Abstract

The application provides a distributed photovoltaic power station fault monitoring method and device based on edge computing, which are applied to an edge computing device. The method comprises the steps of: obtaining meteorological and environmental parameters of an area where a target distributed photovoltaic power station is located, cloud block image data and field equipment image data above the target distributed photovoltaic power station; predicting the power generation power of the target distributed photovoltaic power station in a set time period by using the meteorological and environmental parameters, the cloud block image data above and the field equipment image data to serve as predicted power generation power; acquiring actual power generation power of the target distributedphotovoltaic power station within the set time period; and monitoring whether the target distributed photovoltaic power station has abnormity or faults or not by comparing the predicted power generation power with the actual power generation power. In the application, the abnormity or fault monitoring of the target distributed photovoltaic power station can be achieved through the mode, and the monitoring reliability is improved.

Description

technical field [0001] The present application relates to the field of power electronics technology, and in particular to a distributed photovoltaic power station fault monitoring method and device based on edge computing. Background technique [0002] Because fossil energy is non-renewable and its consumption pollutes the environment, countries are paying more and more attention to the development and utilization of new energy, especially solar energy, which has no geographical restrictions, is renewable, and has no pollution. In recent years, with the rapid development of the photovoltaic industry, the use of distributed photovoltaic power plants has increased. [0003] However, how to monitor whether abnormalities or failures occur in distributed photovoltaic power plants has become a problem. Contents of the invention [0004] In order to solve the above technical problems, the embodiments of the present application provide a method and device for fault monitoring of ...
