Abstract

The invention provides a photovoltaic system power generation state monitoring method and its device. The method firstly determines a benchmark power station among the photovoltaic power stations that are all in the same area grid as the target power station and have realized remote monitoring; and then use the benchmark power station The power generation parameters of the target power station are used as a reference, and the theoretical value of the power generation state of the target power station is estimated by the preset algorithm, and compared with the actual value of the power generation state obtained by relying on the State Grid New Energy Cloud; and then without adding any additional hardware equipment , realize the effective evaluation of the power generation status of the target power station, solve the problem of low power generation management level of the power station caused by the lack of remote monitoring of most small and medium-sized household photovoltaic power generation systems, and the realization 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...
