随坡安装山地光伏电站阵列间距的计算
|
摘要
推导出了随坡安装山地光伏电站阵列间距的计算公式,给出了光伏阵列在水平面投影参数的计算公式,并开发出了光伏电站阵列布置设计软件。以青海共和项目点为例,对公式计算和PVsyst软件模拟结果进行了对比分析,结果表明两者吻合度较高,间接地验证了公式的准确性。该研究的成果可用于指导光伏电站阵列间距计算和阴影分析等方面的工作。
Formulas for calculating the array spacing of mountainous PV power stations mounted on slopes are derived,and the calculation formulas for the projection parameters of the PV arrays on the horizontal plane are given. A software for the layout of the PV power station arrays is developed. Taking the project located in the Gonghe,Qinghai as an example,the formula calculation and PVsyst software simulation results are compared and analyzed,and the accuracy of the formula is verified indirectly. The research results can be used to guide the calculation of array spacing and shadow analysis of PV power plants.
