摘要
With the large-scale construction of photovoltaic power plants, the physical characteristics of the near-surface layer change accordingly. The turbulence activity as the way of interaction between the earth and the atmosphere is also affected by it. As a new form of solar power generation, lake photovoltaic power plant plays a vital role in energy application. In order to understand the characteristics of local turbulence in lake photovoltaic power plants, the observed data of the photovoltaic power plant from July to November 2021 in Yingfang Village, Fengyu Town, Yangzhong City, Jiangsu Province, were used in this study to investigate the turbulence characteristics and the variation rules of stability. The results indicate that: the installation of photovoltaic power plant enhanced the turbulence intensity, and showed as Iv> Iu> Iw, which had a certain influence on the local airflow. At the same time, the photovoltaic power plant promoted the enhancement of turbulent kinetic energy and friction velocity, and significantly increased the local momentum and heat transport. The momentum transport coefficient CD=13. 36×10-3, and the sensible heat transport coefficient CH=6.01×10-3. The instability of near-ground atmosphere on photovoltaic power plant was enhanced in the daytime, and conversely, it was enhanced stability at night. After the classification of stability, the near-ground atmosphere on photovoltaic power plant was mainly concentrated in neutral and near neutral, accounting for 75.11%.
