Title:
POWER STATION OPERATION AND MAINTENANCE SYSTEM, POWER STATION OPERATION AND MAINTENANCE METHOD, AND PHOTOVOLTAIC POWER STATION
Document Type and Number:
WIPO Patent Application WO/2023/272479
Kind Code:
A1
Abstract:
The present application provides a power station operation and maintenance system, a power station operation and maintenance method, and a photovoltaic power station. A data processing system in the power station operation and maintenance system can determine a failed assembly and a normal assembly on the basis of assembly data of photovoltaic assemblies in a photovoltaic string, and obtain first power generation data of the failed assembly and second power generation data of the normal assembly. Furthermore, the data processing system can determine annual power generation loss of the failed assembly on the basis of the first power generation data, the second power generation data, and preset power generation of the photovoltaic power station, and obtain a target operation and maintenance measure from a plurality of operation and maintenance measures on the basis of the annual power generation loss. In this case, a communication system in the power station operation and maintenance system can instruct, on the basis of the target operation and maintenance measure, an operation and maintenance user of the photovoltaic power station to perform operation and maintenance on the failed assembly, so as to improve power generation. The present application can quantitatively analyze power generation loss of a failed assembly, improves the diversity of operation and maintenance measures and power generation of an assembly, and features low cost and high applicability.
