摘要
研究智能变电站采集器与合并单元传输系统中光电模块的老化特性问题。设计了一种基于8472协议的实验系统,对光电模块进行加温实验,采集光电模块的5个关键参数在温度变化下的采样数据,对采样数据利用阿伦尼斯模型进行计算,从而评估光电模块的老化特性。计算结果表明,实验所用某厂家光电模块工作寿命较长,与厂家技术文档中基本一致。
The aging characteristics of photovoltaic module between data acquisition system of smart substation and unit cell of transmission system are studied. An experiment system based on Protocol 8472 is designed to heat up the photovoltaic module and the five key parameters of the photovoltaic module are sampled in different temperatures. Then the sampled data are calcu- lated with Arrhenius model to evaluate the aging characteristics of photovoltaic module. The calculation results indicate that the photovohaic module from one manufacturer adopted by the laboratory has a longer operating life which is basically accordant with the technical documents provided by the manufacturer.
