intermittent, mismatching phenomena, and nonlinearity of system output in solar photovoltaic systems, it is necessary to develop a solar photovoltaic monitoring system to monitor system parameters. Real-time monitoring and analysis

The existing monitoring system can monitor the solar photovoltaic system in real time, but this system only obtains the corresponding monitoring data, and does not perform performance analysis, fault diagnosis, trend analysis and other functions on the system. To obtain system information, at the same time, the government, system integrators, suppliers and other departments cannot obtain information in a timely and synchronous manner, resulting in waste of data resources and cannot be used reasonably
