摘要
以新疆某电站为研究对象,通过模拟光伏组件表面不同积雪厚度,得出积雪对光伏组件发电量的影响特性,当积雪厚度达到6mm时,太阳光无法透过雪层照射到光伏组件表面,光伏组件发电量损失量为89.92%,电站停止向电网输送电能。阴天云量对光伏电站发电量影响明显,在少云天、多云天和全云天分别损失电量为24.87%、39.64%及69.24%。
Taking a power plant of Xinjiang as the research object, the author knows the effect of snow on PV module sur-face by simulating snow with different thickness. When the thickness of snow reaches to 6 mm, sunlight cant get to the PVmodule surface and the generating capacity of PV modules will lose 89.92% , which leads to the plant stopping sending e-lectricity to power grid. Meanwhile, the effect of cloud cover on the generating capacity of PV power plant is obvious. In acloudless, cloudy and all - sky cloudy day, the loss of generating capacity is 24.87%, 39.64% and 69.24%.
