摘要:
该测量方法用于测量估算光伏阵列的理想发电量,进而估算光伏阵列的发电量损失百分比。该测量方法基于太阳辐照强度与光伏阵列功率趋势一致,利用理想条件下太阳辐照强度服从正态分布的特点,运用搞高斯拟合和多项式的拟合方法计算光伏真理的理想发电功率曲线,计算其理想发电量,进而计算对应的发电量损失。综合考虑功率测量的准确度和计算误差,该方法的计算误差在1%以内,可作为光伏阵列发电量损失的分析的应用方法。
Abstract:
This measurement method is used to measure and estimate the ideal power generation of photovoltaic array, and then estimate the percentage of power loss of photovoltaic array. Based on the fact that the solar irradiation intensity is in accordance with the power trend of photovoltaic arrays, this measurement method utilizes the characteristic that the solar irradiation intensity obeys the normal distribution under ideal conditions, calculates the ideal power curve of photovoltaic truth by means of Gauss fitting and polynomial fitting, calculates the ideal power generation, and then calculates the corresponding power generation. Loss. Considering the accuracy and calculation error of power measurement, the calculation error of this method is less than 1%. It can be used as an application method of photovoltaic array power loss analysis.
