AI Technical Summary

Technical Problem

Existing methods for testing the albedo of photovoltaic power plants cannot accurately reflect the overall albedo of the power plant, nor can they quantify the contribution of surface albedo to power generation efficiency. Fixed meteorological monitoring stations have limited coverage and cannot conveniently monitor atmospheric temperatures at different altitudes.

Method used

The method of drone patrol is adopted. The drone synchronously collects spatial position, flight attitude data, incident radiation intensity and reflected radiation intensity. Combined with aerial imagery, a digital orthophoto map is generated to determine the non-overlapping flight zone area and calculate the overall albedo of the photovoltaic power station.

Benefits of technology

It has achieved high-precision and high-efficiency measurement of the albedo of photovoltaic power plants, significantly improving measurement accuracy and efficiency, and providing technical support for the refined management and energy efficiency assessment of photovoltaic power plants.

Abstract

The present application belongs to the technical field of new energy detection, and relates to a method and system for testing albedo of a photovoltaic power station patrolled by a UAV. The method comprises: collecting spatial position coordinates, flight attitude data, incident radiation intensity, reflected radiation intensity and aerial images of each measurement point; determining validity of the measurement points according to a preset flight attitude angle threshold value, and eliminating invalid measurement points whose flight attitude data exceeds the flight attitude angle threshold value; calculating single-point albedo based on the incident radiation intensity and the reflected radiation intensity of the valid measurement points; performing geometric correction on the aerial images based on the spatial position coordinates and the flight attitude data to generate a digital orthographic image map; determining non-coincident flight strip regions based on the digital orthographic image map; and calculating overall albedo of the photovoltaic power station based on the single-point albedo of the valid measurement points in each non-coincident flight strip region. The present application realizes high-precision and high-efficiency measurement of albedo of a photovoltaic power station.
