Description

technical field [0001] The invention belongs to the field of monitoring, diagnosis and operation and maintenance of the whole life cycle of a photovoltaic power station, and is specifically a system for collecting main performance parameters of a solar power station and intelligently processing the parameters. Background technique [0002] Solar photovoltaic power station is a new green and environment-friendly power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. Usually solar photovoltaic power plants include solar panel arrays, combiner boxes, low-voltage power distribution cabinets, grid-connected photovoltaic inverters, AC power distribution cabinets, transformers and other components to achieve grid-connected power generation in a straight line. [0003] In order to ensure the normal operation of the solar photovoltaic power station, a monitoring system is used ...

AI Technical Summary

Problems solved by technology

[0004] 1. The appeal plan has not disclosed the unified management of power station data monitoring, video monitoring, operation and maintenance management, and asset management subsystems to realize the linkage between multiple systems. The huge operation and maintenance workload has caused failures to be handled in time, Reduce the efficiency of the system and increase the management cost of the system;

[0005] 2. The above scheme does not provide an expert database for fault diagnosis, but only introduces the countermeasures it can provide in general, and does not come up with specific implementable schemes;

[0006] 3. The above scheme cannot automatically locate and open the video monitoring module in the corresponding area after the power station equipment fails to observe the actual situation on the site; it cannot automatically locate the actual physical location of the faulty equipment to facilitate the maintenance personnel to detect and replace the on-site equipment;

[0007] 4. The above scheme cannot realize that when the power station equipment fails and needs to be repaired, the inventory and model of spare parts in different regions can be automatically retrieved to facilitate the rational allocation of overall resources
