Photovoltaic power station modeling method and device based on coding

Abstract

The present invention provides a photovoltaic power station modeling method and device based on coding. Data information of a photovoltaic power station device and a photovoltaic power station are employed to establish a discrete photovoltaic power station metadata in a coding mode, the photovoltaic power station metadata is employed to establish a primary device model and a communication data model, and a metadata coding rule is employed to map devices in the primary device model and devices in the communication data model. When a corresponding communication data model is introduced, the communication data model device measurement point types and the measurement point attributes can adaptively map the primary device model due to association of the primary device and the device measurementinformation and the communication data model. The primary device model data measurement points are taken as data sources to obtain the photovoltaic power station data model constructed at the initialstage of construction of the photovoltaic power station so as to solve the problem that a monitoring system is large in workload because the photovoltaic power station is established to perform debugging communication and the communication data model measurement points are mainly employed in the prior art and provide data for the photovoltaic power station power regulation model and the prediction model.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a coding-based photovoltaic power plant modeling method and device. Background technique [0002] According to the needs of sustainable economic and social development, the renewable energy-based energy structure will gradually replace the fossil energy-based energy structure. Among them, the construction of photovoltaic-based new energy power generation has been vigorously developed, and the annual installed capacity and grid-connected capacity are increasing significantly. [0003] However, there are many types of equipment in the photovoltaic power station system, and the number of equipment is relatively large. In the existing monitoring system, the routine basic monitoring is modeled in units of measurement points. For a 100MW photovoltaic power station, there are more than 100,000 measurement points for communication access, and more than...
