Distributed photovoltaic power station monitoring system based on virtual and real data fusion

The embodiment of the invention provides a distributed photovoltaic power station monitoring system based on virtual and real data fusion. The distributed photovoltaic power station monitoring system comprises a plurality of data sensors, a virtual-real fusion data subsystem, a digital domain, a communication interface and protocol conversion unit, the communication interface and protocol conversion unit is used for data communication among a physical domain, the virtual-real fusion data subsystem and the digital domain, and a data uplink information channel and a data downlink instruction channel are communicated; physical data and information data of each physical device of the distributed photovoltaic power station are collected through the virtual-real fusion data subsystem, so that the operation state synchronization of the physical model of the digital domain and each physical device of the distributed photovoltaic power station is realized. And fault analysis and control are realized through other mode
