The utility model relates to a solar energy road surface technical field, more specifically the test device that relates to a solar energy road surface electricity generation characteristic under test driving shadow that says so.

Background

With the gradual shortage of fossil energy and the increasingly prominent influence on the change of climate and environment, the search for clean and renewable energy has become the direction of joint efforts of all countries in the world, the basic trend of global energy transformation is to realize the transformation from a fossil energy system to a low-carbon energy system, the development of clean and renewable energy has become the core content of energy transformation promotion and an important way for coping with climate change in many countries, and the development of clean and renewable energy is also one of the important measures for promoting energy production and consumption revolution and energy transformation promotion in China.

The solar road surface based on the photovoltaic power generation theory can be used as a new energy collection mode to generate power in a clean and pollution-free mode. The solar pavement can meet the requirement of developing new renewable clean energy, and also provides wide electric energy conversion application of traffic engineering technology, intelligent road equipment, electric automobile power supplies and the like.

However, photovoltaic power generation is susceptible to environmental factors resulting in a reduction in its efficiency. Among them, shadow shielding is one of the main causes of power loss, and includes clouds, buildings, trees, silt and dust, etc. When a local shadow is formed on the photovoltaic module to shield, the illumination intensity distribution on the surface of the module is uneven, so that the output performance of the module and the photovoltaic array is seriously attenuated, even a hot spot effect is formed, the module is damaged, and the output power of a system is sharply reduced. Therefore, how to reduce the influence of the local shadow on the photovoltaic system becomes one of the hot research contents in the industry.

For a roof or other typical solar photovoltaic power plants, influence caused by dynamic shadow does not need to be considered, the solar pavement also plays a role in transportation while providing clean energy, the solar pavement serves for driving and pedestrians, and moving shadow is caused by vehicles or pedestrians in the motion process, which is a dynamic process, so that the output power of the solar panel is suddenly reduced or increased to form rapid fluctuation, the power generation amount of the solar panel is reduced, the performance life of the solar panel is damaged, and the calculation of the power generation efficiency of the solar pavement and the pavement of the solar pavement on a public road need to be considered.

In addition, in the previous research of shading the photovoltaic module by the shadow, two extreme modes are adopted for static shadows formed by pollutants such as leaves, dust and the like, wherein one mode is full coverage, and the other mode is non-coverage; for dynamic shadows, low-speed clouds and leaf shadows formed by wind blowing or shadows of objects such as buildings, trees and the like can generate slow deviation along with different solar altitude angles and azimuth angles, the moving speed of the dynamic shadows is very low, so the dynamic shadows can be considered as local static shadows, and the research method mainly applies numerical simulation, but the method has certain error with actual conditions, does not have real-time performance, and cannot reflect the actual conditions. For the fast dynamic shadow of the solar road surface, the conventional static or low-speed dynamic shadow method cannot be applied, and no suitable test device or method can be used for effectively testing the fast dynamic shadow at present.

Therefore, it is an urgent need to solve the problem of the art to provide a testing device capable of effectively testing the influence of the dynamic shadow generated by the vehicle moving on the power generation performance of the solar energy road surface in real time.
