Abstract

The invention relates to a solar power generation efficiency estimation method. A plurality of images obtained at a plurality of time points in a time sequence are analyzed to obtain a gray scale average value of each image and a variation corresponding to each time point. And obtaining a stable time zone from the time point based on the gray scale average value and the variation amount. And then calculating a solar energy evaluation index corresponding to the stable time zone.

Description

technical field [0001] The present invention relates to a method for evaluating the efficiency of power generation, and in particular to a method for evaluating the efficiency of solar power generation. Background technique [0002] Solar power is an emerging renewable energy source. Solar technologies are broadly characterized as passive or active ways to capture, convert and distribute sunlight. Solar power generation is often characterized by unstable sunlight, which makes it difficult to accurately evaluate the power generation efficiency of solar power plants. The traditional method calculates the amount of sunshine A in a specific period by installing a sunshine meter, and then compares it with the power generation B in a specific period obtained from the electric meter, so as to obtain the power generation efficiency (power generation / solar radiation). [0003] However, if the operating environment of the solar power plant is harsh and the signal interference is ser...
