A health assessment method of photovoltaic power generation system based on variable weight analytic hierarchy process

The invention discloses a health state assessment method of a photovoltaic power generation system based on a variable weight analytic hierarchy process. This method takes photovoltaic power generation system as the evaluation object, studies and utilizes the real-time data collected from photovoltaic power generation system, adopts the non-linear fuzzy dimensionless data processing method and variable weight analytic hierarchy process strategy, and carries on the real-time assessment to the health status of photovoltaic power generation system. The method can evaluate the health status of thephotovoltaic power generation system in real time, realize the scientific fault early warning, thereby effectively improving the health management of the photovoltaic power generation system, therebyimproving the power generation efficiency and reducing the maintenance cost. 本发明公开了种基于变权层次分析法的光伏发电系统健康状态评估方法。该方法以光伏发电系统为评估对象，研究利用光伏发电系统中采集到的实时数据，采取非线性模糊无量纲化数据处理方法和变权层次分析策略相结合，对光伏发电系统的健康状况进行实时评估。本方法能够对光伏发电系统的健康状况进行实时评估，实现科学的故障
