Abstract

The invention provides a photovoltaic system power generation state monitoring method and device, and the method comprises the steps: firstly determining a benchmarking power station in all photovoltaic power stations which are located in the same region grid as a target power station and achieve the remote monitoring; taking the power generation parameter of the benchmarking power station as a reference, estimating to obtain a power generation state theoretical value of the target power station through a preset algorithm, and comparing the power generation state theoretical value with a powergeneration state actual value obtained by relying on the state grid new energy cloud, so that on the premise of not additionally adding any hardware equipment, the power generation state of the target power station is effectively evaluated, the problem that the power generation management level of the power station is low due to the fact that most small and medium-sized household photovoltaic power generation systems lack remote monitoring is solved, and the implementation cost is low.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a method and device for monitoring the power generation status of a photovoltaic system. Background technique [0002] Nowadays, due to the advantages of clean, environmentally friendly, sustainable and short construction period, photovoltaic power generation has shown a leap in quantity and quality. In the future, it may gradually replace traditional energy and develop into the mainstream of grid power. With the continuous expansion of photovoltaic grid-connected scale, how to improve the power generation efficiency of photovoltaic power plants and reduce the operation and maintenance costs of photovoltaic power plants has become a crucial issue in the industry. [0003] For photovoltaic power plants, fault monitoring based on the monitoring system is currently the most widely used and most effective fault diagnosis method. At present, most ground-based cen...
