Abstract

The invention discloses a photovoltaic power station state diagnosis method and device. The method comprises the following steps of: collecting panoramic data of a photovoltaic power station; extracting monitoring key data of the photovoltaic power station, and calculating an operation state index of the photovoltaic power station; establishing a normal cloud model according to historical data forthe operation state index of the photovoltaic power station, and calculating an abnormal threshold according to the cloud model; and finally, comparing the state index of the real-time monitoring data with an abnormal threshold value, and determining whether the real-time state is abnormal or not. According to the invention, the problem of large error rate caused by distinguishing and distinguishing according to subjective expectation of people in the traditional state evaluation technology of the photovoltaic power station can be solved.

Description

[0001] This application is a divisional application of the following application, the filing date of the original application: November 03, 2016, the application number of the original application: 201610972757.6, and the invention title of the original application: a method and device for diagnosing the state of a photovoltaic power station. technical field [0002] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a method and device for diagnosing the state of a photovoltaic power station. Background technique [0003] With the rapid development of the photovoltaic industry and the increasing number of photovoltaic power stations, the operation and maintenance technology of photovoltaic power stations has gradually become a research hotspot. For the scattered and complicated operation data, status data, environmental data, etc. of photovoltaic power plants, there is a lack of effective analysis methods to statistica...
