基于实测数据的光伏电站容量配置系数优化

Optimized Coefficient of Capacity Configure Based on Measured Irradiance Data for PV Power Station

摘要: 近年来，部分光伏电站采用光伏组件与逆变器容量配置系数大于1的设计理念，其配置系数的选择多根据经验值，鲜见理论分析。将在某地的实测辐射值的基础上，再综合电站不同的效率、投资的情况，根据价值工程完成电站新增发电量与新增投资之间的关系分析，最终确定合理的配置系数，为类似工程提出参考。

Abstract: Some PV station adopting the design philosophy that the PV module's and inverter's capacity ratio higher than 1 in recent years, the definition of ratio is based on the designer's personal experience, lack of theory analysis. In this paper, based on the measured irradiance data in a certain place, analysis the ratio between the added generation of PV station and investments based on different efficiency and price of PV station by using value engineering method. At last, we give the optimized PV module's and inverter's capacity ratio in the certain palace for the similarly projects.
