Application of Low Cost Status Monitoring Method Based on Photovoltaic Power Generation Model
A photovoltaic power generation model was reasonably established through comparing with several monitoring methods,and comparisons were conducted between the photovoltaic power generation per unit area of actual equipment and model,so as to verify whether the established photovoltaic power generation model can realize the status monitoring of photovoltaic power generation equipment with low cost.The abnormal photovoltaic power generation equipment is visually detected from the status monitoring results in the first practical application.Following problems have been solved during analysing and treatment process,such as the string fault caused by hot spots,power limitation caused by unreasonable string connection,and abnormal fluctuation caused by condensation cloud covering.Finally,it is confirmed that this method could indeed be implemented with low cost and demonstrate a certain level of effectiveness.
